My childhood friend Mai is, to put it bluntly, a huge idiot. She sleeps through class and I've never seen her studying. It's a wonder she didn't repeat the year. One day, Mai said, "Let's compete for the score on the next test!" No way, there's no way an idiot like Mai could beat me... I didn't pay her any attention, but Mai said she had a secret plan. That is... "I read on the Internet that the more a man ejaculates, the stupider he becomes, so she's going to make me ejaculate a ton before the test!"... What? Are you serious? Or rather, you shouldn't just take the crap summary articles on such a suspicious crap site at face value... But Mai is serious. She forced me to take off my clothes, and while running her tongue over my nipples, she grabbed and stroked my dick. I couldn't help but ejaculate right away, and Mai looked satisfied. She said she was going to make me ejaculate like this and win the test. And so, a hellish, heavenly time began, where I was constantly made to cum, even while studying and eating. ※This work is about a cute and stupid childhood friend who took a stupid internet article seriously and made me cum over and over again by sucking and fucking me so that I could beat her in the next test.
