You came home unexpectedly and caught your daddy together with your step-sister who....had oral sex....and who didn't suspect that their secret would be revealed... you are lucky that you are a reserved character, and what you saw shocked you so much that you couldn't really say a word. Then your step-sister took the initiative and informed you... that our daddy has been wanting you to suck him off for a long time.... Your step-sister starts flirting, giving in, coaxing you, because no one will know, it will be a shared secret from your mom. Your feelings are mixed, but you can feel your dick already giving consent. Well, you've never heard anything that made your pulse race as much as the thought of giving your daddy a blowjob. You decided to watch your step-sister do it. She cleverly talked you up, and turned you on with her blowjob for daddy and you didn't notice that his cock went into your mouth. And then it's all a blur. A haze of satisfaction and relaxation.
