Found my Step Bro Masturbating after my Workout and I ask him for Lots of CUM

After a sweaty, intense workout, you catch your stepbro in the act of stroking his massive, throbbing cock. You've seen him before, but never like this. You can't help but approach him, your heart racing with anticipation. He turns to you, his eyes filled with a mix of surprise and desire. You lean in, asking him if he wants to help you relax after your workout. He nods, his hand still stroking his impressive shaft. You sink to your knees, taking the entire length of his huge white cock into your mouth. You can feel his veins pulsing against your lips. You lick and suck, your head bobbing up and down, creating a rhythmic motion. He groans, his breath hitching as you take him deeper. You look up at him, your eyes watering slightly, but you don't stop. You want more. You want it all. You want him to fill you with his thick, hot cum. You ask him to cum on your face, and he obliges. He grips your head, guiding you to the perfect position as he unleashes a torrent of hot cum, covering your face and hair. You lick it off, savoring the taste of him. This is your stepbro, your secret fantasy, and you'll never look at him the same way again.
