STAR-710 - I can't resist my friend's sister's juicy ass... Dangerous fantasies sparked by her accidental exposure

I'm losing my mind over my childhood friend's sister's incredible curves and constant accidental panty flashes. We're here for a study session, but she's walking around in such revealing clothes, clearly not seeing me as a man. My head is filled with dirty thoughts, and I finally snap—grabbing her ass, spanking her, and indulging in every twisted fantasy I've ever had about her.
