Having a hot-bodied, partying older sister had its benefits for me. Mostly, when she'd come home from an evening of drinking and not able to find her keys. My sister "D" would tap on my bedroom window to let her in. At first, I did only that; let her in the house. Maybe chatted a bit but otherwise went back to bed. After a few instances, though, and noticing how disheveled, out of sorts, and flirty she was (D regularly thanked me with a hug and quick lip kiss), I began trying different advances on her.

D came home in the early morning hours, tapping on my window to let her in. Doing so, I noticed her slutty mode of dress and inebrieated state would easily allow my hands to roam. Short skirt, low-cut tank top, lot of skin exhibited, long nails done jet red, and just an arousing presentation. Following her down the hallway with my arm wrapped around her to hold her up, D thanked me in her usual manner, hugging and kissing me. I pressed her against the hallway wall and proceeded to kiss and basically maul her, going up her skirt and working her thongs down.

"Mmmph..Waaitwhee& quot; she muttered as I flipped the tank top above her tits. I was on a mission that night. Knew having her this drunk and whatever else was rare, and I needed to take full advantage.

With no one else in the house but us, I had a free pass. Continuing to have at her, with her under the influence approval (she began stroking me in response to my essentially stripping her), I walked us into my bedroom and placed D onto the bed, closing and locking the door behind me.

I'd make fucking her a regular thing any and all times I'd be called upon to let her drunken ass inside the house. Thing is, I know there were a few times her keys were either on top of her purse or in her hand. She just liked having me pay attention to her.

True story.
