[YOMOTHUHIRASAKA, HINA*CAN (bbsacon, Hinako Yui)] Shirikan Aikou no Sodominists (Steins;Gate)

Kurisu Makise learns she's more of a masochist than she ever expected when Mayuri's relentless toys leave her gaping and cumming over and over—just in time for Okabe to walk through the lab door. From there the Future Gadget Lab descends into pure anal-fueled absurdity: Mayuri's bike-short-clad rear doubles as a 200-yen capsule machine dispensing golden UPAs while Okabe lectures her on the cruelty of life, and Ruka, accidentally dosed with a concentrated sexual solution, rides Okabe with ahegao bliss until Kurisu storms in demanding someone explain themselves. With 'divergence' scrawled across Kurisu's sheer pantyhose and every lab member proudly devoted to the backdoor cause, this Steins;Gate romp is one experiment the mad scientist never saw coming.
