The nuance that arises from the word "insertion" is slightly off from the active connotation. All you jack-off maniacs out there, this work is a sure buy. The eyelash makeup is a bit emphasized, which might be unfamiliar to some, but that quickly becomes irrelevant. Because your eyes will be glued to the massive cleavage, the jack-off hole, the tit-pussy, and the breast onahole.
The outfit from 00:11:53 is incredibly erotic. What is this? The moment it appeared on the display, I got a deep, hard erection from my hip bone. It's truly a tit-fuck hole. Here, I want to pose a question. Why do we describe tit-fucking as a "hole"? Originally, a hole is a mysterious existence—like how a donut's hole disappears when you eat it, it's a metaphysical concept with no mass. It only exists when there's "something" around it. In other words, we are looking at "that something," and the tit-fuck hole is only established when surrounded by breast flesh. We jack-off maniacs are looking at boobs. So, why say "hole"? Because we jack-off maniacs perceive the world (the female body) based on the rod in our crotch. Because there's a rod, we find a hole within "that something"; because there's a phallus, we discover a tit-fuck hole within the breasts. The outfit from 00:11:53 visualizes this hole that should be invisible, that should have no mass. The matching panties—too special to just be called that—have a ring on the front cloth-like bondage, but this isn't a hole. Because a phallus won't fit inside. Maybe some folks with that fetish are into it, but I'm a jack-off maniac, so this ring is just a stage prop, a supporting actor to emphasize the jack-off hole, the tit-pussy, and the breast onahole.
Let's return to the jack-off hole talk. Around 00:20, insertion begins. The curved, erect phallus tries to escape upward into the cleavage but is immediately wrapped by the bursting breasts. "Insertion" is an active act, but in this scene, while the male actor actively inserts, it's driven by the actress, boob-driven from there on. That's a bit off from the active nuance associated with the word "insertion." Normally, a hole disappears and ceases to exist when filled. In other words, to flaunt the "existence of the jack-off hole," you must physically keep moving the rod that fills it, constantly proving it's a "hole" in relation. The tit-fuck exists, and the tit-fuck hole continues to be established.
