When they had all cum we sat around sipping on beers the boys had stolen from their dad's. Jim asked me how I felt and I told him I felt totally drained but he said that he meant how did I feel about the pain I had ordered with my slip. I said it was not too bad and then I turned to Marcie and said, "Marcie. You are supposed to be my friend. You spanked a lot harder than the boys and you really enjoyed doing it. I'll bet you came just from torturing me."

She looked sheepish and didn't deny it. "I'm sorry. It was just so damn exciting. In my mind I felt everything that was happening to you. Why don't we just burn the rest of the slips and you can do to me what I did to you so we can go back to just having the boys spank us."

That was strange. We always referred to our whipping as spankings. I guess that sounded less perverse. I though about it and then got mad at her again.

"No way! At least not yet. You must have some terrible things in your sack to want to wimp out this soon. You are going to have to suffer through at least one of them.

Marcie whined, "No, please! I threw away all the easy ones when you made me mad."

That convinced me she should really suffer since I had left easy ones. Jim and the other boys agreed with me. Jim said, "Fair is fair. You should be willing to have things done to you that you wanted to do to your best friend."

Marcie sobbed but had to agree and pulled out a slip. Jim read it aloud.

"It says that ten alligator clips will be put on each breast with four ounce fish weights hanging from each while her legs are tied open and he pussy is held tight to the splintery log. Then her arms will be pulled up to make her do a back bend all the boys fuck her from behind till they all cum. While we are fucking her the clips will be whipped off by Jill with a willow switch."

Now I realized how we thought. I had burned off the hair because I was jealous of her bush that seemed to make her more mature than me and had her eat pussy because I knew she hated doing it. She was jealous of my big breasts and knew I hated having them hurt and being fucked in my ass. I could see that her slips would involve a lot of tit torture just as all mine ended with her having to suck cocks or pussy.

By then they had made a lot of padded leather manacles to put on our wrists and ankles so we would not get rope burns. They had her lie on the log with her pussy at the end. She let herself down gingerly then gasped as her legs were jerked apart letting her pussy sink into the splinters. Then they used a shovel to jerk up the log to put a rope under it to tighten at the top of her butt. Her gasp let me know more splinters had stuck her. Then they put manacles on her wrists and lifted the front of her body until it was straight up which caused a strain to her back and more weight put on her pussy now open and pressed into the splinters. At the last moment they decided to tie a rope to her hair to tilt her head back out of the way.

Once she was tied I put on a clip with a weight on her breast. She howled, "No! It is biting me terribly!"

The thought that she would want to do that to my precious boobies made me mad so I stretched out her nipples so I could put two weights on each one. Then put the others as close to the nipples as possible enjoying her screams of anguish.

I was no math whiz but even I knew her tits were holding up five pounds. You could see they were being pulled clear to her armpits and had changed from firm round balls to a pear shape.

At least the guys were nice enough to push vaseline into her asshole. Even that made her squirm which I knew tortured her pussy.

I did not start whipping them right away. I watched in fascination as the weights jumped and swung jerking her tits around while Bill just stood in one place and jerked on her hips to push and pull his dick in and out of her asshole bringing screams as her pussy was scraped on the log.

To my absolute amazement I realized she was getting off on the pain to her tits while being reamed from the rear.

When Bill came and pulled back Tim took his place and jerked faster and harder. The weights jerked and swung like crazy. If they had not tied her head back they would have hit her face.

Marcie began to scream, "Whip them! Oh God! Whip them."

I did not hit hard enough at first to make them come off but the switch jerking on them must have really hurt bad because Marcie screamed, "Harder! Get them off me!"

I began to hit really hard but it was pure luck when I hit one since they were jumping so much most of my lashes just left deep red stripes. I continued to whip them while the boys changed places and they were not moving so much. I was ashamed to admit that I was near orgasm from hitting her since I had thought that she was terrible to get off from hurting me. The closer I got to orgasm the harder I hit until the last clip tore loose to fly across the room.

When they let her down and laid her on an old mattress the boys had found I felt terribly guilty. Her poor tits were covered with welts when they had crossed over and where the clamps had ripped off there was blood.

But the terrible part was her poor pussy. It was covered with blood. We were all relieved when Jim wiped it with a wet rag to see there was no deep cuts, She just laid there and whimpered as several big stickers were pulled out.

To make her feel better the boys caressed salve on them. To my amazement that must have stopped the pain right away because she looked up at Jim and said, "Let me thank you." He knew what she meant and stuck his dick in her mouth while the guys kept caressing her tits and pussy.

We shared the last beer while she gently caressed her sore boobs.

"Oh Jill. They hurt awful. They will be sore for days."

"Yeah, and you were going to do that to my big boobs. That may have ripped them off. Aren't you ashamed."

"Yes I am sorry but I have always loved seeing your tits whipped. I even daydream about it. I thought the clamps would make it worse and they really did. I am not mad at you I deserved it. Please tell me you enjoyed hurting me as much as I was excited hurting you."

"I am ashamed to admit it but I did. I came when that last weight ripped off your nipple."

Marcie giggled and said, "So did I."

We were all amazed at that and told her she was fantastic and should become a spy when she grew up because she would never reveal our country's secrets.

She told me later that made her feel proud and that she would just consider the torture we gave her training for the day she would be a spy.

The next day she met me at school all excited, She had me follow her in the bathroom and into a cubicle to pull down the top of her dress to show me her boobs. I was shocked! There were lines of purple bruises covering them and even a few scabs where the skin had broken but this was not the reason she was showing them to me.

"Jill! Look at them! They are bigger! You were right! Spanking them makes them grow. I am glad now I put so many tortures to the boobs in my slips now. by the end of the year they may be as big as yours."

I looked at them closely and felt them. They were harder than normal and I was sure they had just swollen from the whipping but I agreed with her since I was sure they would get big since her Mom had big boobs. I know it seems cruel but I wanted her to think the whipping helped so she would not get mad at me if I got really excited and hit them very hard.

I began to look forward to the weekend sessions even more because Tom had no imagination and just wanted to spank me easy so I had no marks and evidentally being older lost interest in fucking me every day. He began skipping days and even then had to whip me longer for him to get excited. By the time the weekend came I was almost as desperate for ultimate orgasms as Marcie.
