Aaron stood outside of his roommates' door, as quiet as possible. If he strained, he could hear a little through the door: low, gentle, breathy gasps of pleasure. He could hear Kristina groaning every few seconds, and Jenn's satisfied "mmmm" in response. He listened for the creak of the bed, the wet sound of a finger in a cunt, a tongue on a clit. He pictured Kristina laying on the bed, large breasts pooled on her chest, moaning as Jenn's hair tickled her thighs. He pictured Jenn's toned body as she tongue-fucked her curvy wife, her firm ass and glistening, golden pussy wiggling slightly in the air.
His cock was throbbing against his jeans, and he placed his hand against it, afraid if he did more he'd be heard.
Kristina's moans grew louder. Afraid of being heard after she came, he retreated to his room a few steps down the hall. The door had barely closed when he started masterbating, imagining throwing open his roommates' door and striding in to slide his cock into Jenn's warm, waiting cunt as she tongue fucked her wife. He came in seconds, imagining the three of them orgasming at the same time: Kristina moaning in ecstasy as Jenn's cunt spasmed on his dick.
As his cum splattered onto the floor, he heard Kristina's orgasm through the walls.
*************************
He couldn't stop thinking about Kristina and Jenn. When one of his regular hookups came over the next day, he closed his eyes as she worshiped his cock. He imagined Kristina's hot tongue licking his balls, Kristina's adorable hands slowly stroking his shaft, Kristina's big pillowy breasts in his hand, Kristina's mouth taking his shrinking cock into her mouth and carefully cleaning off the cum, Kristina's desperate need to suck every last drop out of him.
When she asked him if she could cum, he told her to tell him about the time she fucked one of her lesbian friends. He was hard again almost instantly, and told her to keep going as he turned her over and slid into her from behind, imagining her tight pussy had never taken cock before.
When he came a second time, he had to stop himself from moaning out Kristina's name.
*************************
Things didn't get easier. When he woke up Sunday morning, he had a raging hard-on. Sighing, he got up, grabbed a towel, and headed for the shower. The bathroom door was closed, but his roommates were at church, so he went in without a second thought... only to find Kristina bent over, ass towards him, toweling off her legs. She was already reacting to the sound of the door opening, and he only caught a glimpse of her virgin (he assumed) asshole between two gorgeous cheeks, and a thatch of thick black hair over her pussy. Kristina whirled, and yelped, startled. She tried, only partially succeeding, to bring her towel up across her body to cover her large breasts as they jiggled from her sudden movement. Startled, he squeezed out a "oh my god, I'm sorry," and quickly backed out, all the while trying desperately to burn the image of her body into his brain.
He had never seen her naked. She usually dressed conservatively--bulky sweaters and jeans, and she was pretty stocky, with a round, apple-cheeked face, so he had always assumed she was fairly overweight. He was wrong--she was just incredibly curvy. Her tits were the size of cantaloupes, full, and firm. Her waist curved in beautifully, and she had a little bit of a tummy, but with defined obliques that made her look fit. Her hips flared out, complete with a gorgeous ass.
His fantasies were about to get a lot more vivid.
There was something else, too, something he'd spend days thinking about. When he opened the door, the look on her face was plain shock. But after a second, when her eyes had flickered over his naked body, and his hard cock, something else entered her eyes. It was that look, more than anything else, that he fantasized about as he thought about the encounter. Did it mean something? They had been close in the past, but never more than friends. Was there something else there?
Guilty about how much he had fantasized about the event, he tried to apologize again the next time he saw her. She laughed it off, telling him it was clearly an honest mistake, and he shouldn't worry about it. She put her hand on his arm, smiling at him, and telling him they were "just bodies, after all." He couldn't quite get into the idea that the gorgeous form he had seen in the bathroom was "just a body," but he laughed, agreed with her, and tried to move on.
But something was different after that.
The content of their conversations hadn't changed, but the body language and tone had. When he entered a room, she'd stop what she was doing. She'd stand closer, and punctuate her laughs or chiding with light touches on his arms or shoulders. He caught her eyes flickering over his body, especially when he was wearing tight fitting shirts or pants that made his bulge more visible.
In the past, she had treated his hookups with a sort of silent tolerance, but one morning, after he had had a girl over the night before, and Jenn was at work, she asked him what he got out of the women he slept with. In the past, she had largely treated his escapades in her house with a mild tolerance, so he shrugged, and told her he liked having sex with them. He expected her to drop it, but she paused, and pressed the issue. "But why them," she asked, "and not others?"
Again, he shrugged. "Most of it is chemistry. Even if it's just sex, if you don't like the person you're having sex with, it's usually not very rewarding."
She paused for a moment, glancing at the floor. "So... what makes you want to have sex with someone?"
He looked at her for a moment. Her nipples were visible through her shirt. "Wellll...," he started, "I like women who are submissive. Women who like serving me. I like sex with most people, honestly, but the best of it are women who feel grateful to be fucked-- who wanna give up the rest of their life for my cock for a few hours."
At this, she raised her eyebrows, and fixed him with her eyes. He was worried he'd said too much. But she took a breath, hesitated, and asked if he thought they liked that.
Again, he shrugged. "Some do. Some want to like it, but don't. You can usually tell. I like the ones who like it. I get to feel a sense of ownership and control for a bit, and they get to release their anxieties about what they need to be. They get to be what they are for a while. A lot of women like serving like that. Most don't want it all the time, but as an expression of a fantasy," he shrugged again, "they can get a lot out of it "
She looked at him with a skeptical expression. "A lot of women?"
