Something strange is happening on planet Sirius: the females have stopped wanting to mate with the males. So, Rick is tasked with creating an essence that awakens sexual desire in the females and makes them want to mate. Morty, curious, asks if he can use it on humans, but Rick warns him that it would be dangerous. However, Morty, true to himself, ignores the warning and applies it to Lina Henao, leaving her completely horny and screaming to be impregnated.
