Wendy & Sam were talking as they walked along, Sam couldn't take his eyes from Wendy's tits as every now & then he would get a glimpse oh nipple. Abou... half an hour into their walk along the track high above the river the ground suddenly gave way beneath Wendy's feet, before Sam could react she was gone down the steep slope where she ended up half way down on an outcrop which stoped her going all the way to the river. Sam could see her but she wasn't moving, he managed to scale the hill down to. My jaw dropped as my mother unzipped the back of her sundress. She shrugged out of it, her round breasts constrained in a white bra. She wiggled out of her dress, her panties matching snow. I shuddered about to see my mom naked for the first time. I couldn't believe this. Would she let me fuck her?It was incest.She unhooked her bra, her breasts spilling out round and swaying. Her nipples were hard, thrusting pink from them. I grabbed my own nubs, twisting them as my mom wiggled out of her. We had a great sex life even in our mid thirties and we had both been each others first partner but change was coming.It started out simple enough; she would grab my balls while we were playing and squeeze them until I said I give and then she would get me off. Eventually she started playing with my ass while she stroked me and one day while sitting on my face and holding my sac she put a finger inside of me, just for a bit. The next time she fingered me for a few minutes and then fucked me.. "That's not the Polly I know Tommy" she said softly, "We'll leave her sleeping and see what she's like when we get back, that is if you're coming to help me with the furniture are you?" Yes of course I will, do you think she'll be ok though?"Dashing into the bedroom, she threw off the fetish gear and pulled on a tee shirt and skirt, with trainers, even panties too, I noticed!"She'll sleep through an earthquake Tommy, believe me, look at her now" Come on then, let's go" I said and took her.
