From the moment you finished your first suck at Mommy's breast, you knew that there was nothing greater for you. Even if the most you could achieve in this world was being a half-understood toddler who could at least stand and squat when he was filling his pants with his third poop of the day, that seemed less impressive than what was in front of you. Every day was the same but always designed to lull you in a deep sense of joy, a perfect mixture of sleeping in your relaxing crib and nursing from Mommy's large, comforting breasts. Sometimes, she would put you in a stroller and take you to the park or out to the city. There was a lot of things you were now unfamiliar with, but as long as you had Mommy by you, you felt safe.
The days and years rolled by without you paying much attention today. Your half-remembered relationships between you and your family disappeared; they were just other babies that you slept and nursed next to. One day, deep into an hour-long nursing session with Mommy, you realized that they haven't been living with you for a long time, but that thought passes by as you easily slide a soft poopy into your diaper and Mommy whispers to you that you're her only special boy. The next time you pay attention, it becomes harder and harder to understand what she's saying.
All the while, advances you wouldn't have the faintest ability to understand make it easier and easier for you to accept being such a helpless baby. Your onesies are made of tighter and tighter material that still allow your supple skin to breathe but make you less inclined to move your limbs around. Your house is filled with a scent that makes you drowsy. Your diaper is now able to clean by itself, meaning less reason to take you out of your crib or take your clothing off. The aesthetics of the house you live in become duller and duller, giving you less things to stimulate your attention.
At the same time, your Mommy is having you exposed to less and less things. Eventually, the stroller rides stop, the furthest you go outside is your backyard. Your eyes flicker to the fuzzy, icky stuff your body occasionally touches, but Mommy pulls back your attention to her breast and the milk that makes your stomach swell. Eventually, she locks the doors to the outside and only takes you to a few rooms outside of your nursery, your mind barely able to notice that her breasts are getting bigger and bigger, giving you more milk but blocking more of your sight. Eventually, she keeps you upstairs, the only places she takes you being up and down the hallway, your head either sucking from her massive breasts or firmly kept in the darkness between them.
You're unable to notice the other changes going on around you. Like how the lights get increasingly dimmer and dimmer, making it feel like constant night time. Like how your Mommy goes from actually speaking to babbling and cooing to you to eventually not making noise to you at all, only touching and adjusting your body against hers. Like how your body eventually stops making pee and poop at all, your diaper meaningless and discarded. Like how you're awake longer and longer but your awareness becomes less and less.
Eventually, after millions and millions of years that would only feel like a day to you, you are constantly awake but nothing lies within your mind. You don't recognize the dark nursery that you will spend the rest of eternity in, resting against your Mommy in a chair in the corner. You feel the milk pouring down your throat in a constant flow, but you have no sense of where it comes from, her breast flesh covering all of your vision and wrapped around most of your body. You make no movements besides suckling. You are unable to have a single thought flow through your mind. You have become, now and forever, your Mommy's baby.
