While mum was voluptuous she wasn't tall, about 160 cm. I stopped roaming over her bottom with my hand and began to explore in a more serious fashion. I ran my hand along her lower buttock and slowly worked upwards towards her crevice. Her hand, the one that was running over my chest and stomach, slowed its pace a little. By now I didn't think she would suddenly change her mind and back out but I wondered how far we would be willing to go. I doubted she would want to have sex with her own son and wondered about how far I would go- I was enjoying this hugely but thought it was one thing to touch your mum like this and a completely different matter to have sex with the person who gave birth to you.
I edged my hand slowly between her cheeks because I wanted to savour the moment and because I wanted to slowly heighten the pleasure for mum. With the thumb edge of my hand I could feel the slight deepening where her cheeks dropped away to her anus and as I pushed my hand in further I could feel the smooth texture of her skin change and the increased heat from the skin around her opening. I wanted to explore her bottom more fully but thought now wasn't the time.
I shifted my position slightly so that I could reach my hand further down and touch her vagina. I didn't want to make some half-hearted attempt to reach it from where I was and grope her like an over-excited teen. Rather I wanted to be able to slowly work my way inwards in as sensual a manner as possible. As I continued to stroke the soft skin where her thighs widened she stopped stroking my chest altogether and instead pressed her hand down gently but firmly. I could feel the increasing warmth as I got closer to her vagina. When I felt the first of her pubic hair I ran my hand down her thighs towards her knees. I had to stretch to do this and mum accommodated by edging up the bed towards me. She parted her lips and softly gave me a sucking kiss on my neck.
I continued stroking her in this teasing manner for some while. Each time I pressed my hand in towards her vagina I could feel the heat, more hair and then the dampness that became wetness as the edge of my hand moved towards her lips. She still lay motionless except at one point where she arched her back slightly and pushed her bottom out to make it easier for me to continue between her legs.
It was heavenly when my thumb touched between her lips. I loved this with anyone- the pleasure you have to have from someone to be so intimate with them, the trust and willingness to do it. My penis jolted under her thigh as I felt how wet she was and how easily her lips parted. The heat was extreme and the skin was now incredibly soft and pliant. I couldn't stop myself from pushing my thumb a little way further inside her and loved how the well lubricated lips parted to accommodate me.
Mum pulled my face down towards hers and kissed me forcefully, pressing her lips hard against mine. I continued moving my thumb back and forth inside her entrance, thrilled at how easily it parted the folds of skin and how wet she was. She pushed her tongue into my mouth and gently ran it around the inside of my lips and across my teeth. I let her do this, as it felt like she was exploring my body like I was hers. I couldn't believe this was happening- that I was able to touch mum in this way never mind her very positive response.
