Loved the Town Girl Aftermath, not too difficult if you play it serious, but still very sexy, also noticed if you let them kick you like 9-10 times, it's pretty much a certain loss, regardless of how high your stats and HP are, as "C"'s kick just decimates your HP
Would have liked more content involving the town girls, hopefully in their next game they do more, but it was still good
The other three Aftermaths are kind of disappointing though, two have no real challenge, you basically just watch a story, boring
The Sophia one was the biggest letdown as the sex fight scenes are boring (she doesn't take on any poses and doesn't move in response to your actions, such as if you try to finger her or fondle her), and you can't actually beat her in the physical fight, and even if you do really in the fight well, she just suddenly beats you down, this was the biggest letdown for me since Sophia is my favorite girl from the game, and making it that she is suddenly this expert fighter who can beat down the Hero without any effort undercuts what made the earlier defeats so sexy, losing to her even though she is a weak fighter is what was so good, making her an amazing fighter who can't lose undercuts that completely.
So TL;DR, the aftermath update is only worth it for the Town Girl fight, but pity there wasn't more town girl content.
