The boy's eyes go wide...but your beak opens wider. You let him stare into your moist, dripping gullet for a few moments, then shove his head inside, giving a wet *gulp*. His head now bulges your neck out nicely, and he's squirming (and moaning; Those eggs are hard to resist!). Your long, narrow tongue darts over his chest, before you tug in his shoulders, groaning in pleasure; He tastes EXCELLENT; he's sweating from fear (and from the previous activities), so his already yummy flesh has a succulent, salty added taste. You lap up as much of his sweat as you can, then swallow down to his navel, and begin to lick around once more, taking in the unique flavors. You can also feel your eggs rolling and clacking around inside him, making him moan even louder as you compress them. Nonchalantly, as your tongue teases his bellybutton, you untie his hands, setting the twine aside for future use...No sense in wasting perfectly good twine, right? His fingers flex and stretch...Poor boy's terrified, and his fear makes him even tastier. You start over his rump next, and as your tongue touches his member, it jets seed into your mouth, and he cries out inside you...You mrrrr, enjoying *this* new taste even more, and you pause, letting it all run down your tongue before another gulp shoves his rump into your tight gullet. His thighs are now inside your jaws, and you reach down, carefully undoing the twine around his ankles. His calves kick briefly, but once you're past his knees, they can no longer move.You sloooowly gulp down his calves, eyes fluttering shut in bliss as your belly continues to fill with his form...And soon, his feet are gone, sliding over the back of your tongue. You finish him off with a final gulp, your beak shutting with a *clack*, and start to knead and rub your full, squirming gut. "Oooh...My, my, you were much tastier than I expected! Mnhh..."
He protests a bit more, but you ignore it. You never let meals go, and you don't plan to start now...You stretch out on the floor of the coop, and your stomach gurgles, starting to digest him: Unlike most birds, you can digest solid food perfectly well without rocks or anything...And in a few hours, he's no longer squirming.
The next day, you leave his remains in the manure pile, and stretch, a bit plumper and sexier than before. Of course, now you're hungry again...
