We're really good friends and I let you borrow my flash drive to brush up on some notes that you missed from class. While you are studying you click around and see what else I've stored on the drive and find some video footage of me fucking around with another guy that doesn't look like my current boyfriend. I must've forgotten to remove the videos before I gave you the drive. After you've gotten all the information from class, you come into my dorm room to give the drive back to me. You tell me what you've found and threaten to tell my boyfriend that I've been cheating if I don't give you a titfuck. I really don't want my boyfriend to break up with me so I agree. I take off my top and show you my super tight sports bra. You titfuck my massive cleavage in the bra until you cum. I think we're done but you're still hard and say you can go again. I take off the bra and show you my gigantic tits. I let you titfuck me again really hard until you spray another huge load of cum all over my big tits. Then I tell you that we can do this again just as long as you promise not to tell my boyfriend what a huge slut I am ;-)
