I had been doing fifth grade work so I graduated that summer to sixth. Mom was overjoyed. She said she would throw a party for me. By now I had found four girls that got orgasms from whipping so I invited them. Two of them brought their brothers. It was obvious to me their brothers were fucking them from the sneaky touches to their pussies when they thought no-one was looking. I took them aside and told them I knew and that it was alright since I was fucking Bill too.
Summer was great since my folks were gone from seven in the morning to six at night. I invited my friends over one at a time. We learned from each other. Bill and I taught the girls who brought their brothers the positions out of "The Kama Sutra." One girl had boobs as big as mine and her brother showed us how to tie twine around the bases of our tits and wind it around till our tits were real hard and throbbing. That made them a lot more sensitive to be whipped.
The girls with brothers also had both parents working. The other two girls had Moms at home so they couldn't come as often. They almost killed off poor Bill. Once they had been fucked they couldn't get enough. They eventually brought over neighbor boys or cousins so I didn't have to share Bill and I got a chance to fuck someone new. None of them were as good as Bill since we had been practicing so long.
The only bummer was that Mom insisted Bill and I go to camp for three weeks at separate camps. It was a real drag! We could hardly wait to get home. We were so horny we almost killed each other the first day home.
The other girls and I continued to work out to the tapes because the boys loved to watch us do them naked. By that fall we looked great. I had an eighteen inch waist and my boobs grew to a thirty four C cup. My mom noticed and bought me some bra's. I hated them and took them off any time she was gone.
That fall we had a new teacher. He was about thirty and a fitness nut. He had a gorgeous body and unlike my old teacher who wore baggy shorts and a T-shirt during swimming he wore a tight suit so we could giggle over the huge lump his dick made in it when he would get a hardon.
Some of the girls had dropped out because of job transfers or other reasons so there were now only fifteen girls in the class. That was great because we could get even more attention and help.
On the first day he said that there was no excuse for girls to be overweight and that three of us would be weighed every day and anyone overweight would get five lashes for every pound over the chart. It really worked! The fat girls starved themselves and lost one or two pounds every week. By the end of the year they looked great.
He said he had also decided to let us choose our position to be whipped. He told me to come forward to demonstrate. When I got to him he told me that my old teacher had told him I was his best student and that I wouldn't be hurt bad. I wondered what all he had told him.
He first tied me in the regular position then hit my butt twice with a wide thick strap. It really stung. He let me hang there whimpering while he explained that this was position one and we would get the whole number of spanks in that position.
Then he untied my ankles to turn me side ways to the class and retied me with my legs spread even further. He said that this hurt a little more and that girls choosing this position would get a twenty percent reduction in spanks. He picked up the same kind of whip my old teacher had used then hit my butt, my breasts, my pussy then hit them all again in that order. By that time I was panting and trembling in excitement. While I hung there he explained the third position was even more painful so it would allow a forty percent reduction.
He took me loose then had me kneel down where he tied my knees to the rings which pulled my legs widely apart. Then had me put my head down on my arms. I knew this opened my pussy lips and brought it back because I could see it between my tits. Then he picked up another whip with some real soft leather thongs and hit between my legs to put four lashes right on my pussy. I almost came and when he helped me up I was so dazed he had to help me button my uniform. He gave me a little kiss then said, "Thank you for helping with the demonstration. I will deduct these lashes from your next spanking if you like."
There was no question which position I would choose although just for variety I sometimes took position two.
He chose the girls to be weighed in alphabetical order. one girl was five pound over. He said that he would allow two pounds grace to allow for water retention. She chose position one and he gave her fifteen spanks that just made her butt red.
The next girl was ten pounds overweight She also chose position one. I think he was disappointed he would not get to whip her big tits. He said, "Forty spanks are a lot to take in one place. Are you sure you wouldn't prefer position two."
She just whimpered and shook her head. I think it made him mad because he hit her harder than the other girl. She had terrible welts on her butt when he finished. I felt sorry for her because I knew she hated to be hurt and told her after school to take position two or three because the whips weren't nearly as bad as the strap. She whined, "I couldn't do position three. It would be too embarrassing. You didn't see yourself. Your pussy was in plain sight and even open a little." She said that next time she would try position two because nothing could be worse than that strap. even the next day she was so sore she brought an inflatable pad so she could stand the pain of sitting.
My friends and I avoided the weight whipping because we were in such good shape but at least one girl was whipped every afternoon for either weight, grades or both. Most of them chose position two after seeing the fat girls butt. I had a great seat at the front corner desk. I was thrilled to see their tits and pussy lips wrenched out of shape by the thongs.
After a few weeks he began reading letters aloud from parents complimenting him on causing the weight loss after all their failures with all kinds of diets. If any of the girls thought he might stop doing it the letters quashed that hope.
My first whipping happened on Thursday. Naturally I went for position three to get my spanks. I had earned thirty two but after discount it was rounded off to twenty. It made me cum like crazy! When he hit me he would drag the thongs up my crack for the next one. My pussy got wet right away and the thongs began to get wet so the pain got a little worse at each lash. At the end the thongs were so wet they made a "Splat!" sound when they hit and caused all of it to burn.I could see every lash hit my pussy and if my knees had not been tied I would have spread my legs more to let the thongs hit inside.
When he finished and helped me up I hugged him mashing my breasts on his chest and said, "Thank you. Oh thank you." He grinned and said, "Now that is the right attitude class. You all should thank me for trying to make you a better person."
It didn't fool anyone. My friends knew I had enjoyed a great orgasm and now all the girls suspected it. I didn't care. They still treated me as a heroine since I did not cry or yell. Best of all, my friends and some of the other girls started going for option three. I loved to watch them get spanked because I knew just what they were feeling and the empathy would get me excited enough to run home for a quick fuck from Bill before my parents came home.
Bill was really excited by my descriptions of my and the other girls whipping. I told him I had no idea where we could get one of those soft leather whips. He said he would look around and try to get one for the week-end our parents would be gone. He found something real close with deerskin. He cut it in strips and nailed it to a mop handle Mom had thrown out. He was waiting for me when I got home. It wouldn't be the same since we didn't dare tie me since we never knew for sure when one or both of our parents might get lucky on the traffic and get home early. I knelt and spread my legs for him. It was perfect! We could hardly wait for the weekend so we could have time for me to be whipped and fucked from behind. I told him I thought it might even be better if he figured out a way to keep my pussy lips open so the whip could get wet faster and easier.
