"You go first," Mary told John as they lay next to each other on John's full sized bed.
"Hmm, okay," he started, "there was this one time in high school. It was me, my girlfriend, and her friend and we decided to go swimming. It was late so we just went in our underwear. I wasn't really expecting anything, I swam a couple of laps, and then looked over. The girls were sitting on the steps in the shallow end, kissing."
"Go on," Mary said, as her hand massaged John's semi-hard on through his boxers.
"Okay, but you're distracting me," he replied. "Of course I swam over to them to get a closer look. I'd always thought the other girl was really pretty and most guys are happy to see a pair of women making out. Once I got close my girlfriend invited me to join in. Soon I was sitting in between the two of them, kissing and touching both. My girlfriend took off her bra and then asked her friend if she could remove hers. She agreed and all of the sudden, there I was with two topless girls."
"Lucky guy," Mary smiled as she continued rubbing John's dick.
"It was nice, they had very different bodies," he explained. "My girlfriend was shorter with large breasts, though not as big as yours. The other girl was beautiful, though, slim and dark-haired, very sexy."
Mary felt a little jealous listening to the story about her boyfriend with two women. This had been her idea though, to share sexy stories from their pasts. It was supposed to be part of getting to know each other better, but now she wondered if she really wanted to continue. "Were you hard?" she asked.
"Oh yeah, very. It was a little embarrassing because my cock was poking out through the leg of my boxers, which aren't really substantial enough to hide me when I'm really hard. We kept making out and my girlfriend started to play with it as I kissed her friend and rubbed her breasts. I think her friend started to get uncomfortable though, and after a while she excused herself. After that my girlfriend and I had sex and then went to bed. It was a little disappointing but still a hot memory."
"Yeah it sounds like it," Mary was relieved, but still a little jealous. She was strangely turned on by the thought of her boyfriend with another woman but it bothered her on some level.
"Okay, now your turn," John said. He was getting very horny thinking about his near-threesome and feeling his girlfriend tease his cock. He had reached over and was now playing with her pussy through her panties and massaging her 36DD breasts through her t-shirt. Her nipples were hard as pebbles, a sure sign that she was also getting aroused.
"Well, your story reminds me of the time I went skinny-dipping in my friend's pool," Mary replied. John's ears perked up. "It was me, my friend Jenny, and two guys. It was a little weird because one of the guys was her ex-boyfriend who I had slept with a couple weeks before. This was during the summer after high school where I was experimenting a little bit, you know."
Now John started to feel jealous. He knew of course that he hadn't been Mary's first, but he'd been under the impression that there had only been a couple guys before him. Nevertheless, as he thought of Mary with other men a bit of blood rushed into his cock, causing it to throb a bit in Mary's fingers. "Go on," he said with a lump in his throat.
"I was afraid that Jenny was mad at me," Mary explained. "She knew that I had fucked her ex but, as it turned out, she didn't really mind. We had patched up our friendship that night, the guys were playing video games or something, and as it got late, Jenny suggested that we jump in the pool. So we went out to the patio and started stripping down. Jenny had done this before, she was bad girl," Mary giggled, "but the rest of us were sort of nervous. She took her clothes off first. Her body is sort of the opposite of mine. She's blonde and skinny with small breasts." Mary was raven-haired and voluptuous, with a surprisingly large set of breasts for a girl of her size.
"I was next," she continued, "and soon the two of us were naked in front of the boys. We jumped into the pool as the guys stood and watched. We wanted them to join us though, and Jenny started egging them on. We could, ummm, how can I put this? We could tell that they were excited," Mary laughed. "We'd both been with Eric, Jenny's ex, so there were no surprises when he took off his shorts."
"Was he big?" John asked nervously as he rubbed the front of Mary's damp panties.
"Haha," Mary laughed. "Eric, no, not really. I mean, he wasn't small, but he wasn't as big as you."
John felt a little relieved, his proud seven inches were still unchallenged. "Go on," he told her.
"So we were all naked except for the other guy, Scott," Mary said. "And Jenny and I started to tease him like 'Come on, give us the full show' and stuff like that. It looked like he was really hard, so we thought maybe that's why he was reluctant. So Scott, who looked a little embarrassed, drops his underwear," her voice dropped a little. Now it was her turn to make John jealous, "And it was just huge."
The lump returned to John's throat. "How big?" he asked.
"It was really big," she told him, giggling. "REALLY big, I mean, too big honestly. I didn't measure it or anything, but ..."
John gulped, picturing the scene. "Show me," he told her.
"Well," Mary said as he soft grip snaked John's raging hard on out of his boxers. "Maybe like this," she said, holding her fingers about two inches beyond the end of his raging cock. "I gasped," she said, continuing her story. "I mean it was definitely the biggest penis I've ever seen...in person. And Jenny was laughing, 'That's the biggest white one I've ever seen, I want to see it hard!' she said. I just watched as Jenny started saying things to try to get the guys hard. It wasn't difficult. Eric was already pretty erect, but Scott wasn't yet. I guess it takes a lot more blood to fill a big one, you know?"
John's dick throbbed in Mary's hands as images of his girlfriend ogling two nude men, one of them hung, raced through his head.
"So we watched as he started to get hard," she continued, "and it just kept getting bigger. It was long and thick. It was really interesting to see the comparison of two guys side by side. Different sizes, the directions they pointed, colors. It was hot. It didn't last that long though, they both jumped in the pool. I couldn't stop thinking about Scott's big penis, though, lurking down there beneath the surface," Mary laughed.
John's heart was pounding as he listened to the story, but his cock was hard as steel. Mary noticed, as she continued stroking his beautiful member. A stream of precum dribbled down over her fingers. She loved cocks, more than most girls. She loved watching them get hard and throb in her hands, mouth, and pussy. She loved how they were both hard and soft at the same time, how the veins stuck out in different patterns and the helmets flared with their bulbous tips. She loved how they were almost always darker than the other parts of the boys' bodies. She loved watching them cum. Most of all she loved making them cum. Mary couldn't understand how other girls could not love penises and how they could not love the taste, smell, and feel of a boy's cum. She'd seen more than a few cocks in her 23 years, but John's was her favorite and not just because it was attached to him. It was perfect, she felt. Big but not too big, perfectly proportioned, thick, veiny, with the most beautiful cockhead she'd ever seen. Best of all, it stayed hard as long as she needed and shot heavy loads of hot sticky semen. Mary loved John's penis the most, but she loved other penises too.
When she was alone, when she masturbated, Mary watched video compilations of men cumming. She'd spent hours with her favorite vibrator, watching as one cock after another shot its hot spunk. Sometimes the men were alone, desperately jerking their dicks to satisfy an insatiable urge. Sometimes the cocks erupted over women's bodies, over their faces, inside their wet holes. Sometimes the videos were of a woman and many men, cock after cock blasting ropes of white cum over her body. These last were her favorite, she wanted to be the center of attention and to feel so many strange cocks shooting their boiling seed over her large breasts. Mary wanted to be bathed in sperm and to feel it covering her body. She sometimes watched dirty movies with John, but these compilation videos she saved for herself. They were her secret. She'd be embarrassed if he knew how she craved all this cum and she was afraid he'd feel threatened.
