A lifelong virgin moves to Tokyo to study and lands in a share house where every other resident is a gorgeous, big-titted college girl. Instead of laughing at the awkward loser, they take his virginity and offer to turn him into a real sex machine. Morning, noon, or night, these horny roommates let him practice as much as he wants—blowjobs, riding, creampies, and all-out group sex. In just three days, even the biggest virgin can become a shameless stud. The only problem? Keeping enough cum in his balls to satisfy every last one of them!
