Around 6 years ago, I was hooking up with a girl I had met online. We had been seeing fir a little while, so there was alot of built up desire.we met in a hotel, and git down to it. Eventually she got on top and started to ride my dick. She had an amazing pair of titties and tge sight of her on top of me, her face gripped with pleasure really turned me on. I started grabbing her ass with both hands as she grinded. I Eventually got so turned on, I went to slap her ass check as hard as I could from the bottom/being rode position,but as she bounced, and in my horny haste, I missed completely and nailed both balls with near all my strength. After the usual 2 second delay. The pain made me ask her to stop riding. She was confused at first, then realized what happened. Sooo embarrassing
