I went ahead and threw together a mostly complete guide to brother since I dont think its all been in one place before and some details are misunderstood
Before you start-
Become Bi. Get depravity up enough to go without underwear. Get to blonde intelligence for a perk and to proceed with mom
At the same time work on getting stepfather to move in. This comes into play way later. No rush
Tamara-
Get job at Shop
Talk and help her to raise relations at work
Once you can compliment her start arranging goods without panties on (where it says she watches you)
Keep doing this and talking to her until she starts taking advice from you
If it says shes not ready keep arranging goods
Talking will begin to say she needs porn, buy the porn magazine in city and gift them to her. 3 to 4 should do
Now when talking she will either invite you to her house Mon Thurs Sun or say shes not lesbian, in which case keep raising relations and arranging goods
Steal DVD in the city mall and view in her house at 19:00 Mon Thurs Sun
Eventually get option to try like in movie
Now keep visiting and going to bedroom til husband shows up, say I wont mind
Visit now at any day that isnt Mon Thurs or Sun (no more DVD needed) for threesomes
Do this until at work Tamara tells you her husband wants to have sex with you, agree.
Have a single threesome with Tamara and husband. Note that this is after you agree to have sex with him which is different than the ones before. This is needed for stuff with brother to occur.
Do not continue threesomes after this until brother is finished.
Brother-
You meet him in july at the earliest in front of your house. Raise relations with him on weekend at home or at his place during the week
On weekends at 18:00 he will eventually ask you to get Tamara to go on vacation. Agree OR beg kickback for free golden mask (requires blonde intelligence)
At work offer Tamara to go on vacation
Go on vacation with brother at 18:00 weekends. Save before asking for vacations, mom/stepdad events can mess this up. If they do go with brother after 19:00
Be alone with Tamara while on vacation.
At work discuss the rest with Tamara
Repeat vacation, brother should watch you this time
18:00 on weekend discuss what happened with brother. He gives you laser hair removal tickets
Repeat vacation, brother will touch Tamara
At work dicusss with Tamara
Repeat vacation, when sleeping option to listen should happen
At work discuss with Tamara
On weekend 18:00 discuss with brother. New scenes on vacation now
On weekdays 19:00 at brothers 'ask yourself' You need to be cute or better to pass event
Repeat vacation, event with brother and Tamara happens when sleeping.
On weekdays 19:00 at brothers talk to brother about event
Go to Tamaras house after 19:00 to talk about event
Masturbate in your room at noon on weekend for event twice
On weekdays 19:00 at brothers discuss what happened
On weekends at 8:00 lie down with brother. More vacation scenes now
Blow brother when/wherever until view ero film is an option with him on weekends. Stepdad must be living in house for this option
On weekends at 8:00 lie down with brother. Go all the way. Most scenes with him unlocked now.
You can continue Tamara/husband stuff to have new scenes at her house and to unlock her father. This leads to event with brother but thats a bit beyond the scope of this.
Note there are also scenes with brother when you are preggo
Pitfalls-
Getting Tamara divorced too early
Talking to Tamara with dirty face, she may not talk to you anymore
Vacations cant happen when raining or during winter months
