Our story begins in that time of year we all love - summer & a balmy night. We look for couples whose profile shows a considerable lack of inhibition & plenty of imagination. We found such a couple willing & ready to join us for a late night skinny dip and aquatic swap.
Having been asked what they should wear for the evening it came as a pleasant surprise when they agreed that little was needed & the few clothes they had would quickly be discarded.
Settling in by the pool with a socialable wine, the toys which were to be used & towels a good distance away we were all quickly naked. The boys were the 1st to enter the pool however us girls wanted the time to admire each other more closely so we kept our seats.
Discussion between us girls quickly turned to our experiences with female to female encounters and learning from our visitors that although she had limited experience the thought of me being dominant wetted their appetite. Her husband had hoped that I would DOM his wife for the evening for his viewing pleasure. From prior experiences my partner would have no issue's with this either.
Standing I grabbed her & lead her naked into the pool. As we were still all chatting I ordered her to squat on my thigh so she became comfortable in me controlling & feeling her pussy. When I believed that the social chat had run its course my partner retrieved my thigh strap-on dildo for my use.
Facing me she mounted the strap-on without hesitation & I controlled her thrusting from gentle to forceful and hard.
Thus began a four hour private pool party.
