Breathing hard, on the brink of surrender, I peered up at Laura, gazing over her toes. Her face was a mask of utter desire, eyes squeezed shut, lips h...nging open, chest and neck flush crimson as she fought her own internal struggle.All of a sudden, I felt her toes curl against my face, I felt a long shudder ripple down the length of her leg. Her spine arched up, her head pushed back, she opened her mouth in a silent, prolonged scream of satisfaction.Then my own orgasm took me, sweeping me away. You are being used as a sex toy by a brother and sister. Nathan is thrusting his dick into you harder and faster, you can feel his dick thrusting into your womb. Your moaning heavily into my pussy and im grinding my clit onto your chin. As Im squeezing your tits I can feel my orgasm building as your tongue darts in and out between groans. I strat to grind my clit harder on your chin as my orgasm builds. I moaning myself into the air. "Oh fuck Sarah, I want to cum in your mouth", "Make me cum". Not since, in a moment of pubescent ire, I refused to answer to what I thought was a childish name. I wanted to be Tom, the grown up. My parents indulged me. From that time on, I was Tom. Calling me Tommy suggested, in some ways, she had regressed.“No, mom! You don’t have to suck it!”“I have wanted to for a long time, you know.”“Wait! What? I’m sorry, mom! What did you just say?” My head buzzed with my arousal.“After I saw you jacking off watching your father and I fuck, I developed this over. Each thrust felt amazing and better than the last. I slowed down to allow each of us to catch our breath, and then started pounding her pussy again without warning. I did that for a while and decide I wasn’t finished tasting her yet. Now she was soaked with her pussy juice. I flipped her over and lifted her legs again, not wasting any time getting my tongue on her clit. My fingers filled the hole my cock left a second ago. She cried out and her hand did not listen to her brain and involuntarily.
