I hated the admiring look Jon was giving her and hoped she would not be able to complete the exercise so I could spank her.

She did the first four pretty easily. Everyone applauded and yelled encouragement as they stared at her straining body and the way her breasts were slowly working out of her bathing suit top. By the fourth one her nipples popped out. They really applauded by the sixth when the top fell to her waist showing her really nice boobs. I thought she was going to make it although sweat began to run off her body and each one took a little longer to get her knees up to her waist. At seven she was panting and made several attempts but could not get her knees up all the way. She finally just hung there and moaned, "I can't do it."

Jon stepped up to snap some handcuffs onto her wrists and over the bar of the trapeze saying, "This is just in case you change your mind."

She looked dazed and didn't seem to notice her breasts were bare. Her husband stepped behind her and pulled the skinny triangle at the back of her suit into the crack of her ass causing her to gasp.

I stepped to her side and slapped her ass with the whip. She jumped making her tits bobble while they applauded and yelled "One!"

They became more excited at each count as the whip made a loud snap and red lines formed on her butt. I knew from experience the pain was not as bad as it looked and she confirmed it by just making small gasps and shuddering at each lash. I found that it really got to me. I had not expected it to be so exciting to be at this end of the whip and really had to concentrate on not hitting her too hard. By about the thirteenth lash some of the people had been engulfed by the excitement and had pulled off their suits to fuck dog fashion so they could continue to watch. By the sixteenth I was panting as hard as Sandra who was obviously excited by the ordeal.

Her husband couldn't wait for her cuffs to be removed. He just ripped off her suit bottom and buried his dick inside her, grabbing her red cheeks to pull her forward while she wrapped her legs around his waist to help drive him into her.

Jon took off her handcuffs but she continued to hold on to the trapeze with a look of pure ecstasy on her face.

I pulled down Jon's suit and flopped on my back for him to lay on me with my legs around his butt pulling him into me as deep as possible.

After we came I sat up to see everyone was naked and lying back looking satisfied. Jon sent me to get a bottle of champagne and glasses. We sat around in a circle cross-legged like kids around the campfire to check out each other's bodies. They had Sandra stand up to show her red butt. By now it had faded to the point it just looked like it was blushing. Showing it off while they felt it to see if it was still warm seemed to excite her again. She said, "That was a wild experience! Don's birthday spankings have never turned me on. I just let him do it because it made him excited. Somehow being tied with a bunch of people watching me almost naked while my butt got hot and tingly was really exciting. I was about to have an orgasm when she quit. Could you tell?"

They all agreed that it was obvious she was getting off on it by the look on her face and the way she was pulsating. Jon had taken out my nipple rings since they were so obvious in my white top but had left my pussy rings in. One of the girls noticed them and asked me to come over so she could see them better. She thought they were beautiful but shuddered at the thought of putting them in. I again wanted to prove how much I loved Jon so I told her it hurt awful but I wanted them as further proof of my love for Jon.

I think that alienated the other women especially when their husbands or boyfriends asked them why they had never done anything to prove their love. Sandra said, "Oh she is just making a big deal over it. It is just skin. I had my ears pierced in three places for my diamonds. I'll bet that hurt just as much. I'll bet she spanked me harder than Jon ever did her."

I didn't know what to say. There was no way to prove how much it had hurt and I didn't want Jon to look sadistic. I just sat there thinking of an answer when she continued.

"I'll bet she lied about doing twelve of those leg-ups too. I am in great shape and I could only do seven."

"Yes I can! I already have. If I really pushed I could do fourteen."

Sandra squealed, "That's a bet. If you don't do it I get to give you twenty eight lashes."

I was trapped but I didn't care. I wanted to prove myself. I told Sandra defiantly, "I am not only stronger than you but braver too. You know spankings to your butt don't really hurt that bad.If I don't make it I will take the sixteen you took on my butt plus sixteen more on my front!"

Sandra smiled evilly and said, "Really? You mean I can turn that cute white belly, your breasts, and even your pussy all red?"

"Yes but don't get your hopes up. I will do fourteen."

"You better! I am going to hit as hard as I can. Just like you did!"

That wasn't true. I could have hit her harder but I just said, "Do your worst if you get the chance!"

Everyone cheered and I felt very proud of myself.

I was happy that I received as many compliments as Sandra when I jumped up to the trapeze and hung there for a moment to show them how my stomach went concave.

It was exciting to flash my pussy in front of all those people, I felt like I was on stage again and smiled at the hungry look on the faces of the men as I not only lifted my legs but spread them too. I did them slowly to let them see my muscles work which was a mistake. The excitement plus the fact I was still tired from the sex and the extra effort to slowly spread them and bring my knees up next to my breasts made me realize I was not going to make it. My legs shook as I managed to lift them up for the thirteenth then I gave up sobbing from the exertion.

I was so tired I dropped to the floor panting as I sat there recovering Sandra said, "Rest up because when you are ready to be handcuffed to the trapese I am going to turn that cute white body maroon. Remember? You said I could hit your front as well as your butt."

That scared me. I knew she ws strong and I had never received thirty lashes all hard.

"Please don't hit too hard. I went easy on you."

"I didn't ask you to go easy. The point is to punish for failure. It was your choice to go easy. I plan to punish you for all the bragging you did that you could do so many. You set the goal and you failed."

One of the men yelled, "Way to go Sandra. Let's see if you can make her scream. She never did at the last party."

That really alarmed me I turned to Jon and begged, "You won't let her hurt me badly. You will stop her if she hits too hard won't you?"

I sobbed at his answer.

"You asked for this. I hope she really hurts you so you will remember that your punishments are to be set by me, not at your whim."

One of the women yelled, "All right! You have carte blanche Sandra. Let's see if you can turn her maroon."

Sandra howled in glee and told them I would be maroon from my armpits to my thighs."

I sat there and had to admit to myself that I could have done fourteen if I had just done them quickly instead of showing off and began to wonder if I had set myself up for failure just to show my courage.

By then I was rested so Jon got the padded cuffs and locked them to the trapese as two men lifted me by holding on to my thighs. Then Jon said "I have something to keep her accessible."

He went into the dungeon and brought out a steel pipe about four feet long with manacles welded to the ends which he attached to my ankles while the men pulled my legs apart to stretch the muscles in my thighs.

Someone yelled, "Wow! The lips of her pussy have opened. The whip can hit right on her clit."
