I was suddenly called out by some girls, and waiting for me were the usual serious, studious girls and... the biggest slut in school!? "I'm going to teach these girls how to have sex now, so help me out!" the slutty girl declared, opening a sex course with me as her partner!! While the serious girls took notes around us, she lectured, "Kissing is super important," "The trick is to make the guy feel really good," and "If you wear a condom, the pleasure is cut in half!" Before I knew it, her incredible technique left my balls completely empty! ...Just when I thought it was over, starting the next day, the serious girls began inviting me for "review," saying, "About the other day... I want to try it too..." The beginning of the best school days ever, having sex with the serious girls!!
