Her boyfriend Alex

"Lucy? Are you in…wow" Alex gasped As he took in the sight of my naked body.

"Yeah my boyfriends staying over. Just wanted to let you know" Lucy said.

I was too stunned to say anything or to cover myself. I just stood there letting Alex examine every inch of me. Alex was pretty well built with short brown hair. I had seen him st school a couple of times but had never seen him with Lucy before. Looking at him now I realised he was actually pretty hot. I guessed by the way he was staring at me, he thought I was too.

"My sisters a bit of an exhibitionist" Lucy said "she likes to walk around like this when out parents are out"

"Really?" Alex said not taking his eyes off my tits.

"Oh yeah, she's kind of a nudist" she continued "but don't tell anyone. It's a secret. You don't mind if she stays like this when your around do you?"

"No, not at all" Alex said grinning.

"Hey, don't get any ideas" my sister said "looking, no touching"

"W-wha…sure" he stammered.

I was still silent. I didn't know what to say.

"C'mon I think you've seen enough" Lucy said dragging him from my room. As he was pulled through the door I saw him cast one last glance at my nude body.

I was mortified but I actually felt really excited and I blushed as I noticed that I was a little wet too. I hope they didn't notice.
