My childhood friend Mai, who is a bit of an idiot, has a secret plan to beat me in the next test: "The more a man ejaculates, the dumber he becomes." I wondered if she had been influenced by another suspicious shitty site, but she reached for my dick without any hesitation! "I'll make you ejaculate a lot before the test, and turn your grades around♪" Using the information from the internet, I licked her nipples and gave her a handjob, then took her in my mouth and gave her a deep blowjob, and then grinded on her in cowgirl position to make her ejaculate even more! She's a total idiot at studying, but a genius at sex! She can't resist at all, even though it's an important test... Ah, it's coming again!
