Not long after that, I knew that you two were back to your old tricks. I did everything I could do to stop traveling, even though it was doing massive...damage to my reputation. But it didn’t matter. Given the smallest window of opportunity, she kept running back to you. At that point, I knew it was almost certainly too late, but eventually I gave her an ultimatum. Not about you — I still hadn’t told her I knew about you — but about the job offer. She coldly informed me that she needed some time. The taste of wine still on our lips only fuels the passion. Carelessly tearing the clothes from our bodies, and leaving a trail to the bedroom as we get ready for some hard core sex. No foreplay tonight. No, loving, and tenderness this evening. My cock is already hard before I bend you over the end of the bed. Your pussy not quite ready, but that doesn’t stop me. I can see that you’re a little excited, but not dripping wet just yet. I grab my shaft, and pull the head between your lips.. It's a problem befitting all siblings, when ones needs overtakes the others creature comforts.Not that her boyfriend minded, he knew I had seen them at it, giving her a good doggy as I watched them and he watched me.Her room door was open and she was loud enough to wake the dead. The bottom of the bed, which faced the door, was high enough to obscure her vision, as I stood quietly on the stairs, peering through the space left by the solid banister, all he saw was my eyes, but that was all he. My cock bounced in front of her, until she grasped it, steadying things so she could sink my hardness into her mouth, descending until her nose just touched my pubic bone. She drew off me, sucking all the way, and let out her breath with a “woof!”, that fluffed her bangs.I was goggle eyed. First, because this sort of suck-at-first-sight had never happened to me, ever. Secondly, because the deep throat she had just laid on me was pleasure like nothing I had ever had before. Third, because, she.
