I watched my nephew masturbate in the shower. It felt sort of wrong to look, as though it was a private moment, but he’d left the bathroom door wide open and the whole bathroom, including the shower area, was clearly visible.

I’m Gwen and maybe you read about me in my Kelly series, which probably still has more stories to come. Kelly is my sixteen-year-old daughter. I’m forty years old and your basic mom who likes sex a lot. My husband, Greg, and I have fucked a lot of different people, men and women, especially in the past five years. Until a few months ago we’d always done this at a hotel, but nowadays we sometimes included Kelly in our sex play, so we simply had people come to the house.

Nephew Michael, however, was just supposed to be a visit. Yes, he’d be here most of a week, a long time, but he had at least a week off from college and decided he wanted to see Disneyland, surf at Pacific Beach, and do some other things suitable for an eighteen-year-old boy. Which, apparently, included masturbating in my shower.

I passed the guest bathroom on the way to the laundry – I was holding the hamper in my hands as I looked at Mike. The shower screen was glass that went eighty percent of the way to the ceiling. The glass had a very slight haze and some water streaks, but I could readily see Mike’s hand on his cock, quickly moving back and forth.

Then I heard, “Gwen! Fuck me! Like that! Fuck my hard cock!”

He didn’t appear to be looking in my direction, but he could see me as easily as I could see him if he turned his head. His body looked to be fairly filled out with muscles carved in his shoulders and arms and I could make out bits of a six-pack in his abs. I love seeing abdominal muscles, men or women, although I’ll admit that mine, uh, aren’t visible.

He said more of the same, but the essence was that he was fantasizing about having sex with me. And then he came. He sort of yipped in a high voice, a very odd sound. I could see streams of cum shoot from his dick. As soon as he finished, I continued to the laundry, not wanting to disturb him.

You might think this is odd, my falling into sexual situations, but it’s really not. For one thing, guys think about sex all the time and women think about sex a fair amount of the time. It shouldn’t be surprising that many of us act on some of these thoughts. For another, having sex with my husband and my daughter and various other people keeps me open to sex as a regular event. I’d even say it’s nothing special except that it feels so good. Anyway, my much-younger nephew had just masturbated in front of me – not a big deal. That he thought about fucking me, well, I guessed that our fantasies could be whatever we wanted them to be. I won’t even hint to you about some of mine.

The next morning, I listened for the shower to start and walked over to watch. Yes, he’d left the door wide open again. I wondered whether that was just a teenage thing to do, probably not, or if he knew I was watching. He soaped his body and I saw his cock grow from soft and semi-small to big and hard. Mike did have a large cock, longer than my husband’s (which was on the short side) and almost as thick (Greg’s cock was kind of a sausage). Although I’d had bigger dicks, huge ones, Mike’s was simply large. I didn’t notice Kelly had walked up to me until she tapped me on the shoulder.

“Is that Mike?” she asked unnecessarily.

“Yes, it is. Now, quiet.”

“His dick is kinda big, isn’t it?” she asked.

“Shhhh.”

We both watched him masturbate until he came. It was much the same surge of ejaculations as before, a long shot, a longer shot, then several shorter ones. He’d started talking again as he got close to cumming, mentioning me by name several times and his cock and several of my body parts, especially my pussy, and he yipped when he came. He seemed to love my pussy, which he’d never seen.

“Come on,” I told Kelly and we left.

“I think he wants to fuck you,” Kelly said.

“Well, yeah, I think he wants to fuck anybody and anything. At least he’s doing it in the shower, not fucking his pillow or jacking off on the coffee table.”

The next morning, Sunday, Kelly beat me to our voyeur post and we watched together as Mike masturbated and yipped and came. This time, when he spoke, his story had changed.

“Kelly, you’re so beautiful, fuck my cock. God, I want to fill up your pussy.”

And like that. It was very similar to the previous two days, but this time it was my daughter he fantasized about. Kelly had put her hand over her mouth, partly in shock, maybe, but I could see she was smiling.

“You enjoyed being fantasized about, didn’t you?” I asked.

“Well, yeah, who wouldn’t?”

That night, at dinner, we all talked about the day we’d had. Mike had gone downtown and toured the Midway aircraft carrier and had tacos for lunch. Then I said what I needed to say.

“Mike, how come you shower with the door open? You know we can see you. Not just see you take a shower, but watch you masturbate. Every morning.”

This was news to Greg, who seemed more interested than shocked. Kelly put her hand to her mouth again, I don’t know why. Mike flushed a little, but not that much, and put down his fork. He looked at each of us before he said anything.

“I, uh, well, I was thinking that maybe one of you would watch me take a shower. And… you know. With my hand.” He was obviously struggling. “And, uh, cum.”

He had now turned crimson, but he kept his eyes up.

“Well, sounds like it worked,” Greg said. “Congratulations!”

“You like to masturbate in front of people?” I asked.

“Well, yeah. It gets my motor running, if you know what I mean. Someone else to enjoy the spectacle, I guess. It’s best when I know people are watching instead of when I’m just guessing. Or hoping.”

That sounded a bit grandiose to me, but he was only eighteen.

“You knew I was watching?” I asked. “Kelly and me?”

“Yeah, at least I did, starting a couple of days ago. That was you, right? Then you and Kelly yesterday and today? Watching me jerk off?”

“What did you think, Kelly?” I asked her.

“I loved it! It was maybe better when I thought he didn’t have any idea we were there, but I still like it. It’s fun to see someone cum, especially a guy. Right, Dad?”

“Um, sure.”

It was obvious we were done eating.

“Would you like to simply masturbate in front of us, Mike? Maybe all three of us?” I asked. “We’re not shy and neither are you.”

“I don’t know,” he said. “I’ve done the shower trick many times and I’ve jerked off other places where I would be seen, but I’ve never just done it in front of people. Like a stage act or something.”

“Well, I’d like to see it,” Kelly said. She had come a long way from the girl a few months ago who hadn’t even seen her dad naked. “Stage act or whatever.”

“I’ll jerk off with you if you want,” Greg said.

Mike’s eyes widened. “You would do that? In front of, you know, your daughter?”

“Sure,” Greg said. “Nothing she hasn’t seen before.”

I couldn’t understand why Greg was being so open about having sex with his daughter. We weren’t shy about sex, but I was scared shitless that some stuffed shirt would learn about it. Incest is illegal in California, I’m pretty sure, definitely with a sixteen-year-old daughter.

Mike thought about that for a minute. I have no idea what he was thinking, but he’d obviously sorted out that sex in our family was a group thing.

“Well, OK, I guess, although it’s a little hard to believe you. Do I just stand up and drop my shorts or what?”

“No,” I laughed, “if we’re going to make a mess, and it sounds like there’ll be jizz everywhere, let’s all go to our bedroom. King-sized bed and all.”

We moved to the bedroom. Mike and Greg took off their clothes and they both sported hard cocks. It was obvious that Mike’s was bigger. And Mike’s ass was tighter, as was his tummy. I could feel myself getting wet. They pulled down the covers and climbed onto the bed. Side by side, they began to fondle their dicks.

Mike’s cock was lovely. Some aren’t, but Mike’s was stiff and straight, its big head circumcised. His balls, though, were as ugly as the next guy’s and mostly drawn up tight to his dick. A guy’s balls have always seemed like a design failure to me, although I’ve seen them swinging on lots of kinds of critters, so I guess they work the way they’re supposed to.

“You girls could help,” Greg said. “Give us something to look at, at least.”

Kelly and I looked at each other and shrugged. A minute later I was naked and she had her top off. She wasn’t wearing a bra and her small breasts poked out of her chest with hard nipples. I sat on the bed next to Greg and Kelly stood close to Mike’s side of it. Mike moved to the edge and began to run a hand along Kelly’s breast and nipple as though he’d forgotten all about masturbating.

Greg saw that and he bumped himself to lie closer to Mike. His hand went down to Mike’s cock.

“Hey,” Mike said. “I’m not gay. I mean, you know, being gay is cool and all, but that’s not me.”

“Well, I’m not gay, either,” Greg replied. “But I am bisexual and your cock is especially appealing. You must be seven inches and I’m hardly more than five.”

Mike put his hand on Kelly’s pussy and she didn’t move away. In fact, she stepped closer, right to the edge of the bed. He rubbed her crotch through her shorts. Mike hadn’t actually told Greg to stop, so he had begun to stroke Mike’s dick. He did this for perhaps half a minute and, hearing no objection, Greg lowered his head and took Mike’s cock into his mouth.

“Hey,” Mike yelled. “What the fuck are you doing?”

Greg said nothing and kept sucking.

“I told you… you know, that feels good. It feels great. OK, Greg, you can suck my cock, but no kissing or anything gay. Cock sucking is fine.”

I felt left out (and not for the first time, either). I slid onto the bed and began to jerk Greg’s dick with my hand. Mike continued to rub Kelly’s crotch and unbuttoned and unzipped her shorts. We would have had a great daisy chain if Kelly would figure out a way to eat my cunt, but that seemed unlikely.

Greg deepthroated Mike, which I thought rather impressive. I began to suck Greg as I gave him a hand job. Both guys began to moan, not loudly, but steadily.

“I’m going to cum,” Mike said abruptly.

I don’t think he even finished the sentence before he jammed his cock into Greg’s throat and I could see his balls move as he came. He yipped some more, maybe a coyote yowl or something? Greg almost got all his cum, but at the end, he pulled his mouth off Mike’s dick, saliva and cum everywhere as he choked for breath. He jerked Mike’s cock so he would ejaculate the last bit of cum. Then, despite his sudden breathing problem, he came himself.

I’d been sucking the end of his dick. I loosened my lips just enough so that his cum would leak out of my mouth. I pushed against his cock with my tongue and felt the spurts against the top of my mouth. The feeling of cum dripping down my chin was as lovely as it was messy.

“Oh, boy,’ Mike said, “I’ll never be gay, but I can sort of see bits of it being more reasonable than I used to think.”

“Yeah,” Greg answered, “although Gwen is an awesome cocksucker herself.”

I smiled my appreciation and clambered to lie between Mike and Greg.

“Come on, honey, join us,” I told Kelly.

There was ample room for four to lie separately on the bed, but she took off her shorts and panties and lay with a leg between mine, her thigh on my cunt. We put our arms around each other and clung tightly. Our faces were just inches apart. I kissed her. I felt her fingers touching my cunt. My whole body shivered.

“Kelly,” I said, “I love you so much.”

“Me, too, Mom,” she said, pushing two fingers inside me.

My lips brushed hers repeatedly. Back and forth, her lips so soft. I opened my mouth a little and my tongue licked her lips. Kelly’s tongue inched out of her mouth and slid along mine. I put a hand on her breast and began to knead it. Pressing my lips against hers, our tongues began a lovely battle swirling around one another.

 I was sure the men were watching, but obviously, I had no idea what they were thinking. I enjoyed putting on a show – I loved being watched having sex. It didn’t occur to me later how much Mike and I were alike. I only wished I could see their faces.

I kissed Kelly deeply. I pulled her ass toward me and felt her cunt on my thigh. She began to rub against me. Her fingers continued to fuck me. We continued to kiss each other hard.

Suddenly, I felt a guy’s hand on my breast and from the roughness of the fingers figured it was Greg’s. I felt another hand, softer, on my other breast. I have to admit that my husband’s was much better. I stopped kissing Kelly and pressed my hands against the top of her shoulders, lightly pushing her down. She kissed me between my breasts and licked one where it met my ribs, a delightful feeling. Her head kept kissing its way down to my pussy.

She licked my thighs for a minute, then surprised me. She got up on her knees and said, “Slide down the bed a ways, Mom. Let’s 69.”

I slid down the bed, but as I did I wondered where Kelly had learned about sixty-nine. Probably with a boy, I guessed, although sex in my teenage years had been more direct, more wham-bam. It was difficult for me to picture a guy eating Kelly’s pussy while she sucked his dick. Still, it was more likely than that she’d stumbled across a girl to do it with. Wasn’t it? Or maybe she’d simply learned it from watching porn.

Her cunt eased down to my mouth. The boys had quit fondling my breasts and were now playing with Kelly, rubbing her back and her ass. My legs were spread open and my knees bent a little. Kelly’s thighs were closer together, but still, her pussy was right in front of me. I licked her labia, carefully avoiding her clit both for the suspense and because it was likely still too sensitive to be attacked by my tongue.

Kelly’s cunt was as tasty as ever, although tonight it was more raspberries than strawberries. All that juice, god, she was wet, tasted so good. The boys’ hands occasionally touched mine as they brushed her thighs.

Her tongue slurped my clit, but I was ready for it. After the first sudden jolt, I felt myself starting to warm up with arousal. She licked and sucked my clit and did little else, but it still felt terrific.

I lifted my head up and put my hands on Kelly’s ass. I licked the smooth skin, as tight as an apple, and pulled her cheeks apart. I began to lick just below her asshole. I could reach it with my tongue, but just barely. Kelly seemed to figure this out and she sort of sat up, leaning forward, and her asshole came directly into contact with my tongue.

I could see the boys reaching for her breasts, suddenly available. I licked around her asshole and Kelly wriggled her butt. I pulled her cheeks apart a little more and pushed the tip of my tongue into her hole. She sat back just a little and my tongue plunged into her maybe an inch. I wriggled it around, then in and out. Pulling my head back, I licked the length of her ass crack, my tongue touching both sides. I licked her down to the bottom of her pussy, then back up to the top of her ass. I pushed my tongue back into her several times.

“That’s enough, Kelly, back to regular pussy eating,” I said.

Her head came down and resumed licking my clit. She put two fingers inside me. They slid in easily and I could feel pussy goop leaking down my ass. Kelly licked me fairly hard.

I was mostly sucking her clit now, thinking that it was like a tiny version of the blowjob I’d just given Greg. I sucked (and licked a little) for maybe five minutes before I felt Kelly tense up. Her back arched and she growled. I kept sucking and used my tongue the best I could. She quit licking me and just rocked back and forth a little. She came with a small scream, followed by a small laugh. I could feel her tummy clench and relax. Kelly came for maybe ten seconds. She said “Oh, god” a lot.

Kelly sort of fell off me and onto her father, slowly turning around so we would all be facing the same direction. I sidled toward Mike and we briefly lay side by side, face up. I felt Mike’s hand on my boob.

“I don’t think you came,” he said. Good of an eighteen-year-old to notice.

“It doesn’t matter,” I...
