“Meet Jenny Lane. well that’s who she thinks she is. Well she is a little confused, we only brought her round to her new life an hour ago. When we decide what her new name is to be and she comes to accept what she is now, she’ll grow in to it. Then in no time at all, even to herself, that's who and what she’ll be.” The man sat on the lawn chair drinking his long cool drink contemplating. “Jenny used to be a plump little thing of five foot two with rolls of fat around her middle and a big arse. She used to moan all the time about how she wanted to get in shape but she had this metabolic problem.”

He got up, the cold glass still is his hand and wandered up to her.

“Her metabolic problem was that she ate to much of the wrong things and that she didn’t exercise anything except her tongue. She won't have that metabolic problem anymore. She’ll only eat what she’s given and sweets will be a treat for good behaviour. Though she’ll still get the opportunity to exercise her tongue! “

He held icy his glass to a fat nipple and she started to pull back but of course she wasn’t going anywhere fast with the dildo shaft on the buggy pole hard up her butt and its brake on.

“Well, she did finally take the plunge and join our ladies only gym. It was so much less embarrassing when the only men about where the dishy instructors who were so sympathetic to her problems.”

The girl shifted uneasily on her tiny hooves, unsteady and unused to being kept on tip toe, trying to make the big shaft that filled her achingly full disappear.

“Now of course she’s perfectly in shape. Her arse may still be a little large, a regular bubble butt, now though its all muscle. And without any exercise! - Yet!”

His hand cupped a latex covered buttock and squeezed the firm muscle hard. The girl moaned in protest and tried to shift away again but she was still going no where.

“Anyway if it was too small a butt it would be out of balance with those nice big tits she’s got now.” He whispered into the shaking girls ear. “They could get larger still my little pony if I decide to turn you into a milk mare.”

There was a choking moan from around the bit and he could see her flush and beads of perspiration stand out on her velvety skin.

His hand caressed her hard flat stomach under the magnificent overhang of the big breasts and he could feel goose bumps rising on her skin. Then he allowed it to drop down over the waist band of her skin tight latex trousers, on to her lower belly and protuberant mount, until he found the opening at her crotch from which her fat pussy was extruded. He flicked the bell that hung from a clit the size of a cherry and she tried to dip away from him. The moan this time held overtones of reluctant excitement.

“It didn’t take a lot of research to find out that she was a prime candidate for recruitment and a bio make over. Estranged from her family. Fat and lonely. Vain and selfish. A tongue that could be cruel and vicious. The perfect candidate for a place like this where her tongue can get all the exercise it needs without the need, or the ability to speak. Who ever heard of a pony needing to do anything other than whinny after all!”

The girl was moaning now and it wasn’t because he was resting the cold glass against her six pack.

“My, my. Don’t the tears make her big beautiful eyes fill so. It must be a shock. Do you think she’ll like her new face when she gets to see it eventually?”

He turned to the maid in her skimpy costume. She stood, still holding a small silver tray, her beautiful full lipped face expressionless. Her towering heels were sinking slightly into the firm turf but she was compensating by coming more onto her toes and it presented her lush buttocks beautifully, even as it made her thrust out her big tits. Tits that were made to seem larger still because they were offered up above a heavily corseted waist on a nest of white latex lace that contrasted so well with the black of her uniform. The heavy nipple rings glinted charmingly in the sunlight and he found the sight good.

“Oh, I forgot! Maids don‘t need to be able to speak either do they? Just obey. Well perhaps you would like to use that tongue of yours to give me a little oral relief before I start the training of our new foal.”

In an instant the tray was dropped and the girl fell to her knees in a flurry of stocking tops and bare buttocks, her own clit bell tinkling with a ringing that managed to sound both eager and willing. Nimble fingers worked at his breeches and soon his rigid cock was engulfed in a hot wetness and he felt himself being taken deep into the maids throat as the new pony looked on in horror, still shifting to find ease from the invading shaft that filled her aching belly.

How good it is to be alive at such a time and such a place, he thought, where a man can enjoy all the benefits of the bioengineering and the Demon Seed in particular.
