For sex

"Because we're going to have sex in a cubicle." You tell her.

"Oh fun!" She responds, "I've never done that before."

You lead her to a cubicle and bend her over the toilet. You start unzipping your pants. She looks over her shoulder at you but you turn her head to face the wall, on which someone has written "Prof. Grey loves cock." among other dirty things about all the female members of staff, especially Emma Frost.

You slide your dick into her pussy slowly. She moans as you enter. You gently slide in and out at first, building up speed. She looks over her shoulder at you again, "Harder." She moans at you. You take her advice, turning her head back around and grabbing at handful of her red hair you pull it back as you thrust into her hard. "Oh yes!" She shouts as you start pounding her. You realize very quickly that the writing on the wall is true. She's loving every inch of you inside her. You pound her so hard she has to put the side of her face against the dirty wall, as well as her hands to stay upright.

"Oh yes, fuck me!" She shouts.
