She instructed him how to use his large penis head lip to tease her vaginal opening sides, just inserting the head, moving it in and out, up and down....She instructed him to slide his penis head up and down between her pussy lips, took a while, but he got the knack. Then his penis flung straight forward towards her face, she laughed hysterically as a big gob of mucous landed on her chest. He asked "what's that?" She replied "mucous. Look at your penis head, there's two more big gobs of mucous. To my surprise and delight, she hooked her arm through mine as we walked, to anyone else we might have been mistaken for mother and daughter out for a stroll. Instead the truth was that I'd known this lovely young woman for less than an hour and I'd already had sex with her. As we strode along, Brigid told me a little about herself. She was twenty-seven years old, a devout Catholic who was saving herself for Mr. Right, so my lovely Brigid was a virgin. He parents were killed ten years ago on. Luckily we all liked each other and over time, it evolved into something almost polyamorous. He was over more often than not. My wife slept between us and grew used to having both of us on demand. No one got much sleep. As the weeks and months went by, our inhibitions dropped off and and we grew excited to push our limits.One night, my wife noticed me staring at her as she sucked his cock. It was mesmerizing for me to watch… especially when she locked eyes with me and seemed to revel in how hot. Grace tried to ease the situation by being extra affectionate with Walter. Unfortunately it seemed that Walter was generally satisfied with sex once a month. She tried to force the issue, figuring if she got sex from him it would dampen her ardor when she was around her son. Unfortunately the result was an even greater problem.One night, after they had all retired, Grace decided she would treat her husband special and perform oral sex. She knew he liked it but it had been years since she had.
