Ty thought of an idea he really wanted to try, but figured he should ask her about it first. "Um, Eileen?" he said. "Would you, uh... would you be OK with me making you my age? It's OK if not, obviously! I think you're really pretty at any age, I just-"
Eileen's eyes practically lit up once he said it, and she softly kissed him to calm him down and convince him to do the wish. "Of course!" she said softly, smiling. "That's such a sweet idea! I think it'd be fun to be a teen again. Go for it!"
Ty smiled shyly, and focused on Eileen's soft, naked, early middle-aged form, imagining her deaging until she was 15 like him.
An intense warmth and arousal spread through Eileen as the boy's powers again started to sculpt her according to his will. Within the space of a few seconds, year after year was peeled from her life, and she felt her body shrink subtly. She turned shorter, slimmer, less subtly ravaged by age. Ty felt more and more like her equal. At some point, she hit 25 and a particularly intense sense of change affected her- that was the year she'd had Becca. The changes of pregnancy were reversed, and she felt a new fertility about her, not virginhood but an absence of motherhood that she felt desperate to reclaim. More years were wiped off her life and she felt less mature, a sort of playfulness she'd lost sight of coming back into sharp focus. She re-entered her teens, and as she reached eighteen, soon she felt her body revert to virginity. Having had sex with people felt like a dream, something she'd never actually done. And still she continued to get younger! She'd forgotten just how horny she'd felt at this age, and after years of more mellow sexuality it came back in full force.
At last the changes finished. She looked at Ty and realized she was just like him now- they were two horny 15-year-olds desperate to fulfil their arousal. She leaned forward and kissed Ty, and felt herself leaking between her legs. "Ty," she breathed, her voice a subtly higher-pitched teenage girl's voice and her Brazilian accent more prominent after her decades in this country had reduced it. "Please fuck me."
Ty could hardly turn down a request like that. He carefully pushed her down onto the bathroom floor, and pushed his penis inside her. She grabbed his hands and gasped as her slit clenched around him, the virginal vagina still unused to a large insertion. Ty could tell her body wasn't ready for him to start thrusting, so he kissed her head, lips and neck to comfort her. After a little of this, Eileen requested breathlessly, "Can you play with my nipples, please?"
Ty reached down and carefully cupped her breasts and rubbed at their sensitive tips. She panted appreciatively and whispered, "mmm, that's good, that's really good." Ty continued the motion and her pussy slowly became more receptive to his cock.
"Is it OK if I start thrusting?" Ty asked quietly.
"I think so, yeah," Eileen replied. She felt his hardness start to withdraw from her, and then push back inside. It felt amazing. Her body was suitably loosened up and lubricated for this to be comfortable now, thankfully. The boy's pace quickened in response to his instincts, and both of them loved the sensation of the faster motions.
Eileen wrapped her arms and legs around Ty as he pounded her, his head rubbing at her G-spot and his balls slapping her ass with each thrust.
All of a sudden, a horny fantasy that Eileen hadn't thought about since she'd had Becca came back to her. Oh fuck. When she'd been a teen and a young woman, she'd had a breeding kink. Ty's hard shaft was pounding her, his head was wet with precum which was already seeping into her. The boy was gonna fill her with cum and get her pregnant. She just knew they'd have such pretty caboclo babies, a pretty mix of his skin tone and hers. Her eyes flew open for a moment and she saw Ty above her, his hips thrusting at her and his penis moving into her, and she couldn't hold back any longer.
Eileen came hard, moaning loudly as her body latched onto Ty's desperately, and the boy's body responded in kind. He groaned and she felt his cock twitch as it pumped his cum deep inside her, painting her womb with his essence. She reached up to cup Ty's cheeks and kiss him again passionately.
