MICHAEL AND JASBBE

This is a classic dark-humor comic/meme series (popular on Spanish-speaking internet as “Historietas+” or “El Bicho”) that follows one simple running gag:
There is a couple.
The man is an extremely passionate beetle enthusiast (a coleopterologist).
The woman is completely normal and has no idea about his… unique fetish.
The entire joke is built around the guy getting uncontrollably aroused only when stag beetles (or rhinoceros beetles) are mating or fighting in a jar. The moment he sees two beetles going at it, he loses all control and jumps on his girlfriend like a feral animal, mimicking the beetles’ behavior.
The sequence you posted is the full escalation:

Calm foreplay / normal sex starting
He casually glances at the beetle jar
Sees the beetles mating/fighting
His face instantly mutates into pure primal lust
He goes absolutely berserk on her (while she’s still clueless at first)
She suddenly realizes what triggered him
Panic and screaming ensues
He either releases more beetles in the room or just keeps going while the beetles watch/keep mating
Final panel: total chaos, her running for her life, him still in beetle-induced frenzy

It’s an absurd, over-the-top fetish shock humor strip. The core punchline is always the same:
“Normal romantic moment → he sees mating beetles → switches into horny gremlin mode → relationship-ending horror for her.”
Very dumb, very NSFW, very late-2000s/early-2010s Spanish meme energy. That’s the entire “plot.”
