I Catch my Perverted Stepbrother Masturbating and I can't Wait to Suck his Big Cock

In the heat of the moment, you're tapping your stepbrother's door when you spots him through the crack, his hand wrapped around his thick, throbbing cock. You can't help but watch as he jerks off, his eyes closed, lost in his own pleasure. You're so turned on, you can't resist the urge to join him. You slip into his room, your heart pounding, your pussy wet with anticipation. He's so close you can see every vein on his cock as it pulses with blood. You can't believe how big it is, and you can't wait to feel it in your mouth. You drop to your knees, your hands shaking as you reach up to take his cock in your mouth. He groans, his eyes flying open in surprise, but he doesn't stop you. You start to suck, your head bobbing up and down, your lips sliding along the length of his shaft. He tastes so good, so salty and musky, it drives you wild. You can feel his cock throbbing in your mouth, and you know he's close. You want to take him all the way, to feel his hot cum in your throat. You reach up and cup his balls, squeezing gently as you deepthroat him, his cock hitting the back of your throat. He moans, his hands fisting your hair, guiding you as you suck him off. You're so lost in the moment, you don't even notice your mom walking in until she's standing right behind you. You feel her hand on your shoulder, pulling you up as she whispers in your ear, "Don't stop, I want to join in too." And so, the three of you engage in a wild, taboo sexual encounter, filled with moans, groans, and loud screams of pleasure.
