There's no mod for "Cumflation" yet, and no, it is not planned to be implemented into the game, and probably will never be added into the game.
And, please note that NSFW suggestions are now limited to Patreon & SubscribeStar members only. You’re still welcome to create topics and discuss ideas with other users, but NSFW feature suggestions made on Itch will not be prioritized or considered by the developer.
Thank you for understanding, and have a wonderful day.
