Take this with a grain of salt, but my favorite site for h-flash games is
legendofkrystal.com/forum/ ==> creative corner ==> flash games.
Upside: best h-games from an actual game standpoint and the pron is not bad at all.
Downside: 1) most projects are in-development and not fully ready to play / occassionally bugging out
2) most (if not all) of the games are furry and/or monster... If that's not relevant to your intrests, be careful on this site.
Specific suggestions from the site:
Mario is missing (peach vs classic mario baddies)
Sakyubasu no Tatakai (succubus vs random monsters)
Legend of Twin Orbs (3 playable characters vs all mannor of baddies... humans, tents, furries)
Legend of Krystal (warning: furry main character, Krystal vs Starfox monsters)
