i visited the house of my childhood friend who is addicted to survival games, and my groin was hit by my childhood friend's accidental shot. i couldn't get an erection because of that... when i said "if you show me your panties, i might get an erection...", when i had my childhood friend show me her panties, i fully recovered and had a full erection! my childhood friend was relieved at first, but gradually became excited by my erect dick and said, "but... well, maybe we should check if i can actually ejaculate?" and she even takes care of me until the unexpected ejaculation!
