Sleeping with aunty in a sari

I knew that she would not mind also. Having that confidence in my mind, I slowly crawled on to bed and slept besides her. She was sleeping on her back straight. I turned towards her and slowly kept my hands on her soft long tummy. My hands now were slowly moving over her tummy. I had to be careful not to wake her up. I was feeling her stomach, its softness and started to press it gently. My erection was very tight. I reached her navel and put my one finger inside her plump fleshy navel. I lay there motionless enjoying it for few minutes. After sometime I moved my hands a little below her navel and cupped the protruding belly and started rubbing it slowly. I was doing all this very very slowly step by step enjoying myself and also taking care that my aunty does not get up. It was a heavenly feeling for me, and a dream come true, which I had never thought off. My aunty was in deep sleep. At this moment, I felt like moving my hands a little below on her pussy and just feel it. But suddenly the younger son sleeping besides my aunty started to cry.
