My calculations show I was ovulating today. Just an hour earlier, I had felt the sharp little tug that told me my left ovary had expelled an egg.Some ...eople think I’m nuts, but my Gynecologist told me that about twenty percent of women can feel the moment of mittelschmerz. That’s the exact moment of ovulation when the egg actually breaks through the ovary’s wall. I’ve felt them ever since I hit menarche. I had an egg on the way through my left Fallopian tube, heading for my womb. That egg was. He watched her eat while he enjoyed his own meal. "You've been very good lately, Baby Girl." He smiled down at her. She looked up at him, and beamed with pride. As they finished their meal he paid the bill, tipping the young waitress who'd been doting upon him generously. He led her back to the car and she seated herself. She thought they were heading home and planned on quietly napping on the way back. "Stay awake, Baby," he said, softly. She looked up curiously and watched the scenery go by,. Heather reached between us and groped for my prick which had reached maximum capacity. She wrapped her fingers around it then lifted her legs around my waist. She shifted her hips until she could guide the end of my cock into her body. I pushed into my sister, she adjusted on my cock then we started fucking in the Gulf of Tonkin.Steve and Margo were staring at us as we coupled. Heather turned her head toward her twin and nodded to Steve. Margo smiled, grabbed Steve’s hand and led him out. The details of their coupling aren't especially important; that it happened at all was. And imagine this: the guy emailed me a confession of what happened, saying that he was feeling so guilty about what he and Laurie did. Bullshit was my personal response — I know that he had always had his eye on Laurie, he took advantage of the situation, and he wanted me to know.The result, as one might imagine, was that by the time Laurie arrived home, I was loaded for bear. I was ready to kick her.
