She was the first girlfriend I had as an Amateur virgin. And finally, we had sex for the first time on a sleepover date! When I took off her clothes, I saw that she had a slim body with beautiful big breasts that you would never imagine from her clothes! I was so excited by her unexpected body that the sexual desire I had been building up for years exploded, and no matter how many times I ejaculated, I couldn't stop getting an erection...! The girl I thought was pure was actually very active when it came to sex, and even though she was slim, her breasts were too soft... We had just started dating, and we had sex whenever we found a chance, from morning to night.
