Am I Weird For This?

So years back my uncle was dating his future second wife and I always thought two of her daughters were attractive, one was a few years younger than me the other a few years older. We were all teenagers at the time. I wasn't going to mention the first part of this but I'll throw it in there because there's really no reason not too.

So the younger daughter was hanging out with my friend and I while her mom was out on a date with my uncle. The conversation took a turn where she was telling some pretty unbelievable stories about her past so we called her out on it. We said we didn't believe she did any of it. She countered with something along the lines of saying to prove how rebellious she was that she'd flash us. We again called her out on it, so she lifted her shirt showing us her small, but very nice breasts. I'm not the type that needs huge ones to like them, I can even get turned on by flat chests. We pressed for her to do it again but unfortunately, she never did.

Fast forward and my uncle married their mom. They would all go on big family camping trips with us and while my attraction to the younger one wore off as we aged (she just never matured and was always in trouble), the attraction for the older one stayed strong. One night we all went for a walk and she got pretty flirty with me and it was killing me that nothing could ever happen.

Fast forward to earlier this week, my uncle and their mom have divorced I think 5 years ago. I stumbled on the older daughters nudes online by chance and couldn't believe how turned on I was! In fact I even saved them to my phone. It was a whole collection of pics and videos of her giving demonstrations on how she uses her favorite sex toys. I haven't said anything as we barely talk anymore.
