I masturbated to this thread.
You should ask this girl out on a date. Get her all horned up at dinner. Have her drink a ton of wine. Go back to her place. Get her naked. Make her masturbate with her vibrator while looking at you. Keep asking her how bad she wants it. When she can't take it anymore... walk right up to her like you are going to give it to her and just say "you know I'm gay right?" Then leave!
