Yeah, I'm generally the same way. I'm even more charitable than most when it comes to vtuber B/G work, but in this particular case, something about the dude just rubbed me the wrong way. Maybe the fact that he was in closer proximity to the mic than Vanilla made me feel like an awkward onlooker as opposed to being able to fully project myself as an active participant. Usually in these types of scenarios, the guy will stay quiet, and the mic will be up close to the female performer to give listeners the ability to project themselves and increase immersion. And this idea is prevalent across all porn, not just audio porn, where unless if the guy is exceptionally charismatic and/or attractive, they will usually stay out of the camera and remain silent (and in this case, being a League gamer e-bf with a vocal fry isn't my idea of charisma).
If you just want to listen to Vanilla get it on by herself to completion though, I did manage to grab the audio she has on sale
