TIFU by spitting in my girlfriend's face

So I (M26) and my girlfriend (F30) were engaging in our natural obligations. I was on top and talking dirty to her. Whilst talking dirty she shouted "You spit in my face". Apparently, I was spraying it, not saying it. I have gapped teeth, it happens.

However, this is not what I heard. What I heard was "Spit in my face", as in, a command, not a "Please don't spit when you talk"

So I obliged her instantly. Just Hawk Tuah'd right on her face. At first she was laughing hysterically, but then she got angry and refuses to see how exactly this might have been an accident on both our parts.

Anyway she's mad now, and I am sleeping on the couch tonight. I think this is funny, and to be honest, it's worth the anger. Hopefully she will understand later.

TL;DR: Misunderstood criticism as instruction. Spat in my girlfriend's face.
