"I do administrative work at my dad's company..." says Seina, who lives with her family in Hiroo. She's in her third year as a working adult. Her incredibly fair skin, plump breasts, and well-groomed movements, down to her fingertips, all exude an undeniable sense of good upbringing. She's a true lady. "My body looks so beautiful when a professional takes the pictures," she says shyly during the pre-shoot interview, her eyes flickering with curiosity and desire. "Actually, I'm interested in naughty things... and being bullied, but I've never had that kind of experience..." Just tying her hands and blindfolding her makes her pussy soaking wet, a true masochist. "Just for today, I want to be treated like an object... and be treated so roughly that I break..." Because she's lived her life as a "good girl," she has an insatiable desire to be "broken." She orgasms wildly, squirting cum everywhere, until she breaks. The ultimate masochistic sex. Don't miss it.
