Ty couldn't help but think of what he and Eileen had been doing. Making sure his door was locked, he pulled off his jeans and underwear, lay on his bed and stroked himself, picturing her beautiful bronzed body.
It felt different having actually seen her naked body and made love to her. His memory of how he'd seen her big soft breasts jiggle while he'd pounded in and out of her, how her soft flesh had felt against his firm touch, intensified the fantasy. He stroked his cock harder and faster, more arousal surged through his system. He couldn't tell if the fantasy felt more intense because of his power or because he'd gotten to act on it, but either way, this felt amazing.
His eyes flitted open and saw him rubbing himself, and when they shut again his mind went to Eileen's cock. He recalled how Eileen had pinned her down, thrust himself into her and gotten her pregnant. His intense scent and hard shaft swam through his head, and he stroked himself faster still, his head dripping with precum. It surprised him how much Eileen's greater size aroused him.
The barriers of gender and sexuality seemed to melt away into desire. Ty imagined fucking Eileen the woman. Ty imagined Eileen the man fucking her. He imagined them as two men, frotting their penises together and fucking each other's tight holes. She imagined them as two women, sucking each other's breasts and fingering each other's pussies. Sucking Eileen's cock. Eating Eileen's pussy. Having Eileen's fertile sperm knock her up. His fertile sperm getting to knock Eileen up.
"Eileen, Eileen, Eileen, Eileeeen..." He groaned the MILF's name as he came hard, squirting his thick white seed onto himself messily. Fuck, his desire for the mom next door was way more intense than he'd thought. He wondered what fantasy to wish would come true most, or at least first...
