You did

"John! You did it! You actually came through for me!" Demi Lovato excitedly tells you as she walks into your office unannounced after receiving a call that she was getting the part she wanted.

"Yup, I managed to pull some strings and get you the part without even needing to get you a reading for it," you tell her, Demi hugging you, which turned into a pretty passionate kiss pretty quickly.

"MMM...MMM..." she purrs as you reach around her and unhook her bra through the black shirt she was wearing, laying her down on the couch as you began to remove the rest of her clothes.

"I told you you'd see me naked if you got the me the part," she teases you, her legs hooking into her back as she tugs at your clothes, both of you now naked in your office as Demi gets on top of you.

"If we're gonna do this, we're gonna do this right," she whispers to you as she guides her tight pussy onto your dick, "and I always LOVE being on top."

"Ride me, you sexy thing," you say to her as she begins to lift her cunt on and off of your dick, not wasting any time getting into a good rhythm, when all of a sudden, you see a shadow moving towards your unlocked door.
