Not quite

I turned and saw my sister standing in the bathroom doorway. She was standing in nothing but one of her pink towels wrapped around her. It was fairly small and didn't cover much. Her boobs were almost bursting out the top, if she leaned forward slightly I'm sure they'd be out in the open. The bottom of her towel rested high up her thighs, only and inch or two below her most private areas. Even covered by the towel she was still a sight to see.

It took a moment before she noticed me walking towards me.

She eyed me up and down. "So, you do have some shame" she said motioning to my boxers.

"I just didn't want to make you blush" I replied

"Trust me" she said "you were the only one blushing" she took a few steps towards me and rested against the wall. She relaxed her hands by her side, her towel was now at risk of coming free. I imagine it fluttering down to her feet revealing her amazing body.

"Where'd you get the towel" I asked "I couldn't find any"

"Oh, so you thought I wouldn't have one? I guess it wasn't a coincidence that we walked out at the same time then, huh"

Dammit, caught out again, I thought.

Becky just smiled, she knew she was right. "Well, it looks like you're enjoying the view anyway"

I looked down a noticed that my boxers had started to tent.

"Wow, if I'd known seeing me like this turned you on, I might have thought twice about walking round in my underwear. Actually I might have done more" she smiled "do you get this excited around all the girls?" She asked as the tent got bigger.

"Well, not really…" I said

"So it's just me, huh" she teased "have you been with many girls?"

"Not really, I've made out with some but I've never really gone that far"

"You ever seen a girl naked?"

"On the computer, yeah"

"That doesn't count, dumbass. You ever seen a real girl without her clothes on?" She asked.

"No" I answered honestly.

She looked at me for a moment in silence before responding. "Would you like to?"
