On her ass?

"Here it cums!" you groan and grunt as you pull your cock out of the nurse's asshole and begin to jack it off over her ass. You shoot your hot cum on Nurse Bazooms' ass. She squeals with delight as you cover her ass with your jizz. You cum long and hard and then finally sit down, exhausted.

Nurse Bazooms turns around and smiles at you.

"Well," she says. "You seem to be very healthy. Just go home and take an antacid and I'm sure you will be just fine." She wipes some cum from her ass with her hand and then licks it off, lifting her eyebrows at you.

"And come back to see me any time," she smiles.
