The first five walkthroughs were the possible beginnings, now I will show you the possible events and endings you may encounter.
Lets start with the most obvious and most requested: Sex on the couch.
Dance in the living room* (any music) Change music Go somewhere else Go to the living room Kiss her (to open up the couch make out scene) Massage her shoulders Grab her breasts Ask her to take her shirt off (or "kiss her" again, then this) Rub her thighs Ask her to take her pants off Ask her to take her panties off Massage her butt Massage her back Ask to stay the night Climb into bed Kiss Her Goodbye
After the kiss part there are many variants on the couch make out scene, feel free to explore.
*if this is not an option, get the latest build. “Go to the living room” then “Dance to music” is a two step substitute.
Historical note: If this date scenario seems a bit odd, because basically all you did is go to her house, eat, then have sex, it is because the very first version of Date Ariane was basically this: there was no backyard, downtown, park, or anything else to do outside of her house. So this is what the game was at the very beginning and I kept on adding to it.
