One day a virgin guy, who is unaccustomed to dealing with girls, heads to his local convenience store andunexpectedly happens upon 3 gals from his class. Finding out that he lives nearby, the gals invite themselves over and barge into his place. No sooner than later do they start rummaging around his messy room for some entertainment. And entertainment they find... In the form of erotic mags and porno flicks! Naturally, the topic of conversation proceeds on to "How does one perform fellatio?" "If you lick like this, supposedly it feels really good for the guy." one of the gals says while licking her own finger as if it were a penis. Watching this all, the virgin guy is powerless to prevent himself from getting a rock hard boner. He tries to hide it from the gals, but his efforts are in vain...
