My childhood friend Mai, who is an idiot, has a secret plan to beat me in the next test: ``The more a man ejaculates, the stupider he becomes''. I was wondering if she had been influenced by another dubious compilation site, but without hesitation she reached for my dick! ``I'm going to make you ejaculate as much as possible before the test, and I'm going to reverse my grades♪'' Based on the information on the internet, I give her a hand job by licking her nipples, sucking her in her mouth, and then I grind her in cowgirl position to make her ejaculate even more! Studying is easy, but H is a genius! Even though it's before an important test, I can't resist it at all...Ah, it's happening again!
