Over the past week, Alice had masturbated her son Mark’s cock twice (until he came) and she allowed him to fondle and suck on her breasts once.
After each encounter, she was riddled with guilt and vowed to not let these encounters continue.
Maggie (on the other hand) had not been as successful at crossing over the incestuous line with her father. Tom had seen his daughter’s unobstructed, bare pussy and young breasts a few times and she had seen his bare cock once, but they never engaged in any sexual activity (although they did have conversations about sex and sexual relations).
Thursday night, before going to bed, Maggie decided to treat her father to an early morning surprise on Friday morning. She masturbated with her father’s replica dildo and left it on the nightstand, along with the picture of his cock. Then she went to sleep completely naked with her pussy dripping her very own vaginal fluid.
As usual, Tom went to wake his daughter in the wee hours of the morning. As he entered the room, her nightlight illuminated her glistening body to his eyes. He stared at her entire body, then focused on her extremely moist vagina. As he stepped closer, he could see that the entrance to her pussy was dilated from the abuse that she punished herself with, using the replica dildo of her father’s cock.
Tom saw the dildo and picture on the nightstand and was shocked to find out that his daughter was using the replica of his cock to masturbate to. But it also confirmed to him, that his daughter wanted to fuck him.
Maggie woke and saw her father staring at her naked body.
“Good morning Daddy. Time to leave yet?”
“Almost babygirl. Get ready quickly. It’s our last day of fishing this week.”
“Ok daddy.” Maggie rose without covering her nude body and her father watched her as she prepared for the day. No words were spoken, but it was obvious that her nudity in front of her father, didn’t bother either of them. Maggie saw the exaggerated bulge in her dad’s shorts and knew that seeing her nude body was having the desired effect on him. After taking in the amazing view of his daughter’s perfect body, Tom left to prepare breakfast for the two of them.
As usual, they ate quickly, then left for the day.
Alice woke and guilt was once again front and center in her mind. She knew that her lack of sex over the past 10 years has had her extremely horny and needy, but still couldn’t understand what led her to touch (let alone jack off) her own son’s cock twice and to allow him to fondle and ultimately suck on her large breasts.
She had never had any sexual attraction to him before, but seeing and fondling his huge cock had clouded her rational thoughts. She knew that what had happened was so wrong, but yet she did it. She vowed to fuck her husband soon, so that she wouldn’t be tempted to fuck her very own son first.
Throughout the day, teasing and exposure was prevalent both out on the lake and back at the cabin. Mark was called again to apply lotion to his mom’s back and he copped a couple feels of her side boob during the application. When doing her upper thighs, the side of his hand had come in contact with his mom’s covered pussy. Both knew that her pussy was wet and needy.
Meanwhile Maggie donned her short skirt and half-top again, teasing her father with glimpses of her bubble butt (as she bent over into the cooler), her bare pussy (as she relaxed on the seat), and the bottom half of her breasts (as she stretched or the wind blew).
Both parents needed sex, as did both of their kids. Hopefully they would be having sex tonight.
After a day of teasing, both “couples” returned to their respective positions as family members, although all extremely aroused from the day’s activities. After cleaning up from their day at the lake, Tom and Alice went into town again for dinner and dancing (although Tom was not particularly fond of dancing).
After they left Mark jumped in the hot tub. Maggie, wanting to hear the latest exploits of her mom and brother, donned her bikini and went to join her brother in the tub.
“Hey.”
“Hey, you!”
“How was your week?” Maggie asked.
“Ok. I guess.”
“You guess? Did you get laid?”
“Are you kidding? I’ve been stuck with mom all week.” Mark complained.
“Stuck? I thought you liked being around her?”
“I’m sorry. Yeah I do. It’s just that… oh forget it.”
“Talk to me Bro. What’s bothering you?”
“I spent the whole week with mom and never got further than getting another handjob. Oh, and getting to suck on her tits.”
“What?! And you complain?”
“I’ve got a serious case of blue balls.”
“I really want to fuck her, but I don’t think it’s going to happen. What about you and dad. Did he get some of that Blue Ribbon pussy?”
“Blue Ribbon. I like that.” Maggie giggled.
“Do you really think my pussy is Blue Ribbon material?”
“Absolutely! Once dad gets a chance to experience it, he’s gonna regret not taking advantage of your willingness earlier.”
“Thanks bro. So what’s this about sucking mom’s tits?”
“We had been drinking while tanning and I could tell that she was getting tipsy. I talked her into letting me see her tits, since she got to see my cock. She finally agreed and when I saw them, my cock rose out of my speedos. I moved her hand to my cock and she stroked it for a bit. With her eyes closed, I leaned in and began sucking on her tits. It was too much for me and I came. Then she ran off to her room and nothing else happened.”
“Wow, that’s fucking hot.”
“So, nothing happened with dad?”
“Not really. We both sneaked peeks at each other’s exposed body parts, but we didn’t get physical. He got hard from checking me out and I extended an offer for him to fuck me, but that’s about it.”
The siblings then relaxed and enjoyed the warmth of the hot tub. Eventually, their parents returned home. Tom went to bed and Alice (being tipsy from cocktails at dinner) decided to join the kids in the hot tub.
“It’s nice to see that you guys haven’t decided to get naked again,” Alice teased her kids.
“Is it really nice mom, or were you hoping to see your son’s huge cock again?” Maggie teased and giggled.
“Stop that.” Alice blushed. “No truth or dare tonight?”
“We were waiting for you this time,” Maggie stated.
“Oh, ok. Who turn is it?”
“I’ll start. Truth or dare mom?”
“Truth.”
“Ok mom. Did you guys finish?” Maggie inquired.
“Finish?”
“Yeah. Remember? I interrupted you and dad having sex last week. So did you guys ever finish?”
“Huh?” Mark was confused by this new information.
“Oh my God. I can’t believe you’d ask that,” Alice said embarrassingly.
“Yeah bro. After I left you here last week, I went to ask mom for something. When I opened their door, dad had just pulled his cock out of mom and scrabbled back to the bed. Mom lowered her nightgown, but it was obvious that they were fucking.”
Maggie could see the disappointment in her brother’s face. So she tried to console him.
“I saw dad’s fully erect cock and it’s not even close to your size. Right mom?”
Alice saw the disappointment on her son’s face also and embarrassingly said, “She’s right Mark. Your penis is much larger than your father’s penis.”
That brought a smile to the young man’s face.
“So, did you finish mom?”
“Unfortunately, no Maggie.”
“Wow. You must be super horny.”
“My turn” Alice interrupted. “Truth or dare, Maggie?”
“Truth”.
“Ok Maggie, what’s with the continuing your exploration with your father?”
“What?”
“I overheard you and your father yesterday, talking about continuing your exploration. What were you talking about?”
“Oh… we went further out on the lake and found a remote island, so I was…”
“Bullshit!” She smiled. “I heard you offer your father sexual favors during your exploration conversation, so be honest with me. Have you and your dad messed around?”
“No,” Maggie confidently responded.
“Mark, your turn.”
“But…” Alice tried to get more info.
“One question, mom.” Maggie smirked.
“Truth or dare mom?”
“Truth.”
“Hmmm. Let me think.”
Thinking that maybe his mom may have had thoughts of fucking someone other than her husband and that he may have a chance at fucking her, Mark went for broke.
“Have you fucked anyone but dad, since you’ve been married?”
Both women’s jaws dropped at that question.
“Oh my God, Mark! Maggie said.
“Young man!” Alice was about to scold him.
“Wait mom. It’s an easy question to answer if you haven’t. Your reaction leads me to believe that you have.”
A tear formed in Alice’s eye as she looked down defeatedly. Mark apologized and went to hug his mother.
“I’m sorry for putting you on the spot mom.”
“It’s just that…,” She started to explain.
“So you have?” Mark whispered.
Alice nodded.
“Wow mom. I’ve always thought that you and dad were a happy couple.”
“We are happy!” She said frustratedly.
“Happy? Then why would you cheat on him? I would never have thought that you would cheat on dad.”
“I didn’t cheat on your father!”
“Mom. If you fucked another guy, then….,” Mark realized (mid sentence) that maybe his father knew.
“He knew?”
Alice looked down again defeatedly.
“Hold on. So are you guys swingers?” Excitement rushed through him thinking that now he may have a better chance at fucking his mom.
“No. We aren’t swingers.”
“Were you?” Her son asked her.
“It’s complicated.”
“Mom, we’re adults. You can tell us.”
“I just never realized that what your father and I had done in the past, would ever be brought out, especially not to our kids.”
“Mom, we’re adults! We can handle anything that happened in the past. Having multiple sexual partners is actually pretty cool.”
“Cool?”
“Yeah. But even back then, what you and dad did to spice up your sex life is perfectly understandable.”
“I know. I’m just so embarrassed.”
Alice looked at Maggie and Maggie realized that her mom wanted alone time with her son.
Being shocked and realizing that Mark needed to console his mother, Maggie decided to leave the two alone.
Once Maggie left, Mark continued…
“So dad was aware of you having sex with another man?”
“Oh yeah!”
“Oh yeah? What does that mean?”
“When we were younger, your father and I experimented with other people, to spice up our sex life.”
“So you guys were swingers?”
“Not exactly.”
“Then what?”
