She’s very pretty. Very sexy. You know… her body changing with the baby.”I was surprised at Ron commenting like this about my wife, particularly...since he and I had just met… yet I was suddenly feeling a bit strange. Like I was having trouble maintaining focus and my words seemed difficult to form. “Hey” asked Ron “You okay?””I don’t…..” my response trailed off.“How many drinks did you have?” asked Ron.“just two buuuu….” I seemed unable to form a sentence.“Let me help get you back to your room”. She shot up like if someone had jabbed her with a cattle prod or hot iron. That also brought her back to reality and she said with a smile that we should get going before someone sees us. Little did I know that someone already has and watched everything we did? So I helped her down and we got into the car I started it up and off we went. She was looking for her clothes but she couldn’t find everything like her bra or panties I guess they fell out when I helped her out of the car. It was no big. It was the only time I've ever had an erection in a nudist situation. But this didn't bother Cathy at all. She just smiled and hid my embarrassing situation inside her pussy. Now if you think an erection is uncommon on a family type nudist beach you're right. But what Cathy was doing was even less acceptable. She managed to fuck herself on my pole so smoothly that the people around might have even believed she was only sitting on my lap. They couldn't be sure I didn't have my penis inside her,. I copied her and she applied the lipstick generously. I was delighted, it would match my shoes. With that she turned me around and walked me up to a full length mirror.I looked into the mirror and saw this pretty slim woman looking back at me. I caught my breath and a small tear escaped my eye. There was no doubt that Daddy would love this.We then walked over to the shop assistant and mistress instructed her "darling please gather up the usual slut wear for my little sissy. You know for when.
