I told them that she had done very little with girls but was sexually adventurous and liked to be dominated and even liked her sex a little rough. I w...as starting to feel a little aroused as the fact these two sexy girls were admiring my wife and excused myself saying I needed the bathroom too.When I got back from the bathroom Sarah told me she and the girls had been chatting and they thought it would be fun to take a couple of bottles of fizz back to our apartment and chill in the hot tub. We. You'll have to wait your turn."She then showed me her purchases from the lingerie store and the other places that she prefers to shop for "special" clothes. I made all the right appreciative noises and hoped that she hadn't noticed the reaction of my cock as the very thought of her wearing these provocative clothes and lingerie had got me instantly hard.The boys were out all day long doing whatever it is that Caribbean men do when they are on the loose but we had agreed that they would be back. .." I was moaning continuously at this point and I could tell she was enjoying it too. She fully laid on top of me without separating our pussies. Our boobs pushed together and she rested her head in my neck. Combined with the feeling of our clits clashing together and the warmth of her body, I felt my orgasm about to explode.

I took a large amount of the seeping ointment and applied it first to my ass hole then to my vagina; it was very thick and had little pink pebbles in it which tickled against my flesh.

She knew I liked to wear tight panties and intentionally buy ones of smaller size to feel them brushing.
