Shoto dislikes kissing demons but Ihsan is an exception
Shoto is attracted to the scent and taste of this plant demon. Even when he’s not injured or ill, he would often sneak a kiss from his servant from time to time, or sometimes he just needs sex to release his primal instincts
Ihsan, on the other hand, doesn’t complain, because during their fucking Shoto always has to bleed for Ihsan to drink. Because Shoto forbids Ihsan from eating human flesh (though Ihsan can eat regular animal meat, he complains that it’s nowhere near as tasty as human flesh)
Shoto is the only one who can truly satisfy Ihsan sexually
Nobody else in the guild can please Ihsan, not even a single one
Their sex may appear rough and savage, but both are eager participants
