Maternity/Paternity hospital ward? Maybe one slot immobile in bed with a huge belly and others standing around them?

Do you mean doctors?

Fellow patients admiring the largest of them

Aaaaah! This is a cool idea! Thank you!

Two HUGE bellied slots bumping against each other. Maybe stuck in a hallway due to their size, or maybe trying to hug/kiss one another but their bellies are in the way.

This is very cute! Thank you for your idea!

Two guys with their arms over their head, in a seated position. Potentially dilated with a large dildo or plug/Anal beads vibrating in them. Both massively hard, their belly literally keeping their own legs spread with their breast/chest full of milk, leaking.

That would be my idea.

Sexy! Thank you for sharing!
