Cumming Inside For The First Time

I've recently been having sex with the girl I have been dating for a few weeks now. A few nights ago while we were going at it, she looks dead into my eyes and says "I want you to cum inside of me tonight." She has an IUD and has very much expressed how she doesn't want kids at all. I had been using a condom every time we had sex. But as soon as she said that, I knew it was coming off. I had her in doggystyle from the back, going hard as I can with her screaming for me to cum inside her. After some time passed, I finally came. She began shaking hard as she could feel me shoot my load inside of her. She couldn't stop cumming for a solid 10 minutes after I had pulled out of her as she could feel my semen begin to drip out of her pussy and onto the bed. Seeing her twitch, moan, and gasp for those 10 minutes was easily the most incredible sexual experience I've ever had. I very much am looking forward to cumming inside again very soon.
