It's this one.
In all my playthroughs through the three paths, I get nothing from Laura and the text with the picture is from Nathan. From what I'm gathering, the lingerie choice (either submissive or slutty) is a second major choice as well, so the MC has three paths (submissive, balanced or dominant) and Laura has two options down each path (submissive or slutty). Perhaps that lingerie choice has something to do with it.
Wtf i have never gotten this picture and ive done like 5 playthroughs and in 1 i made her super slutty and myself sub. Man i really need to look back for a few pictures. Which chapter is the swimsuit choice? im gonna test it out cause im most of my saves the last photo from nathan is the after shower blowjob after fucking her before. I never gotten that raw or the xray raw picture so im questioning if going full slutty or full sub is the way to go.
EDIT: Yeah no it has to be with more decisions. Im on the sub path and choose the red and the white one and didnt get the raw pictures that Laura went to fuck Nathan. The last interaction they had was after the photo session with the blowjob and raw fuck so maybe its a random thing?
EDIT 2: I think its the escapades choice where Laura ask if you would enjoy if she talked about her escapades which means you get your info from Nathan instead of Laura i think. I want to test it out but i dont know which chapter it is.
EDIT3: can you show the system choices you made? maybe you have something different then mine with that photo.
EDIT 4: i think some photos are bugged: there are 3 raw nathan laura photos(1 x ray and 2 normal) that happen after the photo session but they dont happen in the Sub route which seems weird cause that means that Laura is more 'solo decision not tell MC' in the Dom and Balanced route then in the Sub route where we literally give her permission to fuck Nathan when she wants.
EDIT 5: its a random interlude which seems weird cause those pics and one extra should be deffo on the sub path and not on the dom or balanced paths
