The Lapines tribe consist of two castes of bunnies. The tall eared and lop eared.
The tall eared were naturally gifted physically. They are strong, durable, and have keen senses. They are usually deployed on the field to hunt and scout. They are also the tribe's primary military force againts enemies from out of the tribe.
The lop eared bunnies, on the other had, are more in tune with the nature. They are more intelligent, more artistic, and usually managed the affair within the tribe. They are also capable of casting simple magic, a remnant of the lost old arts, which no tall eared capable of doing.
Being rabbits, their sexual culture was one of the most developed among the other tribes.
In this tribe, it's free to mate with anyone within your own caste. Orgies are the norms. And the children that often resulted from such intercourse are treated as the children of the tribes. They are everyone's children, and everyone should help guide them so they could benefit the tribe in the future.
Inter caste mating rules were a bit more complex. The tall eared could choose any lop eared to mate and the lop eared are not allowed to refuse. They should present themselves to the tall eared when they need release and treat it as an honor. But sexual violence is strictly forbidden. If the lop eared was harmed during non consensual intercourse, then the tall eared will be held responsible.
But in practice, the lop eared themselves didn't mind to be picked as tall eared's sexual partner. Since they naturally have sexual drive far surpassed the tall eared. And it's a common conception among the lop eared that the tall eared males are a lot more satisfying for them than their fellow lop eared males.

They were the first to invent various sex toys and medicines to help made sex an even greater experience for everyone involved. They also discovered the art of contraception to control birth rate, thanks to how often population bomb happened within their tribe.
