"Um..." I said uncertainty. This was all so strange. "I don't know... It's easier if you decide for me. You are the boss after all."
"Ah, I see. Yes, some types of people do feel most comfortable with someone else in control of them. Is that what you want?" I blushed and looked down.
"Ah, I guess..."
"Can't even make up your mind for something like this, hu? But just you know, if you want me in charge, I'll be in charge for the whole business trip. No cold feet, got it. This is your last chance." My heart was racing as I nodded. "Okay then. Let's go back in for another few minutes. You stay in there until I say you can leave." The way he commanded me got me all excited. I entered the rejuvenating mud-bath just as instructed and let it cover me.
After about five minutes, my boss ordered me to get back out and rinse off. I obeyed as promised and was excited to see how much I'd changed this time. To my astonishment, I had regressed another 3 years. Maybe more. When I had been this young before, I'd had braces and some acne, but not now. I looked delicate and perfect. It was strange being this short. My boss hadn't changed that much. He looked to be in his early 40s now. He examined me closely, which made me blush again.
"Almost perfect," he said, taking me back to the mud-bath a third time. However this time, he didn't drunk me under, but instead scooped some of the mud up and covered my crotch. It tingled strangely and it felt weird to only be regressing that one spot. After several more minutes, he made me wash off again. My already small penis had been shrunk even further. It was way too small for someone my apparent age, and definitely too small for my actual age. My boss' cock on the other hand looked huge, angry and hairy. It had grown erect while inspecting me and looked very intimidating. He didn't make any excuse for it or try to hide it in any way, and I could not take my eyes off it.
The person at the reception offered us a menu of new clothes to select from, but my boss didn't let me see it. He made all the decisions for me. It excited me, knowing that he'd decide how I'd dress.
For himself, he'd chosen rather normal clothes, fit for this warm weather. A pair of shorts, sunglasses and an open shirt. For me however, he presented me with a pair of super thin short shorts. They were as tight and thin as a girl's bikini, and he gave me no underwear to have underneath. Luckily for me, and also embarrassing for me, my own dick had shrunk to small that it was barely visible through the thin material. Mostly it served to emphasize how little I had between my legs. The shorts rode up my crack a bit, emphasizing my butt as if the shorts were painted on. They were so short that the inside of my pockets poked out from the underside.
I was then given a tight, black tank top that was also practically painted on me, and finally a short, sleeveless vest on top that didn't cover my mid-rift and matched my short shorts. It all looked rather fashionable actually and was very comfortable. The look was finished off by a few accessories. A thin black cocker. Some armbands. And a pair of flip flops as the only cover my exposed legs got.
Lastly, the lady behind the counter asked us how long we'd want our changes to stay.
"If you don't take any pills, you'll age about one year per day until you're back to normal. We have pills that can change that. Taking a blue pill will keep you from aging for one month. After which you'll start aging one year per day again. Taking a green pill will return you to normal within a day. Most people like to take a blue pill first, and then swallow the red pill after a few days to return to normal in just an hour or two. Though some clients have chosen to stay young for several months in a row by taking a blue pill every month. Though if you chose this, I must warn you not to overdose. Taking two blue pills back to back risks making the change permanent and you'd have to age at a normal rate in order to grow up again. The green pill will not work then. Taking three pills back to back is very ill advised, cause it will stop the aging process completely."
"I understand," my boss said. "Boy, go outside and wait for me." I felt my heart racing. Did I really want to let my boss make such an important decision for me? I swallowed hard and obeyed him, waiting anxiously outside the spa and looking in through the window. I couldn't hear what they were saying or make out what exchange was being made. I realized I'd forgotten to get my phone and wallet and adult clothes, but I didn't dare reenter the spa against orders.
My boss came out shortly later. "Um, I forgot my stuff in there," I said.
"Don't worry about it. I told them to send it all to our hotel. Now here, swallow this."
