When Eileen pulled out of her, his cum leaking from the tip of his cock and her creampied pussy, Ty stared at his pleasured face and toned, youthful body for what felt like hours even though it was only seconds or minutes at most. Instinctually, she ached for more. Even though she already had two babies of this handsome man inside her, she wished he would give her more. She ached to get every drop of white sperm in his balls pumped inside her, for his seed and her eggs to intertwine and make countless offspring.
She wished for both of them to be prepped to fuck more, and shivered with pleasure as she felt Eileen's body press against hers again, whimpering when his thick dark cock head kissed her clit.
Fortunately for Ty, Eileen was on the same page as her. Pumping Ty full of his cum and impregnating her twice had been hot as fuck to him, and he loved the idea of putting more babies in her. "I wanna mate you more, Ty," he breathed.
"Do it," Ty agreed. "I love getting bred by you."
"You don't mind having another baby of mine?" Eileen asked as his tip lined up with Ty's slit, their juices mingling.
"I'll have as many of your children as you can give me," Ty smiled.
Eileen saw her smile turn to moaning in pleasure as his cock hit home, and he began to thrust hard and fast, pressing her hands into the mattress while his thighs pounded away at her, giving over his motions to masculine instinct.
Under her, Ty writhed and cried out aimlessly as her lover's cock filled her up and his balls slapped at her crotch with every thrust. She clenched around him with her tight slit and felt her breasts bounce, his shaft hitting her most sensitive spots and making her pleasure continued to peak higher and higher.
It felt unreal to consider they'd ever been anything but this young man and young woman, acting on pubescent reproductive instincts, making baby after baby. They didn't want anything else, either, this felt like all that mattered in existence.
Once she felt the first stirrings of their orgasms, Ty wished for her body to produce an egg for Eileen's seed to fertilize, and felt her ovaries stir as an ovum emerged from them, floating and releasing hormones to draw a man's seed to it.
"Y-you're such a good girl," she heard Eileen pant, and she knew it was true. She was his pretty breeding toy, and she loved it. "C-cumming-" his clipped, satisfied grunts intertwined with Ty's soft moans, and thick semen began splurting from his cock, filling Ty's pussy and continuing to shoot from him so it flowed out of her messily.
Naturally the seed which had got inside Ty's depths surged towards her egg, and she saw a mental picture of his sperm wearing away at her egg until one moved inside and they conceived yet another child.
