Butts! Butts! Butts! The company dormitory I moved into was a co-ed share house! Since there had only been women there up until now, they were wandering around in their underwear, not caring if I was there or not, and I couldn't stop getting an erection! Iori's tight <small butt>, Itsukaichi's <peachy butt> with a beautiful shape, and Yayoi's <huge butt> that makes their butts stand out erotically and lewdly are just too dangerous! I was dominated by her butts, they rubbed me, I was sandwiched between her, and I was fucked... It was a slutty harem situation that was completely to my advantage! I'm living in a reverse foursome share house with such a cute, tight, sexy-assed female colleague, and I've been sucking out my semen nonstop since the first day, so I'm worried about how long I can last...
