His Mistress was very interested in keeping him healthy. He was fed a healthy gruel that contained all the daily nutrients he needed, had just the right amount of carbs, no sugars, was all-natural, and though it tasted pretty much like shit, it was good for him. This was supplemented with plenty of water (not just Her piss, but regular water as well), and daily vitamins.
Often time Mistress would leave the gurls in charge of his feeding times. Normally, Mistress had just fed him out of a dog bowl on the floor, but the gurls loved to actually feed him as if he were a child, incapable of such a simple task.
Oh, sure they would use the bowl, and place it on the floor, but rather than let him dive in and eat in the normal way any dog would, they would dip their toes in the disgusting gruel and then push those toes into his mouth to lick and slurp the food. How they would giggle and tease him during the feeding. He would blush crimson each time they shoved a gruel covered toe into his mouth, while the other smacked his ass with her hand, or if feeling particularly horny, would just fuck him as he ate.
Sometimes they would even smear the food all over their cocks, and then make him suck and slurp the food off their cocks, telling him that if he did an extra good job of eating all his food, he would then get a creamy dessert. The joke was on them though, he had come to love their creamy desserts.
There was also his exercise regime to keep him in shape. First there was the daily walks. Sometimes Mistress would take him, sometimes one of the gurls would take him. Out into the backyard, if they wanted to keep him naked, or sometimes they would dress him and take him to a park. Mistress would often times walk at a leisurely pace, but the gurls would set a grueling pace, being much younger and he would be exhausted by the time they got home and put him in the shower to wash him, and then get him started on his chores.
For rainy or very cold days, there was the treadmill and stationary bike. These two things he came to both love and hate all at the same time. Mistress had very strict guidelines for the use of either in regards to Her pet.
pet must be supervised at all times while using one of the devices.
when using the devices, the supervising Miss would make use of a riding crop or tawse to ensure that pet maintained the appropriate pace during the workout. striking ass, back or thighs in order to encourage pet to get the required cardio-workout.
when on the stationary bike, pet would be mounted on a butt plug or dildo and would be required to "ride" said item while riding the bike in order to maintain a proper stretched out hole for more pleasurable times later. (The Gurls particularly loved this, since they were now the primary users of his hole).
He was required initially to spend 30 minutes per day either walking or biking, or sometimes a mix of both. Mistress and the gurls made sure that he kept to that schedule. Now keep in mind, that was 30 minutes at his top pace. He was expected to start slow, and gradually increase the pace, so that he often times spent between 45 minutes and an hour on the contraptions.
While exercising, pet was also to be properly hydrated, and Mistress was somewhat lax on this, it could be piss or water, whichever was most convenient at the time of his workout.
The gurls would often times forgo using him in the morning, and fill a large 64 ounce water bottle in the mornings with their piss, and would add to it, if it didn't get full first time prior to his workout, and would use that to keep him hydrated during his workout - supplemented with regular water bottles as well, so that usually by the time he was finished with his workout, his own bladder was so full, he was practically bursting. The gurls would then make him hold it while they cooled off from their exertions swinging crop or whip before taking him outside to relieve himself.
Yes Mistress was quite determined to first off get her boy into good physical condition so he could properly serve Her. After a year under Her care, he had lost close to 50 pounds, and was in, what he felt to be, the best health of his life. He had more energy and more stamina which was very good on those nights when Mistress would gather the girls, and perhaps a few of Her close friends and they would have fun with him in a variety of often painful, yet erotic ways that would leave him, by the time they were fully satisfied, exhausted.
So healthy, if disgusting, food and exercise were well in hand for Her pet, and Mistress was quite pleased with his progress. She would set goals, nothing too out of the realm of possibility. He didn't have to lose ten or even five pounds per week, but he needed to at least be losing one to two pounds per week, or else face punishment and an increase in his workout regime. Only rarely did he miss the goal, and there were usually extenuating circumstances. Oh, he was still punished, but perhaps not as bad as if he had just slacked off.
Of course there was also a lot of sex. The gurls had full permission to use him pretty much any time they wished, and being young and extremely horny little vixens, they took full advantage of that, often times surprising him during his chores for a "quickie."
He could be scrubbing the kitchen floor on hands and knees, and to his great surprise would suddenly feel a hand grasp the back of his neck and shove him down, and then a cock press deep into his hole. He never had a choice, and he accepted their attentions. Sometimes they were quick and brutal, just wanting some fast relief. Other times they took their time and truly worked to humiliated him during the surprise fuck.
Mistress, when asking him about his day, of course expected to hear all about these little occurrences, and he would recount them to Her while rubbing Her feet, and depending on how well he told the tale, he would soon be buried between Her thighs while She ground against his tongue to blissful, relaxing orgasm.
So even though his cock remained firmly locked up, he was used quite often sexually.
Speaking of his chastity, that was a large part of his health regime as well. Mistress was quite keen on cleanliness, and She had carefully taught the gurls how to properly clean and care for a properly chastised cock.
This included his "milkings." He was never released for these, unless it was an orgasmic reward as recounted in the previous chapter. Now, these were not meant to be pleasurable, they were for health reasons. Though he suspected his humiliation was a big part of it as well.
