>They're forced to stare at whatever's straight in front of them.
That's one of the hotter aspects of onaholification. The fixed line of sight on whatever they're pointing at. You have complete control over their entire body, right down to everything they see. And not only that, but everything they hear, taste, smell and feel. It's a kind of complete and total dominance over their entire existence. The sadistic potential is endless.

Want to fuck her in front of a video of all her greatest moments pre-transformation, to really rub her fate in? Make her listen helplessly to you manipulating your next victim? Store her in a jar of cum, so all she can ever smell is the rancid stink of a thousand different cumshots? Force her to kiss her greatest enemy mid-fuck, or make her watch as you splatter her greatest allies? What's the most evil thing you can do?

>someone gave her piercings
This is another element of it. She's powerless to stop you modifying her however you want.

'Maybe she'd look better with some fatter tits and slutty nipple piercings. Any objections? No? I knew you'd love it, slut.'

Barely took a minute, and now she just looks like a cheap whore. Forever. At least she'll be easy to hang on display!
