Numbering slightly change after updating to 22.4 due to corrections. I suggest you update your game so you can follow how to unlock the pics below:
L415-L422 = NTRS path. AskItShareIt make Matt wait one more day then tell the other colleague to try his luck. Continue the chat until Liz is in the hotel. Since Matt will wait one more day, Liz will spend time with the other colleague. At the end of the scene, selecting 🥵 will give you L423 and L424, while selecting "cum on her face" will give you L425.
L391-L393 = NTRS path. Make Matt go to Liz already in AskItShareIt. Run chat until Liz arrives at hotel. Ask Matt to "take a bit easier" then select "Deal!".
L366 - L374 = NTR-NTRS path. Make sure to sleepover with Liz after going to the park. Pics are during the train ride starting with L366. To unlock L368, select "not sure". Make her find someone else, go to the bathroom, and give panties to another man in the train to unlock the pics until L374.
L371 and L375 = NTR-NTRS path but Willpower must not be below 1%.
L331 - L339 = I got these pics on Happy-conservative path. Pics are from the Comic clip after MC arrive at Liz hotel.
