You will...beg him to stop

You know that if that was low setting, there is no way in hell that you'll survive something much stronger. You have to avoid it at all cost. You'll lose some of your dignity, but it is better than the alternative.

"Please" you say "that's enough."

He smirks and asks "That's enough what?"

"That's enough, master."

"Hm, I could stop. But you have to do something for me."

At the last moment you stop yourself from shouting "anything!", instead you ask "what do I have to do master?"

"Oh, nothing special, you just have to admit that you are a slut that loves sucking cock. And be convincing."

Ah, what the hell, you expected something much worse.

"I'm nothing more than a dirty slut. I love sucking cocks and I'm doing it night and day. If I'm not doing it, I' dreaming about it. When I meet a new boy I'm always wondering how his cum tastes like and nothing will stop me from discovering that. I'm such a cumslut that if I drink from at least three people every day, I can't sleep."

You even get a little into a bullshit you are telling, you feel that you are getting excited. When you are finished, Gavin just stands in front of you and smirks. Now you realize what you just said. Fuck, he outsmarted and outplayed you. In theory you should be happy that you survived this day, but in reality you feel like you experienced a really humiliating defeat.
