I was a new guy and gradually made friendship with my classmates. Amongst them were a few girls out of which I was attracted to 1 girl particularly. H...r name was Sanyukta. She was a sex bomb of our college. But I being very open -minded enjoyed a good friendship with her. Soon we became very good friends. We used to bunk the lectures and go to movies and Beaches, etc. We were just enjoying good friendship.One day our group decided to go to a Waterpark in our city. We all agreed and went there. I suggested he might like to see her in some of her jewellery he had given Anne, and he jumped at the chance. So Annie went upstairs to put on a small items for Mike. We continue drinking and every time she went away to change the jewellery, she would change her outfit, and each time it was getting more and more revealing. Finally she came down she was wearing a pink silk bra, pink hot pants, that showed he camel toe, knee length boots and his wife’s necklace which disappeared between her. She only smiled at my quizzical look. Then walked toward the closet and slipped off her work clothes, bra and panties and shimmied on a pair of tight short shorts and a very form-fitting tank top. She looked absolutely slutty and stunning all at once. I slipped off my clothes. She chuckled at my growing cock. Walking over she gave my penis a little tug and coyly said, "you better save some of that for later. I hope you're up for it." Laughing, she laid me on the bed and fastened the cuffs to. She loved to be tied spread eagle (not painfully) and blindfolded and have me arouse her and keep her aroused. So I dreamed up a way for her to be tied but for her to still be in control of how long I gave her oral sex. We already had bondage ropes that I usually used on her wrists and ankles that I had made from some old leather belts (shortened with extra holes drilled in them) that were tied to fairly strong nylon clothes line. But I made an extra leather collar that would lock around her.
