It came about that both Heidi 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. We could spend the whole weekend together.

===Heidi===

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.

===Roger===

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. I had been hard for most of our drive, and I felt the pressure building down below as we walked up the steps to the porch. We started kissing while we were still outside. I took Heidi's little boobs in my hands and stroked them through her shirt while she reached down to my crotch.

As she started rubbing the fabric of my jeans, I reached between her legs and, through her shorts, pressed my hand against her pubic area. Our breathing got heavier as our desire built, but I wasn't comfortable going further out front like that. We went in the door and started undressing. I unbuttoned her cotton shirt and Heidi pulled my polo shirt off. I pulled her lacy bra cups down and started twisting her nipples. She pulled my belt open and unbuttoned my jeans. I reached around behind and unclipped the bra. My zipper went down and Heidi grabbed the bulge in my jockeys.

===Heidi===

The cabin was quite rustic. From the outside, I could tell it was large enough to sleep a big family. On the porch we resumed the foreplay that had been happening as we drove. I would have happily gotten naked right outside the door, but Roger thought better of that and led us inside. We started ripping our clothes off as soon as the door closed. My tits loved his attention there. His cock was so hard in my hand. When he reached into my shorts, he felt again how ready I was for him. Everything was soaked. He let me suck on his cock, and then, he knelt in front of me and lapped at my pussy. My juices were running down one leg.

===Roger===

Once we were naked and had had a little fun with our arousal, it was time to take her to the screened-in veranda on the waterfront side of the house. I wanted to lay her on a lounge chair and fuck her in the cool air with the sounds of waves lapping at the beach. But when we opened the door to the enclosure, I got the shock of my life.

There were four naked college age teens on blankets spread out on the floor. Among them were Abby, my daughter, and Ned, Heidi's son. Ned's butt was moving down and up between Abby's legs. The other boy was vigorously licking the other girl. Heidi let out a scream. Abby pushed Ned 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. Ned 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 youths were staring at Abby's naked, erect father and Ned's naked mother. There were beer cans, condom wrappers, and used condoms scattered about.

===Heidi===

"Wha, Wha, 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. Roger sort of hid behind me.

"We just took the weekend off," Ned, also drunk, explained. "What are you do .... Oh god, MOM!! You're fucking him, aren't you!?!?!?"

I was unable to speak for a few moments, but then I replied, "Yes, it's true. ... But - Oh Oh OH - you can't tell anyone," I begged.

===Roger===

"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 Heidi to our bedroom at the other end of the house. We closed the door and sat on the bed, shivering. "I'm so sorry!" I said.

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 Heidi's pussy.

I didn't realize that someone had opened the door silently and slipped into the room. "Mind if we join you?" It was the two stranger 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 Heidi. I could tell that Brittany, who was on top, was sliding down over Tyler's cock. Soon, her boobs were flopping just to the right of me as she rode him.

When Heidi 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 Heidi's love hole. But she didn't let go. Her fingers slid back and forth over my slippery shaft as I pumped Heidi. I didn't last long at all with that going on.

Brittany yanked my erupting cock out of Heidi's body and took the remaining spurts in her mouth. The next thing that happened, Tyler pushed two of his fingers into Heidi's pussy while Brittany continued to ride him. When Heidi 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 shaved pussy inches from my mouth as she crept up over my face. I heard the familiar sounds of Heidi's orgasm along with Tyler's groans.

===Heidi===

I couldn't believe I'd just had sex with this total stranger 20+ years younger than me. And there was Roger 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 Roger away from me. Somehow, it seemed OK. After all, I could tell Tyler was wearing a condom. I supposed the only reason Roger wasn't fucking Brittany was that she hadn't brought a condom into the room, though that proved not to be the case when she finally unwrapped one on his shaft. Tyler slid his rubber off, tied a knot in it, and threw it on the floor.

Thankfully, Ned 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 leaned against a dresser and, in plain view of their respective father and mother, had doggie style sex. Then, I watched Brittany slide down Roger'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 previous night's mess. Ned took me home in his car. Abby stayed with Roger to help get the beach house ready for summer. The other two collegians drove off, never to be seen again, I hoped.

===Roger===

Abby and I put in a hard day's work pulling out beach furniture and kayaks, vacuuming, dusting, running the dishes through the dish washer, and gingerly throwing last night's condoms in a trash bag. That evening, we grilled hamburgers and hot dogs and ate them sitting on the veranda sofa. We didn't talk about the previous night, though it was clear we were both pondering what that all meant.

Then another shock. Abby 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 dreamt 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 and, you know ..."

"Fucking," she finished my sentence. 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 added nervously.

I stared at her in stunned silence.

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 succession to get it all out before I could interrupt.

"Oh God," I muttered. But Abby was wearing the shortest of short shorts and looked so appealing. I tentatively put my hand on the bare skin of her leg. She sighed and pulled my hand higher and higher til i cupped her pussy, my daughter's pussy, through the fabric. Was this really happening?

She bucked in response, and I took her still clothed breast in my mouth. Hers were a nice size, especially compared to Heidi's. Should I undress her? I pulled her tee shirt up off her bra-less chest. She laid back on the sofa and I got in front of her. I dragged her shorts and panties off in one motion. Was that beautiful body I had seen across the room last night mine to possess tonight?

I couldn't believe it as I was tasting my daughter's sex and feeling the heat of her ready vagina on my fingers. I climbed over her and, after a brief hesitation, slid my cock in. I held her youthfully firm breasts in my hands while my shaft made love to her. Her body bucked and shook.

I managed to hold on long enough to let her get on her knees. That lovely, shaved pussy was presented in full view. I licked it until her orgasm crested and entered her again. I finished a few moments later inside of her. After I pulled out, a blob of her father's semen, the semen that had started her life, oozed out of her vagina.

We made love over and over that night and the next morning as we went about our chores.

That Monday at work, Heidi 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 Abby.

===Heidi===

We rode silently most of the way home. Then I started the conversation, "I hope you don't think too badly of me. Roger and I were always good friends at the office. I still love your Daddy, but Roger 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." I wondered if he had practiced that line during the previous silence.

When I asked how many he had been with, he replied, "Five or six. .... no, he he, eight if you count the party at Barry's house."

"Roger was only the third man I ever had sex with," I admitted. "Did it bother you, seeing me have sex? And with two men!"

"It was awesome watching you get screwed, he he."

"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 inside my shorts. 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 to 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 thrust in me. It wasn't long before my vagina was filled to overflowing with my son's youthful semen.

I took his sagging cock in my mouth and brought it back to full erection. He lasted forever this time. 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 for the second time.

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, M..." OMG it wasn't Mell. And it wasn't Roger. Ned climbed up over me and slid his cock in. Oh god it felt good. Later, we made love again. And again.

Before his father came home, I told Ned, "I don't think this should become a regular thing. He agreed and headed back to school.

And I've never told Roger.

Ned was back home during his winter break. One morning after his father had left for work, he came up behind me and took hold of my tits. With his lips touching my neck, he asked, "Do you want to fuck?" It would have been dishonest for me to say no.
