Philomena lay on her bed and looked up at the ceiling. The sun shining in through the castle window played off the gilding of her cage, creating a crisscross pattern of light over most of her room — beautiful in a way, but so different from the darkness she craved right now.
She pulled her bangs across her face in an effort to shut out some of the sunlight and maybe be able to get a little sleep, but it was no use — they were too short to be an effective way to black out the sun. The short haircut pleased her owner, Princess Celestia, who claimed she liked it because it allowed her "to see more of Philomena's pretty little face," but Philomena was pretty sure Celestia made her keep it short out of spite, knowing that her pet preferred it long.
The princess had had Philomena performing services for the diplomats that had been visiting that day from Yakyakistan — showing them the best hospitality that Equestria had to offer. Although she did always relish an opportunity to please her princess, she herself hadn't gotten any relief of her own — a situation she always found frustrating.
Lacking anything better to do, she allowed her right hand to wander down her flat stomach and parted the feathery plumage. Her fingers found the soft skin of her pussy lips as she parted her legs to give herself better access.
She looked around. Usually she'd have to ask permission to do this. In fact, usually she'd be ordered to do this. It felt wrong to take matters into her own hand, so to speak. But this evening it just felt necessary.
Philomena rubbed the lips of her pussy up and down. She was completely dry inside right now, and any deeper stimulation would be uncomfortable until she'd moistened up a little. She could use a little saliva, of course, but she preferred to use the other type of wetness, and as expected it wasn't long before she felt a familiar warmth and moisture down below and smelled her scent in the air.
Her fingers delved between her lips, spreading her juices around her pussy as lubrication. She rubbed the moisture up to her clit, her fingertips brushing over it. As tempting as it was to start rubbing her most sensitive part straight away, she resisted the urge, knowing it would feel even better later.
She ran her fingertips over her inner lips, slowing down when they got to the part closest to her hole. After three cycles around the edge, she felt some more drops of juice dribbling down the bridge of skin between her pussy and anus. She rubbed the liquid into her skin, before dipping two fingers into the hole it had come from.
Her left hand went to her chest, tugging at the bindings that she'd been made to wear that day, the good folk from Yakyakistan apparently having a taste for that sort of thing. Her small breasts sprang free, and she cupped one, kneading it and rubbing the nipple between her thumb and forefinger.
Philomena let out a breath she hadn't realized she'd been holding as her fingers curled up inside her. She began to move them slowly in and out of herself, relishing the feeling as they slid smoothly over each bump of her pussy walls.
As the minutes passed, she picked up the pace, her fingers moving faster inside her, and the mashing of her breast becoming more fervent. When she desired more girth she let a third finger slide inside her warm pussy. She even put her little finger to good use, teasing her anal opening with it, but without enough pressure for it to slip inside.
Her breaths and heartbeat became more rapid too, partly due to her exertion, but mostly a sign of her growing arousal. She moaned, closing her eyes, and tilting her head back on her pillow. Her hand slid up from her chest to her neck, pressing down on her windpipe. She tried to imagine it was Princess Celestia choking her, but it didn't feel quite the same as when her owner did it.
Giving up on that idea, she moved her hand back down to the other breast, pinching the nipple hard and biting her lip while she dug her nail into her flesh, the pain pushing her closer to the edge.
She pressed the ball of her thumb hard against her clit while she fucked herself with her fingers, digging the three digits deep inside her pussy. Her juices now flowed freely, but didn't extinguish the burning feeling in her loins. An intense heat was building up inside her, feeling just out of reach, no matter how deep she thrust her fingers.
Her thighs began to quiver as she felt her climax approaching. Just a little more. She pressed her fingernails into her nipple again, harder this time, the sharp tips breaking through to the flesh and drawing blood.
Philomena cried out in pain and ecstasy, curling up her claw-like toes. The heat in her belly spread rapidly through her body like a wave of hot pleasure. The skin of her stomach, legs, chest, breasts, neck, arms, and face erupted in bright yellow flames, which licked her wounds, healing her and rejuvenating her body.
Philomena lay panting while the flames on her skin flickered and died down. Soon, the only evidence of her combustion was the dusty black ashes of her burnt feathers surrounding her on the sheets. She withdrew her sticky fingers from inside of her, and licked them clean, before sighing in satisfaction.
She bent her legs to stroke their smooth skin. She liked them featherless like this. It was a shame the feathers would grow back by the morning.
The sun had crept below the horizon, and no longer shone in her eyes. Philomena rolled over and tried to get some sleep.
Author's Note
Literally the hottest orgasm I've ever written. 
Who would have thought pet play, choking, blood, and spontaneous self-immolation could all be squeezed into a thousand words?!
