She tried to cover her face with her hand, but I had already seen the wanton lust on it, as the dog continued to fuck her."I tried to stop him…," sh... lamely started to say but the huge moan of pleasure that escaped her lips overshadowed anything she might be trying to tell me. She started pushing back against him matching his ramming thrusts into her pussy, completely giving herself to the lust of the dog doing her.I laughed loudly as I pulled my sister's phone from my pocket and started taking. .She was wearing light pink saree…Semi sleeve blouse and back deep…She has tucked her saree below her navel..She was looking so sexy…She went to bring juice for me into kitchen..I followed her and hugged her..She was in shock again and said…Not so early darling…We have lot of time.I gave a light kiss on her neck and shoulder..She turned towards me and gave kiss on my forehead…She gave me juice which I made her also to drink..We both shared..Then she took me to their bed room and asked me to get. “Take that dick,” Sandy moans. “You know you love dog dick. And you,” she says, looking down at the man. “Make me cum for you.”Alan attacks her pussy with a vengeance. Sandy moans loudly as his mouth muscle swirls across her clit. Her hips rock into his face.“There you go, Bruno,” Sandy calls out. “Fuck her. Make her cum for us.”Bruno is panting heavily. It is clear the large dog is getting close. Alan cannot wait for it. Cathleen has wanted this for so long. Bruno will knot her, he would get. Then he sat in the passenger seat and masturbated like a pervert, his need too urgent to care that anyone could walk by and see him. He came in less than a minute, all the time thinking about his sisters body, thinking about those lips wrapped around his cock. He cleaned up and drove back to work. He went about his work as normally as possible, but found himself staring off into space, his mind going back to his sister. He went out for drinks with a buddy so that he didnt have to go home so.
