Your conscience wins out

Taking one last glimpse at Green's erotic display, you **** yourself to close your window and curtains. Part of you, specifically the part tenting your boxers, really wants to watch her get herself off, or even try getting into her room. You know that's not right though. She's your best friend, and that would be a huge betrayal; you could never face her if she found out.

Instead, you roll over so that your back is facing the window and stroke your cock, thinking about what you saw and fantasizing about watching or making a move. Eventually, you tense up and cum, falling asleep in the sticky mess.
