Tense times with stepbrother's urges - Addison Graham, Markie More

Things have been a little tense around the house since Addison seduced his step-brother Markie a few weeks ago. Markie's denial has given way to open lust, so as Addison comes into the bathroom to brush his teeth while Markie is showering, he cracks the shower door and steals a look at Addison's sweet ass as he begins to stroke his cock. Addison can see him in the mirror, and the thought of taking Markie's raw cock is dominating his mind. Addison takes a look over his shoulder and sees Markie staring back at him intently, toweling off and making his way over to the vanity where he presses his lips against Addison's back, sliding his mouth down Addison's spine and then back up to his neck, where they kiss hard.
