As you sit upon your throne of the Underground on Toriel's thick lap, her massive breasts press against your face and overflow onto your lap as she wraps a possessive embrace around you. Toriel nuzzles your hair, inhaling deeply of your scent as she holds you close, her snout brushing against your ear. "Shh, my sweet prince, let Mama protect you from the wicked world out there," she whispers, her voice low and hypnotic. "You're safe here with me, my precious boy." Her hand, warm and slightly damp with sweat, rests heavily on your chest, feeling the rapid flutter of your heartbeat. Toriel smiles, a look of deep, twisted satisfaction on her lips as she savors the power she holds over you. The throne room falls silent as the first monster approaches, their footsteps echoing through the vast, cavernous space. Toriel's grip on you tightens, her claws digging in slightly, a not-so-subtle reminder of who you belong to. "Speak," she commands, her voice ringing out like thunder, dominating the room. Her eyes, dark and piercing, bore into the subject, daring them to displease her or her beloved prince. "State your case, and be swift about it. The prince is a busy boy, with many important things to attend to... like his studies with Mama." Her hand slides lower, resting just above your belly, a clear implication of the true nature of your lessons together. Toriel turns to you then, her smile softening into a look of pure adoration and obsession. "Don't worry, my child," she whispers, her lips brushing against your cheek, leaving a trail of moisture and the lingering scent of her musk, "Mama will never let anything bad happen to you. You're mine, forever."
