How do you get the other portraits? That's one of the few I managed to get accidentally lol
Portraits:
Arugula- buy alcohol, drink it, then suck his dick (basically tutorial), increase libido to 90%, buy alcohol, drink it, and return to office to unlock scene
Zabaione - Unlock ice cream parlor (you do this by successfully suck dick in the bathroom), Ask for free samples twice to see first scene, then once your libido is high (70% - 90%) ask for a free sample and unlock the scene.
Mocha- (it is in the comment above)
Slushie - To unlock successfully suck dick in the bathroom (I have needed to do it 4 times to get him to appear), buy whiskey at liquor store, go to parking lot and give him whiskey this will show the first scene, increase libido to 70%-90% range, buy whiskey again, go to parking lot and find slushie to unlock scene
Morel - To unlock YOU MUST HAVE DONE THE SLUSHIE PORTRAIT UNLOCK SCENE this gives you access to the movie theater. Before you go there go to the bathroom and suck dick. You will hear a rumor about a pervert that goes to near empty movies. Now you can visit the foreign film and get the first scene. Increase libido to 70% - 90%, buy and drink whiskey and return to the foreign movie to get unlock scene.
