Fuck her ass?

You pull out of Nurse Bazooms' pussy and press your slick cock head up against her puckered asshole.

"Oh! Wait!" she reaches over her desk and grabs a tube. She hands it to you. "Use this."

You squeeze some lube onto your cock and rub it in then finger a little onto her asshole, then you press your cock head against it again and it slides in. You slowly slide your lubed cock all the way into her ass and she squeals with delight. It's so tight!

You grab her hips and begin to fuck her ass. Her asshole is so tight and grips you cock so nicely that you feel your cum building within seconds.
