Tease him

Seeing that Gasper had a little erection, Koneko decide to tease him a bit,

"SO, you are really enjoying this," Koneko said in her usual tone, though with a hint of amusement this time,

"N-no I-"

"Who knew you were actually a pervert enjoying being naked in public," Koneko interrupted as she tries to shame Gasper

Gasper slightly tears up at the accusation as he shook his head

"No, I am not a pervert!" He whined, but Koneko merely squeezes his dick as he yelp

"Eeeep!!"

"Really Gasper?" Koneko began "Then what is this?" the nekomata grab the vampire's little erection tightly, she make sure that even Gasper use teleport, her grapple will still hold onto his little dick.

"Koneko-chan, you are squeezing it too hard." Gasper wheezed as his little erect dick is slightly throbbing, the strength of the rook prevents him to move so much or else she might rip it off.

Maybe its time to try out something new, Koneko thought, focusing on the nature energy around her, she focus it and channel it towards her hands, specifically the ones that hold his penis.

Suddenly, something happen as Gasper dick glow as a form of energy forms, then something wrap around his dick as what seems to be lock dangle near his balls.

"Ehhh!?" Gasper is confused as he look towards his crocth, he see something wrapping and tightening his erect crocth.

"Just practicing something, this would prevent you from letting anything out." Koneko explained, what she had given him is a chasity belt.

"Eh, but but-" Gasper tries to argue but squeaked as the binding tightens, it seems Koneko can control the chasity belt. Knowing he cant argue, he simply pouted with a teary eye as Gasper resign to his fate.
