"I can't wait for morning," She whispered as she snuggled back against me and we drifted off to sleep.Morning arrived a little ahead of schedule, I aw...ke to sensations of warmth in my groin and I looked down to see Kristen carefully washing me with a warm washcloth, and then drying me with a soft towel.She smiled up at me in the still dark night, illuminated by candles and bent to take me in her mouth again.There was no urgency now, as there had been before. She curled up next to me and gently. The whip was rolling off of my shoulder and she was lazily swinging it back around and up a gain… and again … and again. It was wrong. It was disgusting. My cock got harder and harder. I lost count of the number of lashes. I watched her cup and squeeze her breast. She pulled the stretchy material above each. Then she lifted one to her mouth as she continued to stripe my flesh. It was pungent, salty… It was her and I suck and licked her like a mad man. When I moved my mouth up after. The stranger’s hands pawed at her hips and then moved to her shoulders. He then moved his hands to the front. The rough hands squeezed her breasts and tortured her nipples. Muscles on his thighs flexed when he pressed in and relaxed when he pulled out. The cock was large enough that Stephanie bit down and cried in pain with every movement.Stephanie took a moment and watched her little sister’s torment. She wished she could do something to help. She looked over her right shoulder and gazed at. She mentioned they wanted to experiment a threesome in real life and hence they had messaged a few guys like me and are choosing the appropriate guy to do it with. I was very patient and heard her and then told her I am willing to cooperate if they are.She mentioned they lived in Mumbai in a very posh locality of lokhandwala and they could not travel. I told her that whenever I plan on visiting Mumbai I shall inform her in advance.Whatsapp chats became a regular thing and slowly we started.
