Secret Agreement

Note : This story is completely fictional!

We were 20 students of medicine (10 males & 10 females, by mere chance) in a Yorkshire (England) university. In our third year, we studied biochemistry under a very tough professor. Any student who passed in that subject found it relatively easy to continue until the last year of undergraduate study.

All of us were scared before the final exam of biochemistry so we studied very hardly. One of our classmates said" You all know that if we all pass this test, then we can call every one of us doctor even though there are still 3 years ahead of us". Of course, none objected this viewpoint.

Surprisingly, the biochemistry exam was an easy one and all of us made it. A classmate suggested that we celebrate after finishing all the exams by carrying out a sexual orgy in the hall of his large apartment. Another one insisted that the orgy will involve us only "the would-be doctors" simply because the success belonged to us. Another one hoped that anything will go & we had to drop all the barriers. All agreed.

The orgy was to be held at a Friday night & each one of us would tell his family, or boyfriend, or girlfriend that he or she would not be available all that night due to a medical assignment in a hospital outside Yorkshire.

Two hours before the orgy, a female classmate apologized because her grandmother was in the last hour of her life "dying". A male classmate (Timothy) said that he would bring his girlfriend as a substitute since there had to be a balance (10 M versus 10 F)! We appreciated his & hers liberal attitude.

At around 9.00 p.m, we started to gather in that apartment. Timothy came half an hour later. His girlfriend was to my great astonishment, my sister Avril. When we saw each other, a deep blush covered our faces. On the spot, I whispered in her ears that nobody would know that we are brother & sister including Tim and we had to avoid each other during the orgy activities.

At around 10.00 p.m, one guy announced the start of the orgy. Within few minutes, all the boys & girls were completely naked. Every male was allowed to do anything to any female, and vice versa. Hand jobs, blowjobs, kissing, petting, fucking (straight & anal), and vibrators were every where.

I glanced at my sister's body when she stripped for the first time in my life. She was stunning & looked like Pamela Anderson. I also noticed that she was very active in the orgy. At one moment, she arrested a guy between her thighs with her legs over his back. The guy was delighted & said to her "Please don't press your cunt's muscles on my cock because I'll cum fast. Oh you sweet pretty sexy thing!" .
Later on, the guy was replaced by another guy & Avy pleased the other one & he told her that he was in heavens.

The second guy removed himself due to his approach to Cumming as he told her. A third guy inserted his cock in her pussy changing the sexual position but after a little while he shouted "Oh. Jesus Christ! What an angle! My balls are about to burst!". He also left her for another girl.

Some of the guys & girls saw me not concentrating on my own sexual pleasure & that I kept looking at Avril. When Avy became available, 2 classmates (male & female) encouraged me to go for Avy. When I refused, the man shouted at Tim "This man, Dave, does not want to fuck Avy". Tim became angry & said "You, Dave, is breaking the rules of this orgy. Come on have a go and you will be very grateful!".
Upon the pressure, which came from all directions, I moved towards Avy reluctantly.

I started kissing her & holding her tight between my arms. Fire spread through my body & I became very aroused. One step led to another & I found myself fucking her straight & anal. I discovered that Avy was the sexiest girl I ever encountered in my entire life.

When the orgy was over next morning, we went separately to our house. In the house's garden, we talked about last night's orgy. We reached a decision that from now on, "We are more than a brother & sister. We will become intimate lovers. If we marry, we will continue to fuck. This is a secret agreement between 2 wise consenting adults & it is nobody's business. It is also not the reactionary law's business,as well".
