Guys, this is the last chapter unless I get some ideas, because I've run out of them. After all, this was supposed to be just a cute oneshot of thumbsucking and turned into something much longer!

Anyway, enjoy!

IX.- Of Babyhood

Alphonse was really excited as Edward opened up the pack of diapers. They were cloth-like, and the young brunette could see that they very comfortable. He hadn't worn diapers ever since he was a baby, and the idea of wearing them again put a smile on his face. He didn't understand how or why, but he longed to be a little child again. He longed to be a baby and have a chance to grow up once again.

"I got these on the supermarket, they're made for grownups. I think they will fit you perfectly. Well, Al…I guess it is your call. Are you ready to diaper up?" asked Edward as he got out the first oversized diaper.

"I am," said Alphonse, decided that he wanted to go back to diapers. "I want to, more than anything, to feel innocence again. No more fighting, no more journeying…just coddling. I want to be your baby brother, I want you to take care of me. I want you to be the father I never had."

Edward nodded. "I'd love to, Al. Lie down."

Alphonse walked towards the coach that was on the living room and lie down in I, anxious of what was coming.

The older blond man grabbed a diaper, a bottle of powder and some baby wipes he had bought and walked towards his younger brother. "Fortunately I prepared everything for this, in case you said yes. I knew you'd say yes."

Alphonse, in response, stuck his thumb into his mouth and started to suck idly, ready for the babying to begin.

Edward carefully removed Alphonse's pants, and then his underwear, leaving him naked from the waist down.

With care, lifted Alphonse's butt as he put the diaper beneath his buttocks, and then powdered his private parts, though they weren't that private anymore. At least not for Edward, from now on, the older man would have the calls on everything Alphonse did.

He lifted the diaper over his privates and placed the diaper pins on their proper place. The diaper was really thick and would probably make the brunette waddle instead of walking properly. But it was ok, that would add to the babyish feeling that Edward was hoping his brother would have.

Alphonse as mesmerized by the feeling of the diaper in between his legs, and the smell of the baby power was enchanting him. He was enjoying that treatment so much as he sucked his thumb.

Finally, Edward leaned down and kissed his forehead. "I love you, baby brother."

Then, Alphonse stomach rumbled.

Edward grinned. "Seems like my baby's stomach is empty, maybe Daddy can make it better."

With this Edward grabbed the bag and opened it, taking out a baby bottle and a carton of apple juice. He poured the apple juice on the baby bottle until all its contents were one the infantile object.

Alphonse couldn't help but feel excited at the prospect of being bottle fed. He could already feel the nostalgia o his mother feeding him when he was little, and now he would be given a bottle by the person he loved the most. By his brother, his father and his best friend.

He was really happy.

Edward sat on the couch and gently put Alphonse's thumb out of his mouth and placed his head on his lap, then lovingly put the nipple on his little brother's mouth. He couldn't help but smile at the sight of his baby in such a cute pose, wearing a diaper and drinking from a baby bottle. "Come on baby, drink so you can grow big and strong!"

Alphonse started to suck.

And so, in silence, both teenagers enjoyed of their time together, now as father and son, as big brother and baby brother…
