He backed her inside still kissing her passionately. She yielded to his every move; there was no thought of resistance now. She knew where this was he...ding. Her head was now screaming at her to resist but her sweet virgin pussy was in no mood to take advice. The logic of her brain was cast aside by her virgin pussy howling for its first feel of a rampant penis. Her destiny was upon her, her fate now inevitable. Susannah was eased onto the bed. She urgently hitched up her skirt above her waist. Paddling slowly, she side stroked to one of the outer columns of their room. She turned her head as Jon splashed into the water just behind her. Rather than use the ladder, he had stripped and jumped down from the top.It was deep enough that he bent his knees and hit the sandy bottom harmlessly; probably a 10'-0" drop from the surface.He used the breast stroke to paddle over to his wife. With her hands on the column, steadying her, Jon came up behind and wrapped his arms around her. They bobbed. Her orgasm was quick in coming and very intense as she tried to stifle her moans. Her legs were shaking as she came. With her last gasp, her legs collapsed onto the bed and after a few minutes her breathing had slowed.As I knew he had passed out after her wild fucking session; I moved over her nice body. My hand found her wet dirty cum stained thong on the floor. The crotch area was soaking wet with Bob`s semen.Then I rubbed my cock head on that tiny piece of cloth and soon I felt my own. That is my way! That is how I do things, so that is how you will do things too."Jontar started to laugh until I fixed my steely gaze and gravelly baritone on him. "And you! You are not to make fun of your sister." But she..." Silence!" I yelled, before slightly softening to ask, "What is going on between you two?"They almost spoke the same exact words simultaneously. They thought I was going to force them to mate each other when they came of age.I wanted to laugh, but instead, continued to play.
