IMTU, the players once had to free a young woman who was forced to work in a brothel. Her brother had contacted the players about the situation. Afterwards, they transported the pair off world.
IIRC, they did recon on the establishment. Then a couple of nights later, several of the players went to the establishment. Then they met up at a predetermined location at a predetermined time. Another player, who had psi training and the teleport ability, "jumped" into the establishment bearing weapons for all. They then went to work.
And also IMTU, interspecies coupling is common, but usually not talked about except in the seedier parts of startowns. Everyone knows it goes on, and if that's your thing, you can find establishments catering to your desires. But no offspring ever result from this. It's genetically impossible to occur naturally.
