My cock throbbed hard within my jeans as there was far more than a hint of her crotch now visible. I could easily see her neatly trimmed hair and the ...very top of her cleft; all it would take is for her to part her thighs fractionally and I would have an unobstructed view of her pussy.Her fingernails still remained on the flesh of her thigh and although they didn’t move they did appear to press a little into her flesh as she sat there. The finger on her other hand once again was tapping the side. She did not know how long she had supposed to spank for but as the intention was sexual arousal she could see that Sheila was well in to that stage.CRACK! CRACK! CRACK! CRACK! CRACK! CRACK!She stopped at that point and looked at the red pattern she had painted on Sheila's backside as her friend got off her lap.Sheila rubbed her buttocks with a pained expression. "Fucking hell Yvonne, you certainly stung my arse."Sheila then realised that for her to now spank Yvonne she would have to put her. Mom got up, and said, "Go shower, I will make my big boy some breakfast." "You really are the best mother in the world," I complimented. Walking to me and firmly grabbing my semi-erect cock, "And don't you forget it." She gave one last tug and disappeared. .....I put on hold my attempt to find out more about Ellie’s past relationship with my mother, as I focused on Miranda and the upcoming wedding, which had become a full-time job. Miranda paraded me around at work, flaunting me in front of her. It had been awhile since either of them had been with a woman for sex. They were feeling relaxed and talked more freely about their past lives and present their situation and Sam let it slip that he was bisexual. Sam was not sure what Bill would think. The talk of sex was arousing both Sam and Bill, and it was showing.Bill said, “I use to have a friend in college that I had sex with a few times.” Sam felt relaxed that Bill did not panic. Sam asked, “Have you had sex with guys since college?”.
