Shiki looks like a gentle, ordinary adult college student, but she is secretly a ruthless dominatrix. She lures men through an app and brings them to her training room for total sexual control. Sometimes she pounds them mercilessly with a strap-on; other times she pushes their sensitivity so far that they release astonishing amounts of male fluid. Treating every man as her toy, she binds them in bondage gear, forces prostate orgasms, then uses her pussy to milk their cocks until their balls are empty and she is filled with semen.
