Take this upstairs

"Don't act like you didn't enjoy it" I replied

"Maybe a little" she gave me a naughty smile as she lay back in the armchair "I have to admit I was a little disappointed when you put your boxers on"

I decided to see how far I could take this. "If you'd prefer I could take them off"

She grinned but stayed silent for a few moments. She turned her attention to the TV still playing in the background "there really isn't anything good on, is there. You wanna head up to your room? We can keep talking and it'll be a bit more comfortable, bit more cozy" she winked.

"Sure, why not" I said

We switched off the TV and got out our seats. We headed for the stairs. She walked in front of me and I had my eyes glued to her ass as she swung her hips sexily. Once we reached the stairs her hips were at eye level and it was impossible not to look.

"You're not starring at my ass are you?" Becky asked over her shoulder.

"W-what? Of course not" I lied.

"Yeah right" she laughed.

We reached the top of the stairs and headed for my room. My sister pushed open the door and jumped straight on my bed and lay sprawled out across it.

"Get off" I said "it's my room I get the bed"

"Not a chance, I got it first" she said sticking her tongue out at me. "If you really want the bed I can always leave"

Reluctantly, I gave in and say down on my couch. She smiled to herself, knowing she'd won.

"So what do you want to do" I asked.

She turned her scantily clad body towards me. "I've got a few ideas" she grinned.
