Every time I turned around, it seemed, Ma or one of my wives was talking to Mary. I couldn't miss seeing the shocked look on Mary's face during the ea...ly part of the day, but that changed to one of consuming interest by noon, and she looked downright smug by supper time.That evening, I sat as usual in the swing on the front veranda, but I was surprised when I was joined immediately by Mary. The other women were cleaning up after supper, and Mary usually helped with that, but even I realized. I moved my mouth to Jay’s balls and proceeded to suck each one before returning to his rod. Jay had the foreskin pulled back, and took the head of my dick in his mouth. That did it. I fountained semen into his mouth and he drank it down. Less than a minute later Jay let loose with a fountain of his own. Hungrily I sucked down his cum, and then we broke. The girls had stopped working on each other to watch us. They traded mutual masturbation for the cunnilingus. Neither girl had an orgasm, but. Spring really is a time for rebirth.The passing runner looked up. Even though her brown hair was pulled back and tied tightly in a ball, I could see that it was Dawn Zimmerman, the young woman who I had let retake an exam the day before. She waved and I nodded and half-waved in return. She kept running and I kept watching, the words of my graduate assistant still ringing in my mind from the day before. Where I hadn't been thinking of Dawn in a sexual way, the sex from the night before was still. Slim, dark haired with the face of a model and a killer smile. If Jo ever found out about how I thought about her I'd die. I must be the only brother on planet earth that dreamed about his sister, and I never shared that fact. I had seen Jo topless last year when she forgot to close the bathroom door all the way and I had walked by and seen heaven. She was combing her hair nude and I saw her tits and her legs and beaver.I was thinking what a mircle it would be if she posed nude when Jo walked.
