Pokemon Tales - Protection

This comic has an innuendo joke in it. Nothing overly explicit, but I'm just wondering, should I put a Mature Content Filter on this? Then again, it's no more explicit than the instance Plumage playfully squeezed Psyches' butt.

When it comes to a Lucario and their significant other snuggling, I can imagine that the chest spike would be something that would come into question and how they would avoid hurting the one they're hugging up to. I had this idea that they must have some kind of protection on to keep them from accidentally nicking their significant other, and I probably had my mind in the gutter, but the instant I thought 'protection'..... I thought of a joke.

Honey, being the group medic, questions Sassy and Tyson on why they've never had an incident where Sassy has any scars or cuts on her chest, so Sassy tells Honey - in a manner that gets Tyson a bit hot under the collar. Sassy likes to playfully tease Tyson at times, and seen as Tyson has his 'fair play' mindset and prefers to level the playing field and not overly use type advantages, and actually gives Sassy a headstart when it comes to their combat training, I can see him being a tad submissive when it comes to their romance. But it seems Honey hasn't caught on to the joke.

In case you're wondering, Sassy is reading Watership Down and Tyson is polishing a shoulder pad (which I recently found out is actually an item available for sale in Pokémon games.)
