I was 22. Mel was 40. She was my girlfriends mum. I had been going out with Julie for a few months. She had lost her virginity to me and we were spending a lot of time together, often in bed.
She was going away for a sports tournament and I had arranged I would go around to her house and help her mum cut some trees down at the weekend.
I went around and we finished the job and decided to have a swim in their pool to cool off. Mel went to get changed and to get some towels and I took off my tshirt and boxers and jumped in in just the shorts I was wearing. About 5 minutes later Mel came back out carrying 2 towel and wearing a bikini that left almost nothing at all to the imagination. It really was struggling to hold her tits in place. She dived in the pool and came over to where I was and asked if I liked her swim wear. Very much so I said. Then she moved so her back was to me and said she had a sore neck would I mind rubbing it for her. I wasn’t stupid and suspected where this was heading. I started rubbing her neck and she’s reaching around rubbing my crotch and my cock is immediately getting hard. What’s happening down there she asks. I’ve now got my hand down the front of her bikini bottoms and are fingering her pussy. I say we shouldn’t be doing this. Her reply was I know but I’m not going to tell and I’m sure you won’t.
We quickly got out of the pool, semi dried ourselves and went into her bedroom where we spent most of the rest of the weekend. She was insatiable.
For the next 6 months I fucked the 2 of them, occasionally on the same day. I’d often go to Mel’s at lunchtime or when Julie was at sport and to this day I’m sure she had no idea her mum was also fucking her boyfriend.
