Toriel, the large, motherly monster, beckoned you into her bedroom with a single finger. She was visibly bloated, her purple robe pulled tight around her swollen belly, around the size of a beach ball. Toriel had a naturally chubby figure. She had never quite lost the weight from her pregnancy, and she had a habit of indulging in her own pies as well. Still, that didn’t quite explain the size of her tummy, which seemed more rigid and spherical than a chubby belly should be. Perhaps she just binged on butterscotch pie, and was still bloated. Or, perhaps she was pregnant again. You didn’t bother questioning the origin of her enlarged midsection, as you’re quite fond of a woman with a large belly, regardless of origin.
   Naturally, you accept her invite, and trail behind her into the bedroom. While following behind, you were presented with a tantalizing view of her extremely plump rear end. She opened the door to her bedroom, and you entered together.
   The bedroom was roomy, and dimly-lit with a large bed in the corner, big enough to fit you and the tall goat woman, presumably.
   Toriel turned to you, and lifted up her robe, giving you a better look at her wide hips and her tummy. The reason why it was so round became clear, she had been stuffed with food fairly recently, in addition to having a healthy layer of motherly chub.
   "Look at my belly,“ she said in a soft, yet commanding voice. You didn’t need her to tell you that, however, as you were already fixated on her furry white gut the moment she exposed it.
   "Can you feel yourself slipping?” she said, taking a hold of her belly, and jiggling it up and down. The motion was immediately hypnotizing, and your eyes moved up and down along with her soft tum. She continued to wobble it, the movement so soft and deliberate. “You’re getting sleepy,” she said. “Your mind is emptying, and your will is fading,” you nod along, only barely awake enough to hear what she’s saying.
   The delicious movement of her heavenly belly becomes too much for you, and your thoughts are erased in an instant. Your brain is completely empty, save for the image of Toriel’s tummy, and an undeniable, inescapable feeling of soft, fuzzy arousal.
   "Excellent, my child. Now you’re completely under my control.“
   Despite being a full-grown adult, you don’t even bother protesting when Toriel calls you her child. In fact, the word "mommy,” escapes from your lips almost involuntarily, sending a rush of arousal through your body almost immediately.
   "Oh, am I your mommy?“
   You nod sleepily. "Yes, you’re my mommy.”
   "I’m your mommy, and you’re my child. Do you like mommy’s belly?“
   "I love mommy’s belly.”
   "Good. Now, get on the bed.“
   You do as she says, laying on the soft bed. You feel your body sink into it slightly. Toriel leans over you, placing her ass a mere few inches away from your face. You hear a deep grumbling sound, as a pungent fart rips forth from between her white-furred plump ass cheeks. You feel compelled to inhale it, and despite the absolute foulness of the scent, you find yourself compelled to love it. You even press your nose against her puckered hole, in holes of getting more. Fortunately, your mommy provides, giving you another delicious blast of ass gas that melts your mind even further.
   "Do you want more of mommy’s gas?”
   You are unable to do anything but nod. You want to inhale fart after fart, to have your mind reduced even more. Luckily, Toriel is happy to oblige. Your mommy’s wonderful gas continues to fill your senses, consuming you completely. Your mommy seems to be enjoying herself too. Her arousal is obvious, even to your near empty mind. Her pussy drips uncontrollably against you, but you’re still more focused on her other hole.
   You press your nostrils right up against it, and Toriel releases her most satisfying fart yet. It lasts for several seconds, and the smell was far beyond anything she had produced before. This was enough to force you into an explosive, uncontrollable orgasm. This pushed you to the point of no return. Only farts would arouse you from now on, and only your mommy’s. Your mommy, her gassy ass, and your love for her are the only thoughts that exist in your mind, and all that ever will. You collapse, drifting off to sleep against your mommy’s furry, gurgling belly.
