Brother sister childhood incest

My story revolves around since childhood and not for some particular day or months. I and ny brother who is 4 years younger to me were always close. We slept in same bed with same bed. Earlier we slept on sofa cum bed. I have seen my brother sucking mom's boobs even after he was grown up to 2-3 years. He would end up touching mom's boobs and mom would allow him to suck and touch. I always wondered him to suck my boobs but i was just in growing stage but that scene always on my mind. My both parents are working so we stayed home alone most of the time. Mom used to be back by 4pm. I and my brother often slept hugging eachother and i have taken bath with him together in bathroom. When i was around 7-8th std i knew about porn and puberty grew in me. I would often as usual hug my brother and sleep but he would try to touch my boobs while I'm in sleep. I would get offended but over time i loved him touching my boobs. Afterall by this age he couldn't get mom's boobs as he was a grownup boy studying in 3-4th std. Slowly i would often remove my bra and sleep and enjoy him touching my boobs and i often used to get wet pussy. Lucky never our parents found out. This was the time i would often ask my brother to bath together and told him not to tell parents or else they would scold. I loved bathing together and seeing his erect dick. Because i could always feel his erect dick while he used to hug me and sleep. I let him touch me everywhere while bathing and press my boobs with his soapy hands. I often stroked his dick and he enjoyed alot..he never knew of sex by this age. But since it was pure pleasure i loved rubbing his dick over me..over my boobs and over my ass. Which i often encouraged him to do. While sleeping i would take his hand of let him touch my pussy and rub my wet over his hand. He would often ennd up sniffing and i know he got attracted. I even used to stroke his erect penis under blanket. I have tasted his cum after it was ejaculated on my fingers and while bathing as well since he used to ejaculate over me my boobs. We had a habit of going to pee before bed. So i knew he had often touched my pussy at night with slight pee. I know it's wierd but that's same with me as well. Due to some excitement i have touched his soft penis just after he came from washroom and he last drop of piss on my fingers and have made that dick erect as well. I often made his kiss my neck and suck my boobs because that's what made me more wet. He personally loved sucking and pressing my boobs and sniffing my pussy or his fingers after touching me down there. I had seen alot of porn and wanted him to force his dick inside my mouth but since he was young he wasn't that dominant. While bathing i let him freely sniff my pussy either with his fingers or directly. Over time while bathing i took his dick in my mouth and gave a slow moment. He loved it soo good and he ejaculated his whole load in my mouth. He had always a thick cum. Initially i used give him blowjob only while bathing. But over time i got attracted to his dick smell and even used to give him blowjob under blanket with probably his few piss drops. He is the only guy to whom i have given blowjob with piss drops in my mouth
