After those 2 days, my brother-in-law went back to his house. Because of pregnancy, my sister used to wear loose t-shirts, nighties, dresses, and sari... At home in general, she used to wear a t-shirt with pants, sarees, and nightwear.A few months continued like this. I was going to my office regularly for meals while she would share all the love stories of her neighbor and the fighting of husband and wife in and around neighbors.We were like friends more than siblings and I would share all my. I explained that we are not swingers. Krista said it turns her on to see her husband enjoying other women. I said, We've never done anything like that and I thought that was the end of it. A while later, her husband Mark came out in boxers and a t-shirt. Krista encouraged him to take his short off and come in. Mark asked why he was the only one that had to take his top off. Krista said, we'll join you and took her top off too. I was there in the hot tub with the two of them and Krista's big. Suddenly she dug her face into his as cheeks and sucked on his ass hole. "Mmm tha's nice, stay like that for a while..." Mr. Taylor said. After over a half an hour of sucking on his ass hole Mr. Taylor grew bored. "Kay, I'm done. No need to do the rest of the body." He said standing up. "just get your ass back down on this table." he said throwing her on the cold metal. "That was the punishment you chose. Now it's my turn to choose yours." He finished, re-tightening the restraints on her legs. The girl showed me her cabinet and we entered together.I was little bit nervous and excited.When we came in i said: Sarah, how are you? Nice to see you at last...LOL girl closed the door and we were alone at last. She was So surprised. said i m so crazy.lol. but there we obviously that she was more then happy.We talked a while she was laughing, We exchanged some very serious "deep looks"eye in eye.Suddenly she said i had to go because people will come in her office.I hold her hand by the door.
