As Zak Bishop enters the room he shares with his step-brother, he finds Asher Devin in a mild state of anxious panic. It seems Asher is overly preoccupied with dick size, and whether or not he measures up. Zak tells him he's probably fine, but if he's that worried he should just measure it. Asher seems incredulous, so Zak helps him out, grabbing him by the shaft and stretching Asher's cock to full length. Zak grips Asher's member by the base and feels him get harder. Asher's measurements are impressive, but now Zak decides to manipulate the situation to his benefit, asking Asher if he's sure he's got the stamina. Asher seems confused, so Zak leads the way, explaining to Asher that having a big cock and knowing how to use it are two separate things. Zak tells Asher he should practice, and since there's no one else around, Zak volunteers to help his brother out, sucking him off until Asher is good and hard enough to give put his fucking skills to the test. He immediately proves to be a natural, taking Zak by the waist and pulling him back closer, pounding him from behind as Zak grabs a hold of the bed. Zak mounts Asher and rides him reverse, bouncing his ass up and down on his brother's cock, before they both spit their loads in a steamy, messy exercise of brotherly bonding. Enjoy!
