FSDSS-408 — My Tutor, Arina-Sensei, Whispers Dirty Words In My Ear While I'm Studying And Plays With My Nipples, So I'm Going To Get Even More Stupid... Arina Hashimoto

"It's no good, you're trembling like this even though you have a girlfriend..." Ever since my tutor, Arina-sensei, found out that I have a girlfriend, she's been whispering dirty talk to me while I'm studying, and she's been teasing my nipples the whole time. She's grinning and acting like a slut, as if she's just gotten a new toy. If this keeps up, my mind and my dick will go numb. Please help me.
