she had a garden hose squirting up inside her. Dog sperm was splashing on her legs as Rex continued to pump her cunt.
Cathy tensed, and then it hit her hard. Her body jerked and spasmed out of control. Her cunt muscles squeezed the dog's cock inside her so hard that she heard Rex yelp from the pressure. Rex may have stopped but Cathy wasn't finished. She pushed hard against the invading prick and jerked her pelvis up and down, screaming one long scream into her gag for a full minute. Totally drained and exhausted from her shattering orgasm, Cathy passed out with Rex still inside her.
Jeff turned out the light to Cathy's and Rex's room. He knew Rex would continue to try and pull out of the girl while she was passed out and would eventually succeed. If he left them together for long enough, Rex would fuck the girl again and again until she was released and taken away. That was alright with Jeff. He turned his attention back to his sister.
Jeff knew that Deb's sexually heightened state was not due to any chemicals, but in fact was completely her own doing. Jeff had pumped only water into his sister's ass. No stimulants or aphrodisiacs were used. He allowed her to believe she was drugged only to overcome her dwindling reluctance. The feelings within Deb's body were entirely her own now. Believing that she was helplessly drugged only served to release her inhibitions. She was ready. She would do almost anything now.
Jeff decided to see just how badly she wanted to fuck something. Jeff walked over to the cabinet above the bench on the wall and opened the door. He found the object he was looking for and removed it from the shelf. He held it in his hand and smiled to himself. He had rarely had an opportunity to use it. The object was an exact replica of a horse's dick, a very large horse's dick. It's length was 2 foot long but the really wicked part was it's thickness. For most of it's entire length it was 3 inches in diameter and at the tip it flared out like a mushroom to 4-1/2 inches. Only a true fuck slut could manage to get it in her pussy, and then once forced in. It was painful to get out. Jeff grabbed an attachment collar for the horse dildo and screwed it into the bottom end.
Jeff approached his sister Deb from behind. He did not want her to see the size of the object just yet. Deb was screaming for someone to fuck her and still shouting obscenities regarding her daughter stealing Rex away. Jeff knelt behind his sister and attached the collar holding the dildo to the steel pipe below the platform. He adjusted the collar so that the tip of the flared end was barely touching his sister's pussy lips.
Deb screamed when she felt the dildo touch her cunt. 'Yes, yes, fuck me, fuck!' she continued to scream as she rotated her hips in a circle and moved her pussy on the flare. Deb tried to slide back but her collar attachment prevented her from doing anything except rubbing it lightly.
Deb begged her brother to fuck her. 'Jeff, please Jeff, just bring back the dog and I'll, I'll fuck his brains out. I know I can do better than that slut daughter of mine,' she insisted loudly.
'No, Sis, Rex wants your daughter right now,' Jeff taunted. 'Your not as good a dog bitch as she is!'
'Please – Jeff – pleeese. I'll do anything. Anything you want from now on, but please I'm going crazy not being able to fuck something. I need to be fucked. I need a cock filling me up. Pleeese Jeff,' Deb pleaded while rubbing herself on the tip of the dildo.
'O.K., Sis. I'll loosen your collar and let you fuck the dildo your rubbing on. I hate to see you in need like this, but if I do this for you, and you don't use the dildo to fuck yourself, I'm going to have to punish you by sewing your cunt shut. Do you understand me, Sis?'
'Yes, yes! Anything Jeff!' Deb was panting out the words. 'Please just… loosen my… collar… so… I can… ram it… in my… cunt… and show you… hat a slut… I am. Hurry Jeff… hurry… I'll show you. I'm a big slut… you'll see. A big… Dog… bitch… slut.'
Jeff smiled to himself. The training was going better than he had expected.
Jeff released the collar strap that held his sister Deb from moving backward. Deb immediately wiggled her hips and pushed back onto the dildo's flared head. She pushed again, her arms strained against the handle bars. 'Nooooo,' she screamed. It was there, right at her cunt's entrance, but she couldn't get it in. She needed it inside her cunt so badly. She turned her head to look back.
Deb saw the back end of the dildo. It looked large but not too large. The size excited her when she thought of how full it would feel. She had to get it in. With one great effort she pushed back onto the impaler with all her might. She wiggled her hips up and down at the same time she pushed. She fought the pain, thinking only of her need to be fucking something so badly.
She felt her cunt entrance slowly stretching to accommodate the intruder. She pushed harder and harder as the pain increased. She didn't care if it split open, she didn't care about the pain, her only thought was to fuck something. She had to fuck something. She had to fuck it right now!
Suddenly the flare of the horse dildo shot past the stretched entrance to her cunt and slammed against the inside of her womb. She screamed in agony from the pain at her stretched cunt entrance and from the punch inflicted inside her stomach but, within seconds she was rotating her hips on the thick impaled dildo wedged in her cunt. She moaned and grunted, as her cunt spasmed, quivering around the shaft, moving so it touched every inch of her inner womb.
The helpless mother began to make short pumping strokes while she circled her hips. The incredible mixture of pain and pleasure took control of her mind and shut out all other concern's Deb had. She thought only of the feelings coursing through her loins. She couldn't stop. Her strokes along the invader were increasing in length now. She pumped harder and screamed every time she slammed the flared head of the cock into her insides.
Her brother Jeff watched as the entrance to her cunt squeezed and shrank tight around the 3 inch shaft of the dildo. With every stroke Deb made along the veined replica of the horse cock, her sensitive inner womb rolled partly in and out as though it was attached somehow to the surface of dick.
Deb's inner womb was being stretched in order to accommodate more and more length of the 2 foot long cock. Her cunt couldn't get enough. Further and further she forced it's length into her elongating sex.
Jeff watched, as his sister pulled forward off the shaft leaving the juice from her pussy along 10 inches of the exposed cock. He unzipped his pants, removed his clothes and walked over to straddled the 2 foot long cock. He looked down at his sister's ass riding along half the black dildo's length. He stroked his cock as he watched the lurid scene below.
When Jeff's cock reached it's full length he lowered himself down so that his balls rested unused end of the long dildo. He slid forward until the tip of his cock touched his sister's puckered hole.
The feeling of her brother's cock against her unprotected ass shocked Deb at first and then worried her. She stopped her movements and paused with 6 inches of the dildo in her cunt not knowing weather to move or not.
Jeff slid forward and positioned his cock at the puckered entrance to his sister's ass hole. Deb wiggled left and right against the soothe round head of her brother's prick. 'Yessss!' Deb shouted suddenly wanting her brother's cock in her ass. 'Just hold it right there. I want to push back on it slowly.'
Deb pushed back increasingly hard as her brother held his cock from moving away. 'Arghhhhhhh,' she shouted as her brother's cock slipped past the entrance and was engulfed by her tight spherical ass ring.
Deb was so stuffed that she could barely move on the shafts that invaded both her holes. She struggled to move back and then struggled to move forward, but nothing happened. Jeff grabbed his sister by her hips and pulled his body up forcing his cock into her ass further. Only 6 inches slid in before Jeff could feel the flare of the horse dildo stopping his entrance.
Jeff then slid out and back in knocking against the flare each time. His pace increased as his sister remained wedged on the large shank sticking in her cunt. Jeff could feel the heat rising in his balls as they rubbed along the length of the long black rubber pole. He quickened his pumping and, within the tight the walls of his sister's ass, he started to cum.
Her brother's sperm acted like a lubricant in her ass and Deb screamed as her brother began banging his cock in and out rapidly. His speed increased by the lubrication let him slip past the flair of the dildo inside Deb's cunt. Large amounts of sperm sprayed out with every inward pump. Some of it dripped down onto the dildo in her cunt as her ass became full and could handle no more. She tried again to move on the shafts imbedded in her cunt but could only managed to shove it in another inch. She whimpered in frustration. She needed to cum like her brother. She felt cheated that she couldn't move, and she needed to move to cum.
Jeff withdrew from his sister's ass and walked to her face. He grabbed the collar around her neck and pulled her forward. The flare of the horse dildo kept her from returning forward all the way to the same position as before and Jeff had to adjust the chin support to clip her collar.
