Peter looked down at Kate, his mouth wet with her juices.
"Do you want it?" He asked, his voice low and full of desire.
"Yes!" Kate hissed, her lust rising higher as Peter ran a finger over her tormented clit. "You know I do!"
Peter leaned forward, over Kate, and took her wrists in his hands. He pressed her wrists to the pillow, just above her head. He dipped his head down and kissed her lips, gently. Kate groaned into his mouth and press herself up against him, as his hard cock slid against her eager pussy. Peter pressed forward, keeping Kate's wrists trapped above her head. His stiff prick pushed against Kate's opening, and then slowly slid into her.
"Fuck." She groaned, as she took him into herself.
Peter began to slowly fuck her, but as the volume of he moans began to increase, he took one hand and put it over her mouth, keeping both of her small wrists now trapped with one of his large hands. She nodded her head, she understood that she was being a little too loud. Peter removed the hand over her mouth, slid it over her already tiny breasts.
"You can't cum in me." Kate panted, as she felt him thrust deep inside her, over and over.
"Mmm, yeah." Peter replied, still thrusting. "I'm going to cum inside you."
"No." Kate protested, even as she felt another orgasm begin to build. "You mustn't."
"Don't you want to be a good girl?"
"Yes, but..."
"Mmm, good girls take what they're offered." Peter groaned, cutting her off.
"But..."
"You want to be a good girl?" Peter panted, thrusting as deep as he could into Kate's pussy.
Kate nodded, and moaned again, as Peter's cock rubbed against that special spot inside her.
Peter could feel his balls tense and his cock stiffened a little more.
"Oh fuck, it's so big." Kate moaned.
"I'm going to cum." Peter whispered, urgently.
"Peter, no." Kate moaned. "Not inside me."
"Fuck, I'm going to cum inside you Kate."
Kate shook her head again, begging.
Peter thrust himself as deep as he could into Kate, just as he felt his dam burst.
"Fuck." He groaned, as he felt the first shot of semen spray deep into Kate's pussy. "I'm cumming."
Kate felt Peter's cock begin to pump and it pushed her over the edge of precipice. Her climax washed over her, and she felt Peter's hand over her mouth again, but she didn't care. She'd waited years to have his cock back inside her. Granted, they'd fantasised about this over the last year, and she'd discovered that it turned her on, but she'd never thought it'd actually happen. She hadn't planned to be unprotected, and fertile, but between Peter setting the date, and her not having any need to take birth control up to now, well, it was probably inevitable. Right now, despite herself, she wrapped her legs around Peter's waist, opening herself for him as he kept pumping his cum into her. She'd be lucky if she didn't end up pregnant after this. She thought and shuddered as another wave of pleasure and excitement washed through her. Maybe she should have been more honest with Peter.

It had started innocently enough. Peter and Kate had dated for over a year, six years ago. They'd broken up, for the usual reasons, they had both been younger and such was life. They'd gotten back in contact a year or so after they parted ways, and they discovered that despite their history, neither had any animosity towards the other, so they remained in contact. Being human, and friendly, with shared history, it was almost inevitable that they ended up in bed together again. Both made it clear, after the first time, and there were to be more, though neither knew it at the time, that there were no strings to it. It just happened, they both enjoyed it and that was enough. The first time had been on Peter's birthday. The second, eight months later, had been for Kate's. They had decided that it was a suitable birthday present to give to the other. In between the birthdays, they'd sent sexually charged messages, little fantasies, pictures of themselves in various stages of undress, and videos. Twice more they'd celebrated a birthday, then Peter had met Hailey.
Hailey was five years older than Kate, five younger than Peter, and they'd clicked. After two dates, they were official. Christmas rolled around, and despite himself, Peter sent Kate an image of himself. Kate had reciprocated, and their messages had picked up where they'd left off. It had been decided that they'd only send pictures on birthdays and Christmas. That was to be it.
Peter loved Hailey, he knew it, and she loved him. He loved his life with her, made all the better when, after a year, they'd moved in together. Despite this though, Peter maintained contact with Kate, granted most of their conversations tended to be of the non-sexual variety, now and then, every month or two, there would be an extended, torrid exchange. Both Peter and Kate knew every little thing that the other enjoyed and the exchanges, when they happened, were very, very detailed. They both knew that the other masturbated while they exchanged messages, and after. Imaginary scenario after imaginary scenario would be explored, until one, or the other fell asleep.
Escalation is a fact of human nature. When one person becomes comfortable with another, they will admit to things they wouldn't with anyone else. Fetishes and kinks are no different. Freely telling another person what turns you on is a liberating experience. When the other person begins to incorporate your desires into mutual fantasising, it leads to increasingly intense usage, once both people are comfortable with it, of course. So it was, for Peter and Kate, that fantasising about sex, led to fantasising about risky sex, and from there, pregnancy. Not real pregnancy, obviously, they were separated by a phoneline and several hundred miles, but fantasy pregnancy.
It hadn't been intentional, when peter had admitted that he thought about it, but he was caught up in the moment, and he had just said it, without thinking. Afterwards, Kate and he had spoken about it. Peter had been embarrassed, but Kate knew that it had all been fantasy, it wasn't real. What had surprised Kate though, was that unknown to Peter, she had orgasmed almost immediately after reading that he wanted to fuck a baby into her. That she'd orgasmed wasn't the surprise, she had been edging on and off while they were messaging, it had been the intensity of it. Kate had gone from mildly turned on, to climaxing in a few seconds, with little warning. It had taken her a few minutes to gather herself back together after that.
Once they'd established that it was just fantasy, Peter and Kate had incorporated it into their messages. With Peter's admission of his breeding kink, Kate had confessed that she liked the idea of being controlled, something she'd never desired when they had dated. As time went on, the messages grew increasingly intense. Kate's love of being controlled led to them fantasising about Peter forcibly breeding her while she protested. They both masturbated and orgasmed during these sessions, but distance kept them both from making any foolish mistakes. It was, after all, just fantasy, and fantasy should be kept just that.

Hailey slid into bed beside Peter. He was lying on his back, eyes closed, thinking about something. She turned towards him and slid her hand up along his thigh, until she slid over his relaxed dick. It responded a little as she touched it and Peter opened his eyes, a smile on his lips.
"Hi you." He said, playfully.
"Hi yourself." She replied.
He rolled onto his side, to face her, and his hand slid up along her belly to cup one of her modest breasts. He slid his thumb over her already erect nipple and Hailey's breath caught in her throat for a moment. She encircled his now semi-erect dick with her fingers and squeezed him a little. Peter sighed in pleasure and shuffled closer to her. Their noses were almost touching now, and he could see the desire in her eyes. Peter kissed her, softly, as he switched to her other breast and tweaked that nipple too. Hailey closed her eyes for a moment, to linger in the brief flash of pleasure. She felt Peter pull her even closer, her nipples rubbing against his chest, as they kissed. She began to stroke him, as he grew hard in her hand. She loved playing with his dick. Teasing him made her so wet. It didn't matter if she was using her hand or her mouth, the moment he began to respond to her touch, she started becoming increasingly horny. She felt his hand slide over her ass and squeeze one of her ass cheeks, before sliding over her hip and down between them. It was awkward, but it felt so good to have him tease her, while she played with him.
Peter trailed kisses around her neck and down to her collar bone, before returning to her mouth, his finger continuing to tease her clit. Hailey too, maintained her teasing, as she slowly stroked Peter's eager dick. Hailey, though, was already eager, and didn't really need much teasing. Usually she enjoyed foreplay, but tonight, it wasn't required. Peter was hard and she was wet. She wanted his big cock inside her. Hailey let go of Peter's shaft, and turned around, so she was being spooned by her partner. Peter, for his part, needed no more hints, and she slid his cock between her legs, sliding against her pussy. He adjusted his angle a little and felt his tip penetrate her. A slow, easy thrust, and her opening surrendered to him. Hailey groaned in pleasure as she felt him slide into her. God, she loved feeling him inside.
"Don't come inside me." Hailey reminded Peter.
Peter kept his disappointment to himself. As much as he loved Hailey, having to pull out spoiled their lovemaking, a little. Not that he'd turn down sex if he had to pull out, it just took the shine off it a bit. He pulled Hailey close, and began to tease her clit with a finger, as he slowly thrust in and out of her. She moaned a little, as he simultaneously teased and pleased her, but she couldn't afford to let go completely. Not being able to use birth control was irritating and a source of worry. Sure, they could have used condoms, but regardless of the advertising, raw was simply better. She had been feeling horny all day, and she regarded that as worthy of caution, something associated with her most fertile days. So no, she couldn't allow herself to let go, at least not completely. Peter had generally been good about pulling out, but she knew he didn't like it, and at times he'd been forgetful. She supposed she couldn't blame him, there was nothing worse than an interrupted orgasm. If he 'forgot' it would be okay, because she'd remember to pull off him, as long as she read his signs correctly.
