Another day, another time-stop story pulled out of upload purgatory. This doujin by Binbi was released digitally in early 2019, and is part of the anthology series '強制お仕置きタイム', a precursor to the current series '矯正!お仕置きタイム' (after presumably changing labels or something).
[Story summary using rudimentary Google Translate] Our time-stopping protagonist, Katsumi, is out for revenge. Katsumi's brother is visiting, and along with him is his wife Natsumi and their baby son. As it turns out, Natsumi was Katsumi's girlfriend in high school, but she dumped him in favor of his brother. Katsumi develops gynophobia from this experience, and he grows further emotionally unstable when Natsumi and his brother got married, thereby making her family now. The compounding shock causes Katsumi to develop his time-stopping powers. He uses this power to vent his frustration, raping Natsumi at just about every opportunity, and he especially enjoys doing it in his brother's room (all while he's right next to the guy). Several months pass and Natsumi comes to visit again, this time with a new baby. The story ends with the mother-in-law commenting that the baby has the same look that Katsumi used to have when he was a kid, implying that the second child is actually his.
