[FSDSS-980] "Don't cum first" Slutty playhood friend and I both cum at the same time in this premature ejaculation improvement sex session - Momo Misono (Censored)

Finally, I, who had been living a life of being unpopular, got a girlfriend. I was able to have my first sexual experience without any problems, but I was too premature and disappointed her. If I continued like this, I would be dumped by my girlfriend, so I knelt down on the ground until my forehead was worn down and asked my slutty childhood friend Momo to be my sex practice partner to improve my premature ejaculation.
