I knocked to announce my arrival and went into the room, my nose sniffing the air, like an a****l, my senses were alive, I was trying to decipher what... might have transpired in my absence. My sister was on the bed, relaxed and happy looking, 'Where were you', she asked innocently, once I had closed the door and sat down beside her?My boyfriend was still on the floor, looking up at her and I wondered if he could see her knickers the way she sat in front of him.There was something quite different. "I'm good, Mom. I'm really good."She smiled back at me, then turned her attention back to the road. I few minutes later, she spoke again. "They're pretty girls, aren't they?" Yeah, they are." I looked at her out of the corner of my eye, but she still had her eyes on the road. The way she said that made me think she suspected something. Her next words confirmed it."I can tell you have a ... unique ... relationship with them. Whatever happens in your future, you make sure to treat them both. Fetterman?" came a modulated voice on the phone."Yes?" This is Detective Simpson. I'm calling to give you an update on your case." Case?" The sexual assault investigation," he said, being politically correct."Oh." The box opened, but the memory was still a hazy, dark ball. "I don't remember much about it," she said."We have everything we need," said Simpson. "I just wanted to let you know that we believe the man who did it is now dead." Dead?" Yes, he was killed in an accident. He won't be able. To get a better rhythm my hands went below her and grabbed her ass cheeks, her nails were digging into my ass in her climatic throws. I slipped one finger towards her ass hole and our eyes met and she said, “Yes!” as I started to push my finger in.Her juices were flooding down over her ass and I used that lube to allow my finger to begin fucking her.My balls began to tighten and her ass was spasming around my finger as my big dick began unloading into her cunt. “Fill me John!” she.
