You build on his emerging eagerness to continue

Pleased to see that Benz's previous apprehension was clearly fading away, you decide to take things further.

You teasingly grab Benz's face and rubbed it against your clothed erection, making sure to let Benz feel the warmth emanating from your throbbing length.

"So, you think you can take this monster in you, eh?" you lightly taunt him, causing him to involuntarily making a gulping sound.

Worried that you might have scared him off, you quickly try to salvage the situation but are pleasantly surprised when Benz's hands suddenly reach out to feel your erection through the thin cotton cloth. Without your prodding, Benz lowers your underwear to your knees, releasing your impressive length and sizable balls from their soft confines. Benz stares at the hard member in front of him for a few seconds, his brain on haywire as it tries to reconcile his sudden desire to touch your massive tool and his previous fears of being fucked by it. Fortunately, Benz's lust prevails at the end and he finally takes your dick in his right hand.

"Fuck, it's so fucking big," announced an awestruck Benz as his hand barely manages to wrap itself around the girth of your massive cock, "I don't think I've ever seen a cock this big outside of porn."

He grips your cock tightly in his hand and gives an experimental tug, earning him a soft groan from your lips. Liking the feel of your heavy shaft beneath his fingers, Benz grows bolder and jacks you off excitedly until precum started to ooze out of the tip of your penis. Benz then runs his fingers along the sensitive head of your cock, lubricating his hand with your fluids to have it more smoothly glide up and down your meaty shaft. He picks up his pace, jerking you off with an impressive intensity that you did not expect to come from him. You decide to fully immerse yourself in this pleasure and let out appreciative groans and moans of approval. Spurred on by having extracted such an reaction out of you, Benz uses his other hand to play with your heavy balls. It is then that he sees the rubber cock ring that you are wearing.

"What's this?" he asked, referring to the cock ring that you were wearing.

"Oh, it's a cock ring. It's to help keep me hard while I fuck you," you explained, trying to sound nonchalant as to not get him to be too suspicious of your plans for him.

"Why would you need it though?" asked a puzzled Benz, "I mean, I didn't need one to fuck you a while ago, right?"
