ITT we post toys that should exist.

Fuckagotchi: It would be like a tamaotchi but with waifus and husbandus instead of pets. In addition to normal tamagotchi stuff they would have a horniness meter and if you left them unsatisfied for too long they would become incels. If you fed them too much they would become BBW, if you didn't clean up their poo they would get into scat, if you didn't bathe them enough they would become stinky braphogs.
