"Look, you obviously didn't wake up when you had to go last night. We can try to have you wear pull-ups and use the toilet during the day, but they probably won't hold enough pee for a whole night so you'll have to wear normal diapers at night. Deal?" Jim asked. Admittedly, he had a point there. "Okay." I said weakly, and he put a pack of pampers overnights size 5 and a package of pull-ups into the cart. According to the print on it, the pampers package contained 52 diapers - I sincerely hoped I wouldn't have to spend that many nights as a toddler.
As Jim steered the cart towards the restroom, I suddenly became aware that he would put a pull-up on me before letting me try on any clothes - there was no avoiding it, I'd be wearing a kind of diaper for the first time in 25 years. "Time to put a pull-up on you just to be sure you don't make a puddle somewhere here. Or do you need to go to the restroom first?" Jim asked when he picked me up from the cart. Once again I flushed with embarassment. I tried to concentrate on my bladder and bowels, but I really wasn't sure if I needed to go. "M-maybe." I answered. "Number 2 or just a quick wee?" I really didn't want to sit on a convenience store toilet. "Just pee." "Okay. I think the urinal's a bit too high for you, I'm gonna hold you in front of it." He pulled up my shirt, I pulled down the gym pants and felt really weird pointing my tiny dick at the urinal while being held by Jim. On the other hand, he didn't seem to mind at all - it was as if taking care of a toddler who was also his 28-year-old flatmate was completely normal for him. I tried to relax, but not a single drop of pee came out - maybe my bladder was really empty, maybe it was the weird situation. "Are you sure you need to pee?" Jim asked. "No.", I admitted. Jim put me down on the floor and handed me a pull-up. I tried to convince myself it was just like underwear - only thicker and with a cartoon car printed on it. When I pulled it up, it felt surprisingly comfortable, and at least I'd now be safe from any embarassing accidents in the store. The hard seat in the shopping cart also felt a lot more comfortable with a padded backside.
Finally, we actually arrived in the kid' clothes aisle. It wasn't a whole aisle, just part of it, and as we found out the selection for toddlers was limited to pink and blue sweatpants, striped t-shirts with either a pirate or a unicorn printed on them and pink and white socks. "Let's just get the boy stuff and go home." I said grumpily. "You sure you don't want a unicorn shirt? Stacy would find you really cute." I flipped the bird at him. "Okay, you're cute enough as you are." he laughed. "Still, you'll need to try things on so we know your size." He put me down on the floor again and gave me one of the blue sweatpants. I tried to put it on, but found it surprisingly hard. I managed to get my feet in, but how was I supposed to pull it up while standing on it at the same time? "I think I forgot how to put on pants. Could you help me?" I asked, and Jim squatted down to help me put it on. Luckily, it fit perfectly over my pull-up and was just the right length. The first shirt I tried on also fit, and I even managed to put it on myself, though the pirate ended up on the back and Jim had to help me to turn it around. "How do I look?" I asked. "Like a toddler in cheap clothes." Jim answered, and I tried to look as mad as possible, though he had a point. He helped me to undress again as we still needed to pay for the clothes and put two of each in the cart, "so you have something for changing if you get yourself dirty."
Unfortunately the store didn't have any real shoes, but on the way out Jim noticed some kids' slippers in a bargain bin. The smallest pair happened to be pink. "Those might fit you." he said. "They better don't, I wouldn't wear them anyway." I answered. "Come on, at least we'll know your size." He put a slipper on my foot while I was stuck in the cart, and though I tried to kick it off it obviously fit. "Great, we're buying those so you can walk home on your own." Jim announced. "Nooo!" I shouted, surprising myself with the volume of my voice. "Come on, they won't turn you into a girl. I really don't want to carry you all the way back, you're heavy!" I was about to protest again, but then I noticed how much I was behaving like... a toddler. "Okay, sorry. Thanks for caring for me." I said. "Aww, it's okay." Jim answered and ruffled my hair.
We proceeded to the cashier and Jim paid for everything. "Whoa, having kids is expensive!" he said as we returned the shopping cart and put my new clothes and slippers on. I briefly wondered who would pay for my stuff now and if I'd have to give Jim and Stacy my bank account passwords, but then I was distracted by a sudden pressure in my bladder. I didn't want to go back to the store restroom and we'd be home in less than five minutes, so I didn't tell Jim and just tried to walk as fast as I could. Before we even reached the corner, my pee started to trickle, then flow into the pull-up.
