Chci, abys mi zakryl brýle svým spermatem

Hey there. I know I usually teach you math skills and whatnot, but I was kind of wondering

if we could do something else that might help you. See, you don't really know how to jerk

off properly, so I want to help you. I'm going to teach you math. Are you ready?

Mm-hmm.

Well, I know you really like nerds, so this is why I'm the best girl for the job.
