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

Carl and Claire had been empty nesters for over 15 years. Their twins had married amazing spouses and life was good.

April and Mark have no children and live around 3 hours away. Mark is a member of the National Guard and is required to spend one weekend a month deployed throughout the state. When deployed, April spends those weekends at her parents and they are happy that she still visits.

April and Mark's sex life is strong and they are secure enough to talk about just about everything (including men flirting with and trying to bed April). Mark sometimes teases her that with his work schedule, she should take on a fuck buddy, but she refuses.

"Is he serious or just messing with me?" She'd wonder. "there's no way I could fuck anyone but Mark. It could get too complicated." She thought.

They sometimes role-play about swinging and they both enjoy the orgasms that they share, but both are too scared to actually fuck others. April was a virgin and never acted on those advances from others, so Mark has been her only lover. Mark had a few partners before April, but doesn't like to talk about them.

Like April, Fran was also a virgin before CJ deflowered her. Although she had never been fucked, she did have a sexual relationship with her father, but doesn't talk about it. Her father was very similar to her father in law, so there was some attraction to Carl, but she would never discuss it with CJ or act on it. Like Mark, CJ had a few lovers before Fran.

After a night of role-play passion, Mark questioned April.

"Hun, I was thinking..."

"Yeah, about what?"

"Tomorrow, instead of going to your parent's for the weekend, maybe you should stay home."

"Ummm, why?"

"Well, you really seem to love role-playing about another man fucking you, so maybe you should try to find someone to actually fuck you."

"Babe, the role-play is amazing and the fantasy of fucking another guy really gets me off. But I can't actually do it."

"Why not?"

"First of all, I'm not gonna cheat on you!"

"It's not cheating if I want you to do it."

"Also, I can't just fuck some stranger and I'm definitely not fucking someone that we know, so it won't happen."

"Just consider it, ok?"

"Ok Babe, I'll consider it, but it won't happen."

Upon his return, Mark decided to try a plan to get his wife to fuck another guy. He made every excuse possible to keep from fucking his wife for the entire month. April masturbated frequently, but it just wasn't enough. Friday morning (before he was set to leave again) he once again mentioned that she should stay home and find someone to fuck her. This time, she wasn't as adamant about not doing it.

"Look babe, I know that you purposely held out sex from me this month. So I'm convinced that you really want me to fuck another guy and it's not just a fantasy for you. But it's not gonna happen this weekend. I've already got plans with my parents and can't back out, but I'm now really considering going for it, in the future. Are you really sure that you want this? Because if the opportunity does arise, I'm so horny that I may go through with it."

"Hun, I'm 100% sure that I want this to happen. All that I ask is that, if you do fuck another guy, you tell me all about it."

"Ok."

Once he left, April packed for her trip to her parent's house. She arrived late

afternoon and had dinner with them. As night approached they decided to watch a movie in the family room. All three retired to their respective rooms to change into night attire and get comfortable for the long movie.

Carl wore sweats and a wife beater, Claire wore a knee high cotton nightgown, and April chose a thigh-high night shirt. None of them wore anything revealing or sexy. After all it was an adult woman and her parents preparing to watch a movie. About 45 minutes into the movie, Claire had tired of dozing off only to be awoken by Carl to continue watching the movie. So she excused herself and went to bed.

Carl and April continued to watch the movie and when it ended, Carl noticed that April had fallen asleep on the couch. Needing to use the restroom, he quietly got up and went to urinate. Upon his return, he stopped dead in his tracks. April had moved and her legs were now spread slightly apart. Her nightshirt had ridden up and there before him was his daughter's panties. April loved the look and feel of lace panties and the ones that she had on were very see-through.

Carl could now see his daughter's pubic hair, manicured in a landing strip on her mons. As he looked closer he could see that her pubic hair ended just above her clit hood and he could tell that she must be completely smooth below. Her vaginal opening was covered by the gusset of her panties, but Carl just knew that her pussy must be smooth and moist at that very moment.

His cock hardened immediately as he saw his daughter's pussy for the first time. Although she was an attractive teen and an even more sexy woman, he had never thought of her sexually, but now he was seeing her as such. He moved closer to get a better look at his daughter's covered pussy. He stood less than five feet from her staring at her barely covered pussy, through her see-through panties and could now see her moist pussy lips.

They were moist because unbeknownst to him, April had woken up and when she did, she saw that her father was staring below the upturned nightshirt and that he had an unobstructed view of his daughter's barely covered pussy.

What she also noticed was the very prominent bulge in her father's sweats. The sweats were tight enough that she could see every detail of her father's cock, through his sweats. He was hard because of her and since she hadn't been laid in over a month, it made her pussy moisten at the thought of her dad seeing her pussy and the prominent bulge in his sweats.

"Oh my God, did I cause that?" She wondered. "He's huge!"

Growing up, she had often had fantasies about her father. Like many girls, she had fallen in love with her father and had hoped that he would deflower her, but he never did. She spent many nights masturbating to the thought of her father fucking her. She even wondered what his cock looked like and now she had an idea. As she reminisced, she unknowingly spread her legs further apart.

"Mmmm" was a slight moan that she heard from her father as her crotch was more exposed to him.

Just then she looked at his face and their eyes met. Instinctively she closed her legs and pulled the hem down to cover her privates. She had a concerned look on her face.

"Babygirl, I'm so sorry." He said. "I walked in here and... I...

I... didn't mean to look. You were just there."

"But dad, you continued to look." She said with concern.

"I know. And I'm sorry. You see, it's been a while since I've seen a woman like that and as I walked in, I saw you and couldn't look away."

"You don't see mom?"

"I do occasionally, but not that often and ..."

"And what dad?"

"Nothing. Never mind."

"No dad. Tell me."

"I can't."

"Why not?"

"I just can't."

"Dad. You need to explain!"

"Ok, well... your mom and I aren't intimate anymore and to be honest, I'm easily aroused."

"So you're saying that your obvious arousal (as she looked at the obvious erection in his sweats) isn't because you find the sight of my privates arousing or exciting, but because anybody would arouse you?"

"No! I'm sorry if it sounds like that. Please don't be upset for me saying this, but trust me, you're extremely sexy."

"Thanks daddy" she said almost seductively. "Why don't you two have sex anymore?"

"The older she got, her urge has died down. Besides, her natural lubricants don't flow like they use to."

"Have you tried KY?"

"Yeah, but it's just not as natural. Besides... never mind."

"Besides what, dad?

"No. Forget it."

She reached out and grasped her father's hand. "Dad. Please tell me."

"Ok. But it's very embarrassing to talk about this."

"Dad, we're both adults. It's ok to discuss these things. Especially if I may be able to help you."

"Help me?" He raised a brow.

"No. Not like that, daddy. I mean figure out a solution to your problem."

"Ok, well it's just that I'm... I'm...

I'm kinda big (if you know what I mean) and it's not as comfortable for her anymore."

April smiled seductively "Kinda?" She giggled "I noticed." She responded with a smile, as she looked down at his crotch again.

Carl looked at the bulge and apologized. "I'm sorry."

"There's absolutely nothing for you to be sorry about, daddy." She grinned and said seductively.

"Daddy? Holy fuck that's sexy!" Carl thought

"We should head to bed now daddy." Again seductively.

Carl's eyes got big.

"Our own beds, daddy." She smiled and walked away seductively, swaying her ass just slightly.

As she lay in bed, she thought about all that transpired that night. Naturally, her hand slid into her panties and her fingers slid between her labia. It was then that she noticed that her pussy was soaking wet. Then it dawned on her. Immediately she jumped up and walked to the full length mirror on the door. She looked down and saw that the gusset of her panties was completely soaked through with her vaginal secretions.

"Holy fuck! He saw that." As she realized that her father had actually seen her pussy juice soaking through her panties and that's probably why his cock was so hard. Just then the vision of her father's covered cock flooded her mind. She thought back to seeing his cock through his sweats and her pussy moistened even more. Slowly she got back into bed and masturbated to the thought of her father's large cock finally penetrating her pussy and giving her the fucking that she (so desperately) needed.

Nothing was mentioned the next day and the three of them spent time together at the farmers market. Upon returning home, April's phone rang.

"Hey babe, what's up?"

"Nothing too much. Just going through routines. Find any one to fuck yet?"

"Actually..."

"Really?" Mike asked excitedly.

"I'm just kidding."

"Fuck hun, you got me all excited."

"Well, I do have a little story to tell you about an incident that happened."

"Really? Please tell me."

"Well, last night my parents and I got comfortable in our night attire and watched a movie."

"Borrrrrrring."

"Shut up, silly."

"Ok, go on."

"Mom got tired and went to bed leaving dad and me to finish the movie."

"Mmhmm, go on."

"By the end of the movie, I was getting super tired. I did drive all the way out here, you know."

"Go on."

"Dad got up and went to use the restroom. I was tired and started dozing off. Upon his return I opened my eyes and saw that he was looking at my lower body. I then realized that as I lay on the couch, my legs had opened up slightly and my nightshirt had ridden up. My father had an unobstructed view of my see-through lace panties."

"I really couldn't blame him for looking. I'm sure he had no intention of checking me out, but when you're a grown man, haven't had sex in a while, and a female's intimate undergarment is exposed, it's only natural to look and maybe even imagine what's below the thin material of those panties."

"Hold on. How do you know that he hasn't had sex in a while?"

"Let me finish."

"Ok."

"Then he moved closer. I guess to get a better look at my pussy. As he approached the couch, I couldn't help but notice a significant bulge in his pants. I was shocked but flattered to see that my father got an erection from looking at his own daughter's private area. He looked at my face and realized that I had woken up and had caught him looking. He apologized, but then (after I made him tell me) he revealed that him and mom don't have sex anymore. He said that she doesn't get wet enough and with his "size" it's become uncomfortable for her. So they stopped having sex. Basically, he's extremely horny and needs sexual relief."

"His size?"

"Yeah. I didn't actually see his cock, but from what I could tell from the bulge in his sweats, it's huge. Besides, he admitted that with his size, sex has become uncomfortable for my mom."

"So when are you gonna fuck him?" Mike chuckled.

"Stop it! I'm not! I just wanted to be honest and tell you what transpired. Nothing more will happen with my dad."

"I'm just saying that you're horny, he's horny, and I'm completely ok with you fucking your dad."

"It's never gonna happen."

"Never say never!" Then he chuckled.

Later that night, April and her parents changed into night attire and settled in to watch another movie. Like the previous night, after a while, Claire excused herself to bed again, leaving April and Carl to finish the movie. But as she was leaving the room, April saw that her mom had looked back at her father and smiled.

"Does she know?" April thought. "Is she ok with my father seducing and fucking me?" She wondered.

Periodically, throughout the night, April could see that her dad kept glancing at her exposed legs and every so often, would discreetly "adjust" himself. April once again, felt that her pussy had moistened, but knew that she couldn't continue with this dangerous game.

After the movie ended, Carl once again got up and went to urinate. He quietly returned and April could tell that he was hoping that maybe she fell asleep again and he'd be treated to the vision of his daughter's see-through panties.

April couldn't allow it to happen again, so she stayed awake. Upon his return, Carl sat on the recliner directly across from his daughter and continued to glance at her legs (and the hem of her nightshirt that covered his little girl's precious pussy).

Eventually, April decided to go to bed. As she rose from the couch, her nightshirt slid up her legs and Carl was treated to a quick flash of his daughter's panties. April looked to see that her father's erection was back and completely showing through his sweats. Her pussy moistened and thoughts of letting her father fuck her, once again filled her head. But she wasn't going to do it.

Once again, April masturbated to thoughts of her father fucking her. In the heat of her self induced orgasm she actually spoke to him in a seductive whisper.

"Oh fuck daddy. I'm gonna cum. Yessssssss. Right there daddy. Oh yeah, Fuck me." She tried to whisper in the midst of her approaching orgasm.

Unbeknownst to her, her mother had been walking towards the kitchen and could hear her daughter fantasizing and getting ready to orgasm, to the thought of her own father (Claire's husband) satisfying his daughter's sexual needs. It was then that Claire vowed to allow and even encourage the two to commit incest and fulfill each other's sexual needs. She had an idea and went back to her room.

Upon returning to her bed, Claire looked upon her husband's in deep sleep. She quietly got into bed and woke her husband.

"Babe... babe..."

"Wha... what's up?"

"Babe, I've got a splitting headache. Can you go and get me some Tylenol and a glass of water?"

"Ummm, ok."

Carl rose and exited their room. Immediately, Claire rose to see if her husband could hear their daughter masturbating. She approached the door and realized that Carl had left it slightly ajar. Quietly she moved to the opening and peered into the darkened hallway. As she had hoped, her husband was stopped in front of the door to their daughter's room and it was evident that he was trying to hear what was going on behind the closed door.

"Mmmm." Carl quietly moaned as he listened. He moved closer to the door and pressed his ear to it. Claire watched as her husband reached down and began caressing the noticeable bulge in his sweats. Eventually, Carl released his fully erect cock and began stroking himself in the hallway, as he listened to his daughter pleasuring herself to the thought of her father fucking her.

"That's it babygirl, cum for daddy." He quietly whispered while he stroked his cock.

After a few moments, the realization that he had been taking too long to retrieve the meds for his wife sunk in and he continued down the hall. But not before first whispering...

"One day I'm gonna get this cock into your tight little pussy babygirl and you won't have to fantasize any more!"

Carl continued to the kitchen and Claire retreated back to bed. Upon his return, he handed his wife the meds and water. She downed it quickly then turned away from her husband and pretended to want to sleep. In doing so, her nightgown rose, exposing her completely uncovered ass and pussy. She had removed her panties and had hoped to arouse her husband with the view of her sex.

It worked. Carl stared at his wife's exposed fuckhole and her delicate asshole and became fully erect again. He noticed that for the first time (in a long time) his wife's vagina looked to be extremely moist. He slid into bed and spooned his wife, hoping to arouse her enough to fuck him, but that was not to be. Soon they both fell asleep, completely frustrated and unsatisfied.

The following day would be their final day & night together, as April was going to return home early Monday morning. As usual, Claire planned to go to church early. April woke just before her mother left and greeted her in the kitchen, wearing the same nightshirt, without bother to put a robe on.

"Sleep well darling?" Claire said, almost in a knowing tone.

"Ok, I guess."

"Just ok?

"Yeah, I'm a little restless and miss Mike."

"Well you'll both be back home tomorrow, so things should get better then."

"I hope so." April said disappointedly.

"Your father is showering now, so you may as well get ready for the day. I'll be back in a couple of hours." Then she left. April watched her mother drive away and decided to take a peek into her parent's bathroom, in hopes of catching a glimpse of her showering father.

She stood at the door to the master bedroom and could hear that her father was still showering. Quietly she opened the door and could see her nude father showering in the adjacent bath suite. As she crept into the room, she heard her father's voice.

"That's it babygirl. Stroke your daddy's cock. You want it, don't you?"

"Yes, I do." April thought as she looked to see her father (with his eyes closed) stroking his cock.

Her eyes widened as she saw her father's bare cock for the first time. His cock was (indeed) extremely large. It was at least 3 inches longer than her husband's and almost twice as thick! As the water rinsed the soap suds from it, April could see the thick veins protruding from it and its slight upward curve.

"Holy fuck!" She thought. "No wonder it's uncomfortable for mom to take that monster into her. But his cock must feel amazing deep within her fuckhole, as that curve helps it to hit her G spot!

"Oh baby, your pussy is so tight. I love it. Your husband will definitely be able to tell that his wife's pussy has had another cock in it, when he returns home. Oh baby, daddy is gonna cum in you now."

"Yes, daddy. Mike is definitely gonna know that this pussy was ruined by your huge cock. Now, cum for me daddy. Pretend like you're cumming deep inside your little girl's unfaithful cunt!" April whispered.

He did. Carl came hard. April watched spurt as spurt of her father's semen plastered the shower glass. She was extremely turned on seeing his her father's huge cock pulse as his thick cum exploded onto the glass and almost came herself. Two of her fingers were sliding in and out of her drenched fuckhole while she caressed her clit with the other.

It was then that she realized that she wanted to fulfill her husband's request to have another man fuck her. Not just any man though. She wanted her very own father to be that man and wanted to feel his cock pulse, deep within her as he filled her vagina with his seed. She also wanted to try and swallow that huge load, to taste her father's cum as she sucked his cock.

After realizing that her father could see her, if he were to open his eyes and look towards her, she retreaded from the room and closed the door. Carl had thought that he heard the door close, but couldn't be sure.

"God, did she watch me jack off?" He thought. He finished his shower, then dressed for the day. Afterwards, he heard April showering and was tempted to peek at her, but decided against it. He already knew that she had masturbated while thinking about him fucking her. Now it was just a matter of time before he actually fucked her. It was a new and exciting goal, that he planned to accomplish!
