This is a type of oral sex. The term originates from the Latin word irrumo (to suckle, to make suck) in its noun form, irrumatio. Unlike fellatio, where the woman leads the act, in iruma chio the man leads and makes his partner take his penis into their mouth. The man stands while his partner kneels, taking the penis into their mouth. He places his hands on her shoulders or head and moves back and forth. Alternatively, he straddles over his partner who is lying on their back, inserting and removing his penis from their mouth to achieve pleasure. Apart from physical pain during the act, it can cause temporomandibular joint disorder or oral thrush. If the male's penis is long or thick, there is a risk of choking or causing fear during the act. Performing this act without the partner's consent is generally considered ●●● and a dangerous sexual behavior.
