Chapter 6565 My Crazy Kinky Grandmother(Incest/Taboo Sex):>Ep12

'Occasionally,' my grandmother admitted. 'At first we were at it like knives, every chance we could get. But then she got married and you came along and we toned it down a bit, once a month or so, and that went on for years. Right up until your dad left, and then Ruth seemed to lose interest in sex. We probably only did it a dozen times after he left before I went to France.'
'I can't believe it,' I stuttered. 'All those years when I was growing up and you and mum were... having sex together!' I was still ragingly hard. 'Was it just fingering?' I asked.
'At first, yes. Later on we used our tongues as well as our fingers and we experimented with toys, too. Funnily enough we didn't kiss each other for a long time. I think both of us thought that was a step too far, which is crazy when we were licking each other's pussies.'
