We are a very ordinary family. Mum, Dad, my sister Lucy and I living in a very ordinary house in a very ordinary town. As children, we had led fairly sheltered lives.
I had just turned nineteen. Lucy, at eighteen, was just under a year younger. Mum and Dad had planned it that way so we would grow up together. It seemed to have worked out. Lucy and I had the usual brother and sister arguments, but overall we got on together pretty well.
In the past couple of years, in fact, we had really stopped arguing altogether. So Mum and Dad felt they were able to stay away overnight and leave us on our own. It had happened a few times without problem. Tonight they had gone to visit friends and would not be back until tomorrow afternoon.
As was usual on these occasions, Lucy and I had ordered a pizza to be delivered. We sat and watched a couple of movies while I helped myself to one of Dad's beers from the fridge. As I finished it, Lucy decided that tonight she wanted a beer. So I went and fetched two more and flipped the tops with the bottle opener.
We finished the beers and each made our way to our room. I switched on the computer and played games for an hour or so. Then I undressed and pulled on my pyjama trousers and got into bed.
Sleep would not come for some reason tonight. I got out of bed and made my way back downstairs to the lounge. I switched on the TV and turned the volume down low.
Flipping through the channels to find something to occupy my mind, I heard the door open. I turned as Lucy came into the room, also in her PJ's. She was wearing a pink set of shorts and tee-shirt top. She flopped down into the sofa beside me.
"I can't sleep, Tom," she said.
Having found nothing I wanted to watch, I threw her the remote. She went through the same exercise before pressing the power button, sending the screen to black.
Thinking for a moment, she suddenly sat up and turned to face me.
"Let's play a game," she said.
Thinking she meant a board game, I told her I really didn't feel like it.
"Oh please, Tom!" she almost implored.
With nothing else I could think of to do, I said OK and asked what she wanted to play.
"Truth or dare," she said with a big grin on her face. "I've played it with my friends sometimes when we're bored. It's fun."
Again I acquiesced without any real enthusiasm.
Lucy insisted on having the first go, so I opted for a dare. She made me try to touch my nose with my tongue, which I just about managed. We swapped a few rounds of fairly standard dares and truth questions. I was getting bored. So, thinking that it would bring the game to an end, the next time Lucy asked for a dare I jokingly said she should show me her boobs.
With barely a second's hesitation Lucy took hold of her PJ top, whipped it up over her head and off. Although she moved fast, to me it seemed to happen in slow motion. I saw the top rise up over her stomach as she raised her arms. Then I saw her pretty little tits being pulled up as she raised the bottom of her shirt and bounce down as the top came off completely. The effect was like the front of a luxury car settling on its suspension after sudden braking.
I was stunned. Of course I had seen Lucy in a swimsuit, but I had never seen her boobs before. In fact I hadn't really thought about them since they first started to appear about three years ago.
Now here they were, just a yard in front of me. I had to admit they were very nice - no, they were perfect! Not too large, but well-shaped and with the firmness of youth. The skin was milky white while the small nipples were perky and strawberry pink. I couldn't tear my eyes away from them.
To be honest, I was not very sexually experienced for a nineteen year old. There had been a couple of girlfriends and lots of kissing in the last year, but I had not got beyond a bit of fumbling under bras and brushing fingers across panties. This was as close as I had got to naked boobs and they were my sister's!
