I eased forward and then back, forward and back, accustomizing myself to the girth, or trying to. It was a lot to be accustomed to. I breathed through...my mouth, found myself staring blankly at the jamb ahead, alternately approaching and retreating from my face.I had never cheated on Ken. I didn't consider what I did to myself in his absence as cheating. It was simply pleasuring myself, as I'd done all my life. I knew he masturbated in private--all guys do--so he must suspect I did the same.. She laughed again and said he is someone with a big fucking black dick unlike you and I am fucking him to stay satisfied and if you know what is good for your little cock sissy ass you will lick my pussy clean. I stood there for a second thinking how and what but in my mind I already knew I couldn't satisfy her with my cock and knew she had been fucking around with my friends for over a year. I must have been looking off into space when wendy said lick my pussy you fucking faggot. Without. I don’t actively go after girls that are taken,’ I explained my actions. ‘This time I had to pay the piper.’ ‘You came after me,’ she taunted me with an innocent smile. ‘I explained that, you were getting your own drink so I didn’t think you were on a date. Ergo, you were fair game.’ I laughed at her reaction to the fair game comment. ‘I mean that I thought that it was okay to say hello to you.’ Shannon accepted my explanation and we continue our lunch and getting to know each other. I kept her. She glanced down and gasped at the sight of my dick. My little sister shuddered, her small breasts jiggling in her belly shirt. She drew in a deep breath and said, “Do you need me to... ?”I nodded. “You’d be a great, little sister if you did.”“Of course!” she gasped. “I’m your little sister.”I groaned at the incestuous contact of her hand grabbing my hard dick. I reclined back in my seat, not caring that people were coming in and out of the store. They walked by the car as my little sister.
