Sir, It’s Time for You to Kneel

Izumi Ayato is a company president who's also a sub and gay. Life isn't easy for him, both in work and personal life. While Izumi had played with different doms, there was still a feeling of something missing. Enter the new secretary, Yuma Kosaka. While Yuma is proving to be a great secretary, that doesn't mean he'd be great as a dom – on second thought – the two might be compatible after all.
