How my boyfriend ballbust me for first time

(I'm German, English is not my mother tongue, so sorry if there is any mistake)

This happended about two years ago, Apparently Tommy has always been into ballbusting, but I didn't know by then. We had been boyfriends for five months and we both were in the couch watching a movie when suddenly he started to touch me in a provocative manner. He started touching my abdomen, but gradually his hand went down to my crotch... I didn't mind and just let he do it.

My boyfriend's hand ended up inside my underwear, and I didn't mind either because I thought he was going for my cock, and I was pretty excited to be honest... but he totally ignored my cock and grabbed my testicles-.

I was quite uncomfortable about letting him play with them in such a... "dumb" way, but I just focused on the movie and didn't complain. Big mistake. Minutes later, he told me to spread my legs a little, and I did it. Immediately, as if that had been an invitation, he squeezed my fucking balls-...

I moaned and tried to push him, but he just laughed and told me to stay quiet and that I was being a pussy-... he said he had been thinking about "test my endurance" since a lot... fuck, he wanted to crush my fucking balls-

It sounded ridiculous to me, my nuts were already aching and he just didn't wanna put his hand away of them. However, as incredible as it may seem, after arguing for a few minutes, he ended up convincing me-... It was a kind of deal, If I endure sixty seconds of him squeezing my nuts, Tommy would let me fuck him (I was the passive one the most of the time).

Anyways, I just sighed and spread my legs. We put a timer and he just started to squeeze my cum factories-... the first thirty seconds were "easy" to endure, Tommy was only playing with my balls in a pretty rough way. It was painful, but nothing I couldn't take... but shit, in the final he began to squeeze REALLY hard. I was fighting for not let out my moans and endure it, and despite seeing me in such a vulnerable position, he dug his fuckings fingertips on my babymakers as hard as he could-.

I ended up begging him to stop, and he finally release his grab on my balls, but in spite of that, the pain was so excruciating that I was almost crying.

Anyway, I didn't win due to I only endure forty-five seconds, but he took pity on me and helped me the rest of the day to recover from the ball pain, even he gave me a blowjob as a reward-.

I had my babymakers swollen until the next day, and was the most painful thing I've ever felt on my groin until then... and well, that was my beginning into the ballbusting-, we did similar things after that and I found a taste for it, now I find it quite exciting-...

Feel free to ask me whatever you want ✌🏻
