Introduction

Introduction to the H Interface, a brief explanation that points out the function of each button in-game

When doing H for the first time with a girl, you are given only the caress option. After the girl's first cum, you can later ask the girl to service yourself. Lastly, when you and the girl are done cumming, you can begin insertion into her. Remember: You cannot leave the H session until you cum inside the girl together.

Caress Mode

In this mode, you can make the girl cum by interacting with their lips, chest/breast, pussy, butt, anal (unselectable on refuse anal). You can either click repeatedly or hold the left mouse button then shake it around to caress the girl. Using the mouse scroll, you can change what type of caressing you are going to do ranging from using your hands, pinching by hands, vibrator, and your tongue. At a time, you can have a max of 3 different parts caressed as you have 2 hands and a tongue.

In the new update, some girls have a limit marked with X in their first time, so you cannot go intensely on them.

Service Mode

In this mode, you are serviced by the girl, you can set the girl auto by selecting the button just above the speed box so she does what she likes to please you. You can use mouse scroll to set up the speed of the service. While being serviced, you can also interact with the girl like you did in Caress Mode. In some positions, you can choose between cumming inside her or outside. It is not possible to make her cum in this mode as the bar will be maxed at the 1st cumming threshold.

Insertion/Piston Mode

In this mode, you begin insertion into her or as the game's called by piston. Before beginning insertion, you can choose to use condom or go raw. As for types of insertion, the pink button is to ask the girl first while the blue button to insert without asking, the other pink and blue buttons if present, is to insert into her anal. Take note, you cannot force insertion using the blue button*. You can set it to auto with middle mouse button to make the bar moves constant in speed, this will allow you to caress her just like in caress mode but also will make the girl cum earlier than you if maxed out. Like in Service mode, you can cum inside or outside the girl. Cumming inside while the girl went past the 1st cumming threshold will initiate cumming together. You will not cum together if you choose to do it outside.

*This game is fully on Love mode, rather than forced or bdsm play.

H stats

H stats are the 8 H-parts including the change in Love and Horniness as shown in the image below,

To increase related-H stats as explained on the handy table below:

H Parts	Things to do to raise the stat
Chest	Use hands to massage her breast/s during any mode
Nipples	Use pinching hands/tongue/vibrator on her breast during any mode
Pussy	Use hands/inserting fingers/tongue on her pussy during any mode
Pussy Piston	Do insertion into her pussy, cumming inside together increases this part faster during piston mode
Butt	Use hands/vibrator to massage her butt
Anal	Use hands/inserting fingers/tongue/anal vibrator on her anal during any mode
Anal Piston	Do insertion into her anal, cumming inside together increases this part faster during piston mode
Service	Do any service positions (e.g. hand jobs, fellatio, paizuri)

useful tips: you can grind her parts even if the girl's excitement is locked (e.g in the service mode). This allows you to max out her stats in just one go except pussy-piston and anal-piston which requires you to cum inside.

Anal Refusal Guide

A girl who refuses anal at first can be developed to accept it. Attempting to touch her anus while in a Caress position will trigger her rejection, but will also give a tiny amount of exp in the area. This is enough to permit Anal Teasing and increase area exp next H encounter with her. Attempting Anal Piston after this will place a random check between 100 and the girl's anal area exp -- 100% exp will guarantee success. Note that this check is done once per session, so gaining permission during one scene doesn't automatically grant it the next.

Risky Days / Pregnancy

The Risky or Safe indicator is located just below the girl's picture when doing H.

Red = Risky Days

Yellow = Safe Days

Risky and safe days alternately lasts for 3-days game time. (weekends not counted) There is no pregnancy in Koikatsu, it is just limited to a change of dialogue when doing H. This is meant that this game is for casual H players, to enjoy the game to its fullest.

A girl who refuses vaginal insertion without a condom can come to accept it. When in Lewd state, a girl will accept 'raw' insertion as long as it's not a risky day. After permitting raw insertion 5 times, she will also allow it in Experienced state. Teachers will never permit raw insertion. As of 7/27 update, girls who don't refuse without condom use will never insist on it.

Peeping and Yuri

will be updated asap with images, maybe transformed into a table :)

Toilet Peeping

By following or witnessing a girl who went into toilet, you can initiate peeping by interacting with the toilet's door marked by a love heart symbol.

Shower Peeping

By following or witnessing a girl who went into shower, you can initiate peeping by interacting with the shower's door marked by a love heart symbol.

Masturbation Peeping

By following or witnessing a girl who went into a room, with the condition that the girl has a maxed Horniness (by 100), you can initiate peeping by interacting with the girl in the room. Use crouch button (default: CTRL) if you are not a lover to keep the girl from running away embarrassed.

Yuri Peeping

By following or witnessing girls who went into a room, with the condition that the girl has a maxed Horniness (by 100) and one of them has I Like Girls Trait, you can initiate peeping by interacting with the girls in the room. Use crouch button (default: CTRL) if you are not a lover to keep the girl from running away embarrassed.

Sleeping in The Infirmary

Successfully sleeping in the infirmary bed will take around 1/10 of the current school period. However, there's a unknown random chance to trigger H scene if you have a lover and with the minimum condition to have 50% horniness status.

When the nurse teacher is present at the room, a guaranteed 100% sneak attack will occur.

Advanced H Guide

H ending results

H ending is where the player is given certain dialogue when finished doing H with the girl. It will give an effect on both the love rating and H rating based on the player's performance. To achieve certain result, the player must fulfill the condition.

Condition	Dialogue	Effect
Virginity Taken_[1]	Virgin H	+20 Favor -10 H
Cum 0, girl in Lewd state	Bad H	-10 Favor -10-20 H
Cum 0, non-Lewd	Bad H	-20 Favor
Only Girl Cum	Horny Girl H	-10 H
Accept H Invite, Cum 1+_[2]	Grateful H	+20 Favor -10-20 H
Public H, Cum 0 or H < 80_[3]	Humiliated H	-1-5 Favor
Public H_[3], otherwise	Exhibitionist H	+5-10 Favor
Cum 3+ times[3]	Exhausted H	+5-10 Favor
Cum 1-2 times	Satisfied H	+5-20 Favor -1-20 H _[4]
Girlfriend, Favor > 70_[4]	Lover H	+5-10 Favor
End Teacher-H without doing anything	Confused H	No change
End Teacher-H without giving orgasm	Disappointed H	-10-20 H
End Teacher-H with 1+ orgasms	H Approved	-20-30 H

Notes:

In vanilla game, it's not possible to end First Time H without taking her virginity
This disregards location and # of orgasms, so long as both partners cum once.
If Public and Cum 3+, either ending can be randomly chosen
The ending Favor/H ranges are randomly chosen, weighted by Exp Lvl. Lower results add less Favor and reduce more H. If Girlfriend conditions are met, Lover H is added to the random endings, heavily weighted toward Lover.

Love H / Perfect H result

This is still experimental, may not give the same result as desired.

Thank you for your humble patience and sorry for the inconvenience.

To achieve a Love H ending dialogue (all have 2 lines of dialogue except Motherly personality) that increases love rating without decreasing H meter. You will need to find the girl's sweet spot that is unexplained from the game's tutorial.

Sweet Spot Guide, note that the mid is between low and high speed

If you notice that the cumming bar is increasing faster than normal, that means you hit the girl's sweet spot which is your piston speed, continue staying on the sweet spot will trigger the girl's reaction earlier (around midway) before you hit the 1st cumming threshold bar (not the final one that makes the girl cum). Compared to the normal usual one which involves randomly moving to get girl's reaction earlier, this guide uses auto-mode for precise location of the sweet spot. Each girl can prefer gentle or intense H, for example, a girl with Lady Personality on Risky days will prefer gentle H than an intense one, hitting the sweet spot gently and cum together 1-2 times will always give the perfect H ending dialogue. Kissing while piston increases the intensity so it may moves you closer or farther from the sweet spot.

A Girl with Slutty trait may have more sweet spots than the one who doesn't.

There a total of 16 Girl Reactions after cumming, the variables are Gentle-Intense, Slow-Fast, Risky-Safe, and Kissing-NoKissing. (e.g. Gentle Fast Risky No-Kissing) The Reactions itself doesn't indicate whether or not you get this Love H result but the variables are. (Cumming on Gentle, or Intense gives different set of reactions .. if the girl has more dialogue lines for it)

Examining those variables and getting this desired result is very useful if you want to maintain the girl's Nympho state without going overboard. (e.g. cumming inside 2+ times)

useful note: For nymphos, cumming more than 2 times inside her is the easiest way to reach the same result but you will not receive the love H ending dialogue instead you get the exhausted dialogue. Use this as an alternative countermeasure if you want a guaranteed success to maintain nympho state.

The table below are the H preference based on the Personality for the most efficient way to get the love H dialogue:

Important: Some sweet spot locations are very precise, so it is highly possible to miss (just with a slight bit of mouse scrolling could miss the sweet spot)

*above are tested thoroughly with Nympho girl, in non-public place (e.g. nursery) at the school without any other girls nearby, cumming together once without kissing, and staying on the same pace until cum with auto-mode for precise location.

**The BOLD ones are tested both at home and at school, a jolly guaranteed success.
