I threw my head back, holding back, just holding back. She lowered all the way, until I was fully sheathed inside of her. I moaned, long and low."Don'... come yet," she said, and she slowly started riding me. I squeezed my eyes closed, and hung my head backwards off of the couch. It felt so good, her fucking me. I wanted to just let go, but she wanted me to hold back. Her ass felt even warmer then her pussy did, but it was so much tighter. I could smell her ass so much more strongly now. It was. She was looking on to my penis.I asked her sleep so I can apply oil on back. I poured oil on her back. And started slowly massage from top to bottom back. She was enjoying.She told I am doing good massage. She said she had done in parlor but that was hopeless and useless service.I said thanks. I slowly started applying more pressure on back during pressure. She was started moaning.After 15 minute back massage I sat on her soft and sexy ass and applied little bit more pressure as per her comfort. This time it was much better and on further tries she was almost ok and without my help she it again and again. After that, we played throwing water on each other and pulling and pushing.All the three were after one or the other to dunk each other. In the process all of touched each other even on forbidden places I even managed to squeeze Shweta s balls, for which she smiled. By now, it was too late and all of us were tired and hungry by swimming continuously for hours. I suggested stopping. I tied the rope around her neck and then tied it to the top bolt. All the while she did not struggle.I walked back behind her and continued my rubbing of her ass again but this time having everything exposed to me from her bent over and the lack of rope allowed me to slip my thumb in her ass a few times. Each time I did she only clinched a few times before relaxing. It seems she might have done this a few times.Stopping for a moment I walked over and grabbed the bottle of oil and drizzled some.
