Hormones raged, body hair began growing and most of all I had this appendage between my legs that demanded attention constantly.But it wasn't until qu...te a bit later that the realization occurred to me that I was living with a beautiful female, albeit my sister.It started one day when we were each changing to go swimming. I was in my room across from hers and changed into my trunks in seconds. I was impatient to get across the street to our friend's pool and stood outside her door asking if she. He wasn't all that big but made me bleed because he was so rough. I was fuming and sought to get revenge. Since Mom and I were sort of in this together. I confided in her and she wanted to turn the tables also. The next weekend Babs was getting ready to go to a bar and told Mom and I to make sure we were good subjects and she may reward us when she got home. I stood up and told Babs that she needed to be good and that she wasn't going out tonight. She tried to blow me off. Until I grabbed ahold. I told Randy of my fantasy of Donna screwing other guys. He had a plan. The 4 of us would plan a trip to St Maarten. Randy has a house in a secluded area that he rents each year. Just before we go on the trip I would cancel out due to business, but I would encourage Donna to go and have a good time with Randy and Jane. Since we live in separate cities, Donna would travel alone. When she arrived there she would find out that Jane had to cancel at the last minute as well. Randy will be there with. Once there, we would proceed to undress each other and screw in every room, in every cubicle and on every desk we could find. At 5’7” 120lbs with C cups for breasts and long tanned legs to match her long kinky hair (in style at the time), I enjoyed every minute of those nights! That’s how I knew my wife had a naughty streak in her. She was a good girl too - so maybe it wasn't so much of a streak as it was a glimpse or a flash really . That naughtiness has long since subsided many years ago.
