For bitch boys, eating your cum is always the right thing to do. It doesn't matter whether your orgasm is full or ruined, you still have to clean up your mess properly, licking it all up like it never happened at all. Broken "men" like you aren't meant to have the pleasure leading up to either one so the evidence of it should be erased completely by putting it back into your body.
And, lucky you, cum from a ruined orgasm tastes so much better than cum from a full orgasm. Don't believe Me? Start stroking. You'll be tasting one of each so you can see how right I am.
