Family Vacation Pt. 07

This story involves incest and swapping. If that bothers you or is not something that you enjoy, please move on. If not, enjoy.

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

A family of four (husband & wife: Tom and Alice, kids: Maggie-19 and Mark-18) were 2 weeks into a month long vacation at a cabin by a lake, when Mark finally wore down his mother's defenses and she allowed him to make love to her. It was a beautiful and very fulfilling gift the mother gave to her son.

After watching his wife and son have sex, Tom made passionate love to his daughter Maggie. She had been trying to seduce her father for those two weeks and was finally rewarded with her father bringing her to multiple orgasms, before he unleashed his seed into his precious little girl.

Afterwards, Alice tricked her husband into fucking her and the once-distant couple rekindled their love for one another.

What was to happen on the rest of this trip was still undecided, but on this night, Tom returned to his daughter's bedroom, while Alice returned to the master suite, where her 18 year old son had fallen asleep, nude and while awaiting his mother's return.

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

As Tom approached closed the door to his daughter's bedroom, he still couldn't believe what had transpired this evening. He watched another man seduce and have unbridled sex with his wife. But not just any man, his own son. Mark had successfully seduce his own mother and made passionate love to her, culminating with him depositing a huge load of semen deep within his mother's vagina. The same vagina that he had passed through, some 18 years beforehand and a vagina that Alice now hoped that her son's large cock would visit many more times.

Tom looked at his daughter's nude body draped in just a sheet and felt fortunate that he was allowed to make love to his baby girl. A girl who had grown into an amazingly sexy young woman whose body drove men crazy with the thought of seeing, touching, tasting, and fucking. His bare cock had slid through the petals of her vaginal entrance, penetrating her tight pussy lips, to repeatedly slide in and out of his daughter's exceptionally tight vaginal canal. The walls of her pussy gripped his cock, as it passed through and the feeing in his cock was almost unbearable! The always respectful father marveled at how lucky he was to have a daughter who wanted to have sex with him.

Tom had never looked at his daughter with lust in his eyes or ever been inappropriate with her. He never checked out her amazing body or ever thought about her sexually. She had always been his little girl. But now, having felt the pleasure of his cock within her body, he knew that things would never be as innocent as it always had been. He now knew what his little girl's body looked like nude and how her snug cunt had willingly accepted her father's bare cock and semen deep within her.

He recalled the moment that they climaxed together and her vagina milked his seed from his balls, to fill her pussy completely, until it oozed out of the outstretched lips of her beautiful pussy.

Finally, he thought about the passionate sex that he and his wife had just experienced in the den of the small cabin. How she verbally teased him until he removed his cock from her vagina and came.

"Come to bed daddy." Maggie whispered seductively.

Tom came out of his stupor to see that his sexy daughter had removed the sheet and was welcoming her father back to bed with her. Her breasts stood firm and as his eyes followed the contour of her amazing body, they rested on the entrance to her womanhood. The labia of her moist pussy were slightly spread and his semen was still oozing from her cunt.

Maggie saw where his eyes now focused and spread her legs a little further apart. With her gaping pussy now exposed to her father, she spoke.

"Come on daddy. I want you to make love to me again."

Tom removed his robe and Maggie was pleased that her father's cock was fully erect once again. Upon focusing on it, she realized that it was glistening with vaginal fluid and a dollop of semen dripped from the tip.

"Did you just come from fucking mom?"

Tom could not respond.

Maggie rose from the bed and walked to her father. His cock throbbed at the sight of her amazing, nude body right before his eyes. As she approached, she reached out and grasped her father's slimy cock.

"Wow. Mom's pussy must've been sopping wet."

Tom flinched as his daughter's fingers caressed his cock. The mucus-like vaginal fluid coated his stiff cock and his daughter used her mother's vaginal fluid to masturbate her father.

"What was it like to fuck her after so many years of no sex between the two of you?"

"How did you know that we haven't had sex?"

"I use to finger fuck myself every time I heard you fucking mom. She's pretty loud when she cums and I haven't heard anything for probably 10 years. Besides, she pretty much told me that you two aren't having sex when she said that there's more to a relationship than having sex. Also, Mark probably couldn't have fucked her, if she wasn't in need of some cock."

Tom's cock pulsed at that revelation.

"You like the fact that your son fucked your wife, huh?"

Tom was silent, but once again his cock throbbed in Maggie's hand. Just then Maggie dropped to her knees and slid her father's cock into her mouth.

"Yum. You guys taste great! I'm glad that you finally gave your wife some of this amazing cock, but you're mine for the rest of the night and hopefully for the rest of this vacation"

The she proceeded to stroke and clean off her father's cock, with her tongue, lips, and mouth. Tom enjoyed his daughter's amazing fellatio skills but wondered where she learned it. His cock throbbed at the thought of her sucking off her boyfriend and his eyes closed as he thought about her mouth wrapped around another cock.

Just then, he remembered that tomorrow night she would be spending time with her brother. Instantly he came to that thought. Maggie looked at his face and realized that his eyes were closed and that he was probably thinking about something other than her lips wrapped around his cock.

She swallowed his entire load, then got back in bed.

"Come to bed daddy."

"Ok."

As they lay there, Maggie cuddled up to her father and caressed his flaccid cock.

"Daddy?"

"Yes, baby."

"Please be honest with me."

"Of course."

"What were you thinking about as I gave you head?"

"Honestly?"

"Yeah."

"I wondered who's cock you sucked before to be so good at sucking cock."

"Thank you daddy." She said bashfully.

"I'm serious."

"Randy taught me how to suck cock and to satisfy my man while doing it."

"Hmmm."

"Is that what made you cum?"

"Not really."

"What did?"

"Honestly?"

"Of course."

"Your mom wants me to sleep with her tomorrow night. When the doors close, she thinks that Mark is going to attempt to seduce you."

"Seduce me?"

"Yeah. He confided in her that he wants to fuck you."

"Duh." She smiled. "Who doesn't?" She chuckled.

"Seriously. Your brother wants to fuck you."

"Ok."

"Ok?"

"Yeah. I'll fuck him, but my heart is still with you daddy, and only you can cum in me!"

Tom's cock had grown hard during this exchange with his daughter and her stroking it. But then pulsed when she said that she would fuck her brother."

"You like that daddy?"

"Like what babygirl?"

"You like that I'll let Mark fuck me?"

His cock throbbed again.

"I guess that's a yes."

Tom was silent.

"Why don't you watch him fuck me daddy? You can watch him repeatedly bury his huge cock in your little girl's tight pussy. Mmmm, imagine his thick cock stretching this fuckhole, then you barely feeling the walls of my vagina, after he ruins it for you.

"Oh fuck!"

Tom climbed back onto his daughter, buried his cock in her snug pussy, and released another thick load of semen into her body. That in itself was enough to get Maggie to cum also.

"Oh yes daddy. I'm cumming also! We're cumming together daddy. Fill me with your seed as I cover your cock with my pussy juice! Yesssssssssss!"

After a few moments Tom's flaccid cock slipped out of his daughter's amazing pussy. He watched as his cum oozed from it and still couldn't believe his luck.

He had an amazingly sexy wife, who is now fucking another man (which he loves), he's got an equally amazing daughter who he's now fucking, and it looks like his pussy drought is over.

What more could he ask for?

Morning arrived and Tom slept in. Maggie rose, threw on a light robe and went to make breakfast. Alice decided to sleep in and Mark showered, threw on some sweats and went to grab a cup of coffee. As he approached the kitchen, he saw his sister bent over with her head in the fridge, gathering items to cook for breakfast.

Her short robe was short enough that in this position, her ass and part of her pussy was exposed to anyone behind her. Fortunately for him, Mark was. As he looked, his eyes saw that her sexy pussy lips were parted and his father's semen was leaking from his sister's fuckhole. His cock got hard seeing her pussy, but even harder seeing the proof that their father had fucked her and came inside of her vagina.

"I know what I want for breakfast." Mark teased, as he stared at his sister's exposed pussy. Maggie looked back to see that her brother was looking at her sloppy cunt.

"Eww. It's kinda sloppy right now, bro."

"I don't care. I'll take a taste of that amazing pussy anyway that I can!"

"Stop. Didn't you get enough pussy from mom?"

"Nothing is ever enough." He chuckled. "Yeah, I got lots of pussy from mom, but I wouldn't pass up a chance at yours, for anything!"

"Thanks Mark. But not right now."

"Soon?"

"Maybe." As she resumed making breakfast for the family.

Mark approached his sister from behind and wrapped his arms around her. In doing so, his hard cock pressed against Maggie's ass.

"Mmmm, did I do that?"

"You know you did, sis."

"I know." She giggled.

Mark kissed her neck and she tiled her head back. She was enjoying this. Meanwhile, Alice had awoken and was watching her kids in a sexual embrace and it made her pussy wet.

"She's gonna love his huge cock abusing her little pussy." She thought.

Seeing that Maggie was enjoying his affection, Mark slid a hand into her robe and caressed her breasts.

"Mmmm." Maggie responded.

"God Maggie, your tits are amazing."

"Thanks. You should stop though."

"Yeah Mark. Stop getting your sister all worked up." Alice chimed in from the doorway.

Mark released the grip on his sister's breasts and pulled his hand out of her robe. When he backed away, Alice could see that he was fully erect and that he was excited to be fondling his sister.

"Sorry mom."

"Don't be sorry son. Who couldn't help but fondle such an amazing body when she flaunts it like that." As she smiled at both of them.

"Sorry mom. I'll go put on something more appropriate."

"Don't you dare! You've already teased us with your amazing body, so you can't cover it up now." Alice said as she slipped her hand into her daughter's robe and ran a finger to through the petals of her moist pussy.

Alice removed her finger and brought it to her mouth. "Mmm, delicious, just like I assumed."

"What's delicious, babe?"

All eyes turned to the entrance to the kitchen, to see Tom entering.

"Breakfast is daddy. Please sit." The quick thinking Maggie responded.

Tom surveyed the room and could see that his wife, his daughter, and his son were in extremely close proximity to each other. He noticed that his daughter's robe was still slightly open, exposing her amazing body to her mom and brother.

He also noticed the bulge in Mark's sweats, no doubt from seeing his sister's amazing body exposed to him. All three of them had embarrassed looks upon their faces upon being busted by Tom.

"A little excited this morning, son?" Tom teased Mark.

"Who wouldn't be by seeing your daughter's amazing body?" Alice quipped as she opened Maggie's robe a little more, exposing her entire nude body to both men.

"Mom!" Maggie scolded her mother, as she closed her robe.

"What? It's not like you have anything to be ashamed of. Besides, your dad has already seen you completely naked and who knows, maybe Mark will too."

"MOM!"

"Sorry honey. I guess we'll just have to wait and see what happens."

"Let's eat." Tom said

Maggie passed plates around and as she gave her dad his, she whispered to him "Mark is ok eating my pussy after you've cum in me." Then giggled and walked away.

After seeing the exchange between father and daughter, Alice reached under the table and grasped her husband's fully erect cock through his sweats. She smiled at him, then resumed with breakfast.

That afternoon the family of four decided to spend the day at their private beach. Once there, both women removed their tops and sunbathed all afternoon. No sexual activity occurred, but both men were hard, after being exposed to two beautiful sets of tits all day.

Wine was consumed during dinner and all were feeling giddy and horny. Eventually, Mark went to shower, then to his room, Maggie showered, then went to her's, and the parents went to their room after cleaning up the dining room and locking up.

"I'm gonna shower." Alice spoke.

"Ok."

While Alice showered, Tom slipped out of the room and went to his daughter's room. He walked in and his daughter was dressed in see-through lingerie. Her entire breasts were clearly visible through the diaphanous material of the top. Looking lower, he could see her pussy through the see-through lace of her g-string panties. She was a vision of pure sex!

"Uhmm, what's with the outfit, baby."

Embarrassed by her father questioning her attire, she responded defensively. "Oh, I just figured that if your gonna spend the night with mom, I should make myself feel sexy, since I'll probably be masturbating into the night as I listen to mom orgasm from you giving her some cock."

"Are you sure?"

"Why else would I dress like this, knowing that you won't be coming in here later?"

Tom knew that she was lying. He knew that she was dressed like that as a treat to her bother, who would soon be ravaging her body.

"Ok, baby. Maybe I'll slip out and take care of you, once mom cums and falls asleep."

"NO!" She said almost too quickly. Tom looked at her questionably.

"You should spend the night with her and let me rest, so that I can fuck your brains out tomorrow night."

"Whatever you say, baby." As he smiled knowingly.

Tom left to rejoin his wife. As he entered the room, she spoke to him.

"Giving your daughter a goodnight kiss?"

"Uh, Uh..."

"It's ok babe. You're mine tonight. Tomorrow, you can slide this daddy dick back into your horny daughter."

She too had dressed in a sexy outfit. She wore a white mesh babydoll, tied with a satin sash. It was completely see-through and her large, dark areola were visible. Her erect nipples already protruded, creating lumps at the end of each breast. Below that she wore matching (mesh) g-string panties. Her pubic hair landing strip was also visible, just above her swelling clit hood. (She had masturbated in the bath, as she readied herself for the fuckfest that she was anticipating this evening).

The extended pussy lips of her sex were slightly spread and Tom could see the distinct moisture within her petals. Maggie definitely got her sex appeal, beauty, and amazing body, from her mother.

Tom approached, then wrapped his arms around his wife.

"I've missed you." He said.

"I've missed you too."

"Yeah, but you loved fucking our son, didn't you."

"Obviously. But I was soooo horny and needed cock. It had been so long since I've had this in me" as she reached down and grasped his hard cock. "And I really needed to get fucked."

"Mark was patient and took his time seducing me. The first time that I saw his cock, I was so horny and desperate for sex, that the sight of his huge cock had my pussy gushing."

"You wanted to fuck him immediately?"

"No. I didn't want to be unfaithful to you. I was just extremely aroused, but had no intention of allowing any sexual activity to happen between us."

"Tell me about the first time that you crossed that line." Tom asked.

"It actually happened when I caught the kids naked in the tub, playing truth or dare. I joined the game and soon they found out about some personal stuff about me."

"Like what?"

"It doesn't matter. But at one point Mark chose dare and Maggie told him to stand and jack off for 5 minutes. He stood and it was then that we realized that he was nude. His cock is huge! Definitely the biggest that I've ever seen. After 5 minutes he sat down and Maggie left for bed."

"He decided to call it a night and stood to leave also. I don't know why, but I was so enthralled with the sight of his huge cock (still fully erect), that I reached out and touched it. One thing led to another and I jacked him off until he came."

"Afterwards I felt guilty and had a talk with him. I told him that it would never happen again, but the seed had already been planted in his mind and he set out to seduce me."

"Another time, I jacked him off again and allowed him to see my breasts. From there it escalated to him finger fucking me and me giving him head. It was kinda weird having my son's cock in my mouth, while his hands ran through my hair."

"Did he cum in your mouth?"

"Oh yeah!"

"Oh yeah?"

"Yeah, he came a lot and I swallowed his entire load. Eventually, I let him eat my pussy and came from it. As you saw, he eventually fucked me. His cock is so thick that it felt amazing stretching out his mother's fuckhole."

Unable to control himself any longer, Tom removed his wife's babydoll and panties, then removed his clothes. Once they were both naked, Tom spread her legs and looked at his wife's dilated pussy. Her entrance had not yet returned to it's normally closed state and he could tell that his son's huge cock had stretched her pussy, without it retracting completely.

Tom loved the sight of seeing his wife's vaginal entrance open and the pink inner vaginal canal plainly visible. He slid his fingers between the petals of her pussy, feeling the moisture in every crevice of the pussy that once belonged to only him. He knew then that he would be sharing his wife's pussy with their son from now on.

"Would he soon be sharing his daughter Maggie's pussy with Mark also?" He wondered.

Tom began exploring every nook and cranny of his wife's shared pussy with his mouth, fingers, and tongue. Although she had bathed, he could taste the faint flavor of his son's semen, that Mark had pumped deep into her vagina the previous night and early that morning. Tom was hard as stone at the taste and thought of his wife's unfaithful pussy having been filled with his son's cum..

Meanwhile, having seen his parent's door closed, Mark moved down the hall to his sister's door. He tapped lightly, but got no response. Another tap got no response either. Slowly and quietly he opened her door.

Maggie (still in her lingerie) was lying back in her bed. Her eyes were focused on a picture in her hand, while her other hand slid a life-like replica cock in and out of her soaking wet pussy. Mark figured out that the picture was that of their father's cock and the life-like rubber phallus was a replica of Tom's cock.

"You miss his cock already?" Mark whispered to his sister.

Maggie looked at her brother and gasped.

"What the fuck Mark, what are you doing in here?" As she pretended to not know why he had invaded her privacy. Then she pulled the fake cock from her depths and tried to cover up.

"Don't be shy Mags, I've already seen your amazing pussy. Let me look."

"No. You shouldn't be in here."

"Why not? We're both horny and our parents are satisfying each other's needs, so why shouldn't we."

"Because Mark. You're my brother! We shouldn't cross that line."

"Hold on! You've been fucking dad and you know that I've been fucking mom, so if we're already committing incest with our parents, why should we be fucking also?"

"Like you said, you're already fucking mom and dad and I are already having sexual intercourse, so we should leave it at that."

Mark sat in the edge of the bed and let his robe fall open. He was naked below and his hard cock stuck out of his robe. Maggie continued to try and cover up her nearly naked body, but not doing a very good job of it. Mark rubbed her leg to try and comfort her and Maggie didn't say or do anything about it. As he caressed her leg, he tried to seduce his older sister.

"Look. I know that you miss dad right now and I'm sure that you're jealous that he's giving mom his cock. But you have needs and I can help. As he spoke his hand traveled up her thigh.

"Let me help you, sis."

His hand reached her pussy and he caressed her pussy lips.

"No." She stopped him. Her hand removed his from her pussy. He grasped her hand and brought it to his cock.

"Holy fuck Mark! You're fucking hard!"

"You did that."

"How?"

"Seeing you in this sexy lingerie, then watching you fuck yourself with the fake cock brought it on. Your pussy is beautiful."

"Thanks."

Maggie didn't realize that during this exchange, her hand never left her brother's cock. Mark removed his hand and once again caressed her inner thigh.

"Fuck Mark, your cock is huge. Didn't it hurt mom the first time you fucked her?"

"Nah. Her pussy accepted it and she enjoyed how it felt inside of her."

"I'll bet." She said bashfully.

"Do you like it."

"Of course."

"Good, cus I like your pussy."

Maggie hadn't realized that Mark was caressing her pussy again. His fingers once again slid between the petals of her moist pussy. He stroked her lips without penetrating her pussy until after a slight upward motion, the tips of his fingers grazed her clit.

"Mmmm. Fuck that feels good." She moaned.

"Your pussy is amazing sis."

"More amazing than mom's" she asked, not deterring his advances.

"Yeah."

"How so?"

"Your pussy gets more moist. Your vaginal secretions are more gel-like than mom's. Her moisture is a little less dense than your's whereas your moisture is thicker and mucus-like. I'll bet it tastes amazing also.

"Maybe." Maggie teased.

Mark removed his fingers and brought them to his mouth. He first smelled the vaginal fluid, then parted his lips and tasted his sister's pussy juice for the first time.

"Oh my God, you smell and taste delicious."

"Thanks."

Meanwhile, her hand had begun seriously stroking her younger brother's huge cock. She looked in his eyes, then back at his cock. When she saw precum ooze from his pee-hole, she decided that turnabout was fair game. Slowly, she bore her eyes into his, as she lowered her head to his crotch, opened her mouth, and licked the pre-ejaculate fluid from the tip of her brother's massive cock. Then she pulled away.

"Holy fuck, Mags! Suck my cock."

"I can't. I just wanted to return the favor."

"Favor?"

"Yeah. Having you taste my pussy was such a turn on, that I figured that you'd like it, if I tasted your pre-cum. No more. This pussy now belongs to daddy. Now go."

Mark rose and left, feeling dejected. As he closed his sister's door, he heard his mother's voice in the throes of an orgasm. He listened for a few moments, then walked back to his room, closed the door, and began masturbating.

Meanwhile, behind his parent's door...

"Oh fuck babe, I love when you eat my kitty. How do I taste?"

"Delicious. A little different, but still delicious."

"Different?"

Tom was embarrassingly quiet and kept eating her pussy, occasionally plunging his tongue deep into his wife's vagina and still being able to taste the remnants of his son's seed. Tom, being 100% straight was confused by the excitement he received from knowing that the taste of his wife's pussy had a hint of flavor that he knew to be that of his son's cum.

"Can you still taste Mark's cum in my pussy babe?"

"Just slightly?"

"Does it excite you to know that some of our son's cum is still deep inside of your wife's vagina?"

"It's not like I'm actually eating his cum, but there definitely is a distinct flavor that is not all yours."

"Do you like it?"

"Well, your pussy always tastes amazing. The flavor is definitely different now. I mean, I could taste the remnants of his cum combined with your flavor and it still tastes good."

"Would you want to eat my pussy right after Mark pumps load after load of his thick seed inside of me? You know, basically eat a cum filled creampie?"

"Definitely not! You know that I'm 100% straight and have zero gay intentions. To me, eating another guy's cum has gay tendencies and I'm not into that. I don't mind eating your amazing pussy after he's fucked you, but only after you washed out any lingering cum from it. I do love seeing your pussy overflowing with thick seed and watching his cum ooze from your pussy, but I definitely don't want to taste it."

"He doesn't mind."

"What?"

"Yeah. He said that he doesn't mind eating a cream pie. Who knows, he might be eating your cream pie out of Maggie's pussy right now."

"Fuck, I'd love to see the two of them together."

"I'm sure it'll happen."

Across the hall, the thought of her parents having sex turned Maggie on.

"Fuck this. I wanna hear them." She thought.

Quietly she rose, left her room, and crept to her parent's door. She heard her parents talking while having sex and overheard her mother teasing her father about Mark eating his come out of her pussy. Her pussy was soaked and her hand slid down to masturbate to her parents having sex.

Suddenly she felt Mark behind her. As she readied to stop him his hand covered hers. His cock, now pressed against her backside, made her lightly moan.

"Mmmm."

She could feel his extremely hard erection wedged between her butt cheeks and it felt good. As she was about to stop him, Mark whispered.

"Shhhh. Just relax and enjoy this."

She did, once she realized that her baby brother's fingers had found a way past her hand and was pleasuring her clit. Mark was good and showed his skills to his older sister, as he massaged her clit, then slid between the folds of her extremely stimulated pussy. Mark kissed her neck as she fell deeper into euphoria.

Eventually, he grasped her chin with his other hand and guided her mouth to his. Once there, he kissed her lips, then licked them. Soon her mouth opened and his tongue entered her mouth. On the verge of an orgasm, she allowed him to French kiss her, eventually returning the gesture. The siblings listened to their parents having sex as they kissed passionately.

Realizing that Maggie's defenses were now down, Mark swooped her up into his arms and carried her back to her room. There he laid her on her back and moved between her outstretched legs. He moved the gusset of her lace panties to one side and lowered his mouth to her pussy.

Maggie was now in heaven as her baby brother ate her pussy. Minutes later her hands were weaved into her brother's hair and her hips rose to drive him into her pleasure dome. Her climax was intense as she came from the oral sex that Mark was performing on her.

"Oh fuck Mark. That's it baby. I'm cumming. Oh, Oh, Oh, yesssss!"

As her body slowed from shivering, she realized that she wanted more. As she lay there Mark slid up her body to suck and nibble on her breasts (through her babydoll). Wanting to feel his amazing mouth on her bare skin, she pushed him back, lifted the lingerie from her body and threw it on the floor, then pulled her brother back to her breasts.

"God, I love your boobs, Mags."

"Show me."

And he did. Spending plenty of time manipulating them, sucking them, and worshipping them. Maggie was in a constant state of arousal as her brother continued with the tit-play.

Eventually, Mark slid further up her body and begin kissing her again. His athletic body lay between his sister's outstretched legs and his hard cock rested on her mons. After passionately kissing his sister for a while, Mark wanted more. He slid his body down, so that his cock fell between Maggie's legs. His cock was now poised to penetrate her pussy, the dome just below her heavenly vaginal gates.

Mark grasped his sister's face again and stared at her. Sensing that Mark was looking at her, she opened her eyes. Now the siblings looked deep into each other's eyes as Mark moved his hips forward and the tip of his rigid cock spread the lips of her amazing pussy. Not getting any resistance from her or her telling him to stop, he pushed forward and the head of his cock penetrated his sister pussy.

Maggie closed her eyes in a sign of pleasure and Mark pushed more of his massive cock into her. Now with 3" inches of solid cock lodged in her vagina, Maggie moaned again.

"Fuckkkkkk."

"Right?!" Mark responded then pushed another 3" inches of cock into his sister's fuckhole.

Her vaginal canal was now almost full of his massive cock and it felt amazing to both of them. Slowly Mark withdrew a majority of his cock and Maggie worried that he was pulling out. Instinctively, her legs wrapped around his waist and pulled him back in. Mark smiled at her, then retracted again. Once again, Maggie used her legs to pull his cock back in.

They established a little game of back and forth until Mark plunged more cock into her vagina, filling her completely.

"Oh fuck yeah, Mark! Fuck me!"

"With pleasure." As he began fucking his sister in earnest.

Maggie began moaning constantly and more loudly than normal as her brother fucked the shit out of her. They fucked for around 15 minutes, until Maggie wanted to change positions.

"Let me ride you, bro."

"Ok."

Mark withdrew, lay back and Maggie straddled his body. She rose above his cock then gripped it and lined it up to her vaginal entrance. Slowly, she lowered herself until her vagina was full of cock.

"Mmmm." She moaned then began riding her brother's cock.

Once again she began moaning loudly and talking dirty to her brother.

""Oh Mark. I love the feel of your huge cock in my little kitty, babe. Mmmm. Oh yeah! Oh, umm, umm, umm."

Across the hall, Tom had fucked his wife through 3 orgasms. Her climaxes were intense and she finished him off in her mouth, then he passed out. As planned, once Alice knew that Tom was asleep, she quietly and carefully slid from the bed and slipped out the door, completely naked.

Tom, knowing this would happen, faked sleep and watched his nude wife leave their room. Alice entered her daughter's room and was treated to the vision of her daughter's stretched pussy, wrapped around her son's huge cock as she rode her brother.

"I'm gonna cum again, Mark."

"I'm not too far behind you, Mags."

"Ok, but don't cum in me."

"Aren't you on the pill?"

Maggie stopped moving and looked hard at her brother.

"Don't cum in me!"

"Ok."

Alice walked to the head of the bed and straddled her son's face, then kissed her daughter while reaching out and playing with her tits. Their kiss became passionate and Mark witnessed his mom's and sister's tongues going back and forth in a passionate battle.

Tom quietly slid into the room and witnessed the sexual activity of his family. He wanted in but didn't know where to join.

"Should I get behind my wife and slip my cock into her pussy again? Should I let the two ladies pleasure me with their mouths (jointly)? Should I slide between Mark's and Maggie's legs and eat her ass, while Mark gives her his hard cock?" Tom contemplated.

Finally, he decided what to do. Just as quietly as he entered the room, he slid back out and down the hall to his and his wife's room. There he found a bottle of KY lotion, then went back to Maggie's room. He had previously thought about anal sex with her, and now was the perfect opportunity.

Once at the foot of the bed, Mark had slid his body to the edge and Maggie's ass was in perfect position for Tom to attempt penetrating it with his cock. Tom coated his cock with the lotion, but as he looked at his son's cock sliding in and out of his little girl's pussy, something clicked in his mind.

He then lowered his face to her ass and began licking around her anus. This brought Maggie deeper into euphoria and she spoke.

"Oh fuck that feels good! Lower daddy."

Tom, wanting to please his daughter began licking her perineum.

"Oh yessss, daddy! Lower please!"

Tom slid further down and his tongue touched the bottom edge of her pussy and brought her over the edge.

"Oh yessss daddy. Right there. I'm gonna cum. Ohhhhhhh Yeahhhhh. I'mmmmmm cummmmminggggg!"

Maggie's pussy squirted for the first time ever and climax was the most intense that she ever had. In the throes of her orgasm, Tom's tongue slid into her pussy, right up against Mark's cock! Tom could taste his little girl's vaginal fluid on his son's shaft and it brought him close to cumming himself. But realizing that his tongue had touched his son's cock, he quickly pulled away.

Now he knew what he had to do. He poured KY lotion in the crack of Maggie's tight little ass, lined up his extremely stiff cock to her anus, and pushed in. As the crown of the bulbous head of his cock popped through her nether hole, Maggie realized what her father was doing.

"Daddy?" She exclaimed in a frantic tone.

"Relax baby."

"Yeah baby, relax. You're gonna love this." Came the encouraging voice of her mother.

Maggie relaxed and Tom proceeded to push more of his cock into his little girl's virgin ass. Slowly he pushed in and out burying more and more of his cock into his daughter's asshole, all the while feeling the hard shaft of his son's cock through the thin membrane of skin between her ass and pussy.

By the time that he bottomed out, Maggie's anus had become accustomed to it. Her ass was tight, but slowly opened to accept her father's cock. Mark felt his father's cock through the thin membrane separating Maggie's vagina from her asshole and it almost made him cum.

"Oh my God, that's feels amazing!" Maggie screamed.

"I know. I won't last long guys." Mark exclaimed.

"Don't you dare cum in me Mark!"

Tom was baffled by that comment. He had cum in her multiple times already and just like seeing his wife's pussy oozing thick semen, Tom was hoping to see Mark fill his sister's vagina with his seed.

"I'm close Mags!"

With that, Maggie lifted off of his cock, slid down his body, with her dad's cock still embedded in her asshole and began sucking her brother's cock. Alice joined her daughter and the two women sucked and stroked Mark's cock until he came. Simultaneously both women came also, causing Tom to dump his load deep into his daughter's bowels.

With sweat glistening on each naked body and cum oozing from Maggie's asshole, all four rested.

Tom woke, a little disoriented. He realized that he was still naked, lying in his daughter's bed. Sleeping next to him was his wife of 20 years. She too was nude, but her pussy showed no sign that their son's huge cock had wrecked it on the previous night. They were alone. Their son and daughter were nowhere to be seen.

In the distance, he heard the obvious sound of sex. Instinctively, he rose and followed the sound until he was just outside of his son's bedroom. The door was slightly ajar and he heard his daughter's sexual banter.

"Oh God Mark, your cock feels so good in me. We should've done this a long time ago."

"Well I plan on making up for lost time and fucking you as often as you'll let me."

"Mark, I love your cock and the sex is amazing, but this pussy belongs to daddy now. His cock feels amazing also, but there's more to it."

"How so?"

"Sex with dad is amazing also, but being in love with him adds an element that can't be topped by just amazing sex. Dad and I make love and the feeling deep within my soul is untouchable by anyone. You're an amazing fuck Mark and if it's ok with dad, I'll fuck you occasionally, but keep in mind that this pussy, this body, this soul, belongs to daddy."

"I'll take whatever sex you'll allow me to have, Mags."

"Just promise me that you'll never cum in me until I tell you that it's ok."

"Ok. I promise." Then he began fucking her in earnest.

Tom watched as his son's glistening cock slid in and out of his baby girl's tight pussy, covered in her vaginal fluid. Her pussy lips gripped the huge shaft and could be seen going in and out as they held on to the thick shaft of cock.

"That's it Mark, fuck this pussy. You like my pussy, don't you."

"I love this pussy."

"I'll bet you wanna pump load after load of your cum deep inside of me, don't you?"

"Oh fuck! You know I do! Don't tease me. You're gonna make me cum."

"Oh fuck! I'm cumming bro! Oh! Oh! Oh! YESSSSSSSSS. I'm cumming."

"Me too!"

"Nooooooo!"

Mark pulled out just as his cock throbbed and he shot his entire load on his sister's tight abs. Fortunately, none of his potent semen had ejaculated within her tight pussy. Spurt after spurt of his cum shot onto her body covering her stomach and her large breasts with his entire load.

Outside the door, Tom was stroking his cock while watching his offspring have unbridled sex. Suddenly, he felt a nude body press against his from behind. A hand reached around and grasped his cock. Kisses were placed on his neck as the soft hand stroked his extremely hard erection. He closed his eyes and enjoyed the soft touch on his cock.

Then he heard the sound of his wife in the distance.

"Babe. Can you bring me a glass of water. I've got a splitting headache."

His eyes shot open in shock as he realized that the woman behind him, stroking his cock, was not his wife.
