I don't know which is better in this case: a "Plowing" joke or a "Huge tracks of Land" joke. I could even go with the huge melons and a butt shaped like a peach or deflowering... but it's too easy.
so in the near future monstergirls are able to bear incubi? in that case one of their bigest dream come true but i think not any race is able to do this.
