In a world of BDSM it's illegal for a dominate to fall in love with another dominant, same goes for the submissive's.
It's also very rare for someone to have more than one submissive...let alone a relationship with 2 Dom's and 2 Sub's, but then again the boys aren't your ordinary couple.
"You can't silence us anymore."
