Very loosely based on something a friend told me happened to him and his wife.
-------------------------------------------------
"On your own this afternoon?" I asked, letting myself in through the back door.
"Hello there. Yeah, all on my lonesome," she replied. "Fancy a cuppa?"
"Yeah, that'd be nice."
"Hang on, just need to give the dishwasher a tablet," she responded as she smiled, and turned her back to me. Leaning forward from the waist she opened the under-sink-cupboard and started looking for the dishwasher tablets. I could see, thanks to the tightness of her shorts, that she wasn't wearing any knickers beneath her shorts.
I leaned forward and cupped her left buttock with my hand. She jumped slightly, then pressed back against my hand. I squeezed her butt-cheek, then brushed my hand across her pussy to the other buttock. She jumped even more at that, and I heard a sigh. She'd stopped looking for the tablets, and was just holding still, pressing back slightly against my hand.
Taking this as a sign of approval, I moved my hand back to her pussy and ran my hand forward between her legs. I could feel the warmth, and as she moved her legs apart a little, there was a definate dampness.
My cock was standing to attention and ready for action at this point. It was clear to me that she was also ready, able and willing. I kept caressing her pussy with my left hand, whilst using my right to pull my shorts and undies down to my ankles.
When I took my hand off her pussy she gave a soft whimper, but as my hands took hold of the waistband of her shorts the whimper turned into a moan of anticipation. Sliding the shorts over her bum, then down her thighs, I caught a glimpse of her soft, wet, inviting, shaven pussy.
