HMN-906 | A consultation room exclusively for masochistic men. It's okay even if you're a weak masochist. A maternal nymphomaniac invites you to cum inside her pussy and unleash your sexual desires. Natsu Tojo

"M-O Lab" is an organization dedicated to liberating men from sexual stress and supporting those who suffer under the pressure to conform to "machismo" (traditional masculinity) in society or at home. This comedy-drama centers on a non-profit organization that provides mental support—reassuring men that "it’s perfectly okay to be an 'M-type' (submissive/masochistic-leaning) man"—and works to destigmatize such preferences. The story follows staff member Natsu Tojo as she tackles a wide array of sexual concerns brought to the office, working tirelessly in her role as a "sexual carer." Natchan is here to cheer on all the "M-type" men with everything she’s got!
