Use your tongue on her.

"Ooo, nice, Tiger," the blonde nurse coos, as you crouch down behind her to tongue at her cunt. "Oh god..." she moans loudly, stiffening almost at once and beginning to pant, her hips rolling in spasmodic little jerks.

You're obviously doing this right. Quickly her breathing turns ragged, and she starts to whine, then squeal, and finally she screams a loud, raw sound in the narrow hallway, focing her cunt back at your face and onto your tongue.

"Oh god," she says again, breathing heavily, and springs to her feet, grabbing hold of your shirt and hauling you into the room after her.

"That was great, Tiger..." she drops to her knees in front of you and works to free your cock.
