When Tomoya walks in on Yukine masturbating, she decides to play a taste-test a game with him.
In the second story, newlywed Nagisa wants a goodbye kiss from Tomoya. But Tomoya misunderstands the request.

In its original release, this doujin had a third story: a bad end for Kyou, which the comments here and elsewhere agreed was a tonal mismatch for the first two stories. This 2023 colorized decensored release with a new translation keeps things light and fluffy, so it omits this third story. (Maybe this further heightens the feeling of Kyou NTR.)

Cleaning and decensoring by Borantio

Decucking doujins is based and it's a win-win situation since cucks feel like they've been cheated out of complete release and get meta arousal from it.
