Hers hung down like two loose flaps of skin. They actually wiggled from side to side as she stepped sideways with one foot. Then she lay down on the b...anket and I couldn’t see them any more because her knee was in the way as she pulled them up and reached between her legs. I imagined her fluttering her fingers over those lips. My dad sank down on his hands and knees and he stuck his head between her legs. I heard smacking and sucking noises and she rolled her head back and forth. Her hair was. My fingers tantalizingly close to her tight ass. So close.She darted into my room and I followed quickly, close on her rear. But not too quickly to flick a switch as I entered the room, turning on the lights. She stopped suddenly and once again I bumped into her. Only this time I did not stop. I ran into her, grabbed her by the hips and threw her onto the bed face first. I intentionally fell onto her back and sank my face into her neck. My tempered steel cock was buried in her crack and I. “Oh no, not yet,” I thought, but it was too late. I shot my sperm out into her vagina, a mere three inches into her. I hadn’t even attempted a full penetration. I HADN’T EVEN FUCKED HER YET AND NOW I’VE SHOT MY WAD! OH MY GOD, WHAT HAVE I DONE?I pulled out quickly and rolled out from between her legs. The look on her face made my heart sink; it was one of sheer pain, disgust and disbelief. Suddenly it dawned on me I had just raped my sister. She got up without saying a word and walked to. She stopped him.“Nothing for me son, I don’t feel like eating this morning, just the coffee’s fine.”Then it struck him, today was June 5th, the seventh anniversary of Pop’s death. She’d be blue all day.After breakfast she was a bit despondent, she wanted to do something to keep busy. She’d hung her gown on the line as she did every morning, this morning she decided to air out her sleeping bag. She brought it out, unzipped it and hung it to be freshened.Later they took a walk, they talked.
