Two weeks later, I was allowed to come to Peter's house again and take a look at my wife's development. I had phoned them the previous week, but they claimed that my wife was somewhat stubborn and needed some more severe education, so I was not allowed to see her. This weekend, Peter ordered me to use some costume so that my wife couldn't recognise me. So I put on my favorite black lingerie including mini-skirt and leather mask that made me look like a transvestite. I always loved to wear this at home when wanking, and never had told my wife about it. When I reached Peter's house, Debby opened the door and led me in, ordering me to stay quiet the whole evening so that nobody, especially not my wife, would recognise me. I went to the bar and ordered a beer. Already a few couples and single men had joined the party. Soon, Peter entered the room, and he was followed by my wife on all fours. She looked amazing, as she was totally naked except black stockings and her big tits bound with white rope, so that they had become already deep red. Peter explained that that this was his new "pet" and that he wanted to prove to us how well educated she was. She was to supposed to act as "mouth whore" for the whole evening, for every man and woman who wanted to use her for a blow or piss job. Her private parts could be used for fun or pain, but no penetration was allowed into pussy or ass. Peter mentioned that these parts would be used in one of the next sessions.
At first his wife Debby stepped forward, carressing the pet's face, then her tits and finally her pussy. When my wife started moaning, Debby squeezed the left nipple of her bound breast hard. Of course my wife replied with an "ouch" but that was a mistake because she was immediately slapped into the face and told to shut up by Debby. She told the "pet" that she was only allowed to open her mouth to please other cocks or pussies or assholes. Again she fondled her pussy and after a while squeezed her other breast hard, and this time my wife didn't dare to reply. This game went on a few times, and after that Peter took over. Without a word, he put his hard cock into my wife's mouth. She immediately started to give him a very nice blowjob, her hands on her thighs and her legs widely spread; apparently this was the position that she had learned when performing a blowjob. After a whole, Peter took over control, took her head into both hands and fucked her hard into her mouth. When he came, he kept his cock deep into the pet's mouth so that she had to swallow every drop of cum.
After Peter was finished, he ordered her to please every man or woman who wanted some service.
During the following hours, my wife had to lick a lot of cocks and wet pussies, mostly on her knees while her "customers" were seated. I was amazed how much come and pussy juice she was able to drink, because she had alway refused to swallow my cum. Eventually, I took her leash and lead her to my couch. I positioned her so that her ass showed upwards and put my cock into her mouth. She started with the blowjob immediately, and I felt that she was in good training as she was eager to lick and caress my cock, even tough it must have been the 10th blowjob this evening. My wife's ass was upright, so I pointed to Debby to whip my wife's ass. She took a paddle, and at first fingered her pussy, while I grabbed her bound tits and dragged them hard. When my wife started moaning, Debby put a few hard strokes on my wife's ass which immediately turned red. My wife stopped with the blowjob to gasp for breath, so I slapped her hard into the face and told her to continue. Debby and I continued this play for a long time, always at first making my wife horny by gently rubbing her private parts and then giving her some pain as soon as she started enjoying it.
After I had come into her mouth, I allowed her to finish my beer for relaxing. Not much later, another couple approached us asking if they could use her. I nodded, and they led her away into a private chamber. I still had some more fun at the party and occasionally saw my wife again being abused by other guests. I don't think that she had recognised my cock, and if she did she was certainly too embarrassed to tell.
I left the party long after midnight, and looked forward for my next visit to take a look at the further progress of my wife's slave education!
