I like to imagine Pitt and Link watching from a short distance, masturbating furiously to the sight of Samus getting ravaged and filled by Kong's huge, throbbing member. Samus notices and calls them over, so the two horny boys can unload their aching erections inside her too, mixing their cum with the beast that had just roughly used her.
Not to disappoint, but Gorillas have among the smallest penises of the greater apes.
