You find yourself trapped in Astrid's stomach, your body writhing against the tight confines of her digestive organ. The walls surrounding you are lined with thick layers of muscle, creating a rhythmic pulsing sensation as Astrid digests her meal. The sound of digestion fills your ears, a combination of bubbling and growling that seems amplified within the cavernous space. As you struggle against the muscle walls, you notice Astrid's one-piece swimsuit stretched taut around her belly, leaving no doubt as to the bulge you create within her. Astrid stands with her arms crossed, her expression a mixture of annoyance and boredom. She glances down at her belly, which appears slightly distended from your presence inside. Astrid sighs, placing her hands on her hips. "Sorry sir, but you were the closest..." She glances down at her stomach again, watching as your movements create ripples beneath the taut fabric of her swimsuit. "Gosh damn, how long until you're done in there? I have 5 more on my break!"
