You cooperate

You decide to play along. It's not like you have much of a choice and you have a feeling that resisting against these two powerful siblings will lead to more pain for yourself.

You relax your ass as you feel Max's fingers on your asshole as you move your head on Phoebe's cock again.

"Good decision, fish. If you had resisted, I would have ravaged you without any lube." Max tells you as he applies lube on his finger and slides them in to lubricate your anal passageway. Despite the lube, you scream in pain as your anal cherry is popped.

Phoebe muffles the sound of your scream by shoving her dick down your throat. Your anal passage slowly adjust around his fingers as he applies lube all around. He then takes them out and slowly positions himself behind you. You brace yourself as you feel his dick positioned at your asshole.
