I play pranks on my female friend who is napping. Although I resisted, I was surprisingly not completely unfair and became a sex friend.

We have friends who have no ulterior motives. A girl who somehow feels something when she cheats on a prank and makes erotic messes with a prank... I didn't intend to do that, but the stimulation turned into excitement and easily crossed the line of friends!? The self-centered sex that can be done because we can be friends with each other is actually erotic!! From tomorrow, the incident between a man and a woman who have become a sex friend.
