Hey guys.
Once I'm done with all the rewards, I intend to try another walkthrough in which one could get as much points as possible in the secondary stats
and have 100 in LP. Correct me if I'm mistaken in any of my assertions:
The maximum amount of LP that one could have before the D squirts (+15) is 90 LP, so you can theoretically sacrifice 5 LP for other stats. In that case, I think the choices that are the most profitable would be letting the bartender continue to peep (+5 in sharing points) and continue to massage D in the beach (+5 in exhibition, and apparently +1 in both boobs and ass points).
Other possibilities:
Ass point: Massage her ass in the shower (day 10, evening). You can also do that by continuing to massage D's ass on the beach, but you'll get an extra -4 in FP.
Exhibition: Red Dress in Day 12 (I think). You'll miss the LPs, but you get +2 in EXH. You can also flash D's boobs, but you'll only get +1 while missing the +2 through the kiss, so it's not worth it.
Sharing: If you pinch D's boobs, you get +1 in sharing, along with +2 in EXH, but you lose -2 in LP and -5 in FP.
BDSM: -2 in LP if you decide to slap her ass in the photoshooting, but +2 in BDSM. You can also do that in the office for +1 in BDSM, though you'll only lose FP (which is a worthless stat when you get past the seventh day).
Easy. Make the daughter a manipulative slut. Take this game, exactly as it was in the start. Except completely change everything about the daughter's personality. Instead of being naive to the point that that one could argue she's mentally challenged, instead she's a nymphomaniac, who developed severe daddy issues, obsessed over incest porn, fantasized about get fucked by her father for years, and then was presented with a chance to go see him. She arrives, and immediately begins the seduction, ultimately succeeding.
There. Father fucks daughter, no fatherly manipulation necessary.
That, or daughter is simply in love with her father, but is uncomfortable about showing it in fear of being disowned by him. Cue the father picks up on her insecurities and tries to reassures her. The corruption meter would instead be a "confidence" meter.
