Unsatisfied with her boyfriend, a friend's girlfriend confessed her desire to cheat, so we decided to try a remote-controlled vibrator with her on a deserted rooftop. Watching her struggle to suppress her moans as she got turned on, I felt guilty toward my friend—but still ended up fully erect. When we returned to the room, I became determined to thoroughly pleasure her, making up for what her boyfriend failed to give her. She was beautiful and highly sensitive, and my excitement overwhelmed any guilt I felt. Though a trace of remorse remained, I couldn't control myself and ended up giving her a generous creampie.
