No animated scenes yet. You can't just jump to lewd stuff, you must progress your relationship with the character first. You can use cheats and easy mode if you don't want grind though. There are about 5-6 main girls and randomized npcs than can go up to 200, you can change the number and gender ratio. No endgame so can't say anything about gameplay time
Overall I think it's a cool game, you might want to check it out. A bit hard to get used to at first, but not annoying
