Pain

Heather got an angry, defiant look in her eye. “I know you can control my body, Billy, and you can make me do whatever you want me to do. But I’ll be damned if I give you control over my mind. I’ve seen who you are Billy- I know your true colors. And I’ll never- NEVER be your whore. I can take the pain.”

“Alright sis. Don’t ever say that I didn’t give you the option.” Billy mentally pushed into his sister’s mind. Physically, Heather would experience no harm. But mentally, he made it so that it would feel to her like a baseball bat was being shoved up her rectum. A baseball bat covered in spikes. He wanted her to feel like she was being split in two, and shredded apart at the same time. At least for long enough until she begged him to be his anal slut.

Billy slipped his fingers out from Heather’s ass, kneeled behind her raised ass, and positioned the head of his cock right against her little opening. He pushed forward, and her asshole buckled, but did not open. Heather winced in paid. He pushed again, again her anus resisted his intrusion, and again Heather winced.

Billy pulled back and spit a large gob of saliva onto Heather’s anus. Then he spit into his hand, lubed up his cock, and placed it back at her asshole. Then Billy grabbed hold of Heather’s hips, for leverage. This time when he pushed forward, Heather’s sphincter loosened its grip and the head of Billy’s cock slid inside.

Heather let out a shriek, and her body convulsed in pain. Billy held still for a moment, allowing Heather to regain some control.

“You sure you haven’t changed your mind, Heather?” Billy asked.

Heather just looked back at him with tear soaked eyes, and through gritted teeth replied “Fuck off.”

“I was hoping you’d say that,” Billy said with a smile. “But since we can’t have the neighbors calling the police, no more screaming from you.”

Billy pushed forward very, very slowly. He wanted to prolong the agony. He watched his cock slide in, penetrating her ass inch by inch. Heather was silently screaming and sobbing, trying to make a noise but only able to elicit a whisper.

For his part, Billy enjoyed seeing the pain and humiliation on the face of his sister, who had tormented him for so many years. But even more so, the feeling of Heather’s asshole was unbelievable. Like a super tight, super warm glove. Her sphincter clamped down on and massaged every inch of his shaft, as if it wanted to coax a load of his cum into her rectum. Her sobbing only increased the sensation, as each time she let out a sob her ass clamped down on his cock.

Finally Billy’s pelvis came to rest against Heather’s ass, his cock fully sheathed inside her rear entrance. He held still for a few moments, just enjoying the sensation. Heather tried to catch her breath, and mentally manage the pain emanating from her ass. Then Billy pulled back and started to thrust.

Slowly at first, and then faster, Billy sawed his cock in and out of her ass. Heather’s cock squeezed and caressed his cock, trying to expel the invader as her face contorted in pain and her tears soaked the sheet below her face. As much as she struggled, Heather’s body would not listed to her commands to move, change positions, run away. She couldn’t even get her hands to release her ass cheeks, still spread lewdly and invitingly for her brother.

Billy leaned forward, pressing his weight on Heather’s back, forcing her body to lie flat on the bed. Billy kneeled astride her ass, and continued pushing inside her.

Finally Heather could take it no more. “Ok, enough, enough Billy. You win,” she shouted, her voice coming out as a whisper. Billy stopped his thrusting.

“What do you mean ‘you win’?” he asked.

“Make the pain stop, please,” she begged.

“What’s in it for me if I do?” he asked, with a smile.

“Anything- anything you want,” she sobbed.

Billy leaned his body forward so that he was now laying flat on top of Heather’s back, his cock still buried in her ass and his face next to hers. He pulled back and slammed his cock home again, causing Heather to yelp in pain.

“Uh, uh sis,” Billy whispered in her ear. “You know what I want, and now I want you to beg for it.”

Heather hesitated. Again Billy thrust into her ass.

Heather closed her eyes, swallowed, and said, “Ok Billy. I want you to make me your…” She paused and took a deep breath. “You anal slut.”

“Beg me for it.”

“Please Billy,” she pleaded, “make me your anal slut!”

“You sure?”

“Yes Billy, please,” she grimaced.

Billy reached into Heather’s mind again. This time he removed all suggestions of pain, and replaced them with pure pleasure. He rerouted her nerves, so that the nerve endings in her anus connected directly to her clit, and he intensified the sensitivity. Then he increased the connection between the pleasure from getting fucked in the ass with the addiction center in her brain. From now on, the most pleasurable thing that Heather could do is to get ass fucked, and she was now wired to need it like an addict needed heroin. What’s more, Billy made sure that she needed his cock up her ass more than any other.

Billy pulled halfway out of her ass, and felt her shudder beneath him. He pulled back again, allowing his cock to pop out of her ass, and felt her shudder again. Then he slammed his way back in, pushing past her sphincter and burying himself to the hilt in one forceful push. Beneath him Heather convulsed in a small orgasm.

“Oh my god!” Heather exclaimed. “I don’t know how you did that, but that’s incredible!” Heather looked back over her shoulder at her brother. “Let me up, Billy. I want to fuck you!”

Billy released his controls over Heather’s body and rolled off of her, flopping onto his back on the bed. Heather leapt to her knees and looked around the room, noticing Dylan sitting on the plush chair in the corner, still masturbating and trying fruitlessly to get himself off.

Heather stood over Billy, grabbed his hands and pulled him up. “Come with me.” She led him by the hand over to the chair. “Get up, Dylan.” Dylan got off the chair and sat down on the edge of the bed. Heather pushed Billy down onto the chair. “You just sit still, and let me fuck you.”

Heather climbed onto Billy’s lap, her knees on either side of his body and her crotch pressing his cock against his stomach. She grabbed the back of his head and pulled his face to hers, their lips pressed against each other’s. Heather shoved her tongue into Billy’s mouth, circling his tongue, dancing over his teeth and exploring the deep warmth of his throat.

Heather broke the kiss, pulling his head back by his hair. “I feel empty, Billy. I need you inside my ass,” she told him. Heather raised her body up, leaning forward and momentarily feeding a breast to Billy’s hungry mouth. She reached down and took hold of his cock, and positioned it against her asshole. Pressing down, she was able to hold his cock perfectly positioned as she released her hand, placing both hands on Billy’s shoulders.

Then she **** her weight down on Billy, pulling her tit from his mouth and forcing the full length of his cock inside of her. Heather began bouncing up and down on Billy’s cock, each stroke giving her a little orgasm, and each orgasm constricting her anus and squeezing Billy’s cock.

Billy pawed at Heather’s tits while she bounced on top of him, and she used one hand to tweak and pull on his nipples. With her other hand, she reached behind her and cupped his balls. And once again she thrust her tongue into his mouth.

Heather rode Billy’s cock like this for a while. Then she got up, turned around, and lowered her ass onto him while facing away. Heather leaned back against Billy’s chest, her head on his shoulder, and thrust her hips up and down. Each downward thrust smacked her ass against Billy’s pelvis, and pushed Billy all the way inside her. Billy reached around Heather and with one hand he played with her tits. With his other hand, he reached down and went to work on her clit. Heather by now was in a constant state of orgasm, her body shaking like she was having a seizure.

Billy looked over at Dylan, still sitting on the bed, stroking his cock, and decided instantly to show Dylan some leniency. “Get over here, Dylan,” Billy ordered. Dylan obeyed.

“Let’s give my sis a DP,” Billy told Dylan.

Heather stopped bouncing. “What’s a DP?” she asked.

“Double penetration,” Billy explained. “It means that Dylan’s going to fuck your pussy while I’m ass fucking you.”

Heather just closed her eyes and spread her legs wider. Dylan put his cock right at the opening to Heather’s hairless snatch, and slid inside. Heather gasped, as the tightness intensified. Billy also felt Heather’s ass get tighter, each time Dylan thrust inside her. The feeling was intense, and Billy could feel the tingling in his balls. He knew he was getting close to the point of no return.

Dylan was pounding away at Heather’s poor little abused pussy like a jackhammer, each thrust stroking Billy’s cock through the thin membrane between Heather’s pussy and ass. Billy pushed into Heather’s mind, and implanted the command that as soon as Dylan came, she would have her most powerful orgasm yet. Then he pushed into Dylan’s mind and removed the block on his cumming.

Almost instantly Dylan let out a guttural moan, and his cock exploded spurt after spurt into Heather. Each ejaculation was a mixture of the pleasure of cumming with the pain of his sore, blue balls. Heather let out a shriek, and her body was wracked by an orgasms like she had never experienced before.

As Heather’s body shook and vibrated on top of Billy, and as her ass grabbed a tight hold on Billy’s cock, Billy too exploded into his sister’s ass. He pulled her hips down onto him and held her there, as he unleashed a tidal wave of spunk deep into her bowels.

Dylan was the first to stop cumming, and he collapsed backwards, falling onto Heather’s bed, gasping for breath. Heather passed out from the intensity of her orgasm, and Billy held her there for what seemed like ten minutes, as his cock continued to dump cum into her shitter.

When he finally finished cumming, Billy gave Heather a little shove forward, and she rolled onto the carpeted floor. Billy looked down at her and saw a river of cum flowing out of her puffy red pussy, and mixing with the stream of cum dribbling out of her brown hole, both collecting in a puddle underneath her.

When Billy finally caught his breath, he got up out of the chair, grabbed his clothes, and walked out of Heather’s room.
