It seems like everybody knows it. But I didn't. Not until that night, anyway.I learned something else too.Always have a pillow handy if my sister is g...ing to have an orgasm.This started a new phase in our lives as siblings. Addie loved sucking cock, at least my cock. And she really loved it when I went down on her.That first time, on my bed (and yes I know it was technically the second time, but the first really didn't count in my book) she was very vocal. By that I don't mean the screaming.. I accidentally started to gain massive speed down as my legs were locked trying to hold my bladder. My body ache and I hunched forward trying to minimize the pain of the ocean inside me. I managed to get down safely without falling over and totally soaking myself.I ran towards the bathroom, only to be discouraged by the extremely long line as people started to leave. We decided to return boards and skis, I was totally crunching over with my legs squeezed tightly trying not to pee as I was. "I'm one lucky bastard. Lucky that my accountant was fucking my wife. Lucky that I came home early and caught them. Lucky that one of them shot me in the head. Things are just going my way, Doc. Let's get this done while I'm on a roll!"It turned out that my head wound never bothered me very much. That's because within a couple days, I was split open like a fucking clam, for a quadruple bypass operation.Janet had tried to see me before the operation, and again when I was recovering. I refused to. He checked the durability of the bed, sat on it and felt its weight and nodded affirmatively at this. He unzipped his knapsack, took out the clothes he'd arrived with and hung them in the closet. Finished, he took off his clothes and stood in the room naked. Caya felt herself become wet as she appraised his magnificent body, the beauty of his abdomen and his cock which hung between his crotch. Standing this close to him, his masculinity filled the room. She wanted to stimulate her pussy but was.
