I didn't last long. With my right hand reaching round Chrissie's body and rubbing her clit and the left against the wall for support. Ruth was still climbing on my back and rubbing her pussy against me. I came hard. Chrissie was screaming with pleasure and pushing her bum back into me. After a short while we all stood up, Chrissie turned and hugged me, we moved back under shower spray and she washed her crotch in a rather clinical way rubbing the shower gell in furiously. It was not very sexy and appeared to be trying to remove evidence. She said she had to go and Ruth pointed her towards a pile of towels, I also started to move out of the shower but she held me back. In a minute Chrissie had dried herself and gone. Ruth pulled me to her and we kissed, my semi-stiff dick was stirring again, she slid down and placed it between her ample boobs rubbing up and down. I did not come again even when she licked to tip and took it into her mouth briefly, She turned off the shower and we dried ourselves looking at each other. Ruth put on a dressing down and disappeared downstairs while I put my wet shirt and shorts back on. Back in the kitchen she had made more mugs of tea. We sat talking about what had happened, she said she was enjoying our running and what had happened but she was unlike Chrissie not sure she wanted to go 'all the way'. She said that our few days of fun had made her very aroused and she had seduced her husband twice this week as soon as the children were in bed. He had been very shocked as they generally only make love at weekends as he has to be up early to catch the train from Basingstoke Monday to Friday. 'What time train' I asked, about 7am she replied. My wife catches that train I wonder if they see or even know each other, same station, same train at the same time. I admitted that my wife and I had also had unusual mid-week sex. .
