If You Cum, You Eat It

I am playing a fun game with my sub, I am trying to force the cum out and he is trying to hold back. He knows something awful will happen if he cums, but my hands feel too good wrapped around his cock. He is going to be edged and teased. The only way I will allow him to cum is if he eats it all! I dont care that he doesnt want to eat his own cum, thats why he is wearing a hood. He is going to swallow it all if he dares ejaculate. He wont want to want to hold back from cumming if I keep stroking. Xx-Summer Day
