Chris put his hand around the rubber studded collar encasing the base 6-inches of his 8-inch dick. The head of his dick was starting to swell already and Chris watched as the purple head grew twice it's normal size. Chris stroked along the studded sheath but found only the bulbous head could feel anything. The 1/4-inch long rubber spikes were relatively soft, but the sheath covered almost the whole shaft. The head of Chris' cock had stopped swelling but looked as though it was going to pop.
Chris pumped his fist hard and found that he could still excite himself but with slightly greater difficulty and only if he moved his fist very fast. Pumping his cock like a madman with his right hand, Chris' only thought was to find some tight cunt or ass to stick himself in and get relief. He wanted to go back and resume fucking his sister face, but with his newly studded instrument, he had to find an alternative. Chris knew that at the speed he was jerking himself off with, his fist and arm would soon become tired.
Chris followed Jeff back to where his sister Cathy was still hanging upside down on the wheel. Jeff felt the teenagers stomach. He pushed the palm of his hand against her budging abdomen hard causing Cathy to scream.
'Your sister Cathy,' Jeff spoke to Chris. 'Is a very young and beautiful girl, Chris. She has led a sheltered life till recently. Too sheltered to enjoy the experience of many different and diverse lovers. Her young cunt is small and not yet open enough to accept a real man's full length and girth.'
Cathy hung upside down staring at her brother's newly studded conk and listening to Jeff's every word. She knew something was going to happen but she couldn't guess what.
'Stretching her young pliable cunt won't be very difficult,' Jeff explained to Chris loud enough for Cathy to hear. 'I have placed a balloon into her womb and filled it with a fast hardening rubber epoxy. Your mother is undergoing the same stretching but, from the outside working in. Cathy here will be stretched from the inside out. The hardening balloon is now the size of a baseball inside her womb. The string that you see hanging out is to help with the removal of that hardening ball.'
'Nnnooooo! You can't do this to me! Nnnooooo, pleeeeese!' Cathy scream when she realized what her Uncle Jeff was saying to her brother, Chris.
'I think we better gag your sister for a while Chris,' Jeff told the boy. 'Go back to the stall and get the yellow ball gag on the shelf above the bench. Put it on you're sister's head. The rubber epoxy should be fully cured and ready to be removal by then.'
Chris left stroking his cock to follow Jeff's instructions. Coming out of the stall he saw Jeff standing in front of his mother talking to her. He walked over to his sister and started to put the ball gag on her head. Cathy was still screaming as her brother pushed the hard rubber ball into her mouth forcing it open and her tongue back toward her throat.
Deb was enjoying herself on the embedded shaft. It had worked itself all the way up inside her cunt and womb easily, now that there was no plug inside her ass. The vibrator was on half power. Jeff watched the shaft vibrate his sister's cunt lips as she writhed on the 18-inches embedded deep inside her body.
The hissing had stopped and the platform was now resting on the blocks 4-inches above the barn floor. Deb was in a world of her own as the vibrating thudded her entire frame.
Jeff however, had not installed the vibrator for Deb's pleasure. He did not have an endless amount of time to stretch Deb's cunt and womb to the size he required. The powerful vibrator was there to help the job of opening his sister's body to it's maximum.
Now that the hard rubber shaft was fully inside her body, Jeff would turn the vibrator to full. The shaft was connected under the platform to a very stiff spring. Jeff had tested the vibrator on the shaft last night. With the vibrator on high the rod moved in a 4-inch circle so fast that the top few inches were blurred beyond recognition. Inside his sister's cunt and womb, the dildo would move so fast that it would seem like it was growing thicker and thicker.
Jeff reached between his sister's legs and slid the vibrator up one notch below high. Deb jumped up on her toes, but the dildo slid up with her on the rod. Her body shook all over from the fierce vibrating in her crotch. She could feel the shaft moving inside her so fast that it seemed to be spinning. Pain returned as her cunt and cervix were forced again to expand.
Amazed, Jeff watched the amount of vibration shaking the breasts of his sister. The nipples were jumping up and down so fast that the chains attached scraped against her torso as the heavy dildo hung and pulled them against her body.
CHAPTER 15
'Shit!' Jeff shouted. 'Can't have your body full of welts for tonight.' Jeff looked around trying to think of what he could do to stop the chains from rubbing as they were pulled tight against Deb's body by the weight of the ass plug hanging between her legs.
Unable to think of anything else, Jeff picked up the ass plug that was pulling down the chains and held it so that the chains were loose. The chains stopped rubbing against Deb's body and danced loosely back and forth.
'Well I can't hold this damn thing all day!' Jeff thought to himself as he looked around for an alternative. With none in sight, Jeff lifted the plug and placed the tip back at the entrance to his sister's ass hole. Holding it in place with his left hand he slapped the base with the palm of his right hand. Again and again he hit the base until the plug was fully embedded deep inside his sister's bowels again.
Deb's cunt and ass were fully stuffed as the vibrator spun inside her. Deb hung onto the poles with all her strength trying not to fall onto the dildo. Her legs were becoming numb and week with the thudding vibrations that the shaft was sending through her frame. The burning sensation disappeared, but was replaced with pain, as the rubber shaft in her, beat against the huge plug in her ass.
Fighting the pain Deb pushed her ass backwards hard against the thudding monster in her cunt. She tried to wedge the dildo against her cunt's entrance and her cervix to stop it from beating against the plug in her ass. Deb's head dropped with relief as her inner muscles wedged the dildo in a way, that the tip stopped beating against the plug.
Jeff had left Deb and entered the stall to the left to check on Anna and her brother Bobby. Bobby had finished fucking his sister's ass and had his cock in her mouth. Anna moaned as her brother continued to instruct her on how to clean it with her tongue.
'Fuck, yes! That's it cunt! Suck it! Lick the bottom some more,' Bobby was talking to his sister in a demanding voice. 'Lick it harder you fucking dog bitch! That's it, yeah, that it. Make me cum. Harder, suck harder. Yes! I'm cumming, yes! Aaaaggghhhh!'
Anna screamed as she felt her brother grab her hair and force his cock down her throat. Bobby's cock was not as big as Rex's cock but for some reason, having a human cock in her throat was repulsive. She tried not to gag as she thought of it pumping it's luke warm sickening sperm into her stomach to mix with Rex's nectar. She felt it throb in her throat. She closed her eyes and tried to make believe it was Rex that she was sucking on, but it was no use.
Bobby looked down at ring on the base of his cock that was still sticking out of his sister's lips. His balls were throbbing trying to pump his 14-year-old sperm past the tight ring. 'Suck you bitch,' Bobby screamed as he pushed harder into his sister's mouth. 'Suck it out of me! Suck it! Suck it!' Bobby screamed louder as his balls fought for release. He pulled his cock out so that just head remained inside his sister's lips and held it there.
'Tighten your lips, bitch!' Bobby told her. 'Use your tongue and suck hard or I'll ram it down your throat again, DOG BITCH!' Bobby threatened as he pulled hard on his 12-year-old sister long hair. Bobby used her tight lips and sucking mouth and tongue to stimulate the tender head of his young cock. He fucked it in and out just past the tight lips of his sister's mouth dribbling his warm liquid juices onto her tongue.
'Swallow it, Sis,' Bobby reminded her. 'Swallow it or I'll tell Jeff.'
Finished and satisfied, Bobby pulled his cock out of his sister's cum filled mouth and stood up. He looked at his Uncle Jeff standing behind Anna. He looked down at his sister's head, still held in the stock and saw her spitting out his sperm onto the ground.
Jeff could not see Anna's head on the other side of the stock, but he heard her spiting as Bobby rose and stood above of her. Jeff smiled as he starred down at the little girl's exposed ass and shook his head. He walked to the
