The first one to cum gets locked straight back into chastity

I've told them that the first one to cum gets locked straight back into chastity, has his cum allowance cut in half & has to suck the other one to each of his allowed orgasms for the next 12 months.

It's just so funny to see them both sucking so furiously, whilst desperately trying to hold back all of that backed up cum.

"Come on you pair of sluts, if I don't see a winner in the next 5 minutes you'll both be treated as the loser"
