One day Mom told Bill to dust the book shelves since he was now taller than her. On the top shelf he found a book called "The Kama Sutra." That was great! It showed us a lot of new positions and also taught us to mutually suck each other.
One Friday my folks said they were going to spend the weekend at a friends house and said it would be no fun for us so we would stay home. There were microwave dinners and a roast in the oven for sandwiches.
I had always described my and the other girls whipping in detail for him since it made him excited. They were hardly out the door before he said, "You know the stories you told me about the whipping really made me excited. I wish I could see it once. It would be more exciting if you were tied."
I said, "We can't. We don't have any rope and my whip would hurt too much to let me have an orgasm."
"I have thought about that. Mom threw away some sheets and I saved them. We can cut them in strips and braid them into ropes. I watched them hang the chandelier, it has a huge hook that will support you easy. I took a big dowel from wood shop. I can slit a couple of my old belts in two to nail to it. It should just turn you red."
The idea excited me and I knew it would really excite him so I agreed.
He got the sheets and helped me cut them in strips then left me to make the whips while I braided. It seemed extra exciting to know I was making rope to tie me and make me totally helpless and at his mercy. I didn't have to worry about a specific number of lashes because I knew he would whip me until I couldn't cum anymore. I had never found out how many orgasms I could have in a row and was anxious to find out. Also now I would not have to be silent I could scream all I wanted since we had no close neighbors and I could tell him to hit me harder if I needed it.
He finished the whip before I had finished the rope. It made me wet just looking at it. He had sliced his belt into six narrow strips the length of his waist, thirty two inches. Each braid as the rope got longer increased my excitement.
Since we didn't have any rings in the floor he had me stand on a heavy marble-topped coffee table so he could tie my legs to the legs at the ends. This brought my feet about three feet apart and he told me that the lips had opened a little on my pussy. I wanted to see it and also realized I had never seen myself getting whipped so I asked him to bring in Mom's free standing three way full length mirror. He was right. The slit of my pussy had opened slightly but I wanted it open even more. I was curious to know how the thongs would feel if they could actually get to the pink inner lips and my oh so sensitive clitoris. I had him pull my legs apart until my feet were at the edge of the table. My tendons in my inner thighs showed as my legs trembled from the strain and pussy opened to show all the inner lips and an opening big enough to put in his thumb. He could not resist doing that which made my clit hard enough to make a bulge. My excitement rose just at the sight of my pussy so vulnerable to the lash. My only other request was that he get naked too so I could watch him get excited. There was nothing to see. He was already rock-hard just anticipating what was going to happen. He got the kitchen stool to put our make shift rope over the chandelier hook and pulled it down to stretch me. I had him pull harder fascinated to see my boobs raise and tighten into hard balls as my stomach went concave and my waist shrunk. I didn't let him stop until my joints began to dislocate and real pain began. He tied the end to the legs of a heavy cabinet and grabbed the whip but I asked him to wait a moment so I could gain more excitement from the pain and the sight of my body so helpless.
He really made me feel proud. He felt all over my body and said, "Jesus Sis, you are more beautiful than ever stretched like that. Look at yourself in the mirror." I had been and knew I looked great. I pictured myself in front of a large crowd of people who would be cheering. I was proud of my body anyway now that I had boobs and was so firm from gym classes and working out with the tapes but now my stomach was even flatter and my tits pointed up proudly. My pussy lips were open as wide as possible without pulling them open more with fingers. I wondered how the whip would feel with the thongs going inside. I told him the teachers would start on my butt, then my thighs, then my lower stomach and finally my pussy.
He said, "I want to add one more thing. I am going to whip your tits too. I'll do your butt,thighs,tits, and then work down your stomach to your pussy."
I said. "That will probably hurt a lot but I want you to hit fairly easy at first then harder until I am screaming. Ignore my screams even if I beg you to quit unless I scream 'Mercy.' That word will mean I can't take anymore. I want to take at least fifty lashes. That will be five more than the amount I took at school. Give me fifty even if I yell 'Mercy' Keep giving them after that until I yell 'Mercy.' I want to know how much I can stand. If by twenty the whip is not leaving welts you will know you need to hit harder. I want to see my skin striped."
He stood at my side to do my butt so I could see the whip coming and brace myself. The whip he made was perfect! It stung and brought on heat but no deep pain like my braided whip. He must have thought I could take sixty because he gave me fifteen to my butt. When he finished with my butt he began encircling my thighs with the whip for another fifteen. I could see it coming through my legs just scraping on the bottom of my pussy. Then he started on my tits. By then it was leaving stripes and we both were excited by the way they compressed and shuddered at impact but my excitement really took off as the whip slowly moved down my stomach closer and closer to my pussy. I began to cum just as the first lash came across it but then he went behind me and began bringing it up between my legs so I could see as well as feel one or more thongs bury themselves in my slit.
At ten on my pussy I had a massive orgasm and screamed, "Hit my tits and start down again!"
My orgasms continued as stripe after stripe made my tits distort then swell. Then he started down then stepped back so just the tips of the whip dived into my pussy ripping the lips wide open until I was so overcome I moaned "Mercy".
New kinds of orgasms started because he got so excited he jumped up on the table facing me and began pumping into my now sopping wet and tender pussy while holding on to my shoulders and biting my nipples. I don't think I ever came that hard again. I still think about it when I want to masturbate.
After he came we were both dripping sweat and I was burning hot so we took a cool bath together in Mom's big tub. He really made me proud by saying, "God! You are awesome. You took over sixty lashes as hard as I could give them before you moaned 'Mercy'. It was perfect since I was going to quit then anyway."
We washed every part of each other's bodies. We were both amazed to see my redness and welts going away from the cool water and his caresses. Then we laid back to enjoy the swirling water when he turned on the jets. That was a mistake, all the soap we had used to wash each other began to foam like crazy and began to run over the top. We wasted about an hour of our time together cleaning up the mess. When I was laying over the edge of the top to wipe up the bottom he began to play with my pussy then he stuck his dick in me. It was great! It seemed like he could get in further than ever that way and it left his hands free to pinch my nipples and clitoris. He came before I did so I told him I would like to do it again that way only he should make me hot first by slapping my pussy with his whip.
