When I visited my childhood friend who is addicted to airsoft, she accidentally shot me in the crotch, and because of that, I couldn't get an erection... "Maybe I'll get an erection if you show me your panties..." she said, and when I showed her her panties, I got a full erection! At first, my childhood friend was relieved, but gradually she got excited by my erect penis and said, "But... I should make sure I can fire it properly, right?" and she even took care of me until I fired it!
