the start of what to cum

"That's precum" he stated. "This is a special dildo. This machine will randomly make it orgasm and shoot this fluid into your open mouth. This will train that mouth of yours how to suck cock and also how to be a good little slut and swallow what you're given. And that cum you'll be swallowing, it's mine. I've been saving it just for a special little girl like you. But if you run out I have a formula I can put together that will taste the same, texture and all, so don't you worry."

Maybe I'll send you on home for the day after that, or maybe I'll be ready to take you for a test ride myself, we'll see. Either way I'll be upstairs putting together your training for the next few months. Enjoy the show."

As he said that he turned on the big screen TV in front of me, which was split into four screens. Each screen was a live feed from the cameras, showing me getting fucked from different angles. There I was...
