Student hides her passion behind the guise of modesty and lets her boyfriend corrupt her

Sweetie Fox, a girl, prepares for her exams by putting on her glasses to scrupulously reread every phrase in the book.

He shows the girl's cock and then she shows a different side of her personality as she greedily sucks him, asking for sex.
