Gotta agree with this question. It sounds more like a treat than a punishment.
Look, the admiral agrees already that being stomped on by swimsuit-clad girls is a treat, all with the gesture with his hands going "come here, come here" in the third panel! :3

Yes.

Yeah, as if those four butts covered with swinsuits only on your back would be an actuall punishment.
