Preferably done in a dim dormitory lobby, a blow-job is given by a Caucasian girl. The girl is then thrust down by an African-American man upon his erect shaft. The girl then proceeds to suck him off until she realizes that she is drunk and does not to participate in this action. She quickly gets up and runs away. The man is left with blue-balls.
