Mucinex High

The worst high you will ever have. The room will start spinning. You will vomit, and have diarrhea through out the entire high. And the comedown is insanely terrible. You feel like a literal piece of shit, and it will make you want to die.

Mucinex Serpent 

You make your spouse OD on Mucinex and facefuck them in the nose. You then ejaculate in their nose, so a string of mucus flies out. You proceed to ejaculate in her nose, while going in deeper until they don't have a stuffy nose anymore.

I just gave my wife a Mucinex Serpent a year ago. She hasn't had a stuffy nose since
