Okay for the last two images on Dallan NSFW unfortunately since the newest update you cannot like unlock it but if you haven't seen it yet here's what you need to do
- Become Chelsie assistant
- Earn all her “friendship points„
- Have $€× with her
- She'll ask about testing a certain device
- Obviously yes
And there you have it for Therium NSFW and non-NSFW (yes you'll get them both) you simply have to refuse him when he asks about having dinner at his place. You could've like try a bit more harder next time... just saying
