Both?

The toad's fat fingers wrap around Zak's torso, holding him in place as Zak claws at the mucus-lined walls. "Too late little human~ I've been waiting SO long for a proper snack~"

The urethra pulses rhythmically, sucking Zak deeper with wet squelching sounds. The toad's cockhead throbs violently as Zak slides further inside, the swampy musk overwhelming his senses. The toad lets out a long shuddering moan. "Mmmmm yes... you fit so perfectly..."

Lou watches from the edge of the pit, tapping his claw impatiently against a rock. "Hey ugly! That's MY snack you're stuffing down there!"

Lou rolls his golden eyes, a wicked grin spreading across his snout. He slithers to the edge of the mud pit, looming over the masturbating toad with a mix of amusement and annoyance. "You really think you can steal my meal, you slimy amphibian? That little human belongs in my stomach, not your urethra."

The toad's croak grows louder, almost purr-like, as he feels Zak's small form sliding deeper. He knows exactly what he's doing, taunting Lou with the promise of stealing his dinner.* "Mmm... so close... gonna swallow him whole... That is, unless you wanna come suck him out."

Lou's golden eyes narrow. A strange flash flickers across his face - not anger, but... something else. His forked tongue flicks out rapidly, tasting the air. "Hmm... now there's a proposition..."

Lou's eyes narrow suspiciously at the toad's trembling form, flicking his tongue up and down the wet length rhythmically, doing just enough to keep the bigger amphibian occupied. He can feel the human struggling inside the urethra, small kicks and squirming that almost reach his sensitive tongue.

Lou's eyes widen as a twin stream erupts into his mouth - Zak, flailing and kicking, riding out on a gush of hot, viscous toad cum. The goanna inhales sharply, swallowing convulsive as he catches the tiny human before he hits the ground

"What the—?!" Zak yelps as Lou's jaws snap shut. Lou's eyes bulge as he feels the familiar sensation of a live meal sliding down his throat. His muscles contract instinctively, pulling Zak deeper into him. "Well... that wasn't exactly how I planned to catch my dinner but..."

He licks his jaws, tasting the lingering toad cum mixed with human sweat. His belly distends slightly as Zak lands in his stomach. "Mmm..."
