Quick list of pics and how to get them, going mainly off of memory so I apologise if these don't help - figured my first post should be a helpful one.
Pics 1-2: win and lose Skye's dice game at high lust.
Pic 3: get Hana naked and be beaten by her, just hit her with just the clothes wrecking attack and have the tougher clothes card equipped to give yourself a better chance of wrecking her outfit.
Pic 4: be beaten by Hana, pretty easy to do at the beginning due to her blocking everything.
Pic 5: own/use dildo (and anal plug), not sure if lust plays into it but buying the aphrodisiac can fix that easy.
Pic 6: photoshoot with high lust, again having the aphrodisiac helps.
Pic 7: sleeping events, don't bother with stripping her, just stroke her pussy each time for quick results.
Pics 8-15: fight grabs by bum and Hana when naked, takes a little patience due to repeats, best way to get the bum is to fight him at night where he's much, MUCH tougher.
Pics 16-18: be caught by guard in each section of museum heist, best way is to save between each section and throw the fights, then reload and get through each area straight after.
Pics 19-20: Training with Raven and Skye, just pick which one to do the licking to get each one.
Pic 21: visit Wonder Woman with high lust at night as Zoom/whatever you name him
Pic 22-23: Get high enough points in Raven minigame to unlock each scene, then visit her room as Zoom/whatever you name him to get each one via training and advanced training.
Pic 24-25: win and lose Xmas minigame for each one, win is with Raven and lose is drunken dildo play.
Pic 26: after meeting April, wear bikini and use dildo to get it.
