Still asking Sarah

You can see Sarah struggling to focus on the question as she keeps playing with her pussy. Her eyes roll back in her head, and she can't stifle a moan. "Oh god," she whimpers, loud enough for the whole class to hear it, her hand moving faster and faster beneath her jeans. "The language...it's the...umm.....nnnngh" she starts to say, her answer devolving into a filthy groan as she fingerfucks herself. The girl's free hand moves to her breast, kneading it roughly through her t-shirt. Her nipples press obviously against her top and she starts to shudder and spasm. "O-ooooh. Oh. OH AHHHH!" she squeals, cumming in her seat as the rest of the class gapes at her, all the girls glad they weren't the ones called on first.
