Sister porn

"**** porn" she said bluntly "sister catches brother masturbating! this sounds familiar"

"I err…" I stammered

"Have you been having inappropriate thoughts about me little bro? How naughty. I didn't realise you've been fantasising about being caught as well. Very kinky" she said with a wink.

I was speechless and very turned on.

"So tell me little bro, how long have you been fantasising about me?" She asked

"I…well, since I first heard you having sex I guess"

"You listened to me getting fucked! You are a little pervert aren't you!" She laughed "when?"

"A couple times" I replied "first time was after a party couple of months ago"

"Tracy's party?" She asked

"Yeah I thinks so" I said

"Oh my god" she gasped "you listened to me lose my virginity! Oh no, my little brother heard me lose my virginity!" She giggled

"Are you mad?" I asked

"No, it's actually kinda hot" she said flashing me one of her naughty smiles. "So how many times after that?"

"2 or 3 I guess" I noticed her smile widen at this "I've heard you masturbating too, though"

"Oh no" she laughed and covered her face in embarrassment. I watched breathlessly as her free hand drifted down between her legs. She began to touch herself through her panties as she giggled. "So you've been in here jerking off listening to me getting fucked? That's so unfair!"

"W-what?"

"I never get to listen to you fucking" she laughed "although, I may have her you jerking off a couple times"

"Wow, really?"

"Yeah" she said smiling at me nervously "didn't hear much, just a couple of grunts, moans and the bed creaking a bit. It was enough to get me off though" she winked at me again.

"Have you been having inappropriate thoughts about me big sis?" I asked teasingly

"Lots" she grinned
