Asian college girl anal extra credit

I know I was supposed to be in class, but dancing is a lot more fun. I didn't even hear the teacher come in. I thought I was all alone, but he caught me. Maybe if I help him to cum he won't make any problems for me? On my back in the missionary position, he slides his cock into my asshole. Not just the tip, but balls deep. He fucks me like this and I can see he really enjoys the feeling. I love it too, and I feel like I am a very lucky girl to have such a good teacher. I want to show off the 'automatic' technique I've been practicing. But first, I suck his cock to make sure it is very hard. Then, I sit on him in the cowgirl position and spin around for reverse cowgirl. I love to ride like this. He can just relax and enjoy the feeling and let me do the work. It's really fun to be the boss! I can feel his cock getting bigger and bigger inside my asshole and I know it's almost time for my treat. On my knees, he cums into my open mouth, and not a single drop is lost. Thank you, teacher!
