Valire looked at all the porn that this universes version of her apparently owned (and made). She had never voluntarily looked at porn before, she saw some in sketchy parts of the city or in message boards but it always disgusted her.
However looking at it now she felt something different. She was horny in this uncontrollable way. She'd been horny before, masturbated a few times a week, but she'd never been overcome with this urge before. Thinking about it logically she realized that with male psychology came male... desires.
She unconsciously reached into her pants and started fingering herself. When she realized what was happening she didn't know what to do. These desires make it impossible not to be horny. It was just something physical that was happening. Pretty quickly she was orgasming while looking at some degenerate bondage thing.
