Done. The dev cut us off at the knees on this one. After all that grind and build up, one pissant little hint of a sex scene with each girl and he's out. Prick.
Man, I hate to pile-on... it kind of feels like the dev is under attack, but you're not wrong. Room for Rent, My Best Friends Daughter, My First Love, all of them were exactly the same: painful grindfests with no ending. It's strange. How can this guy have the patience to create thousands of trigger events, but he can't be bothered to make a simple ending?
If the games were garbage, nobody would care, but they're not garbage. There's some decent content! The CeLaVie games have some great artwork and decent storylines. They're 90% of the way finished, they just need a final push. They need closure. I know the dev works solo, maybe he just needs a helper to get him through the wall he's built to finish the story. Here, I'll do it!
Alright Bob, finishing up My Friend's Daughter is simple. You just need to add one more season that's basically an end-game mode. The main character has won. Bob is king. All of the girls have given in to his lecherous desires. You can fuck any girl at any time. What do you want to do after lunch? I think I'll go fuck Sam on the beach. What do you want to do after dinner? I think I'll go fuck June in the sauna. Then, add a short little bonus for each girl. Maybe you convince one to do anal sex. Maybe you get a threesome with two of them, and they urge each other to go further and further until eventually they're letting you ejaculate inside of them - then their ending is: they both get pregnant. Maybe you convince one of them to let you record a video while you fuck her, so her big ending is: she becomes a pornstar for your new old/young fetish website.
Not only would this give you a little end-game mode for players to enjoy, but it would wrap up all of the storylines. It really wouldn't take much more effort than it took to create each of the other 9 seasons you've already created.
P.S. Oh and for the love of god, give us some variety. I get that old/young is your kink, but players have had nothing but young, petite, teenaged girls with alabaster skin to fuck. Give players something new. Give the main character a married milf that will cheat on her husband with the main character. Give players a black girl, an Asian girl with huge tits, a Latina girl with a fat ass that they can buttfuck. It'll make the games more interesting!
