Get in the back seat of the car.”She nodded her head and slid into the backseat. I followed her and closed the door behind me. I tugged my skirt up ...ut of the way, I was panty-less as always. I turned to lean against the door, and she got on her knees and buried her face in my pussy. I held her head against me as her tongue worked its magic. I nearly lifted off the seat when several of her fingers slipped into my pussy.“Oh fuck! Yes! I want all the fingers!” I demanded as I tried to stay aware. Then she did something I thought she would never do, especially this being my 15 year old sister. She sat down on the toilet and spread her legs wide open!!! She then pointed at me through the mirror, then pointed at her own crotch. Then she started rubbing herself. I just couldnt take it any more. I pointed to my own crotch, the whole time her watching me stare at her in amazement from the couch while she masturbated on the toilet from the view of the mirror. She nodded her head in approval,. The bartender asked her what she’d have, and she briefly considered her usual rum and pineapple juice before answering, ‘What the hell, give me a Long Island iced tea.’ What might have been a discreet chuckle came from the man at the end of the bar, and she turned to look at him. He didn’t smile, but his eyes were clearly amused, and he raised an eyebrow at her while he talked on the phone. Sky figured two could play this game, so she took one long sip of her drink, then two, and raised her. And I could tell she liked it too. I could smell her aroma, even above the blankets. It smelled oh so sweet and intoxicating. She turned red when she saw my nostrils flare. I couldn’t control myself after that; I had to show her just how much I love her. Under the warm covers, I quickly put my body over hers again, making her jump just slightly. I noticed she was breathing faster. I stared into her deep, green eyes as I ground my member on top of her nicely trimmed mound. It took my breath.
