“Here boy” I called and Rex bounded over and began to lap at Nina’s gaping cunt.

Before I get too far ahead, Nina has been my wife for 42 years and a true dog slut; well actually just a slut. Married at 24 I had quickly taken her on a journey of depravity that started with simply fucking, then spanking to severe pain. To reduce the amount of pain Nina agreed to be fucked by my mates then I made her include her parents then mine. Somewhere in that mix Rex had become part of her daily fuckings.

It was now time for the next test for Nina, one she probably knew was going to come at some time so I had taken time to tie her into the frame, set up the cameras and connected the live stream to her and my parents so I could persuade her to agree.

For the last 20 minutes I had been fingering Nina’s cunt making her soaking wet and now Rex would lick her to orgasm. As Rex licked I prepared the item I needed.

Nina was panting to her first orgasm and I stopped and watched. “By the end of this session you will be pleading for the one thing you would never thought you would want” I said “Oh and do say hi to your parents and mine who are watching you.” Nina looked to the screen I held up showing the two sets of parents watching.

I put the laptop down and turned to Nina holding a phone “I want you to call Sue and Tom and tell them to come over and watch you being fucked by Rex.” Nina looked at me “No, I can’t “ she said.

I turned to the side placed the phone down and picked up the leather crop I had prepared with sharp nails poking 10mm through one side. I stood behind Nina’s head and ordered Rex to his bed. I leant forward and brought the crop down onto Nina’s cunt. “Aghhh” Nina screamed. “You will call them” I repeated bringing the crop down on her right breast “Aghhh” she screamed again and I hit her left breast. Nina was gasping for air. I paused. “You want to call them?” I asked again. “I can’t” she sobbed. I turned to the camera “You seem to have a stubborn daughter Pam” I laughed. Pam smiled “hit her tits more.” I gave Nina’s tits two more hits each. Nina sobbed “Please, I can’t ask them.” I hit her cunt again. And called Rex back to lick her cunt. Nina sobs stopped as she panted harder.”Hit her tits again” my Dad called. I hit Nina’s tits another two times each as she shuddered to an orgasm. “Now call them” I commanded. “OK, OK” Nina panted. I pressed call and Sue answered “HI Dad” “Hi Mum wants to tell you something” I held the phone so Nina could talk to Sue. “Sue I need you to come home now with Tom and watch me being fucked by Rex.” “What?” Sue said. “Please, just do it” Nina sobbed. “Ok” Sue said, I will be there in a bit. I hung up and called Tom. Tom answered and Nina told him to come home as well.

Sue and Tom arrived 20 minutes later. “What the fuck is going on?” Sue asked. I led them into the lounge. “Your Mum is a slut. Over the last 18 years she has been fucked by me, my friends, your grandparents and Rex and now she wants you to see her being fucked by Rex and you can use her anyway you want to” I stood. “Come on” I said leading them into the garage where their Mum was tied with Rex still lapping at her cunt. “Oh, and say hi to your grandparents” I said pointing to the laptop.

Sue and Tom looked around and were shocked to see their grandparents naked and watching their Mum and Dad. “Hi you two” Pam said “It’s time for you to join in our family fun” she paused “if you want too, of course.” “Why don’t you both strip off” my Dad Steve suggested. Tom looked at Sue then removed his shirt and shorts his cock already rock hard stood out 10”. “Come on Sis” he laughed. Sue blushed but I walked behind her and whispered “do it or I and going to whip your Mum’s cunt red raw.” Sue slowly removed her top then her bra, her tits pert with hardening nipples, before dropping her skirt and panties revealing her shaven cunt that was dripping wet. “Looks like you’re a bit of a slut too” I said sliding my hand between my daughter’s legs and raising my wet fingers to show her brother and grandparents. I leant over to Nina “open” I said and pushed my wret fingers into her mouth “get used to the taste of your daughter” I said. “Oh fuck” I heard Tom say as he rubbed his cock and shot a load into his left hand. He looked at me and I nodded. Tom stepped forward and gave his Mum a load of cum to eat. Nina swallowed it all.

“Here boy” I called and Rex bounded over and began to lap at Nina’s gaping cunt.
