Billy had arrived right on time, standing in the shadows, just outside of the doorway. His trousers were already open and his erection was jutting upwards from his slender groin. His eyes were fixed on Lara but they never strayed to her face, they were glued to her on display body, unabashed, lust-tunnel-vision, his eyes burning with his desire for her.
Lara suddenly noticed and with a new and startling realization, that Billy's erection was something like twice the size of Derrick's. The realization shocked her and she found herself helplessly staring at it. Watching it pulsing visibly with need. With desire, for her, for her body.
His grief and thoughts of Becky, how she had committed suicide rather than come over to him, seemed to have faded from a few hours ago when they had sat together and Lara had tried to comfort him, wipe away his tears, console his raw grief. He had thought it had been about him at first, Lara had managed to convince him that it was Becky's own sense of shame, that she had rather died than gone on living with what had been done to her. Billy had tried to save her but she had been un-savable. That he had tried his best but she hadn't wanted to go on living after those days in that house, and probably whatever had been done to her beforehand as well.
He had done everything he could, she just didn't want to be saved. Not like Lara. She needed to be saved. She had tried to broach the subject but recognized it was probably was a bad time to do it, but she was desperate. And now she was under Derrick's control yet again, another day of taking his cock and his cum inside her. Being his whore, being the vessel for his increasingly violent lusts.
She was so ashamed of it all. That Derrick, Billy's little bullying, overweight, bratty friend, was getting to experience her pussy and mouth, to feel them around his cock. He was getting to feel what her tight little pussy felt like sliding up and down on his shaft. In the past Lara had been very careful to choose who got to see her naked, who got to put their cocks in her and that was how it always should have been. But now, Billy saw her naked day after day and Derrick, this sadistic teen, had total possession of her body. It wasn't long before that she had been in charge of him, in charge of the both of them and yet now it was all for Derrick. Every inch of her she had given him. She had been given no choice. Right now, he was able to look at her little puckered asshole as she rode him, his cock deep inside her, his hands on her all over her, wherever he wanted to put them. And there was nothing she could do to stop it. She needed Billy to step up. Desperately. There were no two-ways about it. It was the only possibility.
She was an attractive young woman that boys and men had always wanted to fuck ever since her earliest teenage years, she had long recognized that fact. And now with no society or laws or consequences to control them, without the security of this little suburban fortress, all her holes would be up for grabs. But as of right now, even within the walls of their fortress Lara was a slave to Derrick. Her holes belonged to him and she hated that fact.
And there was Billy. Watching. Like always. Spying on them, watching Derrick rape her and getting off on it. Lara was so naked and on display, her completely nude body right there for him to stare at and fantasize over, even as Derrick used her, making her fuck her hips up and down on his thrusting hard on, Billy used her too, with his eyes.
She wanted to hide from Billy, wanted to hide her bouncing, shuddering tits, but Derrick wouldn't let her if she tried to. And the position he had her in she needed her arms to keep her up and balanced anyway.
Derrick leaned up, giving up on his thrusting into her from underneath, instead opting to make her do all the work while he grabbed her wrists and pulled her arms back behind her, making her quivering tits jut forward more prominently, displayed for Billy.
Lara looked over as she rode Derrick. And couldn't hold back a hissed curse, as Billy stared, wide eyed and intensely horny.
"Oh fuck!" She moaned.
Derrick, of course, assumed her outburst was down to his performance, but it was Billy's cock. He was so hard, big, solid and throbbing obscenely, obviously. As he watched Lara bouncing on Derrick's cock, he was hard after seeing her naked. It made Lara question his motives.
Didn't he want to rescue her instead of just looking at her tits bouncing and pussy being filled and defiled day after day? Didn't he want the reward she had suggested? Could he even rescue her if he wanted too? Probably not... She thought with a sinking feeling. Compared to the way Derrick had stood up in the aftermath of the world ending, the way he had taken charge and taken what he wanted, Billy was weak, unable to match Derrick's aggression. It was hopeless wasn't it?
"I'm probably the first naked girl he's ever seen..." Lara thought to herself with rapidly increasing despair. "...He's not man enough to rescue my pussy, just watch it and jerk off to it."
Then she felt really alone, for the first time. Alone and helpless. She knew Billy wouldn't take on Derrick, she couldn't see where that thought of hers, that desire had even come from. In that moment she just wanted to be left alone with the gargantuan weight of her own despair. Fuck it, Derrick had her and was going to continue to have her, but Billy standing there passively watching and getting off on his big sister's plight was suddenly too much for her.
"Please Derrick, close the door..." She moaned silently, to herself, feeling tears welling again.
But then she remembered how Billy had been earlier this very night, going out with those Molotov cocktails. Killing men, so determined and sure of himself in order to rescue Becky. Why couldn't he have that determination for protecting his big sister? If he could find that determination in him for his sister. Then maybe... Maybe.
Billy.
Billy stood and watched his sister taking Derrick's cock. It was like an addiction now. He was obsessed with watching Lara being used. He had wanted the same for himself and Becky had been his best chance. He had envisioned it. Derrick fucking his sister in his parent's bed while in his own bed he and Becky would be fucking just as often, just as much and just as noisily. But Becky was gone. Killed herself. He chose to believe what Lara had said. That what those men had been doing to her was too much for her to live with. Better to be dead than live with that. It made Billy angry. Angrier than he had ever felt before. He felt betrayed by Becky's choice. He felt hatred for the men who got to her first, who took her away from him.
They could have been happy here, fucking and surviving in the house together. He would have happily burned them all to death and brought the Pritchard's house down to the ground. But at the same time, he couldn't have risked being identified and followed back to his own house. So, he had run, down the street, down an alley, around the back of the houses on the next block and then a wide circle back to the rear of his own house, sneaking through other's backyards, using hedges and fences to keep something between him and the Pritchard's house at all times, until he was back in his own backyard and Lara was letting him into their fortress again.
Apparently, Derrick had taken a similar route to get back to the fortress when he had spotted the disturbance in the street outside their house. It was odd really. Everyone on the street essentially kept to themselves and remained so quiet that no one really knew which, if any, of the houses around them were occupied. According to Derrick, it was always a huge risk to break into a property. You never knew who you might come across and if they would be armed. These days more than ever, people tended to shoot first and not even bother to ask questions.
So, most of the houses on the street were deathly quiet and dark and unmolested. The Pritchard house had always been the exception, there was always noise and obvious danger from there. Which was why no one else went near it either. It was the visible danger, while the other houses were the invisible danger, the risk of danger. Both of which, essentially, amounted to the same thing. Stay away if you value your life. It often had Billy wondering where Derrick actually went to scavenge for supplies, if not for the houses on their block, where else was there?
Billy watched his sister taking Derrick's cock.
There was a detachment he felt while he watched, in order to deal with Lara being raped so often, forced to comply with Derrick's desires. Billy's friend had been talking dirty for years about what he would do to Lara if he ever got the chance, Billy had always been half turned on and half disturbed and disgusted by his friend's filthy descriptions. And now he had made it come true. And that half and half reaction was just the same in Billy, but this time he had detached the disgust and sympathy and instead enjoyed the dirty sexiness of it.
It was always easiest when he was turned on, but when he wasn't horny he was wracked with guilt and sympathy for his gorgeous big sister. But when he was horny he was all for it, to hell with her suffering he just wanted to see her naked and fucking and making Derrick cum. If she did it for Derrick, he could almost imagine her doing it for him too.
His sister's body was amazing and it always had been, for as long as he had liked girls he had liked Lara best, first and foremost. All those summers with her in her bikinis by the pool. The tiny summer dresses that floated, got caught by the wind, flipped up wherever they weren't clinging to her curves. Those moments had fuelled Billy's and Derrick's horny desires for years and now there was a whole new reality. Billy was not only getting to see her naked from plenty of angles, but he was also getting to see her in action, getting fucked, made to suck cock. He saw her sex face, the lovely pink flushes that danced across her taut, tanned flesh.
Of course, Derrick had it better than anyone. He was actually getting to fuck her. Whenever and however he wanted. While the best Billy could hope for was seeing her naked tits bouncing, those sweet strawberry nipples, hard and poking out as they bounced and quivered in time with Derrick's thrusts, the views he had of Derrick pawing at his sister's great ass. Her shaved pussy, the lips spread around Derrick's erection, he had even caught glimpses of her clit and her ass hole too in the right light. That was a thing that he had always wanted to see more than anything else. His sister hot little ass hole. But he had never seen Derrick fuck it. That was something he wanted to see.
He would have fucked Becky's sweet ass in a second. It was one of her best features and Billy had often jerked off at the thought of it, squeezing his fist harder and harder around his cock, pretending it was Becky's ass hole squeezing him. Sometimes pretending it was his sister's ass hole around his cock. Tight and hot and gripping. It never failed to get his spunk flying. There was another pang of regret and frustration. It was something he'd never get to do with Becky now. She was gone for good. But there was Lara. His sister had suggested stuff. Implied stuff. And, more than ever, he was coming around to the idea. He had killed for Becky, so he could fuck her and keep her safe.
That was no longer possible. She hadn't wanted his help. But he had done it all the same. He had killed. But Lara, she wanted his help too. He didn't owe Derrick anything. He was a bully. He took advantage of Billy, ridiculed him constantly. He hurt Lara every day, and Billy was jealous and getting more and more angry by the day as a result.
Maybe that was it... Maybe Becky had been a test. A test to see if he had it in him. And now Billy knew. He definitely had it in him. He had proved that to himself. And to Lara. He hadn't failed that test. Becky had failed it, choosing death over Billy, but Billy hadn't failed. He could do it. He could protect Lara. And he could stand up to Derrick.
And what Lara chose to do right at the moment was the icing on the cake. And for Derrick, the last nail in his coffin.
She was astride Derrick's flabby, pasty body just as the sun started to paint the world in color. Her knees up, feet on the mattress to lift her up and down, her arms locked holding her up above him, palms out on the mattress like a crab walking posture, bouncing her ass over his groin with the same vigor and pace that he always demanded of her. Her blonde hair was pooling around her shoulders and chest and her head was forward, chin to her chest, her hair cascading over her face, almost hiding her features but not the distinct flush to her cheeks.
Derrick was gripping her ass cheeks in both hands and trying to time his upward thrusts with her downward ones. He looked like he was close to climax, his was flushed and sweaty and getting more and more aggressive and vocal.
Lara tossed her hair, threw her head back so her hair was in Derrick's face but just as he let go of one ass cheek to shove her hair or her head out of his face, she lifted her head again and then turned to Billy, caught his eyes with hers and held them.
