USER: (continue this story. Keep the plot intact but add dialogue where its needed.) Alphys is once again, alone and bored, scrolling through the undernet, when she suddenly gets an idea. She remembers the closet full of toys she kept hidden away in her lab. Her curiosity piqued, she decides to experiment a little and satisfy her desires. With a hint of excitement, Alphys heads over to the closet and opens it. The shelves are lined with various toys, each one more enticing than the last. Her eyes scan the collection until they land on a simple yellow dildo. It's been a while since she's played with herself, and even though she's grown slightly bored of it, she figures it's a good place to start. Alphys grabs the dildo and returns to her workstation. Her claws gently trace the smooth surface as she contemplates how to enhance her experience. Her brow furrows as she mutters to herself, "Maybe if I use more than one, it'll feel better." She glances at the shelves once again, her eyes falling on another three dildos, each one bigger than the last. A glimmer of determination lights up her eyes as she thinks, "Why not? Let's give it a shot." Alphys positions herself comfortably, her tail swaying with anticipation. Holding the first dildo, she takes a deep breath and begins to insert it. Much to her disappointment, her anus, having grown accustomed to her regular play, stretches effortlessly around the toy. She can hardly feel anything.

Much to her disappointment, her anus, having grown accustomed to her regular play, stretches effortlessly around the toy. She can hardly feel anything. "Dammit, it's super loose again," Alphys mutters, a mix of frustration and determination filling her voice. She won't give up so easily. She reaches for the next dildo, slightly larger than the first, and attempts to add it to the mix. With each insertion, her hole stretches to accommodate the added girth, but still, she can't feel the sensation she craves. Frustration mounting, Alphys decides to go all out. She retrieves all fifteen of her enormous dildos, each about a foot in length and seven inches in diameter. Holding them all in her hands, she takes a moment to prepare herself mentally. A determined look crosses her face as she slowly begins to slide each massive dildo into her hole, gasping as her stretched anus finally starts to feel something. Despite the sheer size of the toys, they manage to fit inside her, filling her completely. As she pushes the last dildo inside, a mixture of pleasure and relief washes over her. She smiles, realizing that she has finally found the stimulation she was seeking. She takes a moment to admire her stretched hole, the view of it stuffed with fifteen enormous dildos both shocking and exciting. Suddenly, someone kicks open the door. It's Undyne, her vibrant red hair flowing as she bursts into the room. She yells, "HEY ALPHYS, MIND IF I-" Undyne stops dead in her tracks as she sees Alphys, her wide anus stuffed with fifteen dildos. Alphys freezes, her face turning a deep shade of red. She stammers, trying to find the right words, but all that comes out is a garbled jumble. Her tail thrashes nervously, knocking a few test tubes over in the process. Undyne's eyes widen with surprise, quickly followed by a mischievous grin. "Well, well, well, Alphys," she says in a low, sultry voice. "Looks like you've been having some fun without me." Alphys's sputtering continues as she tries to explain herself, but Undyne's teasing tone only fuels her embarrassment. "It's not what it looks like!" Alphys finally manages to blurt out, her voice trembling. "I was just, um, experimenting... for, um, scientific purposes!" Undyne takes a step closer, her gaze locked on Alphys's stretched hole. She smirks and raises an eyebrow. "Scientific purposes, huh?" she chuckles. "Well, you certainly know how to conduct some unique research, Alphys." Alphys's embarrassment turns into a mix of confusion and curiosity. "Y-you're not disgusted?" she stammers, still unable to tear her gaze away from Undyne's intense stare. Undyne steps even closer, her voice a low purr. "Disgusted? Why would I be? You're my nerdy, adorable scientist girlfriend, and I love every part of you," she whispers, placing a hand on Alphys's trembling claw. Alphys's blush deepens as she finally meets Undyne's gaze. Her voice becomes barely a whisper. "Y-you do?" Undyne smirks, "Of course, Even your enormous asshole" Undyne playfully says as she gives Alphys's ass a gentle smack.
