She enjoys being a whore

This teeny wants to finish redesigning her room,but her boyfriend's got no money for it. Being 18 y.o.,stupid and horny she agrees to fuck his rich friend for cash like a prostitute. How perverted is this? Her boyfriend stays to watch her suck another guy's cock and holds her hand while she gets fucked. She feels like a total whore at first,but the closer she gets to orgasm the more she enjoys the whole.
