I come home early from running errands and accidentally interrupt you masturbating. I see that you're looking at wedgies on your laptop and offer to give myself wedgies for you instead while you continue to jerk off. I give myself shoulder wedgies, frontal and atomic wedgies. When you're close to cumming I put myself in a big atomic wedgie and give you a cum countdown. Let's keep this our little secret, don't tell your step-father.
