She screamed in pain. She was saying ‘ no, no,no. But he didn’t seemed to listen her. To control her screaming, he inserted his underwear in her m...outh, and with full force he again pushed his cock inside her thus breaking her seal that too in front of me, she was not a virgin now.She tried to scream but not able to do so. He was fucking her continuously now after few strokes she was now moaning. It seemed she was also enjoying this. There were 4 legs on my lap. 2 sexy legs of my sister, her. No. It was the pain that I was going to inflict on her husband having to watch us that actually gave me an overriding sensation of deep satisfaction. And in a way I suppose it's in my nature. Not to detract from the events but at work I've been told that I'm too dominant as a person and that my team working skills are hampered by the fact that I pick on weak people. This is clearly just my nature, and I guess I'm just so cocky I won't change it. When I arrived to the house I was greeted by her. "Nick! I was afraid you wouldn't come."I tried to smile, "Would I ignore my best girlfriend? No way. I came as soon as I got the letter." I am so glad you did. I have missed you so much." She hugged tighter. "How are you anyway?" Not bad. How are you doing? You said you needed my help..."She frowned, "I don't want to get into that just yet, I want to visit." She took my arm. "You can stay for a bit can't you?"I tried to say no but I just couldn't. The look on her face was like a lost puppy dog.. "Daddy?" came a voice. It was my daughter, come home early. "You home?" "Yes, baby," I called. "How did it go?" "It was ok," she replied. She shrugged off her gym bag and her jacket. "It got boring, so I came home." She plopped down beside me. "What are you watching?" "Oh, nothing," I lied. "I'm just flipping through channels." "Thinking about going camping, daddy?" she giggled. "Nice tent you've erected." I looked down, noticed my erection. I started turning red. "It's ok, daddy. I'd go.
