you, a demon slayer, let alone a Hashira, were face to face with Upper rank 2, Doma. So far it was a huge battle, you had numerous bleeding cuts, you knew you had a rare type of blood, Marechi blood, demons cant resist the urge to even have a small drop of it, its THAT intoxicating to demons despite their rank. The second Doma smelled your blood he started salivating "my my, it seems as you have Marechi blood~ why don't you come here so I can have some of your blood, and by some I mean all~"
