kirsty and mum

I had only just started dating my girlfriend Kirsty when we went to meet my family. Now kirtsy is 5 foot slim and lovely 38d breasts and the day i met her i knew i was going to spend my life with her. So we set off to my parents home it was only a short drive and i sensed Kirsty was nervous about meeting my family. Rubbing her thigh and assured her that my mum didn’t bite and it would all be ok. We pulled up outside my mums bungalow and i gave her a long deep kiss and cupped her breast in my hand and gentle caressed it through her top and bra feeling her nipple start top get hard pulling away “stop i can hardly meet you mum with hard nipples can i” she giggled. We got out the car walked down the path and were welcomed by my mum and sister at the door.
My mum is in her late 50s about 4’9’’ and slightly overweight but with massive breasts and my sister is 5’6’’ and slim with firm breasts and a nice arse. We said our hello’s at the door and went into the hall which led to the kitchen at the far end of the house.
“Kettles on who wants a cuppa” mum said. So we all settled down and chatted for a while mum and Kirsty were getting on really well when mum suggested that Kirsty might like to try some summer dresses on as she was looking a little hot in her jeans and top. So off they went down the hall to mums bed room which left me and my sister chatting. My sister said she was going to the shop and did i want anything which i didn’t so we called out to mum and Kirsty and asked if they wanted anything and got no reply so i went down the hall and tapped on the door and asked again and got a definite no so i walked away and let my sister know.
she went out and left me on my own i heard her car start and pull away and thought to myself how short mum and Kirsty had been so i crept down the hall and could here giggling coming from the bedroom. I knelt down to try and see through the key hole but something was hanging in the way so i crept outside and looked in through the window.
