Butt! Butt! Butt! The company dormitory I moved into was a co-ed shared house! Up until now, there were only women, so I couldn't stop getting an erection because I was wandering around in my underwear, regardless of whether I was there or not! Iori's tight ``small butt'', Itsukaichi's beautiful shape ``peach butt'', Yayoi's ``big butt'' that makes you want to bury your face in it, and the T-back that makes her 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 sexy co-worker girl, I'm worried about how long I'll last as I've had my semen drained from the first day...
