Training of stacy

"Which one are we using today?" a voice asked. I could hear a rustle of paper before another of the group answered.

"Stacy is getting the X-1." Came the reply.

"Wow. One key?"

"Yes."

"Don't worry Marta. Stacy here isn't soon going to forget about your blowjob any time soon!"

I wasn't sure what was happening until I felt a pair of hands grabbing my limp penis which failed to come alive even under the circumstances. The hands were working it every different way and I could tell that they were holding something else.

"Two, five and three." Said one voice.

"Got it. Here you go."

I heard the crinkling of plastic and then something cold being slipped on over my cock and balls and secured in place, the material pulling down over the head of my penis.

"This will expand a little bit." One voice explained. "But you won't have to worry about it tugging in there too long." It was clear that I had had something strapped down over my cock and secured in place but didn't understand the comment.

"Thank you Mistress." I replied.

Silence only ensued as I was handed a small box, a ribbon tied around it and one of the ladies began to escort me out of the room, leading me by the elbow.

"I hoped you enjoyed yourself Stacy. Future lessons will be a mixture of emotions, some of which won't be as pleasurable."

"Yes Mistress."

We continued through two more doors and stopped before she spoke again, taking the small box from my hands.

"We are back in the changing room. After I leave, you will remove the hood and place it back on the dresser where it was earlier. You will get undressed and place the clothes back in the top drawer like before. You will get dressed and take the three boxes with you when you leave. You'll exit this room when you're dressed and proceed down the hallway, going through the last door on the left. You will wait in the room until the other door in the room is opened and you will proceed out of the building where your ride is waiting. Do you understand?
