Actually we wore matching outfits except for the color; Cathy dressed me in red while she wore white. Those dresses weren't much even by mini dress st...ndard. They were halter-top affairs with peek a-boo fronts that would have shown the waistband of our panties if we were wearing any and the backs left us naked right down to the top of our ass cheeks. I was expecting a woman doctor, not the distinguished looking older man that ushered me into his office. As we talked he started undressing me. I didn’t mind though I kinda liked the taste. Once in my mouth it wasn't long before Bruce was hard again. Then laughing, Barbara told me, “Now you’re going to get fucked by a real cock.”She told me I was getting looser after all of her fucking and then she pulled me off of Bruce's cock and bent me face first over the edge of the bank. When Bruce moved back in the water, Barbara wrapped her fingers around his thick cock and stroke it a few times before she guided his big hard dick into my well. The hot stone was brought in and the opening covered in pitch black. Could not see a thing but I immediately felt a hand come from my right side, Ruth, groping my thigh and eventually finding my half erect cock. But as before as the temperature rose and the water thrown on the hot stone rapidly increased the apparent temperature the harder it became to sustain even a half erection. But she massaged it and my balls as the sweat stated pouring off me making them slippery my cock was soon rock. "I'm going to give this little queer my ownership mark" he said, to great rousing cheers from everyone, with this he gave me the hardest spank I have ever received (even to this day!) and left a perfect handprint on me. "Anyone can use my sub, just ask me first as I own it" The whole time, his voice was at a conversational level, not shouting or aggressive in any way. I nervously looked around, and Derek slapped my face, telling me only to look at the floor unless he said any different. One guy.
