Who do you think is the supreme Sinnoh waifu?
Cynthia? If so, you're a fucking normie.
Dawn? If so, what the fuck is wrong with you?
Gardenia? If so, you're just flat out wrong.
No, the supreme Sinnoh waifu is Dialga.
Dialga is the best choice for female Pokémon and male human breeding. Its pussy is so enormous that you can fuck one for hours without having a sore dick. It can also take over 30 loads of cum without any fatigue. It has no fur, meaning you can eat one out without getting a hairy tounge. And because Dialga can control time, you can fuck it without any worries about being late for work. It has the ability Pressure, meaning that you can be able to have a better sensation when fucking one roughly. So, time control + Pressure + huge body, makes it the peak Sinnoh waifu and the most compatible Pokémon for human cock.
