Gagisthenics
Gagisthenics is when you do weird throat workouts and train your gag reflex so you can take a huge cock without throwing up.
I did gagisthenics every day for a month. Now I can take a cock the size of a brick without blinking.
My gagisthenics routine involves gargling with bleach. It works, but it smells like a dead cat.
She did gagisthenics just to deep throat a guy. He called her a human vacuum.
