Two days after my seduction by Grandma we were watching TV in the evening. In reality, we'd had a problem with concentrating, so after ten minutes she switched it off. We sat side by side on the sofa, each of us seated on a bath towel. Nan was partially lying on my chest, my left arm draped around her shoulders with my hand inside her nightie as I caressed her breast and played with the nipple. The towels were to protect the upholstery as we pleasured one another. My fingers - all of them - were inside her pussy while my thumb teased her clit. Nan's hand was doing all sorts of wonderful things to my cock, wanking me for a while, then sliding her fingers with tender care over the head, massaging the dribble of pre-cum into it. She was an expert, regularly taking me within seconds of jettisoning, but always being careful not to over excite me so I didn't climax. I wore a t-shirt and nothing else.
I'd been in this state of blissful stimulation for an hour or more, Nan had persuaded me to experience constant arousal instead of being in a rush to climax and I'd soon understood why. The feeling of a continual hard on was incredible.
Nan had managed to keep me from coming, whereas she had lost count of her orgasms. I'd discovered her G spot. Didn't know what it was at the time, but knew what it did for her. She cried out each time she had one of her multi orgasms and yet another gush of cum spilled onto my fingers. I would have been happy to work my fingers into her sopping wet hole all evening, but she stopped me.
'Enough, Bobby. You've exhausted your gran. Let me rest for a few minutes.
'Ok, Nan. I have to rest myself.' My cock was so hard through her continual attention it was a little painful. I needed relief. 'Why don't I cum into your pussy ... or even better, your mouth.
Nan had no time to respond as there was an interruption. We were in the lounge which led to the back garden. It was a wonderful warm evening, the French windows were open and we enjoyed the soothing background of Summer sounds as we played. It was then Nan's next door neighbor arrived.
Mrs Dyde stood on the threshold. 'Oh my!' she said.
'Connie,' said Nan. 'Come in.'
Mrs Dyde entered the room with a horrified expression. 'I'm sorry, Ethel. I didn't mean to disturb you while you were ...'
Nan was unfazed as though the tableau her neighbor witnessed was normal. 'Can I help you, Connie?'
Mrs Dyde was finding it difficult to concentrate her words as her concentration was fixed on my erection. 'I heard you ... groaning and thought you were ... unwell.'
Nan laughed. 'On the contrary. Thanks to my grandson's expert fingers, I'm extremely well.'
That was when I came to my senses and jumped up to leave the room.
Nan pulled on my hand. 'Stay where you are sweetie. Connie's seen a prick before.'
I sat down. Would never dare argue with Nan. I looked at Mrs Dyde. She was older than Nan, but more attractive. Normally, she dressed formally, regal would be accurate, but it was hot, so she wore a dress with a floral pattern which buttoned from top to bottom. The skin between the V of her dress was flushed with passion. It was a giveaway I'd noticed around Nan's neck when she was on heat.
'Move over, Bobby. Make room for Connie.'
'I ought not, really I didn't mean to disturb you.' Despite that, she squeezed between us and sighed. 'Ethel, how many times have I told you my name's Constance. Anyway, be that as it may, you well know I was married, so of course I've seen a ... seen a penis.'
'It was a few years ago that Albert died, 'Nan told me. 'And she couldn't have seen it that often since Connie always wanted the light out.'
'Ethel! I do wish you'd keep such information to yourself.'
'Connie, to make amends for my indiscretion I'll share my grandson with you.' As she spoke, she picked up Mrs Dyde's hand and used it to stroke my cock. 'Bobby's prick is so soft and smooth, yet hard at the same time. Don't you agree?'
