Slowly, you move your ass over the nurse's head. Pushing down, you enjoy the slick feeling of the lubricated head sliding into your anus. The nurse tries to scream, but it's muffled by your flesh as her shoulders are pushed in. Soon, you get to the restraints that held the nurse down while you lubed her up. You didn't want to wait, so you undid the restraints just enough to let her slip into you more.

You were about at her hips when it started to get slow going for you, as had already crammed about half of her up your anus. When you got to her knees, you reached down and shoved the rest of her into your rectum; gasping in pleasure while moaning in fullness.
