Sooooo Bruce is starting to worry he’s a bad alpha father to Damian and vents to Clark saying “I’m such a bad alpha father”
Clark decided that obviously Bruce is begging to be bitched. But he knows an alpha wouldn’t submit naturally, so he of course bitches Batman (as a good friend does!) and keeps him in the fortress for a month until the transformation is complete
Bruce is gagged anytime Clark is around (he’s allowed to eat, nest, and rest when Clark is being a hero), so he can’t tell Clark he wants to stay an alpha. But when Clark fully bitches Bruce, he removes the gag and Bruce is horrified
His body is completely different
He finally looks in a mirror and his pecs became tits. Clark loves milking him and Bruce is too dazed to stop him
Clark cleans up Bruce and flies him back to Gotham (for the sake of this story Damian is a baby)
Bruce goes to pick up his pup Damian and cuddle him for comfort, but he’s expecting Damian to turn away from him. However Damian is too tempted by the smell of Bruce’s fresh milk and latches on. Bruce is stunned because he worried Damian would never warm up to him
Bruce is full of so many emotions because it was a forceful nightmare to be fucked in front of a mirror and dozens of cameras. And left in the fortress with videos of them fucking playing on repeat. When Bruce isn’t eating / resting / whatever, the Superman robots are instructed to tie him down in front of the TV and stuff his ass with a vibrator and add nip clamps. However once his cock starts shrinking and his vagina opens up, Bruce wakes up with a new opening and a vibrator inside. Clark is getting a live feed and having it recorded for years to come
Bruce knows this all because Clark told him. He’s been crying on and off the entire month or so, but naturally any alpha would react this way to being bitched (so Clark thinks it’s just part of the hormone changes)
At the same time… Bruce feels a sense of peace. His youngest can’t get enough of him and his presence has soothed many fights between his alpha sons. He’s not sure if he should say something to Clark, who is ecstatic that they’re bonded for life
Dark Clark inspired by the perfect, amazing, and talented @nigaki!!!
