Valandor had been thrusting in and out of the punk bitch beneath him for a good ten minutes, one shot of cum after another entering her womb and and making her tits grow. She screamed for help and begged for him to stop, but it just wasn't going to happen. At first her screams had been turning him on more and more, but as time passed and her teats grew to monstrous proportions, it became hard for her to breath it seemed.

"Puh-lease! I'll d-huh-do anything! Juh-ust stop!" the four-legged female wolf said. She tried to squirm out from under him, her legs no longer touched the ground.

"Stop?" he growled down at her. "I don't think you want me too. I certainly know I don't. Watching your bounding boobs, oh! It is amazing!"

He moved so that his front paws were draped over her sides, feeling her last set of tits jiggle as he pumped his cock into her. He glanced down at the ground beneath her and saw that there was milk pooling around her. He moaned deeply, the thought of drinking from her making him cum automatically. Each of the quadrupeds gained another size suddenly, her breasts pushing her up farther from the ground. Valandor's body matched it though, his muscles expanding and body growing so he was still right at her tight entrance. Even his cock grew!

"Tha-t hurts!" she screamed out as he forced his cock into her. The wolf registered her screams, but paid them no real mind.

He forced himself farther in, making his knot split her sex. His head tipped back and he howled out in pleasure, drowning out her screams. He started to thrust faster, knot coming in and out with enough force to move her forward and backward on the ground. Her breasts were milked more, now flowing to his back paws and surrounding them.

Valandor could not stop himself as he withdrew completely from the femme he was raping. He swiped a paw at her ass, the force from his grown muscles making her roll over to her back. Her paws only came up about mid way to where her teats were expanded to. He watched with a smile as she flailed around, attempting to be turn back upright.

When she would get close though, her three sets of breasts would just make her roll back. With the added pressure to her chest, it seemed even harder for her to breath and he figured he could relieve some of that weight for her. Valandor's hulking body loomed over her, inspecting each individual teat before diving into one, his muzzle encircling the nipple.

The punk wolfess let out a reluctant moan as his tongue swiped over the nipple. She asked him to stop, but the wolf instead began to suck out the milk. He drank all of the milk that he couldg et from the one teat and looked up at her, some of the mammary cream dripping out around his muzzle. He slowly licked himself clean before his muscles expanded even more. He groaned, his eyes not leaving her face. It was the first time the female had see him grown and her eyes conveyed a deep sense of impalement as his muscles rippled outward, making his skin stretch and veins pop out.

"If only I could fuck you, drink your milk, and see that face," he said, in a low growl. He continued to grown, his cock slipping in between her massive teats. "That works," he commented, slowly getting a tempo built up.

His muzzle moved to another one of her breasts and began to suckle at the same speed he was thrusting. He moaned against her breast, and despite her cries of protest, her body did not seem to mind the abuse it was being given. His front paws slipped in between two sets of her teats, resting on what he believed to be her rib cage. Valandor, instead of moving his paws, just began to thrust faster into her mountains of breasts because he wanted to feel them move around his legs.

His body continued to expand outwards, skin becoming thinner and thinner over his muscles. He wasted no time moving on to the next teat, reveling in the growth that was occurring to his body. He moaned more at his bulking up body then the female wolfess's breasts. Valandor's veins began to pop farther out from under his skin. He could feel the heels on his back legs start to sting, but was to entranced in the amazing taste of this bitches milk to really pay attention.

The fourth milk filled teat did not make him grow nearly as much as the others, but it gave him more stamina. He was able to start grinding against her side faster, suck on her harder, and moan even louder. The brief reprieve from his rapid expansion seemed to allow him to adjust to his thinning and tightening skin.

He back off of the bitch and moved to her last to teats, sad that both of his paws would no longer be surrounded by her her soft flesh. As he moved, he could tell how big he was. Walking as a strange concept to this enlarged body. It was almost as if the muscles got in the way of each of his movements it seemed. He tried to turn his head and look at her, to see the fear and disgust in her eyes, but he couldn't; the shoulder muscles that had bulked up around his head made it difficult for him to move his head at all.

Valandor shuffled to the side, wanting to see his victims expression before continuing on. He wanted to be able to hold it in his mind as he continued to fuck her tits since he could no longer see around his muscles. The face he got from her was amazing! Her eyes were filled with disdain, her ears were back against her head, her muzzle was pulled up around her teeth, a deep growl coming out of them.

"Now what are you going to do to me?" she asked, spitting in his face.

"Pretty much the same thing I have. I want to be as big as possible, and you gigantic breasts seem to be accomplishing that for me pretty well."

He did not give her time to respond, instead tilting his body to one side and picking up his front leg, placing it over her neck. Then he leaned to the other side, moving his other paw to the other side of her body, brushing against her breasts as it moved all the way across the width of her chest.

As he got them situated, his cock slid in between the still filled with milk pair and the ones that he had already sucked out with ease, his pre-cum sticking a little bit to her fur. He thrust all the against her, his knot slipping into the cleavage as he began to suck. Her milk filled his mouth and he swallowed it eagerly, but as he started to grow again, even that action became difficult. He over looked it, telling himself that he would get used to it and all would be better.

He was so infatuated with his growth, he could tell the disaster that was unfolding all over his body. Without a second thought he moved to her final breast, awkwardly shuffling back so he could reach it with his muzzle. While his muscles grew, his skin did not, and at this point it was a thin covering over his body, the muscles clearly showing through, his fur no longer able to cover up the red colored muscles.

"Oh, you are so delicious," he said between suckles, savoring every last drop of her milk. She whined in response, not wanting to give him the satisfaction of her screaming anymore. He finished the last of her milk and licked his muzzle in happiness. "Damn good," he said, lumbering off of her.

He still didn't feel done, though. He felt as through he could be bigger. He stalked around to her sex again, trying to figure out how to do this with her on the bottom facing him. Then he remembered that his cock was massive and he could probably get her from just about any angle. He moved towards her, his bulging cock tip splitting her sex in no time. This time, though, it was rather painful for him. It burned and stung, but his body was already going at full tilt, pumping only a fraction of her cock in and out of her.

Then the rest of his body began to burn. He wanted to look and see what was happening, but he still couldn't move his head. The burning did not feel bad though, just a minor annoyances as he continued to bulk up. The expansion of muscle had him feeling to much euphoria to really notice the pain that was being caused by splitting skin and bursting veins.

As he came, his skin hit its limit. Rather than the milk from earlier, blood started to pool down around the female wolf and she started screaming. Her screaming only made her come more, which made more of Valandor's veins burst and skin rip. He only noticed when he started to feel lightheaded what was going on. His body had grown to massive to be contained!

The thought excited the wolf and he found that he couldn't help himself. Despite the impending doom, he continued to thrust into her, filling her over and over again with his cum. He pushed himself to the point the rest of his muscles all burst out of his skin at once, leaving a very morbid looking form. He reveled in it for a few seconds before the blood loss got to him, but he still didn't care. As he felt his life force leaving his body the only thought in his mind was how much he enjoyed the growth.

The female screamed louder than she had before as the pile of muscles and bones fell on top of her, molding against her breasts. Blood was pooled all around her. She squirmed about, the muscles and bones falling about on the ground around her.
