Memories of my sister’s butt

I don’t remember exactly how it first started, but when we were growing up my sister (let’s call her Emily) and I would tease each other by showing off our butts. I think the first time might have been a game of truth or dare, but I really can’t recall for sure. What I do know is that for a few years whenever I was feeling horny, I would ask Emily to play a game of you-show-me-yours and I’ll-show-you-mine, and more often than not she’d agree. We kept our genitals hidden, but somehow decided that showing our bums was fine since we both had one of those. So our games of show-and-tell consisted of one of us sitting on the floor, while the other stood in front with the back of their pants and underwear pulled down. Whoever was standing would hold their butt cheeks apart with their hands so the sibling on the ground could look at their butthole.

Around this time my parents got me a laptop, and I used to play Newground games on it in my room when I wasn’t using it for school. Emily was always really interested in what I was playing, and like lots of little sisters she wanted to be included. One day I was feeling horny and told her she could try a game on my laptop if she showed me her butt while she was playing. By this point exposing our rear ends for each other was nothing new, so she agreed to the proposal without any hesitation. We put the laptop on my bed and Emily laid down in front of the screen, sticking her backside in the air for me. Then I sat behind her and pulled her pajamas and undies down so her anus was peeking out over the waistband. It was mesmerizing to look at, it was light brown and adorably puckered.

At some point we decided to try smelling each other’s butt. I don’t remember whose idea it was, but that first time is still a very fond and vivid memory for me to this day. It started like a “normal” game of show-and-tell, me sitting on the floor and my sister standing a few feet in front of me showing off her anus. “My butt’s gonna kill you!” she joked, then she shuffled backwards and stuck her ass in my face. She spread her cheeks and positioned her butthole just an inch in front of my nose. I took a curious sniff and found it to be an incredible turn-on. It was sweaty and stinky, but there was also something so warm and intimate about it that I just couldn’t get enough. I kept sniffing her butt for a bit, and Emily giggled the entire time. Then we changed roles so she could smell mine, but she wasn’t nearly as into it as I was. She laughed and said “eww”, then backed away holding her nose.

For me it was incredible though. After that my sister let me sniff her butt any time she was on my laptop, which was often several times a week. She would lie down on her stomach and let me use her naked bum like a pillow, which let me keep my nose close to her anus while she played. It was amazing, and I lost track of all the times I secretly came in my pants from the sight and smell of her butthole so close-up. One thing I do regret though is that I almost never physically touched it. At the time I remember being afraid of germs, but obviously looking back I just think how much more fun it could have been… if only I could go back in time, *sigh*. Anyway, it’s a really great memory, so I guess I shouldn’t be complaining. :)

We kept that going for about a year and a half before we started growing up and realizing how weird it was. That’s still plenty of time for memories of our “butt-lives” together though, so maybe I’ll write about some of the other moments at some point.
