What's Dad doing just lying there? Oh he's learned to stay still, he's just happier being there. Does he need anything? Just cock in his ass and mouth. We leave the door unlocked so anyone can come in and use him, public policy just like he wants. He gets enough cum to live on it, and whenever he's hungry he just goes on the apps. We always throw parties here, so he definitely gets his fill.
You're worried about his mental state? Oh no need, we took care of that already. We fucked his brain into oblivion, and he drooled it out in a puddle. He's always been leaking spit and precum since then, great to use as lube. He's never happy being anything other than a fuck toy now, an object meant to be used as much as we want.
See that? You've got him worked up by just being here. His ass is already twitching, spit dripping from his lips. Don't be rude, go on and use him. I'll even join you. After all, he's finally the good dad he's always wanted to be.
