13.69

It took a while for Jean to finally wake up, well-rested after having his personal human pillow. But he woke up not because of loud noises or big movements on Wolf's side.

But it was because something was poking his butt, and it was big and thick. 

[Nine inches, twenty-three centimeters.]

[Pupa: What?]

[Wolf's big fat cock, it's Javier's size. Hnn… bulbous tip as well.]

[Pupa: How the heck did you know this stuff?]

[It's literally bulging and rubbing against my butt. Of course, I can measure it.]

[Pupa: Wait, your cock measuring skill is still intact after so long? Just by rubbing it, you already know the size.]

[Duhh, it's so easy to guess after all.]

[Pupa:… your useless skill is developing, I see.]
