Kneeling before my stepbro, I'm ravenous for his cock. I lick and suck, my head bobbing furiously as I take him to the back of my throat. His cock twitches, and I know he's close. I prepare, eyes watering but determined. His cum shoots out, coating my tongue and filling my mouth. I gulp it down greedily, wanting every last drop, the taste of him sending shivers down my spine.
