Dr. Yuina, a proctologist, is sent by her hospital director to file a complaint against a medical device company. However, she falls into a trap when the 'device' turns out to be a sex machine. Now, she is forced to become a sexual slave for the company representative, realizing too late that the entire situation was orchestrated by her own director.




















I apologize to those who like glasses, but I just feel like wearing them looks out of place.
With her theatrical acting and saggy breasts, maybe it's someone's cup of tea, but personally, this was a dud. A shame!
The story and acting are very average, but the incredibly soft-looking massive breasts make it worth watching. I was jealous of the actor while watching. I want to watch them bounce from below, squeeze them, suck on them, and just go wild! The glasses mentioned in the title and the body stockings in the second half are a plus. Personally, I prefer tighter-knit stockings, though.
Yuina Sakurano has incredibly soft-looking, massive breasts that are just erotic. She openly identifies as a masochist. Even though she's supposed to act like she hates being forced, she clearly enjoys it so much that she can't help but smirkโshe's a true masochist. She plays a strong-willed doctor, but the gap between that and her cute, delicate voice is great. Personally, I love that fragile-sounding voice. The bondage-style sexy lingerie with black straps, a series staple, and the new coarse-mesh purple body stocking are both very erotic. The handjobs using her soft, massive breasts look amazing. Personally, I was a bit disappointed that she didn't actually use the masturbation machine she brought after complaining to the manufacturer; I really wanted to see that in the drama. Also, during the 3P, she wears a gag, but there's no collar! Since the title mentions a 'collar,' I really wanted her to wear one. It looked like a collar when she took the gag off, so that was okay... Regardless, the actress's massive breasts and her intense performance are so erotic; she's the perfect actress for 'training' themes involving masochistic female slaves. She feels everything, climaxes instantly, and hits multiple internal orgasms while being pounded hard. I had a great impression of this work with her. I definitely want to see more of her.
