GVH-599 "Teacher, you're hard! You won't study until it goes soft!" My mischievous younger student accidentally made me hard, and then used my powerful dick against me, making me endure continuous bareback sex in a reverse cowgirl position while studying.

I became a tutor and was assigned to handle Rimachan, a Kansai-ben J-system girl who hates studying. I fell into her devilish schemes! She unconsciously teases me with panty shots, making me hard, then laughs at my dick saying, "You're all high and mighty but you're hard!". Then she says, "If it goes soft, we'll study" and rides me in a bored cowgirl position. My super-hard dick doesn't break even after ejaculating, and in the end, instead of studying, I was subjected to endless, limitless durability sex and had my cum milked non-stop! #ClassRepP
