Tim's taking guitar lessons from Karen, and based on her reaction, he has improved quite a bit. According to Karen, Tim is her favorite student, and Karen dutifully illustrates this by asking him to pluck not the G string, but her G-string -- the one she's wearing. Tim gets the picture once she starts playing his flute ??¦ so much that he ends up blasting his notes all over her tits. Ahh, the women are horny with the sound of music..
