The affair lasted for a month before he was spotted with a short-skirted girl, coming out of a pub and jumping into a taxi. He was supposed to have be...n taking Sonia out for a meal that night, but didn’t call. Sonia found out about his alternative plans when Tracy, one of their few friends, gleefully told her what she had seen. Sonia was mortified and, inconsolably threw herself on the bed, promising to let her life’s blood. Michelle thought it a bit over dramatic, but made the right clucking. My sister saw Kim and without asking knew what had happened, "Hey Kim, got to know my brother?" What, my sister knows my girlfriend? Oh shit. "Oh yeah, great guy and life story. I think I got the 'thrust' of it." Said Kim as she gave me that coy look. She emphasized the word "thrust". My sister got curious, "So, how was it?" It was none of her business although I did want to brag about how great it was. "None ya'. Now let's go." I replied. My sister went on and on about how great the sex was. There was nobody at home as everybody had already left. She was wearing a spaghetti deep neck top which showed much of her cleavage. Down below, she was wearing a skimpy shorts which just about covered her cute ass and showed the curves of the bottom of her ass perfectly.She invited me in with a tight hug and her sexy melons were crushing against my chest. I got an instant boner which I tried to hide by bending my ass backwards. Also, while hugging her, I slowly let my hand roam on her sexy. Damn Woman your eyes She stopped me dead in mid sentence and said "Dude don't try to change the subject" besides she's my step Mom, not Biological. and "She probably just wants to get in your Pants", "Same as me" I was shocked to say the least Ah ? What ? what did you just say ? Dude I did not stutter she enunciated, as she grabbed my chin and held my face so I could read her lips Perfectly, Besides she already told me so."No way" ? "Yes Way !" she said. Why do you think it is that I am.
