This goes back some time with my late Mistress , we met at work and she loved to tie me up and share me with her friends , on this occasion I was tied up by her and she left the room quickly ,nothing unusual there. I then felt he fingers twisting my nipples and nails scratching down my body.

I was building in sensitivity and getting desperate for her to touch my cock but she avoided this .Then I feel her start to bite my nipple and hear her voice at the same time , I freeze realising its not her biting me I feel the hand of my unknown tormentor grasp my balls and squeeze and biting down on my nipple once again.and just as soon as all this started it stopped and I was left tied there.

A short time later Mistress released me and I asked who it was ,but she would not say she said I would find out soon enough. A few days later her ex mother in law is over for a coffee when I come home ,she just smiles a knowing smile and asks if she gripped to tight and laughed . Now I realise it was my Mistress 68 year old ex mother in law who was biting me and Gripping my balls hard that night. Would life be the same again.

If you like this feel free to message and I.will share more of my experiences with you.
