"Have you ever been with a girl?"I was so surprised by this side of my sister, but honestly part of me felt sorry for her because she was obviously so...undersexed. I really wanted to make her feel good, even if it meant crossing some barriers that even I had never crossed."Maybe," I said, smiling."You sneak!" she said. "I bet you've done all sorts of things I've never done." It sounds like you've done everything with Daddy that I did."I moved forward and propped myself up on my elbows between. ” Stacie robotically responded.She was faking for him. Derrick was a good guy, she definitely didn’t want to hurt his feelings, but she didn’t have an emotional connection to him. He was just sweet, funny, and wasn’t her brother, apparently. As I moved closer to her door, I noticed it wasn’t shut all the way. It was cracked just slightly that I could get a view of my sister on her back, legs spread while a chubby guy pounded his surprisingly thick 6-inch cock into my sister’s dripping. " Why in hell is she yelling?"This whole last part of the conversation was done over the protestations of Mallory who didn't think that Ken was feeding her fast enough. He was trying to feed her with his damaged left arm while holding the phone with his right. He had some movement of his arm by now, but he couldn't get it up to his ear yet."Your phone call interrupted me feeding her mom." Well fuckin' a get back to it!" Yes mom."Ken quickly finished feeding the boisterous child and hurried over. “Yes,” I whispered, and he did continue. He jerked me slowly at first and then he ran his hands around my balls and up across my pubic area. “You don’t have much hair,” he whispered as he went back to jerking my cock. I didn’t then and don’t now have a big cock. But I get hard and my mushroom tip is much bigger than my shaft and I felt his finger rubbing over the rip of my tip and shuddered.“Tell me when you are going to cum, I will catch it,” he whispered and that is all it took, I moan softly.
