--------------------------------------------------------------------------------------------------------------------

Nineteen year old Elizabeth, or Beth as she was called sat on the couch next to her eighteen year old brother Jimmy. Across from them in the small office behind the desk sat Sister Kristine, the math teach and student therapist at the small Catholic school they attended. Beth was a senior and Jimmy a junior, they were both a year older then all their classmates because their mother thought starting them later in kindergarten would give them a leg up through the years.

The extra year didn't help in the experience department. They were very sheltered and lived within an extremely strict Catholic household. Neither were allowed to really date, only occasionally go out with a group of friends and then had a solid 11pm curfew. Needless to say, they were both virgins and both very sexually repressed, not being able to go through the normal teenage experiences.

Sister Kristine was young, maybe thirty or so years old. She was brilliant though, along with her theology training she held a teaching degree, a Master's in mathematics, and was a certified Therapist with a focus on adolescence and young adults. And she was beautiful.

She had long, dark hair that was always in a bun. She had strikingly gorgeous dark eyes, a beautiful smile and an amazing body, which was not always easy to see as she always wore a very conservative suit consisting of a white blouse, a blazer and a knee length skirt in either navy or black and pantyhose to match whatever color suit she wore. Many a night while alone in bed Billy would take out his sexual frustration fantasizing about the gorgeous nun.

"So, Beth, Jimmy, I'm sure you know why you're here meeting with me today." She looked across the desk at the siblings. Beth with dark curly hair and blue eyes and Jimmy with blonde curly hair and the same color eyes. Unlike most phony stories you read on Lit, they were not the hottest cheerleader or the big stud jock. They were just normal, not unattractive by any means, just normal kids.

They both dropped their eyes at her stare, embarrassed to look at her. "Come on, the best way to get to the bottom of this is to just rip off the band-aid and admit what went on."

Beth spoke in a whisper, "Our mom caught us."

"Caught you what?" The Nun's voice was soft but stern.

"Kissing," Beth said, barely audible.

"I'm sorry Beth, please speak up." Jimmy had not lifted is eyes once during this.

Beth lifted her eyes, her sparkling young blue eyes looked directly into the stunning dark eyes of Kristine. "Our mom caught us kissing each other."

Sister Kristine leafed through some notes, "Ah, here it is, according to the phone conversation I had with your mother she caught you, and I quote, with your tongues in each other's throat and your hands petting each other like disgusting heathens.''

Again Beth dropped her eyes to the floor. "Look at me... both of you." They looked up at the young nun, their faces flushed.

"Was this the first time you've done something like this?"

"Yes." Jimmy whispered.

"Why?" Kristine asked.

Beth spoke again, "Neither of us have ever been with anyone. We... we just wondered what it would be like to know what, um, making out felt like."

Kristine addressed Jimmy, "Well Jimmy, was it everything you thought it would be?"

"What do you mean Sister?"

"Making out with a girl. Did you like it?"

"I... I guess so."

"Even though it was with your own sister?"

He glanced at his sister, "Yes, even with my own sister."

"Beth? What about you?"

Beth's voice suddenly got a little firmer, more confident, "Yes. Ok? Yes I liked it... no, I loved it. You have no idea how frustrating it is to be nineteen years old and treated like child. And yes, I love that my first time feeling this was with my brother, he's the only boy that ever looks at me with..... with that look."

A small smile crossed Kristine's lips. "Well, I appreciate the honesty. Um, exactly what looks does your brother give you?"

"I don't know it's like he, um, is checking me out. I catch him looking at my legs a lot. Sometimes trying to look down my shirt and the way he looks into my eyes and smiles at me... it makes me melt. It makes me feel like I'm wanted."

Sister Kristine stood and walked around to the front of her desk and pushed herself up so she was sitting on it, then crossed her legs, her skirt riding up a bit exposing her black pantyhose covered legs. Jimmy couldn't help himself and stared at the young Nun's legs as she crossed them. She smiled to herself as she saw his eyes.

"Ok, so now we're getting somewhere. I'm going to start asking some questions and I want honesty no matter how, um, hard things may get." She seemed to make the word 'hard' longer and slower than it should have been. "The only way to get to the bottom of all this is to let all our true feelings out in the open. Maybe it will relieve some of the frustrations you both seem to carry. But first, I want to be completely open with you guys. Do you have any questions for me before we start?"

Kristine reached back and undid her bun shaking her hair loose, it fell down around her shoulders. Then she slipped off her suit coat, revealing her crisp white blouse. "There, now you can look at me as a friend, just a casual friend trying to help you. Not some strict nun, ok?"

They nodded.

"Ok, I guess I have a question for you Sister."

"Ok, Beth, what is it you'd like to know?"

"Well, how can you help us? I mean how can you help figure out things of a, um, sexual nature when you're a nun. Didn't you take some vow of chastity? What do you know about sex other than what you read in books?"

"Ok, well, that is a good question. So, I haven't always been a nun. When I was younger, around your age Jimmy I was quite, well, promiscuous. I was with as many boys as would have me. I was for want of a better word addicted to sex. The old joke is, if I had as many dicks sticking out of me as in me I'd look like a porcupine." The siblings looked shocked at her language as she gave a soft laugh at her bad joke. "Eventually it caught up with me and my parents were to say the least horrified at all the talk so at the age of nineteen I was made to join the convent. Two years later, at the ripe old age of twenty-one I was a full on nun."

"Yea but, you're also a teacher and a therapist, how did that happen?"

"Good question Jimmy. You can't just be a nun. You have to have a vocation. I had always wanted to be a teacher and I was forever a math nerd so I was allowed to enroll in college. I got my teaching degree and my Master's in math in only three years. Those three years though, wow! Do you know how many guys are on a college campus? Just because I was now a nun didn't mean I wasn't interested in sex any longer. God, you wouldn't believe how many college guys got off by having me wear my nun habit while they, uh, fucked me. And truth be told I got off on it too. Dirty talking nun while having sex, that's some serious fantasy shit right there."

The siblings both went wide eyed at her use of the vulgar words. "Um, Sister Kristine, are you sure you should be talking like that in front of Jimmy and I."

"Sorry if my words are a shock, when I talk about sex I tend to really let myself go." She made an 'oh well' motion with her hands. "So anyway here I was only twenty-four now, a nun, a certified math teacher and holding a Masters in math. So I did some deep inner reflection and thought about my addiction to sex, which for me wasn't a problem, I loved sex and still do actually, and I obviously just don't get it as much anymore." She laughed softly, "I thought about others though, young people that may actually have a mental and physical problem with sexual activities so I took a course in adolescence and young adult therapy with a focus on sexuality and became a certified Therapist. So, long story short, yes Beth, I feel I am very qualified to discuss items of a sexual nature with you two."

Beth seemed satisfied with that. "Ok, I guess we can get started then. Right Jimmy?" He nodded at his sister and they both looked expectantly at Sister Kristine.

Sister Kristine took a deep breath and started. "Ok, first question... Jimmy, do you masturbate?"

"What??!! Sister Kristine, this seems inappropriate."

"Ok, look, it may seem like an odd question coming from a nun but, remember, I am trained in adolescence and young adult therapy covering all sorts of issues and concerns... including those of a more sexual nature. So, come on, complete honesty remember?"

"Yes, Sister, I do but..."

She cut him off, "no buts, it's ok to be a normal boy."

"When you masturbate, who do you think about?"

Now Beth's eyes went wide in shock, especially as he answered, "I, oh God, my sister a lot but not always."

"Not always? Who else then, other girls at school?"

"No... I... I can't say Sister Kristine, please."

"Yes, Jimmy you can. Remember I'm trained to help young people, nothing will shock me."

"You." His voice barely audible.

"I'm sorry what?"

"You... oh God I'm so bad, I'm so sorry Sister. I think about you and Beth, you're the only two girls I ever fantasize about." He looked like he could cry. Beth sat there in shock.

Kristine stood and walked over to Jimmy and rubbed his back, "It's ok Jimmy, it's natural, and like your sister said, it's nice to feel wanted and looked at like a woman instead of some stuffy old nun." She went back to her position, sitting on the front of her desk, this time it seemed she purposely allowed her skirt to slide even higher.

"Ok, now you Beth, do you masturbate? And who do you fantasize about?"

"Yes, Sister, I do. I only think about one boy when I do it," she looked at Jimmy, 'It's you Jimmy, it's always you in my fantasies."

"I love the openness and honesty. As long as we're being honest, I want you to know, masturbation is not a sin, regardless what your mother may have told you. It's very natural, as a matter of fact I do it every night after my nighttime prayers."

Both siblings seemed to visibly relax as she told them that. Almost like a weight of guilt was lifted from their shoulders.

"So, your mom caught you two making out. How did it start? Beth, you first."

Beth shifted uncomfortably, "we were just sitting on my bed talking, like we always do. Just about school, and life, what movie to rent this week, nothing major. Out of the blue Jimmy asked me if he could ask me a question which, he's my brother so I said sure. He asked me if I ever kissed a boy."

"And what did you say to him?"

"No, never. I've held hands with boys at school and slow danced once or twice but that was it. We don't get to go out much."

"That's a shame, you're missing the best years of growing up. So, then what?"

"He asked me if he could try it, kissing a girl I mean, with me. It gave me butterflies since he's been my only fantasy. So, I turned to him and we just stared at each other for what seemed like hours but was really just a few seconds and he leaned in and pressed his lips to mine."

"Jimmy, tell what it felt like the first time you kissed your sister."

Jimmy looked at Sister Kristine and gave a shy smile, "It was the greatest feeling I ever had in my life." Beth sighed softly and smiled when she heard her brother say that. "Once I had one kiss I couldn't stop and it felt like neither could she. Soon we were laying on the bed next to each like really, you know making out. Like a boy and girl would. Her tongue tasted and felt so good in my mouth. And the way she took my tongue into hers. It was amazing."

"So, when you two started making out did you get aroused?"

Jimmy blushed, "I, maybe..."

Beth took over, "He did Sister, God was he aroused and I let my hands roam all over him and his.... thing in his pants."

"Jimmy, did your hands, uh, roam over your sister?"

"Yes, everywhere. I was touching a girl everywhere for the very first time."

"Beth, how did that make you feel?"

"Excited, like the type of excited I get when I masturbate."

"So, your vagina was getting wet? And Jimmy your penis was getting erect?"

They both nodded and gave each other a shy smile, blushing.

"So you two were enjoying each other as a girl and boy should and your mother..? What?"

"We didn't even realize she had came home. She stormed into the room and grabbed Jimmy and threw him on the floor and then slapped me across the face. Then she leaned over and slapped him so hard like four times. She called him a lecherous sinner, said he was taking advantage of me, and then told me I was like all the other whores at school. She locked us in our bedrooms and told us to pray that God might forgive us for our.... what did she call it Jimmy?"

"She said we were disgusting incestuous freaks."

Sister Kristine sighed deeply, bowed her head and paused, "Freaks? Absolutely not. Whore? Not a chance. Incestuous? Maybe a little," she giggled. "I think you two were robbed of a magical moment that should have been special for you both." The siblings looked at her, confused. "I'd like to take this time to let you get that special moment back, would you like that?"

"What do you mean Sister?" Beth looked at Jimmy and then back at the Nun.

"Remember complete honesty, which includes me, as your therapist. I would love to watch you make out. Watch that special moment between a boy and girl when they realize how much they love and want each other. Would you do that for me?"

"I'm not sure this was what our mother sent us here for Sister. I thought you were supposed to cure the dirty thoughts I have for Beth and her for me."

Sister Kristine clapped her hands together and smiled, "Ok, therapy session is over." The brother and sister looked confused and started to stand to leave. "No, no that's not what I meant. Sit please. So, I've counseled a lot of young people, male, female and couples and in the first few minutes I can usually tell if they have a problem that needs help or if they just need a bit of a push to ah, let's say get over their hesitation and just go for it sexually. I can see, you two don't need help in a therapy sense but you do need help crossing that forbidden line and doing what you both want.

Beth slid her hand over and interlocked her fingers in Jimmy's hand.

"Jimmy, finding someone so attractive that you lust after them non-stop is not dirty, it's natural, and from what I've seen in this first few minutes, you two are in love, in lust and so beautifully attracted to each other it would be a sin to keep you apart. Tell you what, Beth, stand up, in front of your brother."

Beth stood, she was wearing a pair of cut off jean shorts and a white tee shirt, cute white socks and tennis shoes on her feet. Jimmy let his eyes slide up and down his sister as she stood.

"That's good Jimmy, take her all in, she is well worth looking at and if I may say... well worth lusting over." Beth looked over her shoulder at Sister Kristine and blushed.

"Now, Jimmy tell your sister what you find so desirable about her. And I mean everything you like and lust after when you look at her."

"I love her hair, how soft it is and..."

"No wait, you're not telling me you're telling her. Talk to her like I'm not here. Ok, now go on."

He started again and Sister Kristine took notes as he spoke. "Beth, I love how beautiful your hair is. I love how your eyes shine and seem to smile when you look at me. I love your body, when I felt it for the first time the other day I thought I was going to, um, ejaculate in my pants I was so excited. And your legs, oh my God, Beth your legs are so sexy and when you wear a skirt and pantyhose I just want to stare at you all day. And your butt, God you have a nice butt. I just think you are the hottest girl in town and I want you so bad."

Beth stood there, staring at her brother speechless. "Ok, well Jimmy that was very, very eye opening. Beth? Would you like to have a turn at this exercise?"

"I, yes Sister, I would."

"Ok, switch spots, Jimmy you stand in front of Beth."

Jimmy squirmed, "I don't think I can stand up right now." He shifted uncomfortably.

"It's ok Jimmy, you're aroused. I get it. Just stand up, don't be embarrassed. Let Beth see what affect she has on you"

He stood, the bulge running down the leg of his khaki shorts was to say the least impressive. He tried to cover it with his hands but not before his sister and Sister Kristine saw it in all its glory. The sexy young nun ran her tongue quickly over her lips as she stared it.

"Well, Beth, apparently your brother finds you extremely attractive. Ok, now tell Jimmy what makes you fantasize about him constantly."

"I don't know I just think you're cute, and yea you're not a big stud jock but you have a nice body. I love your eyes and the way you look at me and yes, you have a nice butt too," she giggled, "and apparently you have a nice penis." Her eyes darted to the still full bulge.

"Wow, such honesty, you two are so perfect together. It's a shame the world won't let two people so in love and lust be together just because they're brother and sister. But, the world isn't inside this room. What happens here, what is said here, and what I guide you two through sexually is between us three."

"But isn't lusting after my sister a true, serious sin Sister Kristine?" Beth nodded at his question.

"Tell you what Jimmy, I won't tell anyone if you won't. Now, we were going to get back to enjoying each other. Jimmy, Beth, sit next to each other, close, so close that I couldn't fit a piece of paper between you and start kissing. Show me what you were doing when your prudish mother so rudely ruined the moment."

The siblings blushed and looked at the nun then each other nervously. Beth took the lead, she leaned in and kissed her brother, a soft gentle kiss at first then as if a switch went off they were on each other. Tongues swirled, hands roamed, soft moans filled the room. Jimmy massaged his sister's firm breasts as her hands ran down his leg and gripped the rock hard teenage shaft under his shorts. In turn he ran his hands up and down her long, smooth legs before letting one come to rest in the crotch of her shorts, his fingers pressed into the fabric causing her to moan loudly.

Through the moaning and kissing they heard whispered instructions. "Pull her tee shirt off Jimmy. Unzip his shorts Beth."

Jimmy pulled Beth's shirt up and off exposing her soft white bra, his hands went to her breasts immediately. At the same time Beth was pulling open her brother's shorts, reaching into them she felt, for the first time in her life, a boy's cock. The moment ended as quickly as it escalated as Jimmy moaned loudly and spasmed. Beth yanked her hand out, it was covered in thick, sticky, white goo.

"Oh my God Beth! I'm sorry, I'm sorry, I... I'm so embarrassed." He moved to pull his shorts closed.

"Wait! Don't do that Jimmy." He froze and looked at the nun. Beth, was staring intently at the mess on her fingers. "Just sit there and catch your breath, both of you. Beth, why don't you taste what's on your fingers."

"Taste? What...?"

"Do you know what that is? It's your brother's sperm. No, wait, let's learn how to talk when sex is involved, this is love, this is lust, this is pure animal attraction not some stupid biology class. Like I said, therapy is over, from now on I am giving you instructions on how to pleasure each other and during the course of those instructions I may take the opportunity to have some fun with you both if that's ok." They nodded enthusiastically. "The stuff on your hand is cum, your brother's cum. Cum is also a verb, when he shot it over your fingers he was cumming or you made him cum. Your hand was wrapped around his cock, penis is for class, and cock is for sex. When you masturbate and have an orgasm you also are cumming or you came. You play with your pussy, vagina is once again for the classroom and if you want to get really into it you can call it your cunt, or twat. Now, taste your brother's cum. I bet you'll like it.... God knows I'd love to taste it."

That made them both look at her in shock and when they did they noticed she had unbuttoned the top three buttons on her blouse. She looked down at herself and laughed, "Oh, sorry you two had me so turned on had to play with my tits while I watched you, not to mention the puddle you put in my," she paused and smiled, "cunt."

Beth slowly brought her fingers to her lips and licked them, then sucked them moaning.

"Good isn't it Beth, fuck I haven't tasted a good load of young cum in so long. Shove you fingers back into his shorts, I bet there's plenty more cum all over that sexy young cock."

Jimmy moaned as his sister ran her hands back into his shorts and came back with more of the delicious stickiness, sucking it into her mouth eagerly.

"God it tastes so good," she moaned as she cleaned her fingers. Sister Kristine stood and walked over to them and boldly ran her fingers down Jimmy shorts coming back with a string of white cum. She slowly, while staring into his eyes, sucked it seductively off her fingers.

"Beth, would you like to see your brother naked for the first time? And Jimmy, you want to see that hot body you jerk off to don't you?" They both nodded. "Well then stand up, I want to watch you two undress each other. And make out while you do it, kissing is a very sensual and personal thing while you enjoy each other sexually. Oh, by the way, how do you like our session so far?" She laughed as she spoke.

"I love it!" Jimmy said eagerly, "can we have "therapy" next Saturday too?" He made air quotes with is fingers.

"Oh, I think I can convince your mother that we have a lot more work to do to cure her dirty, lustful, sexy, horny, oh so fuckable, incestuous children."

Beth and Jimmy laughed as they embraced and started deep French kisses. They found their hands easily undressing each other. Jimmy unsnapped her bra and pulled it off. Beth pulled off his shirt and pushed his shorts down so they pooled at his ankles. His young cock, again rock solid on full display as her brother licked and sucked the stiff nipples on her firm, ripe nineteen year old tits. His fingers found the button and zipper of her cutoffs and as he pushed them down he slid to his knees, the soaking wet crotch of her white cotton panties in his face.

The loud moans caught his attention and out of the corner of his eye he saw Sister Kristine had completely taken off her blouse and was squeezing her breasts through her bra as she watched. "God Jimmy, do it. Take those fucking panties off and look at your sister's beautiful young cunt."

He hooked his fingers in the waistband and looked up at Beth with eyes full of lust and want. She smiled wickedly down at him and nodded. He slowly peeled his sister's panties down for what would be the first of many, many more times and gasped. Her pussy was perfect. The pink petals slightly open from arousal and clear moisture leaked from her. She had a neatly trimmed triangle of dark brown fur. He leaned in and inhaled deeply.

"It's beautiful Beth, more beautiful than I ever dreamed."

Beth moaned and giggled, "Do you like the way I trim it Jimmy? I keep it that way just for you, or at least always hoping it would be for you."

"God you two are perfect. Beth your sexy young cunt looks so fucking good. And Jimmy, fuck me but that cock is better than any cock I've seen on an eighteen year old boy. Now taste her Jimmy, taste your sister's pussy for the first time"

He pressed his face forward and his tongue darted out and slid the length of Beth's slit. She moaned loudly as her knees seemed to buckle. "You better sit Beth, I think your brother is about to give you some serious fireworks," The nun laughed.

Beth fell back flopping down on the couch and instinctively opened her legs. Jimmy was possessed. His fingers and mouth worked her over like he hadn't eaten in days. He was a natural, not perfect but he took to eating pussy like an old pro.

Sister Kristine had now removed her bra and was yanking on her big hard nipples, her thirty year old breasts firm, ripe, and full. She bunched her tight skirt up trying to get at her cunt with one hand as she watched brother and sister go at it. "God damn eat the cunt Jimmy. Make you sister fucking cum all over your face you sexy fucker. Jesus fucking Christ you two are making me so fucking horny."

Beth rolled her head back and forth on the back of the couch, "Yes! Fuck! God Jimmy, so fucking good. Eat me baby brother. Eat my God damn mother fucking cunt you hot little fucker." Suddenly her whole body shook and her ass flew up off the couch as she wailed, "OOOOOOOOOO FUUUUUUCCCKKKKK YES!!!!!!" A stream of sticky, clear fluid squirted out of her all over her brother's face. Jimmy drank and slurped and licked as much of the amazing nectar as he could. Beth collapsed in a heap, breathing hard while her younger brother remained kneeling between her legs, gently licking and kissing her cunt and thighs.

"Holy shit Jimmy! You just made your fucking sister cum so hard. Are you sure you've never eaten a girl out before?"

Jimmy looked back at Sister Kristine and his eyes went wide. She was now completely naked except for the sheer, black pantyhose she wore. Her tits were amazing, her legs perfect and between those legs was a huge wet spot soaking her sexy pantyhose. "No Sister, really that was my first time," he smiled sheepishly.

"Well, you sexy little fucker... I better get to enjoy your second time. Deal?"

His rock hard teenage cock twitched at the thought of it, "God yes Sister Kristine, I'd love to eat that sexy nun pussy."

"Beth, you wouldn't mind sharing your hot little brother with me would you?"

"Of course not," she said hoarsely, still catching her breath, "I'd love to watch him do to you what he just did to me."

Sister Kristine stood, Jimmy drooled at the sight of her body. Like he said, these were the only two girls he ever fantasized about. "Jimmy, sit next to your sister. Press that hot young body up against her sexy, delicious body."

He slid up on the couch and wrapped an arm around her shoulder as she draped a long leg over his legs. They turned and deeply kissed. "God Jimmy, that was amazing. I love you so much. Thank you." Her fingers gently slid up and down her brother's throbbing teenage cock.

As the nun stood before them, her incredible body on full display she smiled sexily, "I think we need to address the other elephant in the room, or should I say, the elephant sized cock that needs attention.

The horny nun leaned over and deeply kissed Jimmy, his young hands immediately went to her perfect, full, womanly breasts. Meanwhile, Beth leaned forward and started running her hands up and down the sexy pantyhose covered legs and ass of Sister Kristine. "God you have sexy legs Sister, I can see why Jimmy wants you so bad."

Sister Kristine broke off her kiss with Jimmy moaning, "I've had a few hot threesomes in my life but I've never been shared by a brother and sister and I can't wait to feel that thick eighteen year old cock in my cunt but not until after I help you take each other's virginity." The siblings both moaned as she said that. "But, before we get to everyone fucking each other, I think you should learn how to suck your brother's cock. Jimmy, would you like Beth to give you a blowjob?"

"Oh my fucking God yes! It's been a fantasy of mine for so long."

Kristine slid to her knees at Jimmy's feet. "Come on Beth, get that sexy ass down here. I'm going to teach you how to be a world class cock sucker. By the time I'm done training you your little brother will be putty in your hands, willing to do anything for you to feel your mouth on his cock." She smiled proudly at herself.

Beth knelt next to Sister Kristine, their naked bodies touching, her pussy dripped at being so close to the sexy nun while staring at her brother's perfect cock. The nun turned to her and kissed her, hot, deep, wet tongue kisses. Beth's eyes went wide at her first girl girl kiss then softly closed as she got into it. As they made out they felt each other everywhere. Kristine's fingers probed Beth's cunt as Beth returned the favor.

"Holy shit! I can't believe I'm watching my two fantasy women together." He slowly stroked himself as he watched them.

"Have you dreamed of me with your sister Jimmy?" Her voice was dripping with seduction.

"Yes, God yes."

She kissed his bare thigh and smiled up at him, "Well, I guess I better make those naughty dreams come true." Beth buried her face in Sister Kristine's neck and nibbled as she felt every inch of the hot nun's body.

"Ok, ok, Beth, as much as I want you to continue, we have a job to do... a blowjob. Your brother's cock looks so fucking suckable. Let's get those lips of yours doing what he craves."

Beth sat back on her heels and nodded, "Ok Sister, teach me. I want to please Jimmy in every way I can."

"Ok, so first, you need to get to know his cock. Before your mouth gets involved you need to use your hands. Feel it, run your fingers all over it. Learn every ridge, every curve, feel how it fills your hand as you wrap your fingers around it and slowly slide up and down. Of course you want it to be comfortable to him so you want to keep it and your hand wet." She pulled her hand away from Jimmy's cock and spit a wad of saliva into it then went back to stroking the young, throbbing. fuck stick.

"Oh fuck, that does feel better with the spit on it. Fuck Sister, your hands are amazing."

She smiled at Jimmy as she continued, "Ok, Beth, now we also have to take care of these nice, full, teenage balls. Cup the sac gently, softly massage them like this as you stroke him with the other hand."

Jimmy closed his eyes and lay his head back moaning as the sexy nun

massaged his cock and balls. "Ok, Beth, your turn. Learn his cock. Touch it. Make it yearn for your touch." Beth's eyes were locked on her younger brother's cock as she reached her fingers out.

Her soft finger tips slid up and down and all around his cock. She softly massaged the spongy mushroom top. Wrapping her fingers around the base she slowly slid her hand up and down.

"It's so soft and rock hard at the same time. And it's so warm."

"Don't forget the spit baby girl, always try to keep your hand a little wet as you do this. And you're right, it is amazing how it can be so hard and the skin so soft. And the warmth... that's your brother's lust showing. His cock is hot for you. Ready for you. Needy for his big sister." She leaned over and gently kissed Beth's cheek, "You're doing so good. I can see in his eyes how much he's enjoying your touch. Are you ready for the next step?"

"Yea, I guess so. Will you show me what to do?"

"Unfortunately not Beth, I don't want your brother's first blowjob to come from me. It has to be you. It was always meant to be you. I'll guide you but the first mouth to taste that beautiful cock should be the girl he loves the most, his gorgeous older sister." Beth blushed at the nun's words.

As her hands continued to explore her brother's cock she turned to Sister Kristine and spoke in a soft whisper, "I just have to say this is still so surreal. The same proper nun that I see in church and that teaches at school is training my brother and I how to fuck." She shook her head as if to wake herself from a dream.

"Well, Beth, Jimmy, I am three people I guess. First and foremost I am a nun, giving myself to the service of God and fulfilling all the duties of my vows. Secondly, yes, I am a teacher. Molding young people's minds, helping them get ready for success in the future. Thirdly, I am a nasty, cock loving slut, and teaching you two how to enjoy sex as much as I do is a huge turn on for me. Now, let's get to that cock sucking shall we?"

"Yes please!" Jimmy laughed, "somebody please suck my cock before I explode!"

"Start with your lips Beth. Kiss it. Kiss it all over. Soft, gently kisses. Let your brother know how much he means to you. Show him how much you love him and his perfect cock."

Beth gently kissed her way from top to bottom and back again, spending extra time on the tip. A string of precum attached to her lips and she flicked it into her mouth with her tongue. "MMM, that's tasty."

"That's his precum, it shows he's really getting turned on by you. Go on keep going, now add that nice warm tongue. Lick that sexy and cock and those nice full balls."

Beth swirled her tongue around the throbbing cock causing Jimmy to let loose a long low moan. She licked it like a lollipop, up and down and all around. Lowering her face she brought her mouth to her brother's ball. Kissing and licking the full sac as her soft hand stroked him.

"Wow, Beth, you're a natural. Keep going, show the cock some love. Fuck I can't say I'm not jealous, giving a cock this nice its very first blowjob. Now, softly suck his balls, let them fill your warm mouth while you continue to work the shaft."

She opened wide and let one fat nut slip into her mouth and sucked gently. Stretching the sac as she pulled back slightly. The with a pop she let it go and repeated the same with the other ball.

"Fuck me Beth. Don't stop please. I've never felt anything so incredible in my life."

Kristine ran her hands up and down Jimmy's legs and smiled at him, "You're a lucky little fucker you know that? Your sister is doing so good. She be sucking you like a pro within weeks... maybe ever days."

Beth pulled her mouth off Jimmy's balls and smiled shyly at Sister Kristine, "Am I really doing good?"

"Look at his face, that should tell you everything you need to know," The nun giggled. "Now, ready for the main event? Ready to suck that fat cock?"

"Ok, watch this.... this is what I want you to do to your brother's dick." She put her fingers together and wrapped her lips around the tips then slowly sucked them into her mouth, her cheeks caving in as she sucked deep. Then as if she were sucking a cock, she slid them in and out of her mouth, her sucking sounds loud, her cheeks sucked in deep.

Beth took Jimmy's cock by the base and wrapped her lips around the thick top. Slowly she sucked it in taking at least three inches into her mouth before pulling of with a slight gag. "It's so fucking thick. I can't take anymore than that." She went back to try again, gently bobbing now, sucking her brother, trying to take as much as possible.

"Fuck Beth, you're doing so good. God I love your mouth on my cock. Suck me baby, suck your brother's cock you sexy fucking goddess."

"Don't forget those balls Beth, gently massage his ball sac while you suck him. Coax all that hot young cum into your mouth. Do you want to cum in your sister's mouth Jimmy?"

"Fuck yes! Fuck I'm so fucking close. God damn you're a good teacher Sister Kristine."

"That's it Beth, suck it hard now, suck that fucking cock you hot little cock sucker. Make your brother's first cock sucking one he'll never forget. Come one slut, bob on that cock, suck the cum out your little brother you sweet, sexy, cum slut."

Beth bobbed faster as Jimmy started a low, slow moan.

"Beth. Beth. Beth. Oh fuck Beth, I'm going to..... FUCK!!!!!!" His cock thrust into his sister's mouth as he exploded. Beth's eyes were wide as her mouth filled with cum.

"Swallow it Beth, Don't waste that cum. Drink all your brother's cum down." She did her best as rope after rope shot from the eighteen year old cock until finally he slowed. Finally she pulled off and sat back on her heels smiling and breathing hard.

"Fuck Sister, do they always cum that much?" The nun leaned in and kissed Beth, "not always but a good blowjob can definitely coax a lot of cum out of a guy. I can't believe how amazing you did for your first time. I bet you'll be sucking that cock every chance you get. You wouldn't mind that would you Jimmy?"

"Jesus fuck I'll take a blowjob from my sister any time she wants to give me one."

Beth and the nun knelt on the floor at Jimmy's feet. "So, once Jimmy recovers shall we move on the the most important lesson of the day?"

"What's that," Beth asked.

"Fucking! I'm going to teach you two how to fuck and you're going to give each

other the ultimate gift... your cherries." She looked at the clock on the wall, "Oh shit! We only have a few more minutes. How long until that cock is rea.....?" She stopped when she saw, Jimmy was already at full mast again. "Fuck, I forget how virile an eighteen year old is! Alright you two, up on the couch."

Beth climbed off the floor and sat next to her brother. Their naked bodies wrapped together as one as they waited for Sister Kristine to guide them. "Now start loving each other. Kiss. Fondle. Do everything your sexually cold mother would hate."

They did as told. Kristine moaned softly as she fingered herself watching the loving siblings. "Beth, look into your brother's eyes, tell him what you want."

She stared deep into Jimmy's eyes and took a deep breath, "Jimmy, I want you to... I want you to fuck me. Please? Will you fuck your big sister and pop my cherry? Please be my first."

"I've wanted to fuck you for so long Beth. Just try to stop me!"

Sister Kristine grabbed a cushion on put it at the end of the couch. "Lay back Beth, rest your head on the pillow and open your legs for Jimmy." She did as instructed.

"Jimmy, kneel between your sister legs. Stroke that cock and show her how hard you are for her."

Jimmy looked at his sister and whispered, "I love you Beth."

"I love you too Jimmy. I'm ready for you."

"Now scoot forward Jimmy and run the head of that fat cock up and down her folds. See how she's opening for you. Her cunt is so ready for your cock. Beth open yourself with your fingers more." Beth did, revealing her bright pink interior and the tiny hole that would soon be stretched open by her brother's cock.

"Ok, Jimmy push in, just the head, let her get used to it." He pushed the head of his cock into his sister and they both moaned out in pure, sensual pleasure. "Ok, a little more baby, push that cock in a little further. Fuck this is so beautiful. I've never watched two virgins fuck for the first time."

"Ow ow! Fuck he's too big Sister." Beth's face was red, her breathing short and fast.

"No he's not Beth. Just let yourself stretch. Let your brother take you like I know you want him to. Jimmy, lay down now, get your body on top of Beth's and kiss her."

He held himself still, his cock ever so slightly inside is sister's pussy and kissed her passionately.

"Beth pull your knees back farther, hook your heels together around his back. Now, this is it, are you two ready?" They both nodded, their breathing rapid. "Beth this may hurt at first but once you get used to it you'll never want it to end. Jimmy, lift that sexy ass up a little and do it, slam that cock in hard and deep, pop that sexy cherry. Fuck your sister."

Jimmy pulled his ass back just a touch and rammed forward. His cock blasting through his sister's tunnel until he was balls deep.

"FUCK!!! FUCK!!! God damn it it hurts. It's too big Jimmy."

"Shhhh, it's ok Beth, relax and breath, yes it is big, most girls aren't lucky enough to loose their virginity to such and amazing cock. It's your brother, remember he loves you. You both want this."

Her words calmed Beth and she slowed her breathing. "Ok, ok, it's better. God he just stretched me so wide."

Jimmy was kissing her, softly whispering her name, "We're fucking Beth. we're finally fucking."

"Slowly now Jimmy, start pulling back and pushing in. Gently fuck your beautiful sister. As you get used to it you can speed up." Soon they were fucking in a perfect rhythm. Jimmy's body slapped against Beth's as he fucked her hard and deep.

"Yes, baby, fuck me. Fuck my cunt you sexy fucker. God I really love your cock."

"And I love your pussy Beth, so fucking tight, you're squeezing me so hard I don't think I can last much longer."

"Do it Jimmy, cum in Beth's cunt, fill your sister with that hot jizz."

"Fuck! Mother fucking shit! Beth I'm going to... ahhhhhh fuuuuuuccckkkk!!!!!" His cock filled her, thick gobs of hot cum flowed into her. As he came Beth's pussy squelched and spasmed and she came all over her brother's cock.

"Oh my God! Oh my God! Jimmy, you fucking made me cum! Fuck so good. So fucking good."

From off to side they heard another voice, "Mother fucker. Jesus Mary and Joseph I'm fucking cumming too!!!!" Sister Kristine had her hands between her legs, the crotch of her black pantyhose ripped open as she finger fucked herself while watching the brother and sister.

The three of them were silent. Sweaty bodies spent. The room smelled of sex and cum and cunt.

"Oof, Jimmy, I need you to move, you're crushing me." Beth was laughing. He rolled off his sister and his sticky cock popped out of her cunt. Followed by strings of cum. Beth slid her fingers through it and brought it to her mouth. Then repeated the motion and offered it to the horny nun who ate it greedily.

Suddenly a bell rang. "Oops! Therapy is over I guess," the naked nun sighed. "Come on, let's go into the washroom and freshen up. She climbed to her feet as Jimmy helped Beth to hers. The three of them went into the side room, a spacious room with a sink, towels and a toilet. Without hesitation Beth sat on the toilet and peed in front of the other two. They both looked at her amused.

"What? A girl's gotta go a girl's gotta go," she laughed. Together they cleaned each other, washing their bodies with the wet, warm wash clothes then drying each other off.

Back in the room as they sorted through the randomly thrown clothing and dressed. "You two were amazing together. I'm so glad I could help you become the lovers that you deserve to be."

"You weren't so bad yourself Sister," Beth smiled as she then Jimmy both kissed her deeply.

"So, I have you down for another Therapy session next Saturday at 1pm. Hopefully we can continue to make progress." She winked at them as they walked out the door.
