Ano Yoru ni Michizure

Kotaro's a friendly, positive nightclub host with good looks. One day, a customer disappears after coming to his club, and a scary man locks Kotaro up as a result!! Kaoru, his guard, takes his virginity in a bid to force him to confess where the missing woman has gone.

Despite his sullen poker face, Kaoru's a real stud, threatening Kotaro with more unbearable pleasure if he doesn't talk the next day. Worse, Kotaro's happy life will surely end when Kaoru's boss returns from a trip in a week... and he's desperate to get away before then!!
