I pushed them to her ankles without even looking away from her pussy. Those two silver posts were nice to look at. I helped her step out of her pants ...nd then I asked her to sit and spread.She laughed and said, “I paid for a glass of wine and I want my glass of wine. If you want me to sit and spread it’ll cost you another glass.”I got up and brought her two glasses of wine. In fact I brought in bigger glasses than the one that I took out. In essence she got three or four times her original. Kissing down my stomach my abs tighten and then down to my hip and over my thong. My hands are free now and I grab your hand thats on my breast and wrap my legs around your shoulder and one across the back of your neck getting you in a triangle submission....O LITTLE GIRL I STILL HAVE ONE HAND FREE>>. So with your head between my thighs I squeeze and you reach up with your free hand.. grabbing my thong and pulling it to the side your tonuge touches my clit and you begin to lick my pussy.. 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. She was still naked. She was sore in places. She was alone. Going around her place nothing was wrong, the door was lock. She looked at herself in the mirror and found only a red spot on her neck. Nothing else. She couldn’t find the clothes she had on Friday. Her phone had three missed calls and said it was Monday morning. Was it was a dream? Was it real? It had to be real. She felt it in her bones that it was real. It took days to get her head straight. She looked at everything differently..
