Even before they had arrived back at Uncle Mack’s flat Alia had taken him in her mouth and the girls were swapping his pre-cum over the back of the ...assenger seat. Tee was being a complete prick-teaser, flashing her bare pussy on the back seat, running the tip of her tiny vibrator over her hard clit.“Can you stop for some new batteries please Uncle Mack – I might let you insert them if you’re good”.“Slut” said Alia, clambering into the back seat when they stopped at the petrol station for fuel. She had long blonde hair, big natural tits right out of a 70's porno, and an ass that was made for swallowing cocks. I later learned that she was forty-eight and that her husband spent six months out of the country for business, but all I was thinking about when I saw her was how I was going to get inside of her. I was the last weekend in August, so it was perfectly acceptable for someone to be out in a bathing suit and not be trying to lure the young hunk across the street over, but I took it. From the angle of the camera and from Mary's angle it was very clear that Sally was naked under her sundress. I could see her lips, her small bush, Mary was staring at Sally's hands and like me at Sally's open crotch.I was fascinated by Sally, she sat there so calm, she had her legs open her hand moved down to her exposed pussy, she made no attempt to conceal what she was about to do. I could see Mary watching her as I was. Sally asked "have you ever watched a woman finger herself to a climax. Well, as much as she could. She slowly started sliding her hand up and down, just like she'd seen her mom do to her dad.Midnight seemed to like that, so she kept going. And, as she stroked her horse's dick, she felt her young, barely teenage pussy getting wet. She unbuttoned her riding pants with her free hand and slid her fingers inside her white, cotton panties.As she worked two fingers inside her wet little cunt, she realized that she wanted to taste her first cock. This cock that she was.
