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.

[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.]
