So this idea came about like all my other horny ideas ( i was mega horny). I stripped naked and went up to my window and curtains (the side window facing the driveway) and would open them once in a while to reveal myself to the outside. I left the curtains open while I checked my phone (because nobody was around) and I'm standing there until I see a guy walk pass and I see this and immediately close the curtains. Damn that was a good rush though. I'm not sure if the guy saw me because I closed them so fast (lol) but it got my cock super solid which I guess was worth it hehe.
