I was surprised they all arrived and on time, they even brought the wine and beer. Karen was obviously very good at persuading her parents to do something or perhaps they were just being nosey. I didn’t know and I didn’t care, the basis of my plan was in place and I had them where I wanted them. The rest was up to me so fingers crossed.

Cynthia, Wayne and Mark had dressed quite boringly but Karen was so different. She obviously had decided that the less she could wear the happier I’d be and boy, did she make me happy. Her white top was almost shear, unbuttoned and tied below her tits, her small cleavage on display, as were her nipples trying to poke through the fine material. Her shorts were pale blue and so skin-tight her camel toe was about as extreme as any I had ever seen and her rear cheeks were cleaved beautifully. From the moment they turned up, all the family couldn’t stop staring at her, even Cynthia.

We had a good light meal and Cynthia and Wayne were feeling no pain having drunk a lot more of the alcohol than anyone else. Karen was like a cat on a hot tin roof, barely able to sit for a minute and Mark just looked as if he didn’t want to be there, very embarrassed every time I caught him looking at his sister.

I had taken every opportunity to tease Karen and lead her on from the moment she had confirmed she would sign my contract. I was making her suffer because I wouldn’t let her do anything until after we had finished the food, and that time was finally here.

I sent her to get the paperwork and a pen while her parents looked at me, clearly wondering what was going on but they didn’t say a word. She had been sitting beside me and it wasn’t until she stood up that I realised how turned on she was, her shorts looked like she had peed herself. Karen returned very quickly and sat back down, put the paper on the table and signed without a moments hesitation.

I picked up the contract, glanced at the signature and passed it to her mother, watching for her reaction and I wasn’t disappointed. Her eyes rapidly opened wide, she looked at me with her mouth wide open too stunned to say a word.

So I took the contract and passed it to her father who had quite a similar reaction as I sat there with a smirk on my face.

He eventually managed to squeak, “What does this mean? You can’t do this, I won’t allow it.”

So I quietly explained to them that as she was over eighteen she could do what she wanted and that they should perhaps have another drink and calm down because I had some more bad news for them.

After they had a chance to breathe and get some control over themselves I began to explain my ‘plan’ for their future.

“From what I have seen since I moved in and particularly yesterday it is quite clear that you need help with your relationship. You are both clearly submissive and need someone to take control, and I have decided I am the best person to do that for you. Do you know what a cuckold relationship is?” I asked.

They both shook their heads to show they didn’t, seemingly unable to speak, obviously still very shocked and confused.

So I continued, “There are a number of varid scenarios, but they all revolve around the wife being controlled by another man and the husband having only a supporting role and in this case, that other man will be me. This is what is going to happen next, both of you will go home and spend the rest of the afternoon on the Internet researching the various possibilities. You will then both wash, shave, dress appropriately, and return here promptly at seven. If I think you haven’t prepared appropriately you will be punished. If I think you haven’t dressed appropriately you will be punished. Cynthia will begin by telling me how she would like to proceed and then Wayne will have his turn. I will then decide how your future relationship will progress. Do you have any questions?”

Their complete lack of reaction was comical so I told them they had a lot to do so it would be a good idea to leave and get to work. They both dutifully stood up and left without a word.

Meanwhile, Mark had sat, rooted to his seat, his mouth open and a look of disbelief on his face. So now it was his turn.

I stood up and told them both to follow me indoors.

I took my favourite seat and, once they had both got comfortable I asked him, “Have you ever had sex and do you like girls or boys?”.

He began to splutter, stopped himself, and, after a big deep breath, informed me that he had only ever had a hand job. So I asked him if he would like a blow job and he looked at me wide-eyed for a moment before nodding his head (as if he wouldn’t like one).

I told him to stand up, put his hands behind his neck, and keep them there or I would stop it from happening, and then ordered Karen to give him his first-ever, with a warning not to swallow his cum but to keep it in her mouth. She looked at me, presumably to see if I was serious and I just pointed at the contract. The look on her face was priceless as she suddenly started to realise what she had signed up to, or perhaps it was because she had started to realise how depraved I could be.

She slowly walked over to her brother, knelt between his legs and began to lower his shorts, then looked at me again, this time with a cheesy grin before pulling his underpants down.

His cock, I would guess to be about five inches, was as expected rigid and leaking. Unlike with me yesterday she used her left hand to hold it as she began to lick around his foreskin and cock head before putting her lips to the knob end and beginning to kiss it. Very slowly, she began to push her mouth over it, gradually taking him in. This had only been going a couple of minutes and she had only about half his little cock in her mouth when he screwed his face up and very obviously started to cum. I would have to explain to him that in future it would be polite if he warned the recipient that he was about to cum but he was young and inexperienced and, as Karen had obviously coped well I decided not to punish him this time. But to his credit his hands hardly moved from behind his neck although his hips had moved forward and back a few times.

When he had finished I told her to stand up and kiss him. This was probably the most nervous I had been all day, it was a big challenge to him because I wanted him to take the cum willingly. One of my goals was for the father and son to be used as bisexual toys and the more willingly he swallowed his own cum the easier this would be accomplished. However in the end I needn’t have worried because he didn’t hesitate and soon it was clear he was also really enjoying kissing his sister.

It was time for a little chat so I ordered them to stop and both to strip before sitting down again. Mark still had his erection but at least it had stopped leaking, whereas Karen’s juice was liberally coating her thighs and it seemed like she was struggling to breath. She had obviously enjoyed her brother’s efforts.

I explained to Mark about my arrangement with his sister and that from now on she was mine and that she could expect to be doing some very interesting things, mostly things that would generally be described as perverted or disgusting, just as his parents would also be mine and performing similar acts. If he wanted, he could join her and his parents in obeying me completely or he could go home and we would carry on without him.

In a quiet, subdued voice he then asked some vague questions and I gave him some vague answers before he looked at me, paused and asked what he would have to do.

“That is easy, your private life will be owned by me, you will have to obey me completely and without hesitation. Your sex life will be mine to control with no exceptions and any transgressions will be punished severely.”

He swallowed, looked to Karen who was smiling at him, clearly willing him to agree, lowered his head and whispered “Yes”.

“That’s not good enough” I said, “I want you to tell me very clearly, in front of your sister, exactly what you want.”

He kept his head lowered, cleared his throat a couple of times and then said, “I want to do whatever you order me to do and I will obey you completely and I will accept your punishments if I fail”.

I was smiling so much, they were all mine. Time for some fun.

I told Karen to lay on her back on the floor and then ordered Mark to get her ready for me to take her virginity by licking her cunt.

He was there before I had finished talking and started licking her with a lot of enthusiasm and energy. I’m not sure she was impressed with his skill but it didn’t really matter. I knew she was ready, I just wanted to get him used to the concept of serving her and me, and it gave him something to do while I stripped.

I let him continue as I laid down beside her and started to kiss her passionately, my tongue fighting with her’s, as my left hand played with her tits, taking delight in her nipples while making sure that my legs and lower body kept touching him. After all, I didn’t want him shying away from a little male on male contact. After a few minutes I told him to stop and go and sit down and wait for his next job, clearing the way for me to start gently making love to her. Despite my plans for the way I would treat her in the future, I was determined that the first time would be as pleasant for her as possible. And as I was very unlikely to get another true maidenhead I also wanted to savour the moment as much as possible.

However she was much more eager to get started. Just as I was settling down for the long, leisurely build up she grabbed my cock and tried to pull me towards her cunt, and boy did she have a strong grip.

As this was her moment I decided to let her have her way but whispered in her ear, “You do realise that you will be punished for that later?”.

She just smiled and put her tongue back into my mouth so I gently wiped my cock head up and down her slit a few times before putting it just inside her. Savouring the warmth I asked her if she was ready to give herself to me.

Again she just smiled and nodded so I slowly began to push into her. I don’t know what other maidenheads are like but, as I pushed in and felt it against my knob, I was readying myself for a little bit of a struggle, when Karen jerked her body down, let out a little squeal, and I knew I was home.

When she had settled some I began to push as slowly as I could till my hairs were against her skin. She reached up and pulled my face in for some more tongue fencing and then I asked her if she was ready.

Another smile and then she surprised me by saying “I want you to fuck me like you want to destroy me. I want to be sore for days.” and as I pulled my cock back to begin fucking her I thought what a wonderful woman.

I put my left hand on the ground beside her head for support and put my right onto her tit. I looked into her eyes and started to squeeze, gradually getting tighter and tighter. Her face screwed up but she was still smiling so I began to twist and suddenly I felt my crotch getting sprayed as she orgasmed. Time to start pummelling her. Before she had finished cuming I slammed forward as hard as I could into her tight little snatch and began an experience I had only fantasised about before.

I glanced over at Mark and could see him pulling on his little dick as he stared wide eyed at us, so I paused in my pounding and told him to stop, It took a couple of shouts to get his attention and then I told him he could only do that if he had received my permission beforehand and as he hadn’t even had the courtesy to ask, that meant when I was finished abusing his sister I would be punishing him to make sure he remembered in the future.

He was shocked (perhaps because I hadn’t warned him earlier but hey, it’s a learning experience) but from the cunt squeezing my cock I knew his sister loved what I said.

I decided as we had been interrupted that now was as good a time as any to change position so I pulled out and got Karen onto her knees before feeding my cock back into her greedy pussy. I then wound her beautiful hair around my left hand and pulled viciously back. As I had been abusing her left tit before I reached around her and took a firm hold on the right one before treating it just the way she liked.

I had only given a couple of thrust when she started to cum again so I kept right on pounding as hard as I could. I had taken the precaution during the morning of jerking off a couple of times so I was confident I could hold out better than yesterday but it wasn’t long before I felt that old familiar feeling and knew I would soon be losing it.

I released her tit and began slapping her ass cheeks while still keeping her head pulled back and just as I felt I couldn’t hold on any longer I gave her hair an even more violent tug which made her scream, orgasm and pass out in quick succession, just as I emptied my balls deep inside her cunt.

I was exhausted and collapsed onto her immobile back, gasping for air as I slowly untangled my fingers from her hair.

As I lay there catching my breath I could feel her start to recover so I rolled to the side and kissed her lightly on the cheek and then ordered Mark to get over here and suck my cock clean. He was shocked but quickly realised that it would be a bad idea to argue and crawled over to begin his duty. I would have loved to feed him my dick but, even with his mouth being put gingerly on my cock I couldn’t get hard. I slapped his face and told him to hurry up unless he wanted to double his punishment from earlier. He looked even more shocked and then quickly set about his task.

Once he was finished with me I pointed at Karen’s messy crotch and, without any further instruction he began to clean her up as well. She just laid there letting it happen with a glorious smile on her face. I looked at her tits and realised I had badly bruised them and, for a moment regretted the damage, but then I looked at her face and decided I really enjoyed it.

I got up and fetched a drink before telling Mark to go and stand in the corner while I decided what his punishment should be. I helped Karen to her feet and we both flopped onto the sofa where she snuggled up to my side and told me that it was the most amazing experience she had ever had. Boy, did I feel ten foot tall. We settled down for a few moments of well earned rest.

After a while I asked what would be a suitable punishment for her various transgressions this morning. Knowing now how much of a pain slut she was, her response didn’t surprise me at all. I told her that caning her ass would not be any kind of punishment because she would enjoy it far too much.

I said, “I think a better punishment would be to deprive you of an orgasm for 24 hours, or perhaps 48 hours”. By her reaction I knew I had found the perfect weapon.

She started to beg for only the twenty four so I pretended to think about it and then said “As it’s your first day I’m prepared to be lenient and let you off with the 24hr no orgasm rule, but next time you will be banned for days, not hours. You have given yourself to me, I don’t expect you to misbehave.”

She promised faithfully to try very hard in the future and I just smiled.

Mark was a completely different matter. I had already decided that he was going to be caned, partly to see if he enjoyed pain like Karen, and partly because it had been a long time since I last used one and knew my arm needed to get back into it.

I therefore ordered him to bend over the arm of the sofa and told him what I was going to do. I warned him to remain there and to count the strokes, and if he moved or failed to count I would begin...
