My 30 year old sister Sarah's asshole had a faint odor that smelled of banana scented lotion and musk from daily sweating. The scent of her rectum made my cock even harder. I pressed my nose into the opening of her asshole. She moaned and grunted softly as she pushed her butt against my face. Her sweet butt cheeks rested softly against my face. I was so hard I could have busted a nut all over the floor without even touching myself.
I began running my tongue up and down the sphincter of her anus. The taste matched her aforementioned odor. I even licked her ass crack. This is what I had wanted for so long: my older sister Sarah's ass. I wanted to devour it; I wanted to feast on it. I wanted to literally fuck the shit out of her.
I placed the head of my cock against the entrance of her asshole, barely tipping the hole that I had just sniffed and licked like a lollipop. She reached behind her with her right hand, as she was lying on her left side, and spread her right butt cheek outwards, allowing her beautiful asshole to spread apart for my hungry cock. I slowly pushed in. The base of my cock was now inside her; she let out a soft "coo" of a moan as she gently backed her ass up against me in small increments.
Sarah's asshole was warm and soothing; I just wanted to fall asleep bundled up with her, with my cock inside her anus.
