My first message here:
To cat01:
Day 3, first she's sleeping, move her skirt, spread her legs, rub her a while. After that, move her pants to the left, if she's wet, close her legs and pull off her pants. Spread her legs again, play a little with her, then use you penish till the end. This part is important, you should not penetrate her (don't remember if you can anyway) Once she's in green shirt, spread strongly here legs, once she's laying down, spread her legs and play with her but not too long; in fact, the less the merryer. Use penish and, this is a must, DON'T penetrate her; push her pussy to the end untill the penish slips out the pussy and hold there. You must then rub her clit with the penish untill you cum on her belly (again, never go too down or you'll penetrate her; you don't want that now, trust me) If you do this right, you'll unlock the blowjob scene. Once in that scene, save the game and proced as you wish (she can lick, blow or masturbate; the last one can go faster after a while), cumming in mouth or face, as you like.
Day 4, first, click on her schoolbag; you'll see how your char take some kind of pencil case out of it (don't know what's for), second, WAIT her to give you some of that food she's eating. Accept it (left click on food) and wait till your char shouts something in red letters; by doing those 2 things, you'll get an extra option (usualy just 2) and something more, you'll be able to make sex (cum) three times instead the usual 1. Once both things are done, click on her skirt: first option as usual, second she'll be on swimming costume, and the tird option will make her go naked. You can touch her breast and rub her pussy. Do it softly, and she'll spread her legs by her own. From here as usual, penish out, and if you choose the first option, rub her softly for a while, 'cause that will unlock another icon, a hand to finger her (just upon the penish icon)
You can finger her that way in both positions, not just the doggy one. From there, rub as you wish, fuck her, etc... Just to know, when you are almost to cum you'll get a very quick message; if you pull off the penish quickly, you'll cum over her instead of inside her.
Congratulations, you have just get a 100%

(Day 1 4/4, day 2 5/5 day 3 39/39 and day 4 82/82)
P.S.: she likes a lot more going softly and slowly than quick and strongly; I haven't do it myself, but you can make her to ask for penetrate, and you can get her "moving" (I mean, she will move to get fucked instead of you pushing)
P.P.S.: sorry for any misspelling-errors; I'm not a good english-speaker.
EDIT: have just discover what's the pencil case for, but don't know how to get that scene; you can masturbate her with a ball-pen if she's dressed.
