Stefan felt Katherine grabbing onto his arms and moved her ass around as if it was too much for her to take. It was warm and moist and he was desperate to cum, so he drove it in and out faster and faster, all the while admiring the feel of her soft bouncy tits. Hearing her whimper only made him go faster; taking pleasure in knowing his cock was making her cry. When he slipped out of her, she almost pouted, but however was glad that the pain was taken away as well.
They might have walked up and asked if the young woman was okay, and certainly Hitomi might have given away her guilt and nervousness if anyone confronted her before she was finished drugging Fuyuko into submission. But this is a convention. They assume that the opaque white contact lenses have some sort of pinhole aperture in them that allows her to see, that the plastic breathing mask covering her face is merely an affectation. Perhaps a few of the people glancing at her notice the way her girlfriend is holding her close and nuzzling her hair, but apart from a bit of casual titillation from the less mature male congoers, it goes unremarked upon. The young Japanese-American woman who visited the convention to reconnect with a culture her parents left behind when she was still a child is slowly, helplessly being replaced by a mewling, horny fucktoy with an urgent need to eat the pussy of her new owner.
