I quickly gathered my things and went to go pick up my sister whose classes are on the 1st floor of the school. As i'm walking, my phone goes off. Its my mother telling me that she is running late and will be there to pick us up in 45 minutes. I went to my sisters classroom and she came running to the door and hugged me. We started to walk through the school as we talked. I asked her how her day at school was. She replied that it was fun but she had to go potty badly. I quickly remembered where the locker rooms are and rushed her into the boys locker room which was empty. We entered the shower area and that's when I realized I had been holding in my bladder all day too. I told Jenny that I had to go too and proposed that we just go in the showers. She did not object and we both stripped off our clothes until we were both standing there naked in the locker room. The sight of my naked sexy little sister turned me on and I began to get an erection. She quickly caught on and asked why my wee-wee was hard. I had to explain to her that it happens when boys get excited. I then laid down on the floor of the shower and my sister looked at me and asked me what I was doing. I told her I wanted to play a game with her. She giggled and clapped her hands and did as I told her. She squatted her butt so her stream would fall on my erect penis. She struggled for a few seconds but then came a long hot flow of her pee and it felt great. I then told her I had to clean her and she laid on the floor next to me in the showers. I then positioned us in a 69 position and told her to suck my wee-wee like a lollipop. I began to eat out her hot tight cunny and tasted the leftover salty drops of pee. I tonguing her faster until i heard my sister say she felt like she needed to pee again. I felt her cunny contracting around my tongue and I felt my orgasm building. I warned her I was about to release a special kind of pee and to swallow it all. Afterwards my sister caught me off guard with a question. She asked me how babies are made and that she had seen daddy with his wee-wee inside mommy's cunny in bed a few nights ago. I then told her we should go somewhere more private because I knew the janitor would be arriving shortly to clean the locker room. I took her to the bathroom part of the locker room and locked us in the handicapped stall. I laid down on the floor and picked up my sister and set her down on top of me just below my balls. I then told her I was going to show her but it might hurt. She nodded her head and I picked her up and I guided her above my hard penis. I told her to grab my wee-wee and guide it into her cunny. She was hot, tight, and amazing. I showed her how to ride up and down my wee-wee like a horsey and it felt great. I then grabbed her by her hips and guided her even faster on my cock until I felt my hot seed erupt and fill my sisters cunny. She said she had fun and enjoyed it. I got up, unlocked the stall and took my sister to the showers. I took out the soap from my bag for gym class and turned on the water. I gave her the soap and told her that we were going to play another game and bathe each other. Jenny washed my back legs and stomach and arms. I told her she didn't get all of me and she blushed and took the soap and washed my limp penis which quickly became erect again. She handed me the soap and I washed all of her and saved her bald tight cunny for last and fingered her. She enjoyed it and asked me not to stop as she moaned and climaxed. We turned off the water and dried off and got back in our clothes and went outside to the carpool lane where our mother was waiting on us. We got in the car and she asked us how our day was at school. Jenny and I looked at each other and said it was great mom!
