A possible plot is that Kaneki discovers his pregnancy during a time of great turmoil in the ghoul world. He has to keep it a secret at first because of the danger it could bring. Tsukiyama, on the other hand, is eager to announce it to the world as a sign of their unique bond. This causes tension between them, but as the pregnancy progresses, they realize they need to work together to face the challenges that come with it, like finding a safe place to give birth and dealing with potential threats from both ghoul and human sides.
Another plot could revolve around how they deal with the reactions of the other characters. Some might be accepting, while others could be horrified or even try to harm Kaneki. Tsukiyama would have to use his influence and power to protect Kaneki and their unborn child. The pregnancy could also be a symbol of a new beginning for the relationship between ghouls and humans, if they can prove that such a thing can happen and be managed.
Well, at first, it might be a bit of a shock for both of them. Tsukiyama, who is used to a certain dynamic with Kaneki, would have to adjust to being more of a caretaker. Kaneki would also have to deal with the physical and hormonal changes of pregnancy, which could make him moody. But as time goes on, they would grow closer. Tsukiyama would be there for every doctor's visit (if there are such things in their world), and they would start planning for their future together as a family. They would have to face their own insecurities and fears about becoming parents, but through it all, their love for each other would deepen.
One common theme is the exploration of their complex relationship. Given their different natures, fanfictions often focus on how they come to understand and accept each other. For example, Tsukiyama's initial predatory nature towards Kaneki and how that changes over time.
One great piece of tsukiyama x kaneki fanfiction is 'The Unlikely Bond'. It delves into how their relationship could develop in an alternate universe where they have to team up against a common enemy. It beautifully portrays the complex emotions between them.

Inuyasha accidentally activates it and becomes pregnant. Koga is confused but also excited. They then have to find a way to keep Inuyasha safe during the pregnancy. Maybe they seek help from a wise old priestess who is hesitant to get involved at first.

One idea could be exploring how the relationship between Spiderman and Venom changes during the pregnancy. Maybe they become more protective of each other.
One plot idea could be that Soul discovers Blackstar is pregnant and they have to deal with the shock together. They might struggle to keep it a secret from their friends at first.
