[Toshiue Onee-san Tengoku (Erogaki Tenshi, Asahiru Yuu)] The Zookeeper Who Got Fucked by Three Goblins [mickeyj]

Ikumi has her hands full as a zookeeper whose three goblin charges can't keep their hands off her fat ass every time she steps into their cage to clean. When the director orders her to whip the mischievous trio into shape for an upcoming animal show, they escalate from sneaky groping to spying on her showering—her huge breasts and curvy body on full display—before cornering her under the running water for a relentless gangbang. What starts as a routine ecological experiment ends with Ikumi getting pumped full of goblin cum over and over.
