Walk through the door

I stood up and tried to stop thinking about jerking off, I walked to the door and looked back to my mom. "I'll be running some errands, I'll be back by the time you get out" she said waving as she walked away, I turned back to the desk lady at the door, I walked through and looked down the hall.

"You'll be in room 12!" She said after glancing at her clipboard. I started to walk down the hall looking at each door, when I finally got to room 12 the door was closed.
