As both older brother and father used Dan as the cock slut he was. Jeff heard his Dad grunt something as his thick cock thrusted into Dan’s mouth, the slut greedily taking as much into his already cum stained muzzle.
“I always fucking knew your brother was a slut, but I let him be since he was too old to punish. But now you...” he paused for a split second, grunting loudly as he send what felt like a splurt of cum into his moaning son’s mouth.
“I’m going to make sure you both get the fucking of your lifetimes. When I’m done, both of you won’t be able to walk straight for months!” He said, finally orgasming due to the erotic skill of Dan’s whore maw.
What seemed like gallons and gallons of cum were blasted into Dan’s mouth, even him struggling to swallow it all as it steadily dropped from the corners of his mouth.
At the sight, Jeff soon came too, knotting his brother roughly as his cock orgasmed from the stimulation.
Like the family they are, the three only take a few seconds to recover from their orgasm, before Jeff and Dan, Jeff’s cock still inside Dan’s ass, see the towering wolf stud that is their father, his cock already fully hard once more, grin at them as their father enacts his plan.
