Popular AV actress Kurea Hasumi suddenly visits a boarding house where 30 single men live together—bachelors, men on work assignments away from home, virgins, and horny middle-aged guys, all gathered in one place, making it a constant hotspot. Under one roof, Kurea performs creampie after creampie on all 30 men in an almost uncut, full-length format. Riding on hard, throbbing bare cocks the moment lips meet, she unleashes filthy talk and wildly grinds her hips, aggressively milking every last drop of cum, fully showcasing the irresistible charm of big sister Kurea. A highlight scene features her laughing mischievously as she says, "Hey, what if I got pregnant? Would you panic? (laughing) You'll take responsibility, right? Yay♪"
