explained with a smile to Anna.
Deb felt the familiar burning at the entrance to her puckered ass, as her 12-year-old daughter applied a glob of goop to her ass hole with the end of the rubber dildo. Deb's cunt and womb were still extremely open from her daughter's last application. No matter how much she tried to squeeze them they wouldn't close. They seamed to be hardened in their extremely open position. The pleasant burning was still there, but she craved for something to fill the unbearable emptiness.
Anna pushed the tip of the dildo into her mother's opening ass. She raised her elbow level with the dildo and rammed it forward with the heal of her hand. It sank instantly into her mother's ass about 6 inches. Anna swirled it around before pulling it completely out again. She dipped the end into the jar of gob and wiped the large glob into her mom's ass, filling it with jelly like substance. She stuck the tip of the dildo back in the jar and proceeded to pack her mother's ass full.
Deb's ass opened allowing more and more of the substance to be packed inside. She felt her daughter filling her cavity with what seemed an enormous amount of the jelly. Just then she felt the dildo slide into her ass effortlessly only to be pulled out as easily as it was inserted. Deb realized her open bowels were now exposed to the world. She felt the cold barn air pass up inside her ass, cunt, and womb unrestricted.
Once again she felt something in her ass but she could barely feel it touch the walls of her bowels. The dildo was removed and this time she felt something barely touch the open ring to her ass. 'Oh NO!' she thought. 'My holes are so big I can't feel anything inside me!'
Anna continued to pack her mother's ass until the jar of gob was empty. She looked at her mother's holes and giggled at what she had done. 'Wow, Mom, you're so big, you could fit two horse cocks in your ass now,' Anna snickered at the sight of her mother's enlarged openings.
Jeff walked around to where little Anna was standing and looked at the empty jar and the gloating child. It was true, Deb's ass and cunt were open so much she wouldn't be able to feel anything unless it was very deep inside her ass or womb.
Jeff walked over and turned on the hose and walked back to Anna standing at her mother's ass. 'I think we better clean the glop we can out of her with this. Stand back when you turn it on and don't splash any on yourself.' Anna backed up about two feet, turned on the hose and flooded her mother's openings with the stream.
After a few minutes Anna moved forward and stuck the nozzle into her mother's ass and watched as the water poured out of the opening. She then stuck the nozzle in her mother's cunt and did the same. Satisfied that she had cleaned everything out, Anna turned off the hose and dropped it to stare inside her mother's backside. She put her fingers at the opening and slipped them inside. If she was careful she found that she could put her arm in about 6 inches without touching anything at all. Anna ran her hand around the inside of her mother's cunt and then put her other hand inside her mother's ass.
Deb moaned when she felt the sensations of something touching inside both her holes. She tried desperately to close her holes around her daughter's arms and hands but couldn't.
Jeff looked at Deb's condition and shook his head. 'Well Deb, it looks like your not going to get to fuck the dog after all. I don't even think you'd feel much if the dog fucked you in either of your holes right now,' Jeff explained as he looked at his sisters enlarged ass hole.
Jeff walked up to where Deb was sucking on her daughter's ass and pulled Cathy away from her mother's hungry mouth. Deb turned her head to the side and screamed at her youngest daughter Anna.
'Anna you little fucking cunt. Just wait till I get hold of you,' Deb screamed as loud as she could. 'You won't be a virgin anymore when I'm done with you! How could you do this to me? You know how bad I need to have Rex fuck me, and look at what you've done. You'll pay for this you little whore. You'll pay big time!'
Jeff unstrapped Deb from the platform and helped her up while she continued to scream at her 12-year-old daughter. Deb's legs refused to stay under her after being on the gurney for over two hours. Jeff helped her over to one of the posts and sat her down.
Deb winced as she sat on her extremely open ass hole. And rolled to her left ass cheek for comfort. Jeff clipped her left wrist to the pole and walked back to where he left Cathy and Anna.
Jeff brought two bails of hay in front of where Deb was now sitting attached to the post. He lifted one of the bails and slipped a piece of rope with a loop at each end under the hay. He threw a horse blanket over the bails and walked over to unchain oldest boy Chris. Jeff brought him back and sat him on the blanket-covered hay. He pushed Chris on to his back and attached each hand to the rope stretched under the bails.
He walked back to Cathy, pulled her up and brought her over to her brother. He helped the girl kneel on the hay straddling her brother's body once again. He pulled Cathy's ass back till her brother's cock was held straight up between her ass cheeks. He pushed Cathy's head down until it rested on her brother's chest. Cathy instinctively started stroking crotch up and down the length of her brother's cock.
Jeff turned to Anna and shouted. 'Anna, open the third stall, get Rex and bring him here,' Jeff instructed the girl. Anna ran down the isle looking into each stall until she came to the third one and stopped. She opened the gate and slipped her hand under the dog's collar.
Anna had to almost run as Rex pulled her along to be by Jeff's side. 'Thank you Anna,' Jeff said as he fastened a leash to Rex's collar. 'Kneel down Anna and lick the dog's cock till it's nice and hard. Take your hand and gently hold his balls as you lick him. Don't hurt him or he might snap at you.'
Without hesitation Anna dropped to the dog's underside, reached towards his sheathed prick and while holding it gently began to lick the tip of his prick.
Deb watched what was happening in front of her and started shouting at Jeff. 'She shouldn't be allowed to suck Rex's cock after what she did to me,' Deb shouted at Jeff and her daughter, 'Bring Rex over here and I'll show you how a real slut sucks dog cock. Let me suck it and feel it slide in and out of my mouth. Look it's getting so big she can't even get her mouth around it. Let me do it. Get her away for him.'
'Alright Anna that's a good job,' Jeff said looking at the dog's fully extended cock. He looked up at Cathy's moving ass and saw that she had already managed to get her brother's cock inside her pussy. Jeff led Rex forward to just behind exposed moving ass the beautiful 16-year-old girl. 'Rex lick,' Jeff said.
Rex proceeded to lick Cathy's ass and her brother's cock buried inside her cunt. Both the teenagers stopped their movements to let the dog lick them. Rex moved his tongue up from Jeff's balls to Cathy's ass and darted it in and out of the still stretched opening. Cathy trembled as she visualized what she hoped would come next. Keeping her ass still she flung her hair from side to side and screamed with pleasure.
Cathy suddenly remembered the words she had heard before. 'Rex. Fuck!' she screamed. Rex was more than ready and leaped up and rapped his front paws around Cathy's waist. Rex started jabbing trying to find the opening that his thick doggy cock needed so badly.
Rex knew only that soon he would satisfy himself on this human girl bitch. He pumped his hips forward towards the opening he knew would be there. Instinctively he jabbed his prick searching with the tip of his engorged cock for the opening. Suddenly he felt a hand encase his cock and lift it gently and he humped. He felt the tip of his cock strike home. He squeezed the girl bitch with his front legs, hunched his back and drove with all his might. With each thrust he could feel his cock moving further inside his bitch.
Something inside Rex took over and his muscles worked together towards their final objective, to slam the entire length inside the girl bitch's hole. To feel the base of his cock surrounded by the ring of the tight opening. To feel the bitch milking his cock with every stroke. To plant his seed as far inside as he could. He pumped furiously while squeezing his bitch with his front legs.
Anna had decided to help Rex find the opening of her sister's ass as she sat on the ground beside him. She watched with amazement as Rex's cock continued to grow and become extremely fat in the middle. Anna now watched and listened to her sister's moans as Rex drove into her like a jackhammer.
Cathy was in heaven. With her brother's cock in her pussy and the dog's cock in her ass she was so tight that every movement brought pleasure to her entire body. She rubbed her breasts on her brother's chest and let the dog pound her ass with his magnificent cock. She felt her brother squirting in her pussy and moaned as his hot seed spread its warmth to every inch of her being.
Cathy felt those glorious sensations starting deep within her thighs. They continued to build until her body could no longer wait. She jerked and piston her cunt against the dog's cock in her ass. She scooted back and forth on her brother's cock in time with Rex's thrusts.
Rex pressed forward and held his cock all the way in her ass. Cathy felt Rex's cock pulse as he flooded her bowels with his hot cum. She felt Rex's cum leak from her tight ass and run down around her brother's cock and
