Chapter 3: A Poor Choice
Incest Sex Story: Chapter 3: A Poor Choice - Niki should have never taken that shortcut through the woods, at least not on the same day she had dared herself to go commando. What happened both shocked and aroused her, and once that path had been trod once, well, you will see just how many times Niki decides to walk that particular type of path. Note - not all codes are the same/available. This was originally published before my great purge, and is part of my cleanup/rewrite - being one of my older stories, it had quite a bit of work done

Max watched her with greedy eyes as she returned, looking over her young, freshly cleaned body with a smirk, his cock growing hard once more as she came closer. “Hurry up, my dirty little pet,” he commanded. Niki moved closer, eyeing Max on the couch and the dog on the floor. She felt a bit awkward, her naked body now fully on display, although with everything that had happened over the last few hours, it would be hard to claim innocence, or even much shock. She had debased herself completely.
Feeling him tug on her collar once he hooked it on, Niki tried to kiss Max back as he seemed to want, though she was fairly passive, accepting his kiss and his tongue, and letting his mouth overpower hers. She could feel his huge shaft throbbing as it pressed against her naked skin, and she knew that she was not done for the day yet. He would want more. Just thinking about his huge cock made her a bit nervous, and a bit aroused, as she kissed back, settling into his lap as he directed.
As they kissed, Cooper looked up at them, getting up from his place on the floor and coming closer to them. The way Niki was positioned on Max’s legs gave the Husky a great view, and she could feel him sniffing around her bottom.
It was a bit shocking when she felt the tongue graze her backside before beginning to work its way in, sliding across her damp lips, seeking out her pearls of juice as her inner lips slowly parted under the attack. She could feel the dog’s long tongue begin to drive her mad with forbidden desire. Just like in the park, the feel of a dog’s tongue on her most private area was driving her crazy with desire. Forbidden, naughty, oh so bad girl desire. The combination of her step-brother’s cock against her stomach and the Husky’s long tongue soon had her flushing with desire, rapidly returning to her previous, stimulation-obsessed state.
Max stopped kissing her and smiled. “Looks like he wants to breed his dirty little bitch again,” Max said with a chuckle as he reached down and gave her tummy a few smacks with his hard cock. “I will let you choose, do you want your big brother’s cock? Or can you not stop playing with your doggie boyfriend’s cock? The other one you are going to put in your mouth, so choose carefully.”
Niki felt her hips pressing back against the dog’s snout, almost as if she were an animal presenting herself. As she slid backward a bit, she grabbed Max’s cock with both of her hands, trying to cover it all, and failing. Stroking it, she pushed back again, feeling herself raising her hips even higher, as she then lowered her mouth to his cock, looking up at him. “I’m just. Bad,” she said, as she took the head of his cock in her mouth, its fullness filling her and stretching her lips around his shaft. Her hips pushed back, and her thighs spread as her kneeling form, straddling her step-brother on the couch, presented a naked, wet set of cunt lips to the tongue and snout of the increasingly aroused dog.
With a snarl, she heard the Husky begin to jump, and with a nip along her thigh, she spread just a bit more as she was suddenly buried under his furry body. She did not think the dog would be able to reach her where she was, but with her mouth on her step-brother’s cock, she was not sure how to move and not create a problem.
Niki realized she had consciously, or otherwise, chosen the dog’s cock over Max’s. He acted pissed, though she wasn’t sure why. He had brought the dog home, hadn’t he? And he was her brother for chrissakes. Well. Stepbrother. But still. Told to pick between two completely perverted options, she just picked what seemed easiest at the moment.
“You really are a bad, dirty dog cock loving whore. You are going to be punished after this for not choosing your big brother’s cock!” he said as he grabbed onto her hair and forced her to take down more of his cock, filling her mouth rather roughly. He moved his other hand down to push her legs off of his, which caused her legs to fall to the floor, while her mouth remained on his cock.
As soon as her legs were down on the floor, the Husky wasted no time in mounting her, his paws grabbing around her small waist as his hips moved rapidly in search of her entrance. His red, veiny cock was already poking out from licking her, and it continued to grow as he humped the air, getting closer and closer to entering her cunt. After a few tries, he finally found his mark, plowing his cock into her pussy with quite a bit of force, his claws digging into her skin as he pushed deep inside of her, moving onto his new mission of getting the knot inside.
Niki felt completely overwhelmed again. The dog’s hips were now jackhammering into her as if the beast had never had a fuck before. His quick, insistent need to cum was overpowering her small frame as she felt herself being slammed over and over. Her head bounced as she tried not to bite her step-brother while she was being rudely fucked.
As the Husky worked on getting his knot in, Max was keeping Niki’s mouth quite occupied. She could feel him holding onto her hair, keeping her head where he wanted, feeding her his cock over and over while Cooper pounded away. “That’s a good bitch, take it all the way down like the dirty slutty dog fucker you are.” Max pulled her up and let her catch her breath a couple of times before pushing her head all the way back down, filling her mouth, making her breathe through her nose. “You like being bred by Cooper, don’t you? You are one filthy bitch,” he said with a chuckle.
Mouth drooling, she tried to concentrate a bit on Max’s large cock, sliding up and down as best she could. Her hand cupped his large testicles as she bounced back and forth. Her small body slid nakedly against her step-brother’s legs, knees, and thighs as she worked to keep his hard cock in her mouth.
Over and over, she felt Max slide her head down, pushing deep into her mouth; she could not breathe once, but thankfully, he let her up. As she got used to it, and her mouth became a bit numb, she realized she was taking more and more of him inside of her, pressing against the back of her throat, bumping against it over and over.
Pop. She gasped as she felt it slide into her throat, so thick, so tight. She breathed carefully through her nose, her mouth gaping wide, drooling, as the thick shaft began to move within her. “What? I can’t help it. Can I?” she thought as she felt him pull her head back upwards, before sliding her down again. Bouncing back and forth at the same time, she quailed under the dual assault, her only saving grace, a realization that Cooper was not going to take his time, She could feel him swelling, and as her mouth filled with Max’s long shaft again, she felt Coop’s knot thicken, and her insides become flushed with the slightly viscous fluid shooting out of his canine prick.
Moaning, her cunt spasming under the renewed assault, she felt the knot stretch her painfully as the Husky lost interest and tried to move away. Realizing it would take some time, unless she wanted to pull away more firmly, Niki tried not to move too much, filled for the moment with the shame of wanting cock.
Pulling up and off Max’s cock after another minute of near gagging, she ran her hands up and down the saliva-covered shaft, enjoying the slickness of the movement, and marveling at how long and hard it was. She could feel her collar, the leash pulling down a bit on it, and, with a flush, she realized that she was everything bad she had been warned about. A cock sucking slut, on her knees, taking whatever her step-brother decided to do to her,
Max watched and chuckled as he saw the Husky finish inside of her, filling her up with cum once again that day. “You have had more dog cum inside of you just today than most breeding bitches have in a lifetime. You are one dirty bitch sis,” he said as he pulled her head up from sucking his cock, and pushed her down to lick at his balls while they waited for the dog to pull away.
Feeling the dog finally slide away, Niki reached back and ran her hand over her damp, sticky sex, sticking her fingers all through the wetness, feeling her swollen membranes. She felt so fucked. As soon as Max saw the dog pull away and Niki begin to touch herself, he reached down and grabbed onto Niki’s sides, pulling her up onto his lap in the same position as before, his pulsating, hard cock pushing up against her tummy.
He didn’t even give her a chance to brace herself before pulling her down onto his cock, pushing it nearly all the way in with a single thrust, the dog cum inside making it slide in so easily. “That’s it, take it all down, my dirty whore of a step-sister,” he said with a grunt as he pulled her back up to go for another thrust, hitting deep and hard against her cervix as he tried to get it all the way inside. “I said take it all!” Max said with an animalistic growl as he pulled her up once again and pulled down as hard as he could.
Moved around like an object, Niki’s mind began obsessing on the feelings she was getting. As Max’s large cock dove into her, she felt her body being lifted and dropped in one smooth motion. She felt her whole being become one of eager demand, seeking more and more sensation.
