Okay, hear me out. Actually use it as a gimp mask, for BDSM stuff. Put on big headphones and play your own voice back into your ears full volume while someone edges you and slaps you around a bit, forcing you to moan into your own ears super loud if you can’t keep your mouth shut and stop complaining, while also muffling your cries so nobody but you has to hear it.

Anyone know the brand?

I don’t even think this is selfish. It’s only selfish to put yourself first when you have kids who depend on you. People choose the responsibilities they take on in life, and you don’t owe the world anything here. If you don’t have kids, you’re able to do more for yourself, and anyone who calls you selfish for it may actually be a bit jealous, in which case they should reassess their own parental priorities.
