My friend Rika is usually pure and gentle, easy to talk to, so we occasionally go out drinking together. I've always noticed that her personality completely changes when she drinks—she becomes aggressive. That day, she clearly drank too much, and I couldn't just leave her, so I decided to walk her home. Suddenly, the drunken Rika kicked me down and shouted, "You're turned on just looking at my panties, aren't you? I'll check for myself!" Then she pressed her legs against my crotch, saying, "I'm going to give you the electric massage punishment." When I replied, "Looks like I really am hard," she straddled me, pinned my hands down, and began a full-on electric massage, claiming she'd crush my balls. Even while drunk, she took full advantage of my erection, doing whatever she wanted as I was helplessly brought to climax in the most humiliating way.
