About twelve years ago when I was 54 I became really close to my 15 yo adopted son. I spoiled him really rotten with material things but then through a period of time I found myself getting aroused knowing he was looking at me in a sexual way, a typical schoolboy I suppose. I had a good body so I thought why not discreetly show it off to him whenever possible. This resulted in me leaving the bathroom door open while I towelled off after showering. I knew fine well he was relieving himself from his room while watching which really excited me also. I shared the house with my two sisters and we were all spinsters so this was happening when they were out running the family business. He was a very shy boy but one day he came in offering to dry my back which was his excuse so i agreed. Immediately i could feel his excitement against my hips and became aware he had slipped down his shorts a little. I turned round and reassured him it was normal and complimented him on his figure. We then began hugging and caressing and i said we should go to the bedroom son so we did. I closed the blinds and he got completely naked with me. We then got into bed and this is where his sex education began. He was soon a fantastic lover and ended up taking me doggystyle which was incredible feeling him throbb inside me while bouncing off my hips. We slept together for eight years and it was fully consensual. We were not blood so it wasnt incestuous and i am not a paedophile. Given the circumstances that he was a good looking young man wanting to learn about sex and i was a fully mature lady who hadnt had sex in over twenty years it was inevitable so please dont judge.
