The next morning when I dropped off my daughter at the school only Ruth was waiting for me. She was leaning rather seductively against the fence wearing the tightest, whitest pair of knee length lycra shorts. 'No Chrissie' I asked, 'No, her youngest was unwell during the night, so I brought her son to school'. We ran off down the path and off on to the woodland trails. It was wet under foot but not raining. We did not talk while running and it was strange not to hear the usual giggling of the two girls. When we reached Ruth's gate I just followed her in, no discussion. Once in the kitchen we removed our shoes and she made drinks. We went into the lounge and sat opposite each other, conversation appeared difficult. I asked if she thought Chrissie's child was really ill or was she avoiding seeing me after yesterday. Ruth said she thought the illness was genuine but said she had been surprised by how much she wanted me to 'make love' to her yesterday. She repeated that she did think she wanted to go all the way herself. I said I was also surprised as previously she had not even been as flirtatious as you, flashing your pussy at me in the garden. Ruth blushed and covered her face with her hands, peering through her fingers at me she said 'that was so unlike me when I did that, I was just so aroused knowing the affect my skirt and pants was having on you'. 'Chrissie and I had wound ourselves up into sexual excitement talking about you and running in the woods with you'. I replied that it had certainly had an affect on me and I anticipated that you would be the one I might end up shagging. Chrissie seems nervous and rushes off, I had been very shocked in the shower but had to go for it. Ruth said she did not know Chrissie well only as another mum she chatted to. Until very recently they had started stopping off for tea at each others houses and nattered about children, school and recently you in your running shorts. She said Chrissie's husband worked away for long periods of time, I think she gets very frustrated and then excited when he returns. I suggested we had the same problem as our partners are away for long days during the week and weekends are so short and often un-satisfactory sexually. Ruth suddenly leaned back opened her legs and stroked her pussy through the lycra of her shorts, 'I do get very frustrated and these last few days have been very exciting'. I slid off the sofa and crawled across to her and planted a kiss in her mound. It was very warm and she responded to me by holding my head in place, so I kissed again and nuzzled my nose into her body. she squealed and rolled her hips under me. She let go of my head and started to remove her shorts. They did not come off easily so I tried to help and eventually pulled them down her legs, her pants came off as well. I pushed my face into her waiting pussy, it was warm, wet and smelt beautiful.
