18 Yo Gets Fucked at Study Hall

You are attending mandatory study hall at the college and share a table with sexy 18 year old Maxie. She is more interested in social media than writing her paper so you offer to write one for her with one condition. She needs to give you a hand job right there. She thinks you are crazy but she is liking the idea as it’s a turn on her her too. So you type up a paper and she sits on the table to give you a little preview what is coming up. Only problem is can you and her stay quiet and not get busted or is she going to scream out loud when you fuck her to the climax?
