So my wife’s mother is only 17 years older than us and has a fantastic pair of tits. When we were all on holiday together a long time ago, my wife left the poolside to take our daughter up to the room for a sleep. Her mother who had been covered up in her one piece swimming costume all holiday suddenly removed both shoulder straps to “apply some sun cream”. She did do this but then exposed her right breast, her very large white breast and erect nipple. This was something I’d wanted to see for years. She saw me looking and immediately covered up, pretending it was an accidental slip!!!

I’ve had that in the wank bank for years now and can never forget how fantastic that sight was.

Nowadays she lives on her own but occasionally asks me for odd jobs around her house to be done. I of course oblige to keep my wife and her mother happy but I always go to do the jobs wearing no boxers and grey sweat pants or tightish jeans to show her the outline of my cock. I always catch her looking which then turns me on even more. When I’ve finished the job she always gives me a long hug and as I have move my hands away from her back, always have a sneaky slide past her fantastic boobs. She’s started noticing I’m doing this and for the past couple of occasions now hasn’t worn a bra. She’s also started rubbing her thigh against my cock when she’s hugging me. I’m thinking she’s now thinking the same as me!!!!

Carry on enjoying the flirting or finally give in and fuck my mother in law to fulfill my longstanding fantasy??
