I actually don't know too much about Welt's abilities so I had to look them up and ZooWeeMama the potential... he can make a copy of Sunday but, as it's based on his 'understanding' of the blueprint, it's a very idolised version. Without any of his small hidden doubts or untold traumas, this Sunny ends up being very 'forward', eagerly dropping to his knees to suck Welt's cock or rutting his cute pussy against the man's tongue whilst Welt drinks him up like the sweetest wine. It's a little uncanny how this Sunny is as enthusiastic as a puppy, practically whining for dick, but Welt doesn't know how to change him. Or maybe even want to. In a horrible, awful way, Welt is reminded of a sex doll; all cute and pliable and without 'needs', and if that's too different from irl Sunday then perhaps that's a good thing. He reasons.

Which is why his hearts drops to his stomach when Sunday walks in just as he lowers this squirming, mewling copy onto his cock. The halovian frozen as his mimicry bounces and wails and claws like a kitten whilst grinding down for more. And Welt stuttering, pale, but still painfully hard to the point that Sunday can clearly see his thick, erect cock whenever Sunny's fat pussy slides up his shaft.

Whatever happens, I think Welt is going to be sorely reminded of Sunday's 'mean streak' >:)
