Not knowing what to do, she stifled back the tears and headed up the stairs to get ready for bed.The water from the pulsating showerhead sent shutters...through her body as the water pounded down on her breasts. She raised one hand and messaged each breast back and forth up to her neck then down to her erect nipples.As her excitement grew she lowered the other hand between her legs and gently stroked her clit, producing a soft moan. The water from the shower made it easy to glide her fingers. I went in secured a room we went upstairs and the fun began. Harry went in the bathroom and I immediately started kissing Sandy and helping her out of that sexy little dress. When the dress slipped off her shoulders and fell to the floor it revealed her stunning figure and the lacy black bra with matching panties and the black garter that secured the nylons that clung to her perfectly shaped legs. Her figure was intense, that beautifully shaped ass that had just the right bubble, her perfect. We passed a couple of other guests in the hallway and the look on their faces was priceless when they saw how we were dressed and what we were carrying in our hands. My towel had a rather prominent lump in the front. I wonder why?She wanted to shampoo the chlorine from her hair and I offered to help her. We dropped our towels on the bathroom floor and got in the large shower (with the dual, high mounted shower heads) and rinsed / washed the chlorine off. I then took a big dollop of the new. Billy was only sixteen months younger than his sister and I thought he might rebel at her leadership, but I was wrong. He wasn't exactly enthusiastic about her giving him instructions, but he went along with them anyway.Sandy was still quiet, but had adjusted better than I expected. I got the impression she was happy to have Debbie take charge. She was also responsive to Christie as well. They seemed to get along very well. Billy didn't have any problem with Christie either, so that took a big.
