Again you end up in a detention room. And Lilly is here again too. Luckily she's wearing panties since her jeans always show her buttcrack and usually it seems like she has no panties at all. But this time she's wearing them—a blue thong. It's not any better, it still looks hot and you can't focus. She says that she hoped to see you here again. And no worries, she's not going to tease you this time! But oh, she lied. She quickly changes her mind. She tells you how she had fun last time, and she is sure you dreamed about her ass. She wants you to stroke your cock and cum for her ass again. She starts teasing you with her thong, but since you act stubborn, she goes to the bathroom and she's back not wearing panties, only her tight jeans, and her buttcrack is now fully exposed. She tells you that you need to stroke for her or she's going to humiliate you again. Today she's gonna play nice, she's not going to tell your teacher what you're doing under your desk. You can't say no to her, so you grab your cock. You stroke while she moves her ass, and tells you how much you love that view. And you cum harder than ever before.  And after you're done... She calls the teacher again! But only to say to her that you're behaving so well today.
