Study sesh turns to panty tease

I love having you as a study buddy but why do you always have to get me so turned on?! I can’t concentrate. I try on my new panties for you because I love making your cock hard. I can always see it rising in your jeans and it gets me so wet. Watch me try on my panties and smack my ass while I twerk for you. Maybe, if I ace this test I’ll sit on your face.
