Okay so by pure luck I managed to do the Tamara's dad (Valentin) questline, here's a general guide:
-He appears on weekends after Tamara gets divorced, in her house. He's at 10am in the bathroom then at 1-4am in the hall, then after 9pm in his bedroom on saturday and sunday
- You need to catch him in the bathroom a lot of times, and go on chatroullette on your laptop until you get an event
- Talk to Tamara, go on chatroulette again, meet him in the hall during the day, talk about it, then you can fuck him, he has events in all 3 places he shows up.
- at some point Tamara's phone will appear in her bedroom around 10pm. You impersonate Tamara and send him nudes until he gets angry
- Talk to him, talk to Tamara again, buy ambien and lots of female viagra in the city
- You can then send more nudes from Tamara's phone, do it until the phone stops showing up. He will send you his dick picture.
-Show dick pic to Tamara in the shop, talk to her again in the shop on the next day, give her ambien
-At 11pm in Tamara's bedroom there will be an event to sneak to his room, do it twice then talk to her she will refuse to do it more.
-Afternoon in the kitchen you can now spike Tamara's drink with female viagra, then you can go with him to the dads bedroom again, do it like six times, have sex with her after
-At some point the dad will join. All threesome events are unlocked now, you can also still keep giving her viagra and sneaking in at night.
There is a side quest where you can make Tamara's dad and your stepfather talk to each other and then at 3pm in the weekend you can talk to your stepfather in the hall and go for an event with you, Tamara's dad and Tamara, one is camping one is movie. There are sex scenes related to these events in the files but I have not figured out how to trigger them yet, they don't show up after the Tamara route is complete.
