Colby Chambers isn’t shy about certain things. If he’s into you, for instance, and wants to get it on there will be no doubt what’s on his mind. In this week’s ColbyKnox update, Grant Ducati stands on a patio. The stud is lifting weights, looking extremely tasty in white underwear. As he works on those bulging biceps Colby is behind the patio window, looking Grant over. He’s also shaking his thick tool. After finishing his reps Grant sits on a weight bench, waving to Colby to join him. “Couldn’t help it,” Colby says, strolling out. “It’s all good,” Grant replies. The boys kiss. Colby caresses Grant’s arms and chest. When Grant gets on his back Colby stands over him, guiding his tool to the cutie’s open mouth. “Suck that dick,” Colby whispers. To make the request a little easier, Grant gets on his hands and knees. “Fuck, yeah,” Colby moans. “It feels good.” As he’s being serviced, Colby slaps one of Grant’s butt cheeks; he gets behind Grant and licks the boy’s tight hole. To give Colby complete access, Grant removes his underwear. Now Colby puts his face between the cheeks. When Colby stands up, Grant’s back arch is at a perfect angle. This helps Colby slowly fill him up with raw meat. Colby leans down and Grant turns his head so there can be more kissing. It’s a tight fit but Grant wants it. Colby pumps to the balls. Grant holds on, letting his ass be manhandled, There’s a position change; Grant is on his back, drawing those toned legs to his chest. The pounding resumes. Grant’s prostate is getting pulverized, making his toes bend. There’s nothing Grant can do to keep Colby from stretching him out. To be fair, Grant doesn’t want to do anything about it as long as he’s getting rammed. “Take my dick,” Colby exclaims. “It’s really good,” Grant whispers. As his hole is wrecked, he’s stroking his tool and Colby fondles Grant’s nuts. Both are close to busting loads and it’s a race to see who “loses.” Before that happens there’s an exquisite close-up of Colby’s tool drilling into Grant. We even get a glimpse of Colby’s butt hole clenching. He comes first, drenching Grant with jizz. After leaving his load on a sweat drenched Grant, Colby puts his stiff dick back inside him. The hard pounding returns and this is too much. Grant grabs Colby’s arm for support, jerking out a large load. The scene comes to a close with the camera focusing on Grant’s torso, hole, and thighs. All are covered in man milk and sweat
