Nope. No walkthrough. I purposely made this game so it doesn't need a walkthrough. There aren't any bad endings or game overs (other than a joke one in the first scene of the game). Like
@TheDevian said, just go after the girl(s) you're interested in - or have a couple different saves.
There's a decent amount of stuff that only happens if you did certain things earlier in the game though. For example, in the last version, if you don't hook up with Mrs. Sollain there's a "threesome" opportunity with Jessica and Nikki (no penetration) IF you said earlier you didn't mind if Nikki hooked up with girls AND you previously went on a date with Jessica. Or you have sex with Skylar in the hot tub IF you chose to hang out with her earlier in the day, otherwise she just gives a BJ in the hot tub. There's no wrong way to play, which means there's no right way to play either, which is why there's no walkthrough.
Maybe once the game is done, I'll make a doc that explains the different paths, variables, and choices, but I'm not sure the story really needs it.
