I looked at June's rings enviously while Dad used them to pull her nipples out and around till she was gasping in pain or excitement. I couldn't tell which.

"Jim, They both have lovely big firm tits. You should be proud. I love to see them bob around on their chests while being whipped."

"Yeah I hear you. I like to watch them just when they are walking around. They need to stay in shape. I think I will have them do exercises every morning with the girls on TV. I have daydreamed what those girls would look like doing them naked. The side-straddle hop should be wild."

"Yeah. We have a lot of privacy at our place. We could have them run naked on the trails while we follow them on horses. If they slow down we could encourage them a little with buggy whips."

The idea of performing in front of them sounded exciting but I dreaded being run till I dropped from exhaustion. Being out in the open excited me enough to stop worrying about it. as Bobby continued, "Dad and I run my mom and my sister on the trails. The idea that some stranger may be watching them with binoculars adds some excitement for them."

When Jim got up to go to the bathroom while Bobby made more drinks I whispered to Mom, "I won't hit you very hard if you are easy on me. I kind of want to save them for Bobby to whip."

"I'll try but I can't guarantee anything when I get really excited. I just hope they don't get so excited they cum too soon."

Bobby came out of the kitchen to meet Dad coming back from the bathroom. He had a sack in his hand.

"I found these in the kitchen.These clothespins might help get their tits a little more sensitive for the whipping."

Dad agreed and they used up all the pins in the sack. We had about twenty pins apiece on our boobs when they were done. I know it doesn't sound like much but the longer they stay on the more they hurt especially since they would idly tug on them or flip them while they sipped their drinks. Mom began to whimper a little and I asked, "Can we take these off now. My tits are plenty sore enough for their whipping."

Bobby made me beg. "Say please take off my pins so I can be fucked while my tits are whipped very hard." xray Dad seemed to enjoy hearing me plead for my whipping so he made June beg for it too.

It hurt almost as much having the pins taken off as when they were put on as the circulation returned to the spots. They teased us by taking off their clothes very slowly then having us lick and suck on their dicks till they were sure they were hard enough.

It felt wonderful to feel Bobby's dick stretch the lips and bury itself till it was pressing against my cervix. I could have got off easily just by fucking him but I knew he wanted more. I whipped Mom's tits just hard enough to make a satisfying, "Smack" she retaliated in a few seconds and then we fell into a steady pace. In spite of our agreement the lashes began to come faster and harder as pain and excitement grew until we just fell over on our sides onto the floor gasping as we kneaded our red swollen breasts. They must have cum much earlier because when I reached out to fondle Bobby's prick it was completely soft.

They just let us lie there for awhile then Bobby went out to his car to get his special salve to put on our breasts.

"Jim this is great salve. We use it on the horses. It stops the pain almost instantly. Girls can take almost anything as long as they know it can be stopped after they cum. If you really want them to hurt, you just hold off on the salve. Once they cum they can't override the pain with excitement."

As Dad was putting the salve on Mom he said, "You girls are really amazing. I would never have hit you as hard as you hit yourselves."

Bobby answered, "It is mainly a matter of timing. You can't just start out hitting hard. You have to let their excitement build and hit harder as they get closer to cumming just like they did. Kathy. My dick is sticky and itching. Clean it off for me with your tongue."

Dad hurriedly said, "Let June do yours for you. I want Kathy to do mine."

When I had licked it clean I put it between my tits and began sliding forward and back to dry it off. He really liked this especially when I had my lips close over the head of his dick on the backstroke. I noticed Bobby was having June do him the same way but it wasn't enough for him so he began to spank her upturned ass with the whip to speed her up. Dad quickly copied his action timing the strokes to hit my ass just when my butt was at the highest position to make me go faster and harder till he came on my face and tits.

They had us lick the cum off each others face and breasts while they directed us to any spot we had missed.

By then we were all pretty well fucked out so we had another drink and then went to bed for a nap.

I woke up first and went to the kitchen to make coffee for all of us and some sandwiches. Bobby and then Mom and Dad came in a few moments later and we sat around naked drinking coffee and eating sandwiches. Bobby was fascinated with Mom's nipple rings and sat there tugging at them till the nipples were extended,

"This is fascinating. I wonder how much weight she can stand pulling on them?"

This fascinated Dad too. "We can find out. I have gobs of fish weights we use to hold down a fish net."

He went out to the garage then came back in straining under the weight of a large tackle box. He opened it to reveal hundreds of four ounce fish weights. Mom looked alarmed.

"Don't want her tits stretched to sag. I think we should hang her upside down so her tits will be pulled up. Don't you agree, Bobby."

Nobody bothered to ask mom as she looked at the box with wide eyes and held her hands over her nipples. "Oh God! Jim that much weight will rip off my nipples."

"We don't expect you to take all of them. The rings would pull off long before the nipples are torn. Just take as many as you can. Bobby, Use that wire to make hooks for the weights so we can hook them on this."

While he talked he made a large loop of heavy fish line to tie to her rings. This alarmed Mom even more. She had probably thought there would not be enough room to put many of the weights in the rings. Bobby frantically bent wire and had about forty of the weights ready by the time he had Mom tied upside down to the ceiling with her arms tied behind her. When he was satisfied with her position he said, "We will quit putting them on as soon as you tell us to quit. I don't want you to quit at just a little discomfort though so when you say quit you will get one lash to your pussy for every weight left over."

I couldn't really emphasize with Mom because I had no idea what that would feel like. I was just as fascinated as the men as I watched weight after weight added to the loops. The first several didn't seem to bother her much in fact she moved her body to make the weights swing like a pendulum. She finally screamed, "No more! They are tearing!" by that time she was wearing forty of them and her breasts were cradling her face with her nipples stretched to her ears. It was made even worse as she absorbed the fifteen lashes to her pussy as the weights swung an bobbed with each lash. It hurt too much for her to cum and she was sobbing like crazy when they let her down to let the weights rest on the floor till they had cut the loops.

Dad knew he had gone too far. "I am really sorry honey, I was just fascinated by the way your tits and nipples stretched. I was hoping you would get into the pain."

"It is alright. It is over with now. I am sorry I couldn't take any more weight but I got so frightened the nipples would tear. My fright would not let me get excited enough to overcome the pain. At least you know I love you that much."

"Oh yes. And I love you more than I can say." He was hugging and kissing her now and I felt left out.

"I will do that for you Bobby!"
