Big Sister's Big Ass #1 (The Check-Up)

... clothes pile, never figuring out how to get rid of the musky smell I also coated them in. A few seconds later, Emma strutted in and quickly got to work, finding out I weigh 135 lbs. and am 6"2'. "Jesus, you've grown a lot." Emma remarked. "Ok," Emma said "Now sit back down on the bed and I'll check out your mouth". "So, why aren't you wearing one of those sexy nurse uniforms" I asked, as she grabbed one of those big popsicle sticks from a pile on the top of her dresser. She gave me a sexy smile, not at all perturbed by the question. "Well - sadly - your expectations for what a nurse looks like comes from Halloween parties and porn." Emma told me, walking from her dresser to the bed and putting one hand on her hip, "Besides, you wanna see your sister in one of those?". "Yes" I quickly answered, acting like she was the one who sounded crazy. Emma went into nurse mode for a few seconds, telling me to say "Ah" as she stuck the big popsicle stick on my tongue, then came back. "Even around your sister you're an uncontrollably horny, teenage boy?" she asked, while looking into depths of my mouth.

She looked the sexiest she has ever looked to me - not an easy thing to do - as she stood with her back to me, hair in a ponytail, concentrating hard on writing the right stuff down on the right parts of the paper. Unable to control my urges, I jumped up off the bed and stepped towards her, my heart beating in my ears. I lost a bit of my confidence after a few steps, but quickly regained it as her curvy butt drew me to her like a magnet. Emma kept her focus fully on the papers, even as I was just a foot away from her and smelling the fruity scent in her hair. Then, moving my arms around her and resting my hands on the front edge of her dresser, I lowered my lips to her neck, peppering it in gentle kisses, and animalistically pushed my hips into her, feeling her amazing ass squish against my hard cock. "HEY, wh-what are you doing?!" Emma protested, while unsuccessfully trying to break free from my arms. I knew it would take a little seduction to get her to fuck her very own, little brother, and I also knew I had the skills to do it, with quite a bit of experience from high school girls. "I don't know" I replied earnestly, "I can't ...
