Welp, nothing outstanding for little time now...
If you haven't played the classics like Summer Memories and Town of Passion then...get on it!
But if not, I've recently played Kingdom of Subversion which was surprisingly great! We got some animations for the latter part of the game and the scenes are quite hot with a good amount of content. The only downside is that the MC isn't...cute, or in better term, you don't actually see his face. Still built like a shota tho.
I've suggested Spooky Milk Life in an older post but it got a few updates from back then.
There's also Succubus Affection which is in my opinion one of the best platformer games, which includes a Cute Shota MC, but from what I remember the game wasn't centered around the fact that he owned a big PP.
