Butt! Butt! Butt! The company dormitory I moved into was a co-ed shared house! Up until now, there were only women, so they were wandering around in their underwear, regardless of whether I was there or not, and I couldn't stop getting an erection! Iori's tight ``small butt'', Itsukaichi's beautiful shape ``peach butt'', and Yayoi's ``big butt'' that makes you want to bury your face in it.The T-back that makes the buttocks stand out in an erotic and unpleasant way is too dangerous! Being laid on her ass, being rubbed, pinched, and fucked...a slutty harem situation that is completely mine! Living in a reverse 4P share house with such a cute, tight, and erotic butt girl in a reverse 4P share house, I'm worried about how long I'll last as I've had my semen drained from the first day...
