One in-game day was indeed too little!
Honestly loving the amount of choices, for the game with the "sister" for example, lesser avns would have had just one choice, on wheter to play or not, MC asking for something spicier automatically, but giving the player two choices, one on if to play, and the other on what to ask after winning, is the level of interaction I want and appreciate, props for it!
As to what to improve, imo you should make so (most) animations don't loop back to the start, but stop once they reach their end point. For example, it's weird to see the "mom" walk out of the bathroom, stop in front of MC, then reapper in front of the bathroom to walk the hallway again. Such animations should just play once, and freze on the last frame until the player clicks.
Loking forward to playing future releases, best of lucks with the game!
EDIT: Also, maybe you should wait until the next release so the game has more content, but consider promoting it on the AVN subreddits!
