QI am a 22-year-old straight female. I used to babysit for a wealthy family, but their children have outgrown babysitters. The dad of this family is very into martial arts/fighting and has invited me over several times for “self-defense training.” I have accepted his invitations a few times, and it has always started off as a normal workout in their home gym—treadmill, weights, swimming laps—but he is always pretty anxious to get to the self-defense part. Often he will blindfold me and then come at me, and I must then wrestle my way out of the situation using the moves I’ve learned.

I did this a few times, Dan, but I found it a bit unsettling. However, he never touched me inappropriately. Last time we did this, he told me he wanted to see how much pain he could take. He asked me to kick him in the groin with no protection until he couldn’t take it anymore. I thought, “This is strange,” but I was curious, so I did it. He was able to take it for a surprisingly long time. I haven’t been back since, but for the last six months, he has been pestering me to come back. Recently, he suggested that we have what he calls a “competition.” He will stand there, and I will kick him in the balls—or anywhere else I want—and if he gives up, I get $150. If I give up, by getting too tired, I give him $20. His wife knows about the workouts, but he said he doesn’t want me to tell her about the fighting.

What we’ve got here is a rich guy attempting to manipulate his kids’ former babysitter into doing sex work for him—no, scratch that. What we’ve got here is a rich guy who has already manipulated his kids’ former babysitter into doing sex work for him, WKBFM, and that’s pretty fucking creepy. (Your previous workouts with the blindfolds and the wrestling and the kicking? Unpaid sex work.) Don’t get me wrong: I don’t think his ball-busting fetish is creepy. It’s extreme, as fetishes go, and there are definitely risks. But the risks are his. Paying you to kick him in the nuts doesn’t put his wife at risk (swift-kick-to-sack is not a known mode of STI transmission), it won’t take food out of his children’s mouths, and, as he presumably has all the children he wants, ball-busting-induced sterility might be a blessing/vasectomy in disguise.
