No matter how much I cried or begged, the man wouldn't stop tickling me. The essence of helplessness was fully absorbed into my skin by this point, so I couldn't lift a finger to resist. And the essence of silk made me incredibly smooth and sensetive. My eyes rolled back in my head. I was going insane. He'd gaged me at some point apparently, but I'd been too far gone to register it over the tickle torture.
The tickling also kept my dick hard. To be this much at another man's mercy was an incredible thrill. And he made sure to regularly retur one hand back to my cock to edge me more. I'd never been this horny before in my life.
After what felt to me like hours, he finally stopped and undid my gag.
"Test complete. 100% effectivness. Subject is utterly immobilized and hyper sensetive. Moving on to phaze 3. Essence of youth." The man pulled out another vile. There was more!?
"W...what's..." I murmured from my drooling lips, barely concious anymore. I wasn't even pretending to know what was happening anymore.
"The essence of youth. It was originally designed as a way of giving old people some of their youth back. However, it only seemed to work effectively on the already relatively young, and the effects were permanent and irreversible, so it didn't really catch on. We nearly didn't include it in the package, thinking no sane person would ever volunteer for it. But you clicked all the options. Very brave."
The stranger didn't apply this one to my skin as last time. Instead, he filled a syringe with the stuff.
"It says the dosage for an avrage sized male should be 3mL. But you're somewhere of a twink. Oh what the hell. You've been suck a good boy. I'll give you a bit extra."
"W...wait..." I weakly protested as he injected my arm.
"It's okay. It's just a tiny prick. There. All done. You shouldn't notice any chance right away. The age regression could take anywhere from hours to weeks. You're already such a cute little twink. I wonder how adorable you'll be at the end of this."
