The diary can be used to rename the girls accordingly but this guide will show how to recognize these traits without it. You'll need to keep track of them and the others some other way though.
Start
* Get naked right away
* Walk around and expose yourself to everyone in the party
* Do not talk to any of random girls and learn their names - needed for the first achievement
* Keep a watch on the women's reactions and Love meter as they see you exposed:
** Rebounding girls will be have an Interested/Lust Love score
** Slutty girls will make comments about your penis ('nice hog') or references to sex ('don't threaten me with a good time')
** Nudists will comment about 'it's time you joined the party' or 'flaunt it'
** Ignore any other comments - they don't affect either the Friendship or Love meters
** Some women will only reveal themselves as Slutty when their Love meter is Interested or more
Achievement - Strangers in the Night
* Collect the following objects: all six phones, handbag, pills, cold coffee, marijuana, beer, soda, plastic cup, star bombs and tequilla bottle
** You may also need the rest of the alcohol stored in the cabinet (see Talking To Your Hostess section)
** Heat the cold coffee in the microwave and raise the house temperature in the thermostat
* Go to a Rebounding girl and give her one of the phones
** If she doesn't want any of the phones, try the handbag, pills or hot coffee
** If she refuses all, first give the soda to the girl; if it's also negative, check with the alcohol
** If she is anti-alcohol (which will result in a loss of Friendship/Love), roll and light up a joint and share it with her
* After she accepts the object or the alcohol/soda/joint, ask if there's a reward and propose the hot tub
** She'll accept the tub, unless her Exhibitionism level is negative or she's Jealous
** If she refuses, either try with another Interested/Lust girl, or you'll need to give her another alcohol/soda/joint and propose a different house location
* Go to the hot tub and wait for her to arrive
* Throw a star bomb into the tub
* Give her another drink/joint
** After she accepts, ask her if she wants to have some fun and choose handjob
** If she's also Slutty you can go for a blowjob
** Enjoy your reward and the achievement
Meeting Everyone
* In the kitchen, take and wear the sunglasses
* Go to each random girl and talk to her
* Finish conversation immediately 'I'll talk to you later'
* Talk to the girl again
* She'll make a comment about your sunglasses - only happens one time so keep track
* If she says 'are you famous' the girl is Easy Going and will always accept any pick up lines from you
** Cheesy Pick Up Lines always raise the Love meter (but can't go past Lust) and can be used 5 times (have a cool down timer), so you won't need to use any alcohol with Easy Going girls to get their attention or mend fences
Talking To Your Hostess
* Ask about info about the girls, drinks, music and food (last one only appears after one of the guests says she didn't had dinner)
* Complete her three quests (find mysterious key, mp3 player and feed everyone)
* Once you complete all tasks your hostess will ask you to take pictures of everyone
** If she asks for sexy pics, then you'll need some skin showing, just take pics while being intimate with the girls
** If she asks for social media pics, then take pics of everyone right away - when you start having sex, any girl with a high Exhibitionist value will remain naked/half-naked for the rest of the party after she undresses, preventing you from getting 'decent' pics unless you get her mad at you
** Lowering the house temperature will cause the girls to dress after sex
Achievement - Papparazo
* If the hostess asks for non-descript or sexy pics, then you can complete this achievement by taking photographs of everyone without some of their clothes
** A quick way is to invite three girls to the hot tub and use a star bomb, then everyone inside will agree to your suggestions to strip naked and you can photograph them
* If she asks for social media pics, then you'll fail the hostess's quest
Complete Each Girl's Quest(s)
* Go to each girl and complete their quest(s) that involve phones, handbag, pills, dinner or warming up
* Before giving any drinks or joints to them, find the girl who wants dinner and order pizza for everyone
** This will reduce the alcohol level of everyone in the party so if you were already working to get someone drunk (required for some girls to have sex), it will reset your efforts
** For the already drunky it will help prevent them from passing out from too much booze
* After you complete all their tasks, they'll start accepting fun offers from you, if the right conditions are met
Love Is In The Air
* Go each girl raise her Love meter to Interested/Lust
** Completing their individual quest raises the Love meter by +1 for each task
** Completing the hostess' pics of everyone quest raises the Love meter by +1
** Giving the flower to any girl gives +3 Love
** Easy Going girls (check Meeting Everyone section) only require that you periodically use a pick-up line with her (raises Love by +1), when she's alone (otherwise jealous girls might overhear you and they won't be happy)
* Alcohol immediately raises the Love meter by +2
** Wine is the scarcest of all the alcohol since there's only three bottles, so before giving any of them make sure that the girl doesn't like something else or you'll risk running out
** Rum should be used sparingly at the beginning because it requires Soda to mix and you'll need the Sodas for the no alcohol/drugs girls
* If a girl is already drunk or wasted, give her beers instead of hard liquor, otherwise she might pass out and became unavailable for the rest of the party
** Giving away a joint only raises 1, but sharing it raises the meter by +2
** If one of the stoner girls gets paranoid, giving her the sunglasses raises Love by +1
** If one of the stoner girls gets hungry, giving her individual food items raises Love by +1
* Giving a soda only raises +1
* Completing a dance with the girl raises the meter by 1
** Girls will only dance if Love and Friendship > 0 and if they're not Jealous
** If she's Easy Going, you can safely choose the 'humping dog' reply to raise the Love meter by an additional +1
* Girls will publicly strip depending on a lot of factors: their Shy, Exhibitionism, Slutty, Love and Drunk levels
* If she stripped during dancing, complementing the striptease raises the meter by 1
** If a girl does a public full strip tease, the girl is Adventurous
* In the hot tub, choosing 'I'm enjoying the view' gives a +1 Love raise
** This can be used with Easy Going girls or the other girls Love level is > 4
** Also, using a star bomb in the hot tub raises Alcohol by +1
* Publicly or privately groping a girl gives +1 Love, if she likes it
** This only works on non-Shy girls (Shy level = -50 or -100)
** If they're not non-Shy enough (-100), then they'll need to be drunk (level > 6) and their Love meter to be > 6 (if Slutty then only > 4)
** Removing her clothes afterwards also gives +1 Love
* When the Love meter is >7, go to the girl, expose yourself and start masturbating
* If the girl asks you if she can watch, then she's a Voyeur
** If you reply 'Be my guest', then she'll start masturbating as well and her Love meter will get a +2 increase
* If she's both Slutty and drunk (level > 6) then she'll offer you help
** If you accept the help, then she'll give you a blowjob, depending on the situation and her Exhibitionism/Shy values
** If you refuse the help and she starts masturbating then not only she's a Voyeur but she's also Adventurous
Achievement - Premie
* Invite a Slutty girl with an Interested/Lust Love level to a private place and start making out with her
* Grope her breasts and ass when the option appears, then remove her clothes while she does the same to you
* When both of you are naked, keep kissing and groping her but don't have sex
* Wait until your orgasm meter gets filled
Achievement - Your Private Dancer
* This achievement requires a private dance given by a girl whose shy level is 0 or more, so these girls will only accept to do it if they're alone with you
** Slutty girls require Love > 5, non-Slutty Love >6 to perform the dance, and not being Jealous (0 level or less)
* Complementing her after she finishes the private dance gives +1 Love
Achievement - Audience Appreciation
* Invite both an Adventurous and a Voyeur girls to the same house location
** Start making out/etc. with the Adventurous girl and let the Voyeur watch
* If there's no Adventurous girls, invite an Nudist instead (or someone non-Shy)
** If the girl still keeps wanting to do it in private, tell the Voyeur to go anywhere in the house, then immediately tell her to go to a 2nd location
** Go to the 2nd location with the girl, start having sex, and the Voyeur will later walk in both of you after she went to the 1st location
* If there's no Voyeur girls, check the next achievement for a solution
Achievement - The Old Switcheroo
* Invite to the hot tub two or three girls with high Love meters (Lust or more)
* Once they're all inside, sit down and throw a starbomb into the tub
** The star bomb will temporarily turn them the girls into Easy Going, Open-Minded and Adventurous while they're inside the hot tub
* Ask one of the girls for a handjob/blowjob/etc.
* Wait until the other girls react - either invite them to join you or allow them to watch
* When everyone else is busy with themselves, talk to them and ask if they want to switch
* This will also give you the Audience Appreciation achievement if you haven't gotten it
Achievement - Spectator Sport
* This is the hardest to get because it has several requirements for the Girl to Girl action to take place
* Both girls need to be at least Open-Minded, or Voyeur
** A safe way to identify them is to have sex with them and notice if they comment at the end "the other girls would be sooo jealous"
** A riskier way to identify Open-Minded girls is having Interested girls watch while saying a pick line to an Easy Going girl. If they don't react negatively, they're either Open-Minded or Voyeurs
* Both girls need to like Women
** When asking for blowjobs/sex, notice if they mention it's their first time with guys or dudes
* One of them needs to be Adventurous to start having sex in front of the other
** Or you can also use the technique previously described to get the other girl walk into both of you having sex
* When you start having sex, the second girl will ask to watch or you'll be given the option to invite her to join you
* After she starts masturbing ask her if she needs any help, and then propose your partner as a better helper
* When both of them accept and start having cunnilingus, expose your penis and start masturbating while watching the action
* You can also get the The Old Switcheroo achievement if you instead join the threesome and switch between the girls
Achievement - Hard Mode
* This requires you to be intimate with all girls while not using the diary or the keychain
* If you only use the three restrooms or the washing room to have sex you're safe from getting caught since the girls never wonder into those locations by themselves
* If you need to use the hot tub or some other place, you can speed up the orgasm meter by groping the girls boobs during sex (doesn't work on doggiestyle or against the wall positions)
* As long as you avoid getting caught, you're safe from the other girls getting mad at you or even trying to fight you
* To have sex with your hostess, follow her instructions after you first attempt to get intimate with her
