I come over to your house. You left the doors unlocked! You're my college professor and I have some issues with my grades. You seem to be giving me an easy ride and I don't understand why, since my scores should be much lower. Eventually it comes out that you're into me, and I decide to take advantage of that. I tease you with my body and words so that I can get what I want! This turns into a blowjob and riding you, but I don't let you finish. You don't get to have what you want... until I get what I want! Riding is implied with no penetration shown to give a more exact POV as if I'm sitting on your lap.
