@B3AN No category other than bikini I guess which gives near 400 cards. You are looking obviously for the realistic on the beach look rather than the high heels they wear most often in the fashion shows. Not sure if you only want Crystal Clear cards.
Tatiana Coco in her Bikini's Goddess card looks a good fit for you, but I bet you have that. Not ***** flops or high heels, but seems like practical type shoes for the beach. Also it is table only with a model with big boobs. You might not like table only shows and models with big boobs. It's all very subjective if you like the models I mention.
Another I found Emily Spenser in Beyond Innocence looks good back in 2013.
Rachel Roxxx & Shay Laren together in Little Sirens, but one model only is wearing ***** flops and only medium resolution back in 2010. And only 16 mins and loads of short clips so probably not that one.
Another table only show from 2014 with Sophie Lynx & Sasha Jones, one in ***** flops, the other bare foot.
This could be exactly the one, but only standard resolution in 2014. Naomi Nevena being a Beach Tease. 👍
Maya Grand made a solo xxx in 2015 but I think the ***** flops were probably gone early in that.
Have to mention Anny Aurora in her 2015 solo xxx card. ***** flops only make a guest appearance in a few photos and not in the clips, but I feel you might like this card. It's as if she's on a very private beach.
So think I need my breakfast now, never intended to get into this so much, but it was fun.
Was working semi from memory, but I bet there are others.
Probably should be a ***** flops tag as you mention.
