I sucked Yuri's long, dark cock into my eager mouth, and tickled the bottom of his glans with my tongue. The catch in his breath told me I'd done it just right...and my own breath caught as I felt cautious, slim fingers explore the outline of my cunt lips, dipping inside to feel the hot, wet stickiness of my interior before moving down to massage my clitoris. I jumped, and Yuri moaned contentedly. Given his Mom's training, I knew he wasn't going to come anytime soon, so I slurped eagerly on his seven inches as I heard Mark start to pant behind me. He'd already come all over Marina once and filled my mouth with his spunk soon after, so I hoped that despite his inexperience, he'd at least be able to hold back until he managed to pump my pussy a few times.
I was looking forward to that...so much that I could feel my juices dribbling down my legs. I couldn't help it -- I wanted that thick teen cock more than I'd wanted anything in my life, despite the fact that just a few hours before Mark hadn't seemed sexy to me at all. Now his smooth-skinned swimmer's body was probably the sexist thing I'd ever seen or felt in my life.
Mark groaned as he rubbed the swollen head of his cock across my drooling hole, and I matched him, humming around Yuri's cock in a way that had him groaning, too. I pulled off long enough to gasp, "Put it in, baby, please! Fuck me hard!" Then I went back to bathing Yuri's dick with my spit.
Mark, such a lovely boy, just couldn't hold back; he slammed his eight inches into me all at once, and literally screamed as my cunt spasmed around it, driving us both over the edge of orgasm. Yuri's cock fell out of my mouth as my own orgasm exploded through me, little sparkles igniting the nerve endings in every erogenous zone of my body in the most pleasurable way imaginable. Poor Yuri; as I passed out, I saw Marina taking over, doing her damnedest to bring her son to orgasm with her mouth.
I just couldn't believe my luck: here I was, enjoying the best sex of my life with two of the hottest young studs in America, and one of them was my own son.
Funny how these things happen.

When us nudists tell you that we prefer to go without clothing because it's freeing and natural, you can take that to the bank. That's why we congregate at nudist camps and resorts, so we can be with others who won't go ape-shit if a woman wants to go topless...or bottomless, for that matter.
But anyone who tells you that there's not all kinds of sex going on at any nudist camp, especially the adults-only kind, is just plain lying. We nudists like seeing other people nude and checking out what they're equipped with...and getting it on with the ones who turn us on. After all, sex is natural, too.
I'd raised my son Mark as a nudist since my husband skipped out when he was three. For his eighteenth birthday, which fell in July, we went an adults-only nudist camp in the Poconos, his first. I figured he might enjoy finding a few girls his age among the cuties attending, and I wasn't adverse to a little slap-and-tickle from the random man myself.
The second afternoon, I was absolutely amazed to run into an old acquaintance from college, Marina. She was there with her handsome son Yuri, who had the most amazing six-pack abs, and jet black hair that fell in ringlets to his shoulders. He didn't say much as Marina and I caught up in the lounge by the pool; he just sat there and looked at me with smoldering eyes, in a way that made my pussy tingle pleasantly. I have to admit, I'm pretty well preserved for my age, which is somewhat north of 40. So is Marina. Plus, she was pleasantly brown from the sun, and her body was completely hairless, right down to her glistening mons (not that I was looking). Her tits didn't sag at all, and they were capped by nut brown aureoles that, apparently, Mark just couldn't keep his eyes off of.
I have to say that I was proud of my young son: in the best nudist tradition, he'd conquered his erection reflex, and just lay back in his chaise longue looking at the attractive older woman through slitted eyes. She kept glancing back at him, too, and if his penis twitched occasionally, I couldn't blame him. He seemed especially interested when Yuri stood up and, grinning, rubbed some suntan lotion into his mother's muscular back as her ample breasts wobbled from the motion. What a lovely boy Yuri was!
It's no mother's bias to say that Mark is himself a very great-looking kid. He's got that all-American boy look, with a swath of tousled red-brown hair on his head, but only a few wisps elsewhere. His smooth body contributes to his excellent ability as a competitive swimmer, and the exercise itself has chiseled his musculature into the kid of sharp relief you generally see only in statues like Michelangelo's David. He wasn't as dark of skin and Marina and Yuri or even me, but some of that was genetics; he did have a light over-all tan, with no swimsuit lines since he likes to sun worship in the nude. Right now he was perspiring a bit, and I suppose the overall package was rather fetching; certainly, the girls who kept glancing at him all thought so. But he wasn't paying them a lick of attention.
There are two things about Mark that worry me sometimes. One is his size; he looks about thirteen, even though he's eighteen. Second is the fact that he can be completely oblivious to other people's signals sometimes.
After chatting with Marina for an hour, I looked at my son and said, "Marky, I'm getting a little thirsty. Could you get us all a soda over at the snack bar?" I dug into my purse and handed him some cash.
He somehow tore his eyes off Marina and looked at me for the first time in a while. His face looked a little flushed. "Okay, Mom, I can do that." As he stood up he said, "Hey, uh, Yuri? I think we need two people to carry all the sodas."
Marina nudged her son. "Go help Mark, Yuri. Get to know each other a little. I think we're going to see a lot of Cynthia and him this week." She lay back in her chair, grinning, as they walked off. As soon as they were out of earshot, she said, "You have such a gorgeous boy."
"Funny," I laughed, "I was just about to say the same about Yuri."
She sat up suddenly and leaned toward me, that smoldering look I'd noticed in her son's eyes now in hers. In a low voice she asked, "How big is he?"
Frowning, I said, "Mark? I guess he's about five-five. Look, I know he's a little short for his age..."
"No! How big is he, hard? What are his measurements?"
My eyes widened as I finally took in her meaning. "I, um, how would I know that?" I stammered.
"So you're not training him?" She lay back with a sigh. "What a waste. He's so beautiful..."
Now it was my turn to lean forward and use a low voice. "What do you mean, training him?"
She leaned forward until she was close enough to kiss me. "You know," she whispered, licking her lips lasciviously.
