The drive across town was nightmarish. He tried to concentrate on driving but he kept hearing the sound his sister made as she came replaying over and over in his head. He considered just pulling over to the side of the road and quickly relieving some of the pressure that was building but he knew to do that he would be risking getting arrested. By the time that Nate arrived at her door Claire was already a bit agitated.

“What took you so fucking long?” She whined.

“Traffic.” He said as he pushed past her.

They did not bother with pleasantries. Their relationship was purely a physical one. Neither of them wanted to deal with the emotional entanglements of a real relationship so it was the perfect arrangement. There was something different about the way he looked at her this time. There was a hunger that she had not seen in him before. His hand reached for the fuzzy black belt that held her robe closed. The loose knot that it was tied in came undone with a single tug leaving her robe to fall open and reveal her nearly naked body. His gaze moved slowly from her face down to her ample breasts and finally to the lacy crimson thong that covered her freshly shaven mound.

He was surprised by how much alike her and Kayla’s bodies were. Claire let the robe slip from her shoulders and drop to the floor. The devilish grin that formed on his lips said he was more than ready to have his way with her. She smiled and turned to walk toward the bedroom but he reached out and gently grabbed her arm, leading her to the sofa. He did not stop to undress. Instead he just gently pushed her back onto the sofa. She laid back and licked her lips as he knelt down in front of her. His fingers slipped under the edges of her panties. Nate slowly peeled them down. She was already quite wet. His hands slid up her silken thighs and parted them widely for him.

When he looked at her, all he could see was his sister’s naked body sprawled out before him.  She gasped loudly as his tongue slipped between her thin pink lips. It had been quite some time since he had taken the time to go down on her like that. His nose nudged her clit as his tongue tried to probe further inside her. The sounds of her delight filled the room as he licked faster.  As he continued to tongue Claire’s pussy he could not help but wonder what his sister tasted like. He imagined it would be sweet and delicious. While he was busy romanticizing the taboo act of eating his younger sister’s pussy the girl he was actually performing the act on was rapidly approaching her first of what she hoped would be  many orgasms he would bring her too. His eagerness made it harder for her to control herself.

His tongue left her velvety fold and was idle for only a few seconds before his lips closed around her clit. His tongue went back to work immediately as two fingers quickly replaced it in her slick slit. The way she moaned, the way she moved and even the way she dug her nails deep into the sofa cushion were signals of how close she was but all of them were lost on him. He was too locked into his own incestuous fantasy to pick up on them.

“Oh god oh god oh god don’t stop.” She cried. His fingers moved deeper still while his tongue flickered rapidly against her tender clit. Her chest heaved with each panting breath as she let the sensation wash over her. “FUCK NATE I’M CUMMING!” She shrieked.

The sound of her voice cut through the haze and he immediately snapped out of his delusion. His fingers slid out and his tongue returned. He pushed it between her lips and began to lap up every last drop of her honey.  For several seconds after her intense climax her body trembled.  He rose to his feet and began to strip out his clothing while she tried to find the strength in her legs to move them.  He thought about just yanking them onto his shoulders and fucking her hard but the image of his sister still lingered in the corners of his mind.

“Get on all fours” He said rather sternly  “On the floor.”

It wasn’t the first time he had taken that tone with her. She knew that whenever he did she was in for some wonderfully rough sex. It was exactly what she had been craving. Claire gathered her strength and rolled off the sofa and positioned herself on her hands and knees. He reached over and grabbed one of the small orange throw pillows off the sofa and tossed it in front of her. She grinned as she reached for it. Her hips lifted higher as she laid her cheek against it. He knelt on the floor in between her splayed legs and inched forward until his painfully erect cock was rubbing against her.

The remainder of her juices that clung to her lips allowed him to enter her tight little pussy with ease. She let out a throaty moan as he slid balls deep in a single thrust. His fingertips dug into her hips as he held her in place. Everything hit him at once. The wave of anger his sister’s  response had inspired as well as the way he felt about the way those perverts wanted to use her culminated in a white hot rage that made all sense of gentleness fade into the background. He began to thrust almost viciously into his willing partner. She was the perfect surrogate to take it all out on because he knew she loved it rough. He rarely consented to give it to her that way though for fear of causing her injury or pain. None of that mattered now though. Someone had to pay and tonight it would be Claire.

He kept his jaw clenched as he grunted with every deep insertion. His movement was more animal than man as he thrust into her. She shrieked with pleasure as he fucked her so roughly, but it was not her voice echoing in his ears. It was Kayla’s. The images of her naked body flashed in his mind further fueling his depraved lusts. In that moment he hated everyone. He hated his sister for being so obstenant and refusing to listen when he just wanted to protect her. He hated Claire simply for not being Kayla, but most of all he hated himself. He hated himself for going there and agreeing to their arrangement and for allowing himself to experience all of the disturbing feelings he was harboring toward his sister.

He drew his right hand back. There were already faint hints of fingertip sized bruises appearing on her flesh. He was letting his dark emotions drive him. His hand came crashing down very hard on her firm round cheek. Claire jumped. She had not expected him to slap her ass like that. She started to buck into him, enjoying the rougher treatment he was giving her. Her moans were turning to pleasured screams as he drove his cock into her with all his might. Again and again he raised his hand and brought it down forcefully on her cheeks until they were both covered with warm red handprints.

He could feel her juices trickling out of her and running down his balls with each push. The emotions were giving way to the feel of her tight love muscles clinging to his cock. He could feel it building inside him. Everything around him seemed to fall away and all that he could focus on was burying his cock deeper. He grabbed a hold of her hips once more and pulled her back into his final stroke. Her juices washed over him as she walls shuddered around him. Her tightness was milking every last drop from him. He held her in place until he had emptied his entire load inside of her. When he released his grip on her she collapsed to the floor with a thud.

Claire laughed as she rolled over onto her back with her head on the pillow. Her chest was heaving and her skin kissed with a thin sheen of sweat. Nate sat on the floor a few feet away from her with his back against the sofa.

“I don’t know which one of those little sluts you were checking out on the site earlier but damn. I need to send her a thank you note.” She chuckled.

“What makes you think I was checking out the sluts?” He inquired as he watched her stumble to her feet.

She vanished into the bedroom, returning with a joint and red plastic lighter in her hand. “Because that’s what you are usually doing when you are on. You know I don’t care if you are fucking all of em. “ She inhaled deeply as she lit the joint and sat down next to him. “Just be careful.” She held the smoke in as long as she could before exhaling it slowly. “You don’t want them after that JollyRogers guy gets a hold of them.” She held the joint out, offering it to him.

Nate shook his head. “What the fuck does that mean?”

“I forgot. You don’t get all the gossip.” A serious look came over her. “That girl who had the avatar of Kagome, you know the one I’m talking about.”

“I remember her.”

“Well got her to come over to his place. Instead of it just being the two of them like he promised there were several other guys there that he invited over. He got her really drunk and they all took turns. “

“She hasn’t been on in a while has she?” He asked.

“According to Carrie, she killed herself. You know he tried to do the same thing to me. I told him I had stopped at the porn shop on the way to pick up some lube and had to run out to the car to get it and took off before the fuckers knew what was going on.”  She took another deep hit.

Nate was shocked. He just sat there with his mouth gaping open as the wheels began to turn. He knew that those perverts would do anything to get their hands on her.  His blood was boiling but he did his best to keep it to buried deep enough that she would not notice. “Did you tell the mods what they were up to?”

“Yeah but they figured I was just being a bitch because he slammed a few of my posts. I try to warn the girls but they don’t listen.” He just shook his head and reached for his clothing.  “Sure you don’t want any of this? I got it from Trev before he left for the lake.”

“Nah, I’m good.” He answered. “I need to get back. I got some things to take care of back at the house. I’ll give you a call.”

He was gone before she managed to get to her feet and walk to the door. Nate drove as fast as he could back to his house. He had to try one more time to get through to his sister before she did something she would regret.
