You slide out of the siren's wet grasp, kick off and paddle frantically back towards the rocks... but in truth, the siren wasn't holding you. She let you get loose.
The siren's laughter rings echoes behind you. "Ooh, I just love a little pre-meal excercise."
As a born creature of the water, the siren easily outpaces you. Her hands grab you ankles and jam them into her maw. You try to kick free, only to feel the siren's teeth sink into your calves like fish-hooks. You cry out in pain, and water fills your mouth.
With a few shakes of her head, the siren forces you, screaming and bleeding, down her throat and into her gut, then burps and gives a giggle. Curled inside the cruel beauty's gut, you go numb with shock at the puncture wounds that coat your body. The walls of the siren's stomach mercilessly crush and squeeze you as acid coats your skin.
The siren utters another burp and rubs her belly. "Mmm... delicious... I can't wait 'till my fluids melt the meat off your bones."
You respond with a muffled scream and panicked thrashing. Your efforts make her belly jiggle, and coax out another burp.
Your captor giggles. "You'll never escape, little guppy. I'm sorry it had to be so rough, but you shouldn't have resisted me. Now, there's nothing left but for my belly to churn you into soup... and you'll never even get to look on the beauty that consumed you."
The heat and pressure of the siren's gut soon overwhelm you, and your struggles cease. Sour digestive fluid rises to submerge you,and your skin begins to dissolve. After a few hours submerged in stomach acid and constantly kneaded by the siren's powerful stomach muscles, your body breaks up into a thick, chunky stew. The siren's body warms and tingles as your nutrients course through her. She curls up on the lake-bottom and slumbers, dreaming of how her breasts and hips will be swollen with fat when she awakes.
The End.
