It came about that both Heather and I were alone one weekend due to our spouse's travels. I had to get down to the beach house to open it up for Spring and Summer. It seemed only logical to ask her to help, so to speak. And we could spend the whole weekend together.
===Heather===
Despite our ongoing affair, we had never spent the night together, always being careful to return home from whichever house we had used. I was nervous to have him pick me up at home that Friday night, so I took a walk around the neighborhood. He stopped for me at a spot where nobody knew me. We played with each other in the car as much as we could til he drove up to the driveway of their beach house.
===Ryan===
We weren't expecting any rain or wind that would kick up salt spray at the beach house, so I didn't use the garage and didn't realize that there were already two cars parked in there. Heather and I went in the front door and started kissing, caressing, and as our tradition, undressing. Then I led her to the screened in veranda on the waterfront side of the house and got the shock of my life.
There were four naked college age teens on the floor on blankets they had laid out there. Among them were Abby, my daughter, and Noah, Heather's son. Noah's butt was moving down and up between Abby's legs and the other boy was vigorously licking the other girl. Heather let out a scream. Abby pushed Noah off and staggered to her feet, clearly drunk. "Daddy!" And then, "Oh my god, you're having an affair!" as she propped herself against one of the posts between two screens.
I didn't dawn on Abby for a few seconds that she was presenting herself in full frontal nudity. And for a moment, I couldn't help but notice how beautiful Abby's body was - and yes, she did shave her pussy. Noah was still sitting on the floor and covering his cock with both hands. The other two clung to each other as they cowered in the corner. The kids were staring at Abby's and Noah's naked father and mother. There were beer cans, condom wrappers, and used condoms scattered about.
===Heather===
"W, W, What are you doing here? Why aren't you in college? Oh my god! Oh my god!" I exclaimed as I grabbed one of the seat cushions to shield my nakedness. Ryan sort of hid behind me.
"We just took the weekend off," Noah, also drunk, explained. "What are you do .... Oh god MOM!! You're fucking him aren't you!?!?!?"
"Yes, it's true. .... But - Oh Oh OH - you have to keep it secret," I begged.
===Ryan===
"Ha ha. Don't let us stop you," the other boy chimed in in a mocking voice, pushed the girl back onto the floor, pushed her legs apart, and positioned himself to enter her.
I dragged Heather to our bedroom at the other end of the house. We closed the door and sat on the bed shivering. "Do you think they'll keep our secret?" she asked. "Yeah probably," I replied with a load of doubt in my tone. We just hugged each other for the longest time until hugs turned to caresses, and caresses turned to fondling, and fondling led to my cock buried in Heather's pussy.
I didn't realize that someone had opened the door silently and slipped in to the room. "Mind if we join you?" It was the other two kids. "I'm Tyler, this is Brittany." But they didn't wait for our answer, and just flopped down beside us on the king size bed. After I got over that shock, I continued fucking Heather. I could tell that Brittany, who was on top, was sliding down over Tyler's cock.
When Heather wanted to get on her knees I pulled out to let her turn over. Before I could resume, however, Brittany grabbed my slippery cock and rubbed it as she guided it back into Heather's love hole. She didn't let go and her fingers slid back and forth over my shaft as I pumped Heather. I didn't last long at all with that going on.
Brittany yanked my erupting cock out of Heather's body and took the remaining spurts in her mouth. The next thing that happened, Tyler pushed two of his fingers into Heather's pussy while Brittany continued to ride him. When Heather realized what was going on, she exclaimed, "Oh No." Nonetheless, she eventually rolled out from under me and Brittany. To my dismay, she let Tyler climb between her legs. Brittany and I rolled off in the other direction and I found her smoothly shave pussy inches from my mouth as she crept up over my face. I heard the familiar sounds of Heather's orgasm along with Tyler's.
===Heather===
I couldn't believe I'd just had sex with this total stranger 20+ years younger than me. And there was Ryan doing 69 with this girl. I guess I had been too deep into my arousal to come to my senses and stop things. Plus that Brittany girl had stolen Ryan away from me. Somehow it seemed OK. After all, I could tell Tyler was wearing a condom. I supposed the only reason Ryan wasn't fucking Brittany was she hadn't brought a condom into the room, though that proved not to be the case. I watched Tyler slide his rubber off, tie a knot in it, and throw it on the floor.
Thankfully, Noah and Ally were still on the veranda. Or so I thought. To my horror, they had been watching for I don't know how long. He was standing behind her with one hand on her boobs and one hand between her legs. I could see he was grinding against her back. She turned and leane against a dresser and, in plain view of their respective father and mother, had doggie style sex. Then, I watched Brittany, sans condom, slide down Ryan's body, hold his cock up and ease down over it. They were the last two to finish.
When we all came to our senses, we all decided that we would end this business as soon as everybody sobered up in the morning. Everybody helped clean up the last night's mess. Noah took me home in his car. Ally stayed with Ryan to help get the beach house ready for summer. The other two collegians drove off, never to be seen again, I hoped.
===Ryan===
Ally and I put in a hard day's work pulling out beach furniture and kayaks, vacuuming, dusting and running the dishes throught the dish washer. That evening, we grilled hamburgers and hot dogs and ate them sitting on the veranda sofa. We didn't talk about the previoius night, though it was clear we were both pondering what that all meant. Then Ally asked me, "Did you ever think about having sex with me?"
"I don't know," I lied. Then, "I suppose, yes, but you know."
"I dreampt of having sex with you ever since my period started," she told me. "Did you like my body last night?"
"You're a beautiful young woman. You have a lovely body, though I never expected to see you like that. ... You know, naked." Strangely, or maybe not surprisingly, I noticed my loins beginning to swell as I recalled what I had seen.
"I wish we could have sex tonight," she continued nervously. She looked me in the eyes with that look and put her hand on my leg. "Nobody would know. And I'm a grown woman now, not a child. And I'm on BC. We all just used condoms for safety last night," she blurted out in rapid succesion to get it all out before I could interrupt.
"Oh God," I muttered. Ally was wearing the shortest of short shorts, so my hand landed on the bare skin or her leg. She sighed and my hand slid higher and higher til i cupped her pussy through the fabric. She bucked in response and I took her still clothed breast in my mouth. It was time to undress her. I pulled her tee shirt up and dragged her shorts and panties off in one motion. That beautiful body I had seen across the room last night was mine to possess tonight.
I couldn't believe I was tasting my daughter's sex and feeling the heat of her ready vagina on my fingers. I held her youthful breasts in my hands as we made love the first time, and we made love over and over that night and the next morning.
The Monday at work, Heather remarked, "We were bad weren't we." I felt like I had to apologize and so I did, but I've never told her about Ally.
===Heather===
We rode silently most of the way home. Then I started the conversation, "I hope you don't think too badly of me. Ryan and me were always good friends at the office. I still love your Daddy, but Ryan and me, our attraction to each other became more than we could resist."
"I was kinda shocked. ... But I never could see how anybody could go through life having sex with only one person." And when I asked how many he had been with, he replied, "Five or six. .... no, hehe, eight if you count the party at Barry's house."
"Ryan was only the third man I ever had sex with," I admitted.
"It was awesome watching you get screwed, hehe."
"I suppose you wanted to join in," I teased, but I realized this may not have been the smartest thing to say.
"Every boy who has a mother as hot as you wants to fuck her."
"YOU!?!?! ... ... Oh God," I stammered. Watching a handsome son turn into a man does lead to all kinds of fantasies I admitted to myself. And why not after last night. "Really?"
We were pulling into the drive at that moment. In the garage, we leaned across the front seat and started making out, though for some reason, we didn't kiss. I had my son's cock in my hand and his fingers were plunging in and out of me. We ran inside. I leaned against the washer in the mud room and let him tear my clothes off. He slid his own shorts and tee off and grinded his cock between the wet folds of my pussy. We slid into the kitchen and I sat on the table with my legs wide open and dangling over the edge. I knew it was wrong, but I begged him to fuck me. He didn't wait and penetrated me the first time. After a few uncomfortable moments we moved onto the sofa where I knelt on the cushions and held onto the seat back. He licked me to orgasm before he entered me from behind. Standing up like he was, his thrusts were powerful and deep.
"Let's go in the bedroom," I offered. After pulling down the covers, I laid on my back and wrapped my legs around him and pulled him into my deepest secrets. He squeezed my boobs while he thrusted in me. It wasn't long before my vagina was filled to overflowing with his youthful semen.
I took his sagging cock in my mouth and brought it back to full erection. He lasted forever this time and I went through two more orgasms as we changed positions several times. We were spooning when I again felt his juices spewing forth inside me.
We ate dinner silently and shared a bottle of wine with nothing but robes on. When our plates and glasses were empty, I slid down onto the rug and motioned him to slide his chair back. His cock came to life in my mouth and I took in the strong flavors of my sex and his. He loved when I swallowed his release. Then he led me over to one of the easy chairs and sat me there. I was amazed when he ate my pussy with the mess that it was. When he was ready, he climbed up over me. My man/boy entered me again. Once more, we finished in the bed and fell asleep.
I awoke with my pussy being licked. "Oh, Ma...," OMG it wasn't Matt. And it wasn't Ryan. Noah climbed up over me and slid his cock in. Oh god it felt good. Later, we made love again. And again.
