They were sitting on couch and talking. I sitted on chair opposite to couch. I gave him the contract and a pen, and ordered my gf to get up and take o...f her dress. She did that without asking. She was well trained. I told my client that this is very expencive and in return he can do anything he wants with her. He was stunned by the look of my gf only in her lingerie. I said that she will be his slut, slave and whore for this night. He quickly signed those papers. I smiled and took them to. She took me into the bedroom. "Put that lot on," she said pointing to apile of clothes on the bed. I went over and picked up a pair of yellowsatin panties with frills at the leg holes and a large bow on the front.Then I noticed a large hole covered in frills in the middle of the rearsection. "Oh I see you noticed the new feature - you will find out aboutthat later!"I pulled the panties up, the hole at the back aligned with the middle ofmy bottom. I shuddered to think what that was for. Next I. .. HOLLY SHIT-SHA-BOBS!" from me. "Shit!" from Joey, "See! What did I say!" from Suzi, and a "SANDI, WHAT THE FUCK?" from Brad. Sandi had a dick shaped vibrator in her ass, another in her front door, and a third which she was sucking on with vigor. Luckily I had purposely not connected any of her sexual pleasure senses to us, otherwise I know I would have overloaded. My brain would probably have first been cooked, then fried, toasted, buttered, toasted again, then would have exploded just in. "If you've got any left hunny I want it in my mouth...." she asked as she lay there, totally fucked. I got up, moved round so my cock was level with her head, laoid beside her and started to wank into her mouth. Within a few minutes, I was cumming again - several large drops of very sticky cum which mostly found their way into her mouth, but some of which stuck to her cheek and looked so horny suspended there.She lay there as we held each other in our arms. Then she took me totally by.
