Every image file is titled after the artist's name, and is also organized alphabetically (cept the first 3, they have different artist but they deserve to be batched together!)
Doesn't have any male focus, femboy, futa, furry, anthro, ai generated stuff but theres a lot if you want to look for it.
There are also some good stuff I found that is more dildo riding and less dildo hiding, but I avoided putting that in here too... sometimes...

If anybody else tryna look for more:

While I'm at it here are my notable faves:
1-3 loved that 2 different artist continued the challenge
37-40 seriously seductive secret
67-72 dildo mask was the first step
89-91 one of my absolute favorite artist/authors in art and story
130-131 anal god artist
157-162 i fckin love this bratty character and artist
169-171 composure fail
186-189 pretty sure mamimi started this dildo collection + sitting power combo
195-197 animated by the great mike inel
239 "biggest" wtf
282 one of the most referenced pages ever! (from QUEENS GAME)
288-293 3 girls take turns

im OBSESSED with this stuff, the best ones are the ones with amazing facial expressions, contrast of innocence/eroticism, comedic narrative, exciting stealthiness, and/or unrealistically obscene insertions
