Watching your classmate, you have smutty fantasies about her....
Without paying attention to the people around you, you immerse yourself in your fantasy world.
In this world, it seems that you know some secret of hers.
Provided you don't tell anyone, she agrees to any kind of play with her mouth...
I agree to do it with my mouth, so please don't tell anyone about what happened last time, please!
...Yes, I won't run away, even if it hurts from the cock penetrating my throat.... Good. I'll drink everything you pour into my mouth.
I realized that if I can't swallow it all... You'll tell me everything that happened last time..........
