Emily and me are part of a group of 3 like minded couples, all between 30 and 40, who enjoy sex together. We have get togethers at one of our houses every month or so and indulge in a weekend of sex involving some bondage and mild punishment. Emily likes to be blindfolded, cuffed or held down while all the men fuck her. While others like to be ordered to carry out various sex acts on themselves or others. The main rules are NO and STOP which mean exactly that. Whilst we enjoy our get togethers what we really look forward to is our holidays when we rent an old farmhouse, in the Lot region of France, which has about 12 acres of enclosed garden and woods. Unlike the UK it is warm enough to spend the whole holiday naked and have sex outside without being disturbed. Earlier in the year a new couple were introduced to the group, we got on well, so 8 were going to be on the holiday. We decided on a theme of Dogs and Bitches, Masters and Mistresses and purchased studded collars and leads for the girls and cockrings for the blokes to which a lead could be attached. We drove down to France in 2 cars and got ourselves sorted out and went out for meal, returning to the farmhouse at about 11pm. We'd already sorted who was sleeping with who and it would not be our own partners. I was with Olivia who I like to fuck as she has a really tight cunt. In the morning we drew cards to select the Dogs and bitches who must obey the commands of the masters and mistresses. I drew low and was a dog, which meant that Emily would be mistress to the other dog. A lead was attached to my cock and I was lead outside for a walk by my mistress. I was taken to the woods and told all good dogs need to piss when they see trees, holding my prick as I pissed against one. She tugged my lead and found a grassy area where she lay and and ordered me to lick her pussy. I lapped as she used her fingers on her clit ordering me to stick my tongue in her cunt, lick her harder, until she came. My cock was rock hard and she gave it a quick suck and stroke saying "We'd better go and find you a Bitch to mate with". She led me back to the garden, passing Emily being fucked hard by her Dog on the way. In the garden we found the two Bitches watching their Master and Mistress, fucking on the lawn. We watched as his prick entered her cunt as she wrapped her legs round him asking him to fuck her deeper, make her cum. She called out "Is it OK if my Dog mates with the Bitches?" She was told me OK and a Bitch ordered to kneel. She felt her cunt, slipping in a couple of fingers and pronounced it nice and wet and ready to be fucked. She took hold of my prick and pulled me to the Bitches cunt and ordered me to fuck her. She stood over us, holding my lead, as my prick penetrated the waiting pussy. I moved slowly, but only as far as the lead allowed. My mistress watched closely and shouted "Fuck the Bitch harder. I want to see your fucking cock make her cum". The Bitch had got into the rhythm and was moving with me as we shagged on the lawn. Her cunt tightened on my cock gripping as she came, a few more shoves I came in her. I was pulled off and my cum dripped out of her. The other Bitch was told to get underneath to lick and swallow my cum. I was told to wank my prick to fuck again, I knew it would be probably half an hour before I would get another erection and after 10 minutes she said I was taking to long and would have to be punished. I sat with the Bitches while she spoke to the others who went to find Emily and her Dog. She lead me to the veranda, standing me next to a couple of posts. She returned with handcuffs and rope, cuffing my wrists to hooks, spread my legs and tieing my ankles. She used a ball gag and called the others. She explained that I was being punished for only fucking one of the Bitches and that they needed to get me hard to finish mating. The Bitches were ordered to kiss and suck my nipples, to lick up my legs, tongue my arse and wank me until hard. My cock was beginning to respond but she decided not quick enough. She looked me in the eye and said "Your cock needs more. It needs sucking". Then added "I think I'll get the Dog to do it". She waited to see if I'd say no then called for the Dog to kneel and suck my prick. The Bitches held my cock and guided it to his mouth and they all watched as another man took my prick and began to suck me off. It obviously wasn't his first and I felt my cock swelling in his mouth as I hardened. One of the Bitches had a hand between my legs and had managed to insert two fingers in my arse. With them both working on me I was fully erect and and ready to fuck, and the other dog had enjoyed sucking me and was hard. Emily had been watching all this with a huge grin on her face as she stroked her Dogs prick. She said "Don't dogs sometimes try to fuck other dogs? Let the Dog fuck his arse." I still didn't refuse as I was bent over the table, gag removed. Emily was bent over facing me and ordered her Dog to fuck her as I felt my arsehole being lubricated by the Bitches. The Dog was led tome and I felt his prick against me. My mistress said "Fuck his arse, but try to be gentle, it's the first time he's had his arsehole fucked". I felt pressure building as he opened me up and slipped his end into me. Emily was encouraging me saying "Go on take him in your arse. I know how good it feels when you arse fuck me". There was a little discomfort as he pushed harder and he penetrated my arse. I felt him spit on his cock as he began to shaft me and one of the Bitches had been told to get under the table and suck by prick. The feeling of being sucked and arse fucked was exquisite, also being able to see Emily bent over and being fucked at the same time. My balls tightened and I came in her mouth as I felt my arse being fucked harder. He was told that he was to cum in my arse and with a few more thrusts my arse had lost it's virginity as he spurted his spunk in me. Emily had cum and was laid back on the table as she had her cunt cleaned by the other Bitch who made her cum again. We were all in need of a rest and my mistress led me to her room to get my strength back. She later told me that I would spend the night with her and that if I didn't fuck her to her satisfaction I would have to be punished again. We fucked, she was a real screamer, demanding to be taken hard, shouting loudly as she came then after pushing her cunt to my mouth to lick and swallow my own come as she came on my face. At 9am the next morning it was all change, my mistress and Emily were now Bitches and I was Master. I'd already been planning the things she would have to do and looking forward to another day of sex and play. If anyone is interested I will post a follow up story of the things we got up to another day.
