Cumming on my teacher's big booty (with Mellanie Monroe)

It is no secret why you are in your teacher's office today. Miss Monroe intercepted a note you wrote to a classmate saying that you want to do something very nasty to her. Luckily for you, your teacher is amenable to not calling your parents. Since you seem to want to cum on a big ass, Miss Monroe offers hers up for your amusement. She tells you to take your dick out and stroke it. This is even better than if your classmate had gotten your note because you have had a crush on Miss Monroe for years. She stands up and exposes her big breasts to you. They are so full and plump that you wish she would let you put your dick between them. As Miss Monroe slides her skirt over her big ass, you really appreciate what a fine specimen she is. You are invited to put your dick against her ass and that makes her pussy nice and wet. You hear the wetness when her fingers work over her pussy. "You're making my pussy wet as fuck," she whispers to you as she moves her finger in and out of her pussy.
