"Well well, isn't this nice?" you say, leaning on the nurse, pinning her to the bench as your semi-flacid shaft pulses inside her. "Though I can think of somewhere nicer."
"Wha?" the nurse says, then is shut up as your hand fastens over her mouth. Using that leverage you pull her head back towards you and open wide. You are going to feed well tonight!
The nurses eyes go wide as she sees where she is heading, then your lips slurp around her head. You grasp her upper arms, holding her in place as you wriggle down, pressing your lips down her neck and in under her dress.
You force your way into her nurse top, tearing it up as it goes around your head, filled as it is with the nurse's already. Her shoulders slide in a treat and soon you are packing away those mighty mammaries you admired earlier.
You grin around her as they fold in under your upper lip, teeth scraping across the tender skin till the whole masses plop in. Now your lips hold her arms in place you leg go there and rip the remains of her uniform off her, then her undies (she thankfully didn't wear a bra. Very considerate of her!).
