"Let go me!" cried a young wolf-girl, her undersized body wriggling in her older brother's grasp. Adva had been lured into her older brothers' room with the promise of a game for big pups, but so far it'd consisted of being undressed and touched & rubbed all over. Now Erez was holding her, stomach-down, on his own chest and belly, her arms pinned by one arm while the other held her tail up. Meanwhile, Erez's twin, Ofir, knelt over the young bitch, lining up his and Erez's cocks with Adva's tailhole and vulva, respectively.

Any further complaints Adva was going to make were preempted by a scream as she was penetrated, both holes stretching painfully around the penes being thrust into them. Even as the scream dissolved into pained sobbing, the teenage wolves began to thrust away into their new play-toy.

"Damn, she's tight," Erez commented, his hands now holding the young pup in place.

"Yeah. Think the elders probably should've waited a bit more before confirming her runtness, though," Ofir replied as he pulled Adva's tail up painfully tight. Her vulva and anus were both reddening with the abuse, tears running down her face. The boys' knots slammed into her nethers with soft whapping sounds; they didn't care if they damaged Adva permanently. She was a runt, and everyone knew runts were weak and valueless.

The sobbing stopped momentarily, Adva's muzzle opened wide on a soundless scream as Erez and Ofir's knots popped into her, one after the other. Her flesh tore, blood beginning to well from both of her holes, as her sobs began anew, even more agonized than before. The boys greeted their climaxes with a small bark of joy as their seed erupted into the unfortunate young puppy.

After several minutes' rest in which the boys' cocks twitched, filling Adva with their seed, they pulled out. This time, a true, agonized scream erupted from her throat as her vulva and anus tore further. Blood splattered on Erez's crotchfur and the towel laid beneath him as all three sat up. Ofir wasted no time, kneeling as he shoved his blood-splattered shaft into Adva's muzzle, forcing her to clean her own blood off of it. As Ofir choked off her screams, Erez shoved his muzzle between Adva's legs and began licking her bloody, bleeding anus and vulva clean.
