[Nyanko Batake (Murasaki Nyaa)] Josou Heroine Starlight Crystal ~Slime-chan no Futanari Koubi de Shasei shita~

Magical heroine Starlight Crystal thinks a little game against a slime summoner's busty mistress will be an easy win—until losing means handing over far more than pride. Drenched in aphrodisiac slime and pinned by wriggling tentacles, the crossdressing hero's protests dissolve into moans as his slender body is teased to full arousal, all while the thick-thighed dickgirl in gym bloomers watches with delight and a very noticeable bulge of her own. What follows is a relentless futanari mating that leaves both heroine and slime messily, thoroughly drained.
