MIAA-105 If I can't solve a big-ass teacher's problem, I'll be f** to fire my grades in supplementary lessons... Yu Shinoda

I end up masturbating during class because my head is full of erotic things, so my serious teacher decided to give me a very special supplementary lesson to ``make me feel refreshed and improve my efficiency'' during summer vacation! - ``If you're horny and can't concentrate, you have no choice but to ejaculate, right?'' In order to clean the testicles more perfectly, she induces horniness by grinding her big ass and sitting on her face, plays with her nipples in cowgirl position, and straddles herself covered in lotion to increase her pleasure! - No matter how many times you ejaculate, it won't end, a student-oriented bittan bittan pile driving instruction!
