82. A daring plan

Smack, smack, smack

Professor Klein gripped the sides of her hardwood desk. She was bent over the front of it with her black pencil skirt hiked up around her waist. Her boyfriend, Professor Shells, stood behind her, gripping her hips as he slid his sizable dick deeper into her. She dug her fingernails into the smooth wood as he filled her to bursting.

"Fuck Dani, did I ever tell you I love being inside of you?" Professor Shells asked as he pulled her backward.

"Ahhh, only every time we do it," Professor Klein said, taking him deeper inside of her.

She rested her head on the desk, trying to relax her muscles so he would fit easier. His dick was so big it felt like there was no end to it. 

"Well, that's just because it's true every time." 

He smacked her right butt cheek. Professor Klein bit down on her bottom lip to keep from crying out at the sudden shock of pain. 

"You're playing dirty," she called back to him.
