You smile, "Go lock the door, we don't want any interruptions."

Mary gleefully runs to the door, locking it, and hurrying back to you. she looks at you with eyes full of sexual hunger, awaiting you to tell her what to do.

You don't say a word as you grab Mary's hand and guide it to your cock, you close her fingers around your shaft and begin to move her petite hand up and down your hard cock. You continue to guide her for a minute before you remove your hand, letting her take control.

Mary's grip tightens slightly around your shaft, her hand moving faster as her confidence grows. She takes her other hand and cups your balls, gently massaging them. She looks up at you for approval, you smile and give a nod, She smiles back.

She kisses the tip of your cock, then she kisses lower and lower down the shaft until she reaches your balls. Mary takes one of your balls into her mouth, sucking gently. She sucks for a bit before running her tongue up your shaft.

Mary begins sucking the head of your cock, her warm wet mouth feels incredible You can feel your orgasm building. She seems to sense it too as she slowly takes more of your throbbing cock into her mouth and looks up at you, a wanting look in her eyes.

You put your hand on her and fire your hot cum into mouth. She eagerly takes it all, swallowing each load with vigor. Mary slowly removes your cock from her mouth and catches her breath. You see a bit of cum dripping out of the corner of her mouth prompting you to lick it off, and kiss her on the lips. You grab you panties and begin to slip them on.

"Wait!" Mary shouts, "I want more..."

You smile, "Me too sweetie, but you've got to get to class or people will get suspicious." You walk over to her and kiss her on the lips once again, "Don't worry, we'll do this again, I promise. Now get to class."

Mary hugs you one more time, "Thanks Ms. Longwood." and she leaves your office.
