Heading home from college I pass the grocery store where I work part time. Harinder who owns the store with her husband Rohan waves at me. I smile then I hear someone shouting.

— "Hey George". -

Turning my head I see Trevor my best friend on the opposite pavement.

— "Your sister home now?" he asks. -

— "Yeah a few days ago Trev. She enjoyed her holiday and she's going to search for a job" I reply. -

— "I'll come around after work one evening to meet her" he shouts as a lorry drives by. -

My sister Sharon had been away at college for two years. She did visit us a couple of times though. After college Sharon and her friends travelled across Europe with one of her friend's older brother. She had a wonderful time however it meant we couldn't spend the holidays together and now I was at college.

Sharon is twenty, about 5ft4, long straight brown hair, very pretty, slim, boobs bigger than a handful and a curvy arse. She always received high grades at school and college, was talented at sports, lots of friend's and always had boyfriend's.

I'm 6ft, eighteen, short dark brown hair, slim, not handsome, shy, receive decent grades, rubbish at sports, Trevor is my only friend and I haven't even kissed a girl.

Trevor moved to this town about two years ago. He and I became friend's as we enjoyed books and movie's. He's a virgin too and rubbish at sports. He's about my height, short blonde hair, quite handsome and chubby but he had lost weight as he's been lifting weights. He hadn't met Sharon before as she was at college.

Trevor didn't go to college after school and instead he got a job at a factory. He hoped he would meet a girl there but so far he was unsuccessful.

When I arrived home Sharon and mum were in the kitchen cooking. After dinner we viewed a movie than I went and did my homework. Sharon came into my room later and said she was happy we could be together again. We had always been close even though she was popular and pretty while I was a nerd.

I said that Trevor would come around to meet her and she was excited to meet him. After kissing me on the cheek she went to her bedroom.

After college and working at the store the following day I arrived home. Mum was setting the table for dinner and when I entered the lounge I heard laughing. Sharon and Trevor were on the couch chatting and joking around. Nice they're getting on I said to myself.

Over the next few weeks Trevor was around our house often like when we were at school together. He'd usually be there when I arrived home viewing a movie on TV with Sharon and mum...

I was heading home from college early one day. Not due at the grocery store for an hour or so I decided to go home and have a snack. Mum would be at work but Sharon would be there unless she had gone out with her friends.

In the hall I hung up my jacket and put my rucksack on the floor. Entering the kitchen I took a chocolate bar from the cupboard and made my way to the lounge. The door which was always open was closed. I pushed it open slowly and heard moaning noises. Then as I pushed the door further open I see Sharon naked on all fours on the sofa and Trevor naked on his knees behind her thrusting his cock in and out of her bald pussy.

I'm unable to speak as I see my sisters big boobs swaying back and forth and her arse cheeks wobble as Trevor's groin snacks against them.

— "Ohhhhhhh fuuuuuck"groans Sharon as Trevor thrusts his thick cock into her. -

His cock is bigger than mine. Easily seven inches and much thicker.

— "Fuck me haaaarder" groans Sharon so Trevor pushes in harder. -

Though I was aroused I was also angry that my best friend was screwing my sister and that neither of them had told me they were at it!! Pulling the lounge door closed I walk to the front door with the chocolate bar in my hand and head outside. My cock still erect I walk to the bench at the end of the road and sit down.

Trevor had been a virgin however seeing him perform with Sharon he must have been fucking her for a while as his technique was impressive. As for Sharon she rarely swore!!! I sat on the bench until my cock was soft then I headed to he store.

Arriving home after work Sharon and Trevor were on the sofa talking. I didn't say anything to them and told mum that I'd eat dinner in my room as I had plenty of homework. Though Sharon and Trevor were unaware of being seen screwing they could've seen my jacket and rucksack in the hall afterwards.

That evening after completing my homework I decided to view porn on my computer as I'd been horny earlier. This was the end of the nineties so to view a porn image you had to wait for the image to upload on the screen. However I was unable to get hard and kept imagining Sharon and Trevor. Though I'd been hard seeing them earlier now my cock was flaccid so I went to bed.

The next few days I didn't speak to either of them though I think they were to busy to notice. Then one evening after work I came home and mum was in the lounge. After saying hi I went upstairs and as I passed Sharon's bedroom the door wasn't shut completely and I could hear moans and bodies slapping. They were fucking even though mum was home!!

I went into my room, slammed the door shut and lay on the bed. The following day I saw them in the kitchen with Trevor's hand inside Sharon's shorts. She was moaning into his shoulder as he pleasured her pussy. That evening I asked mum if I could go and stay with Aunt Vicky. She was mum's sister and lived about ten minutes walk away.

— "Cause Sharon and Trevor are dating?" she enquired. -

— "Yes mum. Hearing them having sex and the fact that Trevor dated my sister without a word. Then they both kept it a secret" I replied. -

— 'They've a right to be happy George" said mum "Though they shouldn't have kept it secret". -

— "I can't concentrate on my homework" I answered. -

— "I'll ask Vicky and see if you can stay at her place. Though I would prefer you to stay I want you to earn good grades at college" she replied. -

She spoke to auntie and she said she would be most happy for me to move in with her. When I was packing my things a couple of days later Sharon came into my bedroom.

— "Why you moving out George? Thought we would be together again when I came home from college?" she asked. -

— "Would have been fun to" I replied. -

— "Just cause I'm dating Trevor it don't mean we all can't have fun together. Trevor says your jealous of him" she then said. -

— "Jealous?" I snorted "Having sex with you isn't a fantasy of mine". -

— "Jealous that he's in a relationship with me and your a virgin" she retorted. -

— "You don't date your best friends sister" I replied angrily "Especially when you don't even ask him and then you both kept it a secret". -

Sharon left the room while I finished packing then I headed down to mum, kissed her and headed to aunties with my cases.
