I told him I didn't think I could do it. He smiled and said that it was done, the head of his cock was in me and the painful part was over.He lifted m... head up so I could see and sure enough his cock head was gone. The only thing I saw was his thick black shaft outlined against my lily-white ass. He let my head back down and slowly began to move his cock in and out of me, each thrust going a little deeper. It was painful but with each thrust the pain became less and a strange, pleasurable. Saturday evening came round and our parents went out, I arrived home around 8 o'clock and my sister and Christine were sat in the back garden as it was still red hot, I joined them and sat in one of the sun loungers, I took off my tee-shirt and sat in my shorts, after a while Christine said its not fair you can sit without your shirt on and we have to sit fully dressed and sweating, I said you can take your tops off nobody can see you only me, my sister said no way, after a while and a lot of. . Her soul mate.. Have just had dirty sex behind her back If she ever found out then that would be the end us and she would prob never want to speak to her mother ever again... I tried to block out the guilt and I looked up at Sarah and her eyes had now gone from horny to upset.. As my mother inlaw began to climb off of me releasing my dripping cock from her pussy she looked at me and said I'm so sorry Matt this should of never happened I don't no what came over me she said as eyes were. ..so good...daddy." She kept her hands pushing him in her mouth hard. "Mm...mm...mm...it's hitting...the back...of my throat...daddy."She pushed his cock out of her mouth but kept her hand playing, "I going to cum daddy. Your finger in my pussy feels so good." She was moving all over the vanity, "Make your little girl cum daddy!" His fingers were playing and sliding in and out of her making the pleasure better and better. Waves of pleasure burst through her. After all of these years, her dLaddy.
