I know this is pretty niche, but can anyone send me the way to anything like this????

There was one bodybuilder / Fitness type girl that Lenny made some pie videos with...I think under his "Excessive Mess" series....she was a brunette...maybe Latina...moderately long, dark hair. Nice body.

Alexis was her name, but she also did some pink slime sex in a paddling pool with her bodybuilder boyfriend. (I think he was named Tony).
I think she sold it on Clips 4 Sale

As I recall, she genuinely seemed to enjoy getting messy

I think this is the pink slime pool scene you're referring to

Yes, that was it. It is interesting to see that she did other messy things, too. I wasn't aware of any of the other content that is on her clips4sale

Check out messy_dora on instagram (she also has a patreon)

I thought Slapstick Stuff had a few female fitness models. Also, alexisrain has a few scenes and she seems pretty muscly.

Absolutely, and while none of them are really "bodybuilders," they're definitely on the same level as some of the other names that have been tossed around here.... so maybe the OP was just looking for "women in shape"?

SS247 Lyndsay is probably your best bet (she was also in SS135 and earlier volumes, albeit less buff). SS235 Taylor, SS202/216 Jess, and the MILP are all really solid too.
