Derrick shivered as Hebe's hands slid over his skin. It felt good, yet also odd, as the water and her palms washed away more grit. He had to keep reminding himself that the fine sand was actually time, or some strange manifestation of it. His sexual equipment appeared to grow even larger, but it was his body getting smaller around it, as well as the loss of the red thatch that had been surrounding it.
Hebe's attentions shifted to his face, and her fingers slipped into his mouth and traced his ears. One more quick pass over his body and limbs, and she stepped back. "It is terribly tempting to keep going, to regress you to a babe in arms again. But you have offered a level of trust that I would rather not betray. See what is done, Derrick. Any more and that marvelous package will not function for a while."
Climbing out of the pool, Derrick found his way to the mirrors. He felt light and full of energy, and saw that Hebe had changed his build. Instead of the musclebound farm boy, he looked like a trim athlete, a swimmer, wrestler, or bicycle racer. His sexual equipment would create a rather attention-getting bulge in any form of pants, but wasn't so big that it would interfere with activities. Other than the obvious maturity of his crotch, he looked like a really well-developed prepubescent boy, thanks to the loss of all his body hair. This extended to his face, which showed no sign of facial hair other than copper-red lashes and eyebrows. However, the face itself made Derrick frown.
"I'm sorta ugly!" While maybe an overstatement, the coarse-featured boy reflected back at him was certainly not handsome in any way. An upturned pug nose with a smattering of freckles sat under large, pale blue eyes that looked a bit unfocused, and his ears stuck out like handles. There wasn't much of a chin under a wide mouth that was pushed out by oversized teeth, and the thick tangle of copper-red hair did not really hide the fact his forehead was low. The overall effect was cute in a way, though he looked like he might not be very smart. It was hard not to smile, and when he did the effect was disarming. The bright white teeth and puppy eyes created an impression of friendliness and happiness.
Hebe moved to stand behind him, draping her arms over his shoulders in a loose hug. "Nice-looking young men are a dime a dozen, and their attractiveness tends to fade over time. You have an interesting face that will remain appealing over what is likely to be a very long life. You will not age the same away as other humans. In ten years you might look 16, and when you are 40 most would think you are fresh out of college. At 60 you will be able to pass for half your age, and at 100 you might look like you are a youthful 50."
A hundred years old? I could live that long?" Derrick stared in wonder at his new self.
"Far beyond, actually." Hebe grinned and tousled his hair. "Barring accident, you should easily make it to 150. Unless you choose to return here one day and let me tweak you again."
"But.. what about my family? Will my parents let me stay like this?" Derrick found that he liked his reflection more now, a goofy grin becoming his default expression.
Hebe smiled broadly. "We have different options. You can go back to your family as an adopted son, go home as the born son of a new red-haired family, go home as a very changed Derrick who your friends won't recognize, or even stay here as a member of the staff. There are many things you could do here, some simple and menial, others more pleasurable if... shall we say, physically demanding."
"Do I have to decide now?" Derrick found his new shape appealing, but the options were pretty drastic.
"Not at all. You have two weeks to try any of the options. At the end of the two weeks, you will have to decide if you want to make this permanent, or go back to your former self."
