The idea is that you don't expect a pizza delivery boy to suddenly knock you on your ass and hold you down and whip his dick out while you're kicking and screaming. Even if it's not 100% full rape (you literally can't rape the willing here), the emotional barrage one would experience initially upon the seeming betrayal of trust would approach the rape meter close enough, like 40-60% at least, which is not emotional scarring territory, but it is also the intent. The sudden onset of rape also makes it always carry that charge and they may not even remember they consented to be raped at first, so you'd approach like 75%-80% level of rape. Alternatively, just feeling the ever-presence of rape can be enough to get your heart beating. It's like watching a horror movie. Of course there will be jumpscares, but you'll still jump. Unlike movies, it's also a full 3D experience that is supposed to make your entire existence a horror at least for a bit, tear you from safety.
Of course it is not the real thing, but there are still degrees to it. It's like playing a remaster of a beloved game which actually runs on a new engine. You may not feel like it is actually the real thing at first, but if it's executed correctly, you'll stop noticing the difference.
It's also implied that the rapee also has enough mental and physical stamina to withstand the visitation, so even though the stop word is right there, she'd rather thrust the trip into herself than stop it. Of course, that'd imply that she's a bit of a psycho, but you already know what you just came into.
