Kicking my classmate from university

Hi, I found out a few years ago that I am sadist and I like writing about my experience, so I want to share about how I kicked my classmate in the balls in university. I am not sure if reddit is the right place for me, but I will try. Sorry for mistakes, english is not my first language.

This classmate (i think he has a crush on me) and I were studying together in a cafe and somehow we were talking about future plans and having family and kids. He said he is not sure if he wants kids, because he can't imagine meeting a woman who he wants to spend his whole life with. I think he used it as an excuse and is actually a virgin, because he was a bit nervous talking about it and was an awkward guy in general.

I recently thought about ballbusting a lot and had this fantasy of kicking a guy so hard, that it actually destroys one of his balls. So my mind went to that topic and I wanted to take advantage of this situation, so I asked him "You don't really need your balls then?". He got a bit confused about the question, but got even more nervous and awkward. I explained to him that I kicked a lot of guys in the balls since I was young and was wondering, if some of them can't have kids anymore now.

Usually you would expect him to react in a negative way somehow, but he was just sitting there not saying anything and avoiding eye contact. At this point I could feel that he has masochist tendency, so I continued. I basically interrogated him about if he has ever been kicked, what it feels like and what he is thinking right now.

He said he has never been kicked, but admitted he was curious as well, so at this point I just asked "Can I try to kick you? I want to see your reaction". We were on the top floor of the cafe, so there was noone else to see us. I could see he was thinking about it, but didn't want to admit it, so I basically grabbed his arm and made him stand up. He didn't know what to do, so at this point he just followed my orders.

I pulled him a bit away from the table and told him to open his legs. He did and so I kicked him in the balls. He bend over and made a quiet sound like ouhh. The kick wasn't that hard, so I told him I want to do it again, but properly. He said "are you crazy? why would i let you do that?", but I could see that he was actually enjoying my attention.

He was still standing there with his legs open holding his balls, but after a moment he grabbed a chair to hold to not fall down. In this moment I used this opportunity and gave hime another kick, but this time I used a lot more force. He made a loud oomph noise and immediately fell to the floor. The expression in his face was really funny, because he didn't expect this at all. He was in a lot of pain and when he looked up to me from the floor i think he had a tear in his eye. It was really funny how he is just lying on the floor of a cafe at my feet in so much pain, so I laughed a bit.

I thought we can't study anymore today, so I told him "You should pay for my coffee, because I gave you your first kicking experience", grabbed my stuff, while he was slowly getting up, said goodbye and went home.
