I'm not sure this erection counts as spontaneous as I knew exactly what we were about to get up to in the change rooms.The Married Guy and I hadn't fo...led around in a while and he had told me before that he was super horny.When we entered the change rooms, I headed straight towards the disabled shower, it is bigger than the usual ones and is at the end of the row. The Married Guy checked that there was nobody else in there, threw his towel on his bag and headed down to join me. I had the water. She was walking quickly but came to a sudden stop when Olivia emerged from Dave's room and grabbed her arm. Olivia had Dave's shoes in her hand. Olivia turned Molly to face her and looked in her eyes. Olivia nodded when she saw the blank expression."Molly, I am going to give you orders and you are going to follow them. If you do not, I will torture you with both pain and pleasure for the rest of the night. Do you understand?" Yes."Olivia spun Molly around so quickly Molly didn't know what was. But the first half won as her giggles were muffled as she took him deep in her mouth.She sucked him quickly, her hand on his shaft as her teeth grated along his length, her lips leaving smears of red lipstick behind. He bit his lip, trying to stifle his groans of pleasure as her hand and mouth moved as one, her hand keeping perfect time with the bobbing of her head. His cock was rigid, throbbing in her hand and mouth, his balls tight in her other hand.He came almost without warning, his cum. Jerky boy...toy with that little twig you call a cock.”I was not much into humiliation but the confidence my wife displayed mesmerized me and I felt compelled to comply with her command. I scrambled to my knees and grabbed my bulging bad boy jerking away as I gawked at my sister in law, skillfully taking the entire 10 inches inside her mouth allowing my wife to fuck it in and out now banging her throat.My wife was really getting into her role as she grabbed hands full of Tara’s hair and fucked.
