29 [M4F] Edging and Spanking

My Stepsister [M18] [F20]

My Sepsister

When I was 18 my mum got together with a guy. He moved in with us along with his daughter who was about 2 years older than me. My mum and this guy were so into each other that they went out together almost every night leaving my stepsister and me alone at home. We simply ignored each other. I spent each night in my bedroom and, after any work from school, I would lie on my bed wearing only a t shirt listening to music through my headphones. I have to admit that I masturbated at lot at that time and I became skilled at using my fingers to keep myself as hard as possible for as long as possible without cuming. My challenge was to last longer each successive night and I actually kept notes of how long I lasted. Then one evening my stepsister came into my bedroom. I didn’t hear her open my door and come into my room because of my noise cancelling headphones. The first I knew that she was in my room was when she sat down on my bed. She could see exactly what I was doing and seemed pleased to have caught me. She warned me that she would have to tell my mum and her dad. I pleaded with her and eventually as a compromise she suggested that she could punish me herself. I was happy to accept anything rather than have her tell my mum and her dad. She told me to roll onto my front and then pushed a couple of pillows under me raising my bum up from my bed. She then started spanking me with her bare hand, each spank seemed harder than the last, and she must have carried on spanking me for something like half an hour. There was an instant sting each time her hand made contact with my soft skin followed by a burst of intense pain. When she stopped I was left with a beautiful warm feeling throughout my body and a super hard erection. I had never felt anything like it before and for the first time I felt really connected with my stepsister. She pulled away the pillows and lay down alongside me and held me tight. I felt totally hers. I told her about my challenge and she laughed and said she could help me. She suggested that she use her fingers and hands and tongue and mouth to keep me hard for as long as possible on condition that I was never to cum without her permission. In exchange for her help I was to allow her to spank me whenever she wanted. This seemed like a win win for me and I readily agreed. Every night after that she would come to my bedroom. The way she used her fingers and hands to get me super hard was amazing and the way she ran the hot tip of her tongue along the length of my cock and around the top and then sucked the whole length deep into her mouth made it really difficult not to cum. She tired of spanking me with her bare hand and brought along a thick leather belt to use on me. I loved how that thick leather belt felt as it made contact with my soft skin. The pain was much more intense and felt deeper than when she had used her bare hand. I was left with an even more beautiful warm feeling after she punished me and felt connected with her in an almost Spiritual way. I was without doubt totally hers. Now I’m trying hard to find someone like her !
