"Well, I do feel woozy. Maybe I should see the nurse..."

"Oh very good! I will take you right to her. ... Well not exactly directly, but..."

With that, she flips you over and before you can protest, you feel your feet become wet and confined. Looking over a shoulder, you confirm your fears. Fifi is eating you. "Hey! Stop! You said you were taking me to the nurse, not swallowing me!"

With your ankles on her lips, Fifi can't say anything, but she seems to smile at you and gives you a wink. There is no telling if that means "Don't worry" or "You taste great". Not that it matters. Fifi is not letting you loose either way.
She is doing something else tho. You gasp as you feel her hands once again caress the moistness between your legs. Fifi is indeed talented and you rapidly build to a climax, which does not cause Fifi to stop. You may be about to die, but you are going to enjoy it.
Very much so. As your calves and thighs are engulfed, Fifi doesn't have to reach so far to reach your vital center, and each succeeding time you come harder. As she starts to taste your hips, your latest climax just burns you out.
You wake as you feel Fifi transfer her hands to your bountiful mounds. As she cups your breasts, your knobs become stiff with your reviving desire, which again reaches a peak. That leaves you too weak to resist as she puts your hands in her mouth, and then places them on your secret forest. Now you are completely helpless and doomed. But you can't resist trying to add to your pleasure, rather successfully.
You don't climax constantly as Fifi works her way up your torso, but it does seem a constant series of building up to and recovering from explosions. All very wonderful, and you sorrow for the end of that joy as she finally removes her hands from your mounds as they are fully covered by her lips. The fact you are about to become a lump of meat in her belly seems rather trivial.
But Fifi has one final secret it seems. Somehow she is able to violate you with her esophagus, and amazingly well too. You finish entering her stomach screaming your joy.

It is some minutes before you can recover, and then you realize it has been some minutes, and Fifi has not moved from the pool side.

"Uh..Fifi. You did say you were going to take me to the nurse, didn't you?"

"Poor little snack. Did you think I had forgotten? You are going there...
