"Shh shh, it's alright, don't worry"

She pulled on the restraints around her wrists, half playful, half testing their strength. She could only moan around the large ball gag between her teeth and when she tried to speak or scream only muffled squeeks made it past her lips. It was wonderful. He must have mistaken her excitement for panic, which was only partially the case, because he stroked her cheek with a fingertip and smiled at her. She looked back at him with feverish eyes, urging him to continue, trying to send the words straight to his brain to make up for her inability to speak.

"It's alright, babygirl, just trust me"

She saw the flecks of blood on his fingers when he picked up the scalpel again and pushed her chest up. Half in struggle, half to try to meet the blade with her tits so he could cut her again. He looked at the red lines criscrossing her full tits, pausing and taking in the view. She wasn't bleeding too much yet, a couple of drops running down her skin, tickling her sides, staining the sheets, but it all felt rather held back and shallow. He could see her dilated pupils, her nostrils flaring with every deep breath, the blush on her cheeks and he could smell her cunt, knowing how wet she was without even looking at it. Oh he knew how excited she was, and he knew they were only getting started.

A sharp intake of breath when he pinched her nipple. A soft moan when he pulled it, lifting her tit. Quiet anticipation when he pushed the razor point of the scalpel against the tender skin at the bottom of her tit. A muffled scream when he pulled the edge over her skin, slicing with the length of the short blade. Her skin parting, filling with red, a few beads forming and breaking free from the cut to crawl down to her abdomen. Switching his hand to the other tit, he repeated the process, now knowing how much resistance to expect, cutting deeper, making her bleed more freely. He saw her eyes half closed, unfocused, her head thrown back in bliss, and he knew she was gone. He could do whatever he wanted. She was as much a painslut as he wanted her to be, as he cultivated her to be for the past year.

He shifted on the bed and moved his hand down her hot skin, pulling red finger marks down from her tits to her soaked slit. Her legs were held wide by the cuffs and straps, as immobile and secure as her arms, she was completely spread and helpless. His fingers slid in without resistance, and as his fingertips pushed onto the soft spot inside her, his thumb found her clit. Gently stroking, making beckoning motions with the two digits on her g-spot, with his thumb pressing, rubbing and circling her clit, she tensed up and arched her back. The combination of her tits on fire, her sweat stinging in the cuts, and the slow teasing fingerfuck made her lose her mind. Trashing her head sideways, inhuman moans and guttural screams muffled by the gag, she bucked on his fingers until she came. And again. And again. He kept going for as long as she had energy, rubbing and fingerfucking and teasing and twisting his fingers inside her the way he knew she liked. It wasn't until the orgasms calmed down and turned into a gentle stream rather than meter tall waves that he held still, his fingers still inside her.

"Was that good, dumb little cow? Then let's get really started"

He pushed up with his fingers inside her as she looked at him with confusion in her eyes, making her push her hips up and tighten her abs. The first slice down her abdomen was light, shallow, barely breaking skin. She closed her eyes in enjoyment. A sharp grunt betrayed her surprise when he pulled the blade over the same cut, tracing it, going slightly deeper, drawing blood this time. He didn't give her a chance to recover, and put the tip of the scalpel at the top of the cut and pulled it down again. She tried to pull away, but the firm restraints and the fingers in her cunt held her in place, putting tension on her skin. He wiped away some of the blood that now flowed freely from the slice, and smiled at the hint of yellow in the cut. Another draw of the blade, and her flesh parted like a blossoming flower, showing the thin layer of fat that kept her soft. Ignoring her frantic moans, he stabbed the scalpel in until he felt the texture change, and cut down in short, deep strokes, separating the fat and exposing the muscle below.

She was gone. Mentally checked out. Aware of the pain deep in her belly, feeling the blood pool under her back, the red hot fire of the scalpel penetrating her deeper, she knew that things were very wrong. Riding the aftershocks of her endless orgasms, and knowing to her core that pain equals pleasure, she also knew that things were very right. Whatever he wanted. It was all good, it was right, it was perfect. She did her best to lay still, afraid that her trembling and jerks would ruin his enjoyment.

He pulled his fingers out of her dripping cunt, wiped them on the bedsheets and used them to pull the wound open so he could cut into it again, deeper, slicing into muscle now. He knew that anything so far could heal with some care and time. Sure, it might leave a scar, but superglue or stitches would fix most of it up again. This was different. As he cut into her abs he knew he was making a hole into a muscle, he was doing real damage. Beautiful permanent damage. He went slow, a millimetre deeper at a time, using the previous cut to guide the blade and part her body open more with minimal pressure. He wanted to be careful, to open her up without puncturing anything internal. He didn't want to make a mess, after all. He almost laughed out loud at that thought, with blood up to his elbows, flowing from her flat sexy belly like a stream and making a puddle around her ass where it rested on the mattress. She thought she heard him laugh through her haze and smiled around her ball gag.

It took a good couple of minutes and dozens of cuts to make his way through the muscle, only to find more muscle underneath. He put down the scalpel between her tits and got up to stretch his legs, massage some feeling back into his hands and close his eyes for a minute. Once rested he switched out the blade of the scalpel for a fresh one and got to work again, one shallow cut at a time. She didn't even notice him getting up, her eyes rolled back into her head, lost in a world of pain, her continuous moan equal parts pleasure and terror.

Separating layer after layer of muscle, more and more careful the deeper he went, he felt the last muscle give way and the last membrane open for him. Pushing his finger deep into the cut, he could feel he'd finally reached her abdominal cavity without damaging her internal organs. Pleased and rock hard, he threw the scalpel to the side and went for his prize.

She felt the bed shift under his weight and snapped back to reality. Her eyes opened and focused, just in time to see him climb on top of her. His hand closed around her neck as it had done so many times before, strong and unforgiving, letting him decide whether she could breathe or not. It was different though. She was a fair bit shorter than him, but his chest was practically above her face this time where normally she'd reach his shoulders. She tried to swallow, she tried to struggle, she tried to ask what was going on, but the combination of the gag, the blood loss and the fingers squeezing her throat shut gave her a lovely pink haze, a warm blanket over her mind that made the questions and resistance melt away. And then the pain in her belly grew. She could feel the tip of his cock stretch the wound open, slide past all the layers that kept her insides inside her, and invade her body. The cut stretched, ripped, opened wider and her skin gripped the cock, trying to hold on to it, to keep it out, to pull it in. His body met hers when he went deeper, and she could feel her guts rearrange themselves around him. Even more slippery than her cunt, her intestines were moving and sliding and rubbing against his cock. He picked up the pace, actively thrusting into her body, squirts of blood filling her belly, and it felt like getting punched in the stomach over and over again. She felt sick, nauseous, like indigestion or cramps, but the pounding into her body felt so familiar that she tried to thrust back. He grunted, slamming into her, and filled her abdominal cavity with his cum. Pump after pump flooded her organs, getting between the folds of her guts and flowing deeper into her. He collapsed on top of her, spent and exhausted, releasing her throat just enough for one shallow rasping breath to keep her alive and functional for the next fuck. Her oxygen and blood starved brain just gave her one thought and she giggled under him while he pulled his cock out with a wet sucking sound. He used to call her a three hole whore. She was a four hole whore now, though, with possibly more to come. It was wonderful.
