I was soon moaning and writhing on the bed as I worked my clit with my finger tips and pushed the firm rubber dildo in and out of my cunt. Tanya got o...f the bed suddenly and went back to the cabinet. I slowed my rhythm and watched as she returned with another dildo, attached to a harness. Stopping by the side of the bed she stepped into the harness and was soon sporting a huge strap-on cock. ‘I want to fuck you.’ she said, climbing between my legs. I spread my thighs and reached up to fondle. She took her top and bottoms off and was in her bra and knickers. I could feel my cock getting hard through the towel and I’m sure she could feel it to, though she resisted touching it with her hands. I expertly unclasped her bra to reveal her breasts and she had lovely small nipples which I sucked on, which made her breath harder. I pulled down her knickers and slid them down her legs. At this time, my towel slipped away and my cock was touching the front wall of her pussy.I parted her legs so. The picture of the larger woman on her knees between her lean, widely-spread thighs almost made Tina cum.It almost made Jane cum too, and Ari was looking paler by the minute as her sister's lustful thoughts flooded into her mind. With great control, Ken felt Ari clamp her mind closed. Amusingly, she equated it to closing her legs to keep someone out of her pussy."You know? Jilling off? Masturbating? Playing with..." I get it Tina," said Ari in a sharp voice. And boy did she ever. Ari was having. Your sphincter is gripping my cock by the tip. Your brother is holding still to allow me to gain full entry into your ass hole.I slowly slide it inside until I can feel my balls touching the base of your brother's cock. We begin to alternately fuck both of your orifices. First I plunge inside and then your brother pulls out. The he plunges in as I pull out so that your anal sphincter grasps and milks the head of my cock. We are plunging in and out of you like the pistons of an engine.
