She was the first girlfriend I had as an amateur virgin. And finally, it was time for us to have sex for the first time! When I took her clothes off, I saw that she had a slender body with big breasts that you would never imagine from her clothes! I was so excited by her gravure idol-like figure that the sexual desire I had been building up until now exploded, and no matter how many times I ejaculated, my erection would not subside... She, who I thought was pure, was also very proactive in sex, a skilled technician, and her breasts were too soft... We had just started dating, and we had sex whenever we found a chance, from morning to night.
