If You Cum, You Eat It Handjob

I am playing a fun game with my sub, I am trying to get that 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 don't care that he doesn't 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 won't want to want to hold back from cumming if I keep stroking. xx-Summer Day
