FSDSS-833 - Even if my body breaks, I won't let go! Continuously penetrating the depths of the vagina with a standing back handle - Usui Rika

Fixing both arms of Usui Rika, a model-class proportioned woman, artificially, and repeatedly causing orgasms with a standing back - infinite Acme! Trembling like a newborn fawn, but relentlessly thrusting into the depths of the vagina with a piston, continuing to orgasm even as she collapses. She arches her back as she is pierced by her sex organ and is dominated by a sensation she has never felt before.
