I went for three more rounds the same night as I was very horny for my mother.After the fourth round, I was very tired and fell asleep hugging my moth...r with my dick still inside her. In the morning when I woke up, I realized what I had just done the previous night.I looked for my mother but she was nowhere to be seen. I got scared and searched for my trousers but it was missing from the place where I had put it the last day. But it was nowhere to be found.I was sitting on the bed wondering. So we hatched a plan to do so, the next day she made plans with him to go away for the weekend at a nearby vacation spot. One the weekend came, she phoned him and told him that she had to work late so he should go ahead get settled in and she would meet him there later. Once we were sure he was settled in and had a few drinks, she phoned him again and told him that an issue at work had come up and she " Regretfully could not get away". She convinced him he should stay since the he was there. Malcolm brushed my oak-colored hair off of my face with both hands. I grimaced as his skin passed over the fresh bruise on my cheeck. He didnt seem to notice. Get down on your knees, he ordered. Once I was on the ground, he spoke again, in that deep voice of his that made me undeniable hot and sent a chill down my spine. Get my dick out. I fumbled for a moment on the button of his jeans, causing him to impatiently reach down and do it himself. I managed to get them down to his ankles. It seemed. And when I reached the back of her knee my cock had hardened as much as it could without bursting. The skin under her knee was so smooth and warm that I just had to feel how it felt on the upper side.When I cupped the knee in my hand and my thumb by accident stroked the inside and a little up on her thigh my sister shivered a little and I looked up at her face expecting her to look at me but she had her eyes on the book. I noticed that her eyes didn't move, they just stared on the pages before.
