My mother was worried about my grades, so she decided to hire a new tutor. I wasn't keen on it at all, but the girl who showed up was a cute girl with huge breasts! What's more, Miu-sensei puts her breasts on the desk during class, and even places them on my shoulders and gives me a peek, so I can't help but be curious. Then Miu-sensei notices that I have an erection and says that if I study hard, she'll give me a "reward" with her breasts...I-Is that okay?! Is it really okay to rub, lick, and squeeze these huge breasts, and do whatever I want with them?!
