Comic adaptation of the audio voice drama "Earnest 32 Year-old Virgin's First Time".

You meet up with your female coworkers for a night out, and the conversation shifts to a 32 year-old guy at the company who is rumored to still be a virgin. Everyone decides to do a punishment game where the loser has to seduce him, and find out if the rumor is really true, and, just your luck, you lose. You try to pass it off as a joke, and change the subject, but the women won't let it slide, so you really end up having to go out with him...
