After dinner with the family I sat down with Mom and Mariah to talk about getting a training bra. Mom hugged me and held my hand" I know it's scary all the changes when a girl grows up but you sister and I are here for you. Have you had any changes down there". She motioned to my vagina " Nothing yet mom but I know what happens I've been through puberty before it's just going to be different this time". " Well when you get your first period tell me and I'll show you how to use a tampon. They can be difficult at first". I thought about that as I walked to my bedroom and closed the door behind me.
I found my dirty clothes under the bed and pulled them out. John's cum was still wet and sticky. Just the sight of it made me excited again. I sniffed it before licking it off my shirt. I could feel myself getting wet again and started rubbing myself through my shorts. I pressed my dirty shirt against my face inhaling deeply as I rubbed myself faster, it didn't take long before I climaxed. My panties were soaking wet as I stood up on shaking legs. I put the cum covered clothes in the hamper and peeked out into the hallway seeing John going into the bathroom wearing his boxers. I couldn't stop myself. I snuck down the hall, my footsteps light on the floor. I waited until I heard the shower before quietly opening the door and sneaking inside. I silently undressed knowing what I was doing was completely inappropriate but I had to do it, tossing my clothes aside I pulled the shower curtain aside and joined my brother.
" What the heck!!?" John jumped back and covered himself. I stepped under the water feeling it running down my smaller body" what's wrong? Why are you covering yourself" John uncovered himself revealing his erection " you surprised me, why are you in here". I admired his penis water dripping from its length, his hairless balls dangling below " I want to take a shower and besides it's not like I haven't seen one before". I started washing myself with some mango scented body wash making sure to clean my crotch really well. John watched me, his penis fully erect and twitching slightly before he grabbed some soap and started washing himself.
We showered together. I helped him wash his back and he returned the favor squeezing my butt while he did. We finished up and dried off standing naked in the bathroom. I walked over to the toilet and put the seat down " you boys always leave it up" sitting down I reached down spreading my slightly and started peeing. John watched me closely " so that's how girls pee" I spread my legs wider allowing him a better view " it's a bit different than a boy that's for sure" he sat down on the floor watching me pee as I finished up and wiped myself " wanna watch me pee?" I looked at him in surprise " watch you pee? Why" he shrugged " because pee is cool". I stood next to him and watched as he aimed into the bowl and peed giggling as he aimed his penis around " having fun?" " yeah I am, I love peeing like this" he finished up and shook his penis off.
We brushed our teeth together, still naked and not caring about it. He was erect again and I couldn't help but want to grab it again. Spitting and rinsing my mouth I turned to him. " Wanna see how girls masturbate? It's really cool" he played with himself holding his penis and stroking it slowly " yeah that sounds really cool" he grabbed the lotion form under the sink and pulled on his boxers " let's go to my room" I followed him to his bedroom and we closed the door.
