Son discovers mum’s fantasy and makes it real. pt2

What my son gets as his 20th birthday present is a total surprise

My son has told me he wants another sub to play with me. I have been exchanging messages with a married lady on one of those BD/SM sites whois bored with her sex life and wants something more exciting. She is 4yrs younger than me but her pics reveal a sharply body, long legs and bigger than usual tits which I know my son will enjoy.We eventually arrange to meet at a neutral place so you can imagine my surprise w hen I see my sister wearing the yellow scarf and white top that we agreed she should wear as so I would recognise her in the crowd. My thoughts turned to the times in our growing up when she got me into so much trouble with our parents that now it’s pay back time. She resisted at first but when I explained to her that I had so much dirt in our messages I could ruin her life in so many ways she had no choice but to pick up her bags and come home with me so we can go ahead with what we had organised.
When we arrived at my house I took her straight to the shower and told her make sure her pussy is smooth, I will be inspecting you when you’re dried off. She looked good standing naked in front of me, a little embarrassed when I told he to spread her legs so I can check her fanny but that’s what I expected. I helped her put on her seamed stockings and the tight corset from her bag. Next came the stiletto high heels and collar then the chain between her ankle cuffs and her wrists cuffed behind her back. She wasn’t sure at first to be so helpless but I explained it was necessary and I do all the time. She did however put up a little resistance when it came to the gag but how much defiance do you have when you’re trying to keep your balance on 4in stiletto heels and your hands fixed behind your back so she had it stuffed into her mouth eventually. The last of her will to resist faded completely when her sister leads her to the full length mirror to see herself as a slut that is going to be presented to a total stranger to be trained as his sex toy it’s to late to back out now even if she wanted to. Ready to meet our Master bitch? I’m ashamed to admit it but i can feel my pussy getting very damp as my sister leads me out of the bedroom
The lounge room is dimly lit and Master has his back to us so my sister is still unaware of who is really in control. He holds up a hand and says “leash” and I walk her over to the chair and hand her leash to Master and take my place on my knees beside his chair. You can’t imagine the look of horror and shame on my sisters face when she discovers who is holding her leash.
“Is that you aunty Clair behind that gag? You have done well mom, she looks fucking hot mom”. The look on my sisters face is pure shame and horror for her to be seen like this by a nephew. My sister is anxiously looking around for somewhere to hide but my son yanks on the leash and assures her there is nowhere for her to go now, how can she run to in those high heels anyway. She hangs her head in defeat and the shame as her humiliation grows, he knows all her secrets so she had better do as she’s told from now on. OMG son, you broke her now she’ll do anything you want. “Is that right aunty Clair? Are you going to obey me so I don’t have to beat you for being naughty?” Yes Master, I will do as I’m told. Good girl. Undo her hands mom so she can show me her clit. Aunty could not be any redder in the face while she stands in front of me with her legs slightly spread and she holds her pussy lips apart so her clit is in full view. You certainly are a slut, aren’t you aunty Clair, touch yourself slut or do I do l flog that nice white arse of yours instead? My hand moves slowly down to my pussy for my fingers to feel for that little bud that will betray me. The humiliation of being watched while I finger myself adds a new level of excitement, I’m a slut and he hasn’t even fucked me yet. Good girl, now finger yourself but don’t you dare cum without my permission. Feels good slut? Put another finger in your cunt and show me how you fuck yourself. Get her a dildo mom, I want her to feel something bigger in her twat. That one will do mom, now shove it all in her slippery cunt so she squeals as she comes. “Do it now you fucking whore, cum for me while your sister fucks you”. Clair’s eyes roll back in head and her body shakes all over as her climax rolls over her body, a euphoria that she has never felt before now exists between her legs and she grips that dildo tighter than anything before. Her whole body convulses and shudders when her climax reaches its peak then gradually fades over several minutes but she keeps that dildo held firmly in her cunt.
“You know mom, I’ve often wondered what it would feel like to fuck aunty Clair” “well son now is a great opportunity to find out. Her cunt is nicely lubed with her own climax and she did say she hopes her Master will enjoy fucking her.” Mom helps her sister lay down on her back on the floor then holds her legs open as if to offer her own sister as a gift to her owner. You want this slut as he waves his cock in front of her face, you want me to fuck you don’t you slut? I can’t answer with big ball in my mouth so all I can do is move my arse to show him how much I wanted it. Once again I find myself degrading myself by offering my cunt with that dildo still stuck in it hoping he will take what I have to offer. He has a wicked smile as he pulls the dildo from my soaked pussy and more of my juices leak from my gaping hole and form a puddle on the floor beneath me. My empty cunt wants something to take the place where the dildo used to be and I don’t care what it is, just fill me up again please. It still comes as a shock when he drives his cock all the way into me with his first thrust but it feels so good I scream into the gag and nod my head for more. But he doesn’t go on pounding me, instead he keeps his cock buried deep in my cunt while he tells me I’m his slut now and he will use me when ever he wants me. I nod my head furiously hoping he will give me more of that cock I want so desperately now. I can hear my sister laughing at my desperation and hunger for his cock. I feel so ashamed to be so desperate but I don’t care, I need to be fucked so badly I will do any degrading act to get what I want so badly. When he decides I have suffered enough humiliation I feel his dick moving in and out of me, slowly increasing the tempo until he rams it home in my cunt and orders me to look at him while he pumps his cum into me so I know who is fucking his aunty Clair. It was pathetic to watch as this middle aged woman throws her arse around to get as much cock deep in her cunt as possible then she is allowed to enjoy her own climax which would make any porn actress envious. Auntie Clair now knows why her sister is a slave to her son and she will be too because she wants to feel this sensational orgasm again. Loosing all her self respect is a small price to pay for the best climax she has ever experienced.
