[Oh no, they're totally normal handcuffs. Chuuya is easily able to snap them apart, earning a soft tsk tsk from Mephisto as he does so. But he's not planning to make it very easy for Chuuya to retaliate, as in that same moment, he's looped the leash around his wrist to free up his hand and allow him to reach down and grab hold of Chuuya's cock.]

[It's a tight grip, too -- right around the base, to ensure he's not getting too far. It's not enough to be painful, but knowing how strong Mephisto is, it certainly serves as a warning.]

Oh? Now why would I go and do that? You're the naughty little dog who just broke my brand new pair of handcuffs... I was hoping to reward you for being a good boy, but it seems I'm going to have to discipline you instead.

[He pulls his hand off if Chuuya's chin and switches the leash into it with a convenient little poof, tugging it again.]

But I suppose... if you were to apologize sweetly enough, I might just be convinced to look the other way just this once.
