I never really believed the saying that the best target is a girl who's not doing well with her boyfriend. I mean, I never even considered trying to get with a girl who already has a boyfriend, and I certainly didn't think I'd end up in such a situation. But then it actually happened... Even if she was my senior's girlfriend, it's hard to resist when an older, beautiful woman actively pursues you and you get an erection. I have no idea why this happened to me, but I ended up going along with it when this suddenly aroused older woman took control. Later, I found out that she had been a bit interested in me for a while and apparently came to my place thinking, "I might as well have sex with him." It's amazing how things like this can happen.
