He stuck his dick into me from behind and I let my breasts roll on the tacks while he pushed down on my shoulders to have two more orgasms in spite of the fact that he was so excited he did not last long.

When he untied me my boobs were covered with little drops of blood and I could feel big welts on my ass and my pussy was burning. When I spread the lips I saw two skinny welts on the inside of the lips.

He was really impressed. He told me I had earned an 'A' for the entire couse and since my butt was too sore to ride my bike he let me ride on my belly home in the back seat of his car. I was a real heroine to the other pledges and actives. They had never heard of anyone that took over thirty and they had not received a guaranteeed "A."

I took the next day off but to my surprise my butt didn't hurt by that night and the welts and bruises were gone in three days.

By the night of the party I only had a little over a hundred demerits which I thought would be easy since they would be spread out over the night.

Kay told us that after a long meeting with the actives they had decided on changes to make it easier on us. I was not worried anyway since only the light whip would be used but the changes did seem to make it more equitable.

"We agreed that the boys seem to hit harder when the girl is hung helplessly from the ceiling. Sue suggested that no-one would be hung from the ceiling after you pledges for less than fifty lashes at five dollars because very few of them could afford to pay two hundred and fifty dollars. All of us don't mind being spanked very much so butt and thigh lashes will be two dollars rather than five to encourage them to hit on those places rather than the more painful areas.

We also decided they should pay for sex depending on it's level of degradation. Straight fucking which we all love will just cost ten dollars, butt fucking fifteen, blow jobs, or tit fucks twenty."

The she gave us the "Grass skirts." They were just one layer of thin green plastic strips that barely covered our butts.

Since Margo, an active and me had the biggest boobs we were assigned as greeters to welcome them with a kiss and hand out the list of activities. The boys came in raincoats which when removed revealed the boys just wearing loincloths. I love boys butts and it was really fun to compare them all totally bare.

The activities would not start for an hour to make sure everyone was there and to let the boys have some drinks to loosen up. During that time the boys would kiss and fondle us so I was excited by the time Kay announced it was time for the pledge whipping.

I realized we would all be whipped at the same time when they threw five ropes over the huge ceiling beam to pull us up on our toes then the outside girls had their legs pulled apart to tie them to rings on the walls then our legs were tied to each other's so we ended up looking like five "X,s."

Then Kay announced that we would get ten lashes on our butts, ten on our breasts and ten to our crotches. The boys scurried to get behind us to see the lashes hit our butts.

It turned out to be pure punishment because the lashes were very hard and too far apart to work up to orgasm. We were hit one at a time so they could savor the sound and effect of each lash on each. I was in the middle. I would hear a loud "Snap" then a moan then a little later another "Snap," and gasp then a sting and burn to my butt. By the time it was my turn again the pain had gone away so each lash was like a first one before excitement could override the pain. The boys loved it because it gave them time to savor the way each butt flattened and reddened with the lash. They would cheer at a particularly hard lash that would make the girl yell.

When they got to our breasts I was really vulnerable because I had the biggest ones and the boys loved to see them bounce when hit, encouraging my whipper to hit upward to make them lift and bounce violently.

We were all crying by the time they whipped our crotches diagonally to cover every inch of our splayed pussies.

After we were let down the evening did not go as planned. We pledges hardly got whipped at all. I was glad because it really took all my will power to kneel with my boobs pushed out while they were whipped.

The actives really got it. The boys were not deterred by the fifty rule because they pooled their money to get even with a girl that had pissed them off and the pledges were only interested in punishing actives.

Sue must have pissed off a lot of them. She got a hundred and they all fell on her breasts and crotch. They could not wait to get to her. One boy would be whipping her tits while another whipped her pussy. It must have hurt awful but later she admitted that she was finally able to have crashing orgasms.

Kay got seventy five from the pledges of the frats since she was pledgemaster. It was over quickly though because three at once hit her with one at the back swinging the whip like a windmill to go between her ass-cheeks with the tips hitting her clit. She was nearly hysterical by the time they finished but more from orgasms than pain.

The actives made a mistake in not wanting to be restrained and making the lashes so expensive. If they had been tied they may have got enough lashes in a row to get off on it. The boys knew that this might be their only opportunity to hurt and humiliate the actives so they made them get into humiliating or painful poses to give them a few lashes before moving on to another pose or another girl before they could get excited by it. The boys also cheated them by having them bend over with their legs apart or get on their hands and knees for butt lashes. Actually the poses would make their pussies pooch out from between their legs so low lashes to their butts also hit their pussies.

The other thing the girls did not expect was the boys combining sex with pain. When a boy laid on his back to put an active on his dick another boy would whip her breasts as she gyrated wildly to get the boy under her to cum as soon as possible. On blow jobs their butts would be whipped.

We pledges were for the most part just used for sex. It was great to have all the different sized and shaped dicks in us while we watched the actives that had been mean to us scream and cry as welts were put on them by the boys who hit as hard as they could to get their money's worth. My only problem was that I seemed to be a natural for tit fucking which was just painful and humiliating. I would be put on my back with my head pressed forward by a wall or couch so when the boy lunged forward to press my breasts into my cheeks the head of his dick could go into my mouth. When he came his cum would splatter all over my face and the next day my breasts were sore and bruised.

It could have been worse. When Margo was tit fucked two boys would hold her legs wide and up to her head while another whipped vertically on her slit to make the thongs hit her clit and tender ass-hole. Her howls and screams just seemed to encourage them to hit even harder.

The only problem I had was that the boys would be so excited when they fucked me they could not last nearly as long as I needed to cum.

I solved that problem just before the party broke up. I went up to two boys sitting on a couch drinking and asked them if they had any fantasies I could perform for them. They told me that they were broke and fucked out so I told them that as a reward for contributing all their money I would do anything they wanted for free.

They decided it would be exciting to have me hung spread-eagled again while they fucked my butt and pussy at the same time. They really must have fucked a lot because they didn't even get hard until they had whipped my breasts and pussy to a dark red and then took a long time to cum. I had orgasms one after another until I was so exhausted I was just hanging there shuddering under their thrusts.
