I (55)m have been occasionally fucking a similar age woman neighbor for several weeks now, we have dinner and chat a couple of times a week and sometimes finish the evening with a doggy style fuck over her couch. She has told me about her daughter who lives interstate and had previously mentioned that she was planning on visiting in the near future. From what I gathered from our conversations the daughter has recently separated from a lesbian relationship and was in between accommodation and jobs. At the beginning of this week I rolled up for our now regular drinking eating and talking appointment, it was all going well and after several hours of drinking I was preparing to leave having eaten and watched a live telecast sports event. She hinted that she would like to bend over and have her cunt filled so i went and had a piss and returned to find her naked and assuming the position. She doesn't have a great body but I've got a crook looking head so I guess I shouldn't judge. I pressed my cock onto her damp pussy lips and edged my shaft into her cunt. She does love a bit of penetrating and was soon moaning softly about how good it felt. I pumped away slowly increasing my rhythm until I had a reasonable pace up and was preparing to empty my seed inside her, she was moaning and begging to be filled. Not far off emptying my nuts, maybe 10 seconds, the fucking front door opens and a woman in her early 30s comes in. Fuck mum you could have told me you were having visitors. That's all I heard and I was a little nervous about what had just happened. She proceeded to walk past us and into the kitchen saying, don't mind me keep going, it looks like your having fun. Her mother said to me, yes, keep going i am. So having gotten over the shock i continued to thrust my cock into her and she continued moaning, within a minute i had filled her cunt and she was cleaning my cock with her mouth. I tuned around looking towards the kitchen and her daughter was standing there watching, my cock twitched in her mother's mouth as I got a good look at her daughter. Quite a good looking young woman with a much slimmer figure than her mother, great looking legs. Her mother finished cleaning me and the daughter said, gee mum you're getting better looking cock now and proceeded to walk away down the hall. Her mother apologised and i left as I'd planned. Well tonight I'm going back and as far as I know the daughter is still visiting, fuck knows what tonight might turn into.
