It was an orgasm of sorts, but unlike any previous, as if my body, my extremities, had become liquid pouring from my cock. Unlike the lightning strike... fireworks orgasms of the past, this one dragged on and on. Consciousness left me, flowed from me with the fluid from my cock. I collapsed onto him like the skin of a deflated balloon, but still he went on and on. My cock stayed hard, its naked head flopping up and down on the cold slimy porcelain as he forced his fearsome rod up, up, up into me.. I finish off and race into the shower. Drying off in the cubicle, I hear giggling coming from the shower area. I knew Emma was around but hadn't seen anyone else. I peeked around the door and saw Emma naked in the shower. Nothing unusual as she often showers before being picked up for home. Then into view came Clare. She walked to Emma and stood still. Emma reached out and stroked her face, as she leant in and kissed her fully on the lips. Clare responded and they stood close together, under. My wife came up to me, “Everything okay sweeties?” She asked putting her hand on my arm. I turned and smiled and raised my hands, shaking, “Too much estrogen!” She laughed and gave me a peck on the cheek. The last time I felt her touch before I cheated on her. I told my wife I would clean up the kitchen and dining room and they could all go back to enjoying the pool. Soon the house was quiet again and put away all the condiments and leftovers, wiping down the table and chairs and swept. The four girls decided to hike to a nearby lake, and by the time they got there it was warm enough to think about going for a swim. Without bathing suits, skinny-dipping was the natural option, and even Sally hesitated only briefly before peeling off her clothes and diving in.The water was cold but after a while they got used to it, and all four had a good long swim. J.J., the strongest swimmer in the group, pointed to a bank maybe 100 yards away and challenged everyone to a race. Only Sally.
