Babysitting Justin (Mb,nepi,toddler,diapers,cumshot,ws,scat) by Full Diaper AUTHOR'S NOTE: This story is a work of fiction only! At first I wasn't thrilled about the idea of watching my little brother Justin for the whole weekend. It didn't seem fair that my parents got to go out and have fun while I was stuck with this diaper messing machine. But then again, I figured it would be good bonding time, being that I hadn't gotten much chance to play with him since I got back home from college. At one and a half, he was starting to be on solid foods and was in the early stages of walking. He had cute blonde hair, puffy cheeks, and a bladder like a firehose. My parents left at 8:45am. This means that I would be left to deal with the dreaded morning diaper. That's always the fullest and now that he's on solids, often times the stinkiest. I woke up at 8:45 and did my standard morning routine. Made coffee, booted up my laptop, and turned on the TV. At around 9:00 I decided to check on my little brother. I looked into his crib. "Hey there Justin!" I said as I picked up my smiling brother. He didn't seem too bothered by the mess in his pamper, so I figured I shouldn't address it at the moment - even if it did sag a little. My parents had encouraging me to help him walk. Being that he was still in the beginning stages, progress was slow. The first thing I did was to sit down on the couch with him on my lap. " "Wow! Quite the load in there, huh buddy?" I said, as I felt the diaper lay on my lap. I looked at him. "Better hope those pampers are actually extra absorbent." I said as I felt the warmth from his bloated diaper. I put my finger on Micky, who was imprinted on the front of the diaper. My finger sank inwards. To my surprise, my dick began to stiffen. "Wanna walk?" I asked, as he babbled back. I placed his feet down on the floor as they began to support him. I held his arms above his head. "You got it little bro." I said, as we inched our way across the living room. He kept falling every couple of steps. But before long, he began to fuss. "Guess it had to happen at some point." I said, as I picked him up with my right hand supporting his upper body and my left on his drenched diaper. We walked to the changing table in his nursery. I kissed his cheek. As we walked, I saw his face tense up and then release. I felt the diaper vibrate. "Lucky you're a cutie!" I said as I kissed his neck - causing him to laugh. I laid him out on the changing table. Slowly, I undid the tabs and feared what lurked below. The smell assaulted my nostrils. No wonder he couldn't walk. He had an extra 3 pounds in water weight! I slid the diaper out from under him. As I did this, I felt the warmth of his mess and mushed it around in my hands. It was surprisingly heavy. I felt my penis get solid as a rock. I took a wipe and cleaned his butt. With slow and deliberate wipes, his butt was finally clean. I took another wipe and wiped down his tiny baby penis, which was covered in poop. As I slid the new diaper under him, I whispered to him... "My turn for some fun." As I placed my legs between his soft baby legs. I put his legs together, as they sandwiched my dick. Slowly, I jerked myself off using his legs. He didn't seem to mind, and in fact, was enjoying the rhethmic stretching of his legs. "Just a few more!" I told him as I felt an intense load coming. I slowly increased in rhythm until I released six shots of hot sperm onto his chin and neck! Shot after shot came out of my dick, as the white goo covered his neck. I took another wipe and cleaned him off. I put the new diaper on and secured the tabs. I put him down on the floor and placed a pacifier into his mouth. "All clean." I said as I went to clean myself up. A few moments later, my parents called. "How's Justin?" they asked. I happily replied "Great." THE END Comments?
