bluewildcat71:The brother/sister addition to the sci-fi comet/human knotting series that some have been asking for.Other parts of the story can be found here…Part one, Part two, Part three, Part four, Part five, Part six, Part seven, Part eight, Part nine He came awake moaning in his room. His cock hard and tenting his underwear, desperate with the need to breed. Brian took a deep breath as another wave of throbbing went through his cock. Someone was in heat.He whimpered as his hand rubbed over the thick growing bulge beneath the black cotton over his crotch. Fuck, he’d never hurt this bad with the urge to breed a cunt before.He walked into the hallway, his nose leading him to the room next to his. He pulled his cock out through the flap, fisting himself hard. Fuck… her heat scent was so strong. Strong enough for him to taste it in the air. His tongue felt like it was growing thicker the more he breathed that needy cunt smell in.God damn!He’d been waiting for her to come into her heat. Dreamed of what her little cunt would feel like spread around his knot.He groaned as he squirted her door with a splash of pre-cum.He went in her room quietly closing the door and locking it behind him. Her scent was so thick in the room that his hips started jerking, making him fuck the very air that surrounded her bed.Renee was tossing and moaning in her sleep. The comforter had long since been flipped off her body during the night leaving her t-shirt covered breasts and naked lower body exposed to the cool air. Like that was going to help cool the rising heat to breed in her wet cunt.He fought for control as he slowly spread her legs wider allowing him to kneel between her legs and get his cock closer to her weeping pussy. His cock was dripping a steady stream of pre-cum down onto her clit and he could see it twitching as it grew in size.Mmm, fuck yeah, his little sister was ready to be knotted and bred.He didn’t think anything about waking her. His every thought was about getting his cock into her tight little cunt and breeding her.He wedged the head of his cock against the small opening of her cunt and leaned over her, placing his hand over her mouth and then with a powerful jerk of his hips lodged half of his cock into his little sister.“Ahh… ahhh… godddd,” he groaned, the sucking sensation around his cock so intense as he tugged his hips back before he shoved in harder, forcing more of his cock into her.He looked down into her eyes as still not all of his cock was inside her. “It’s all going in,” he grunted, shoving in hard making her squeal behind his hand.“Every inch, sis… your little cunt…,” he jerked his hips hard and swift, getting a little deeper inside her heated cunt. “will suck my cock… and my knot,” He growled as he did a series of long deep strokes. “Until your belly… is full… of my seed.”Brian pounded the head of his cock against his little sister Rene’s cervix. His gut tightening as her tight little hole stretched and slurped around this thickening shaft.“Open up, sis,” he growled, punching his cock in faster. “Open up for your big brother.”He spread his knees farther apart, making his sister’s legs open wider, allowing him to dig his cock in deeper and deeper. He jerked her t-shirt up over her breasts and sucked her nipple into his mouth, biting down and then licking it, making her little cunt clench around his shaft with the flash of pain.“You want my baby,” he moaned against her breast, sucking hard before he look down into her eyes as he plunged his cock rapidly in and out of her wet hole.“You want your brother’s baby,” he moaned, pulling his hand from her mouth before kissing her hard, thrusting his tongue into her mouth.“Oh… oh god… sis,” he cried against her lips as the mouth of her womb started to slide over the head of his cock.He whimpered as her womb suckled his cock. The sensations went straight to his gut and drove him to slam his hips down into his sister’s body harder.He needed to get deeper. So much deeper.He threw her legs over his shoulders and bent her nearly in half as the ache in his gut grew and then urge to slam down with all his might took over.His sister screamed and he tried to muffle it with both hands, but as his knot formed inside the small passage of her tight little cunt, there was no way of stopping it.His knot throbbed within the gripping walls of his little sister Renee’s cunt as he started hunching on her. As the knot forced it’s way back and forth inside her, her screams slowly turned into moans as the knot pressed against nerves that were sending pleasure through out her body like she’d never felt before.When the orgasm hit his sister they both cried out. Her little cunt was grabbing his knot, squeezing around it and milking it. The mouth of her womb was wrapped around the head of his cock, sucking at him, sucking for the cum that would breed his little sister and it all worked to make his swollen balls let go and begin to fill his sister’s belly with his seed.He hunched and hunched, wanted to get more of his cock into her womb. To feel the mouth of it farther down his shaft. To suck his cock deeper into her womb.When his sister’s heat finally ebbed, five days had passed. His cock and her cunt were red and raw from the almost constantly breeding. The only time they weren’t was when they passed out from exhaustion. Even then, his cock was usually still buried inside his sister.He pumped so much seed into her womb that her belly was actually swollen by the time he was finished breeding her over those long heat filled days and nights.He’d much rather see her belly swollen with his baby, though. -- source link
