I want every inch all night long. Make me cum." Then she grabbed his ass and spread his cheeks. He screamed, "finger my ass baby. finger fuck me hard ...as I fuck your cunt." she did just that. She started with one finger then got up to three in his ass before he shot his load deep in her hole.They both laid back and caught their breath. The sex had been erotic and mind blowing. He hoped she did not get pregnant for quite a while. He wanted to fuck this lady again and again. They then fell asleep. Damn this is getting hot. Oh Christ man this is your sister! Whatever I have to get through with this, I can have post-orgasm regret later, and let that fuel me to never do this again, but right now, let's just get this over with. I looked down at her perfect midriff, slender and smooth. Her belly button looked adorable and I probably couldn't fit my pinky in there. She was a little on the skinny side, but that's natural at this age, with the sudden growth spurt and all. Speaking of which I was. After 2-3 chats, I brought the topic of bdsm and how I wanted to experience that. Thanks to 50 shades of grey, she agreed to it. I have never read 50 shades of grey but was into bdsm when I was 17-18, just never got a chance to try it. She was into soft bdsm and after a little persuasion she agreed with two rules – no oral and no anal.The d-day came and she came to my room in the evening, I was waiting for her wearing jeans, t shirt and shoes. She came in t-shirt, jeans and sandles. I closed. He pulled her into the house and kissed her passionetly before smiling down at her. "Ready?" His voice was surprisingly gentle."Ready." she confirmedHe had her on her hands and knees, the skirt riding to show everything and walked her into the living room where two other men sat sitting and talking. Both the men were handsome, but not as much as her Master. The men looked up when she entered and smiled at her. "Turn around slave, let me see that ass" The man who spoke had a harsh, deep voice.
