Iroha Meru-chan is a middle-aged killer who says her favorite type of man is an older man. The older man she met on social media during the day is a masochist who suffocates her as he sits on her face. He's a pervert who gets an erection when he drools on her. At night, she goes to her close older man's house and he grabs her masochistic Kokoro with a deep throat blowjob. They're close enough that being screwed and creampies are commonplace. She's got the ability to enjoy a completely different type of man, as you'd expect. Meru-chan is full of charm.
