*****
The next morning I woke up and stretched, then immediately sprang to attention when my hand brushed my older sister's ass and the memories of the past two days came rushing back: the moment of arousal when Julia held the cup for me in the car; the seemingly infinite minute when she pissed from the car on the side of the road, her asshole holding my attention; finally taking the plunge when she sucked the last few drops of piss from my cock by the lake, following it with a mind-blowing blowjob.
There had been no turning back after that, and I didn't regret any of it. After we'd gotten back to the cabin, we'd basically fucked like rabbits the rest of the night before passing out together in bed.
I slid down the bed a little and put a hand on each of Julia's round buttocks and pulled them apart, cock twitching as I revealed her anus. I dove right in and buried my tongue as deep as I could, taking in a deep breath as I did. She smelled- and tasted- absolutely divine. It was a heavenly mix of salty sweat and musk. I dug my nails into her butt and shoved my tongue in further, moving it in and out and tongue-fucking her ass.
She awoke with a groan, slowly stretching her legs and pushing her hips up off of the bed. "Goddamnit, Jason, this is the best way to wake up. Oooh, yeah, babe, lick my asshole." I pulled back a moment, placing the tip of my tongue just at the bottom of her pucker, then gently licking upward over it, smiling as she crooned and her little hole tightened up for a moment, "winking" at me. I passed over it, running my tongue the rest of the way up her ass crack, which I still had spread wide with my hands.
"Spread your ass for me, sis." I said to her. She complied and grabbed a hold of her butt with both hands, pulling the pale cheeks apart. "I love how that looks, sis." "You're a dirty little boy, Jay, sticking your tongue in your big sister's butthole." God, my 18-year-old mind could never have conceived of such a situation, yet here it was.
I placed my tongue in one of her dimples, dragged it across her skin to the other, then back down to the top of her ass, before running it slowly and ever so lightly down. When I got to her little hole, I ran my tongue around it, feeling the smooth skin of her anus crinkle and pucker. "Ooh, you're such a tease!" Julia said. I smiled to myself before placing my hands under her hips and pulling her back hard, penetrating her sphincter and spreading it with my tongue.
"Fuck, Jay, just take me. Put that huge dick of yours in your big sister." Well shit, who can turn down a request like that? Not this guy. With my hands still under her hips, I pulled her back and up onto her knees, causing her bright pink pussy lips to spread. Julia moved her hands so she could prop herself up, but I gave her ass a playful smack. "Uh-uh. I want something yummy to look at while I plow you."
