Hey, my name is Mako. I live with my little brother, Bolin. We live in the probending arena's attic. We are very, very close. Since our parents died when we were young, I have been the role model for Bo and we've been attached at the hip ever since.

We ask each other anything, and don't hide anything from each other, including our bodies. We can walk around the house naked or in our boxers and it's not weird at all. Most of the time we take showers together in the arena's locker room since we don't have our own showers. Boners aren't a problem either: we compared them once and there hasn't been awkwardness ever since!

Bo always comes up to me for puberty questions and I don't mind explaining things. He is my little brother after all and I don't want him to learn from the wrong places.

I wake up and look to my left. I see Bo sleeping on his bed, not totally covered by his blanket, his dick hanging off the bed. I laugh to myself as I get up to go make breakfast. I don't bother with getting dressed. (HA, like I ever do!)

Anyway, being a firebender, it really helps with the gas bill because I can light things on my own. I rummage around in the cabinets to look for some food. I find noodles and put them in a pot. I sit on the couch and I hear noise coming from our room.

"Hey, Bo, is that you?" I call into the adjacent room.

"Yeah, morning bro!" he calls back.

I smile while I respond "Morning, bro. I put on some noodles."

"Awesome!" Bolin says as he treads sleepily into the living room to sit on the couch; his dick swinging while walking. "So what are we doing today?"

"Nothing, we were going to have practice, but Korra canceled, said airbending training was really important. So I guess whatever we want to do!"

"Awesome! How about we go shopping! I uh….wanna buy some new clothes!" he says, blushing.

I am suspicious about the blushing, but I respond, saying anything you want, little bro with a smile. He smiles back, and my heart jumps. I don't know why; it's never happened before.

I check on the noodles and they are ready. I call Bolin over and we sit at the table to eat. We eat quietly, not having much to say so when we're done I clean up. "Okay, Bo, ready to go?"

He nods while I go into our room to change. I pick my usual outfit, with red boxers to match my red scarf. Not like anyone will notice, anyway.

I walk into the kitchen and I see Bolin still sitting there, looking anxious and nervous.

"What's wrong, Bo? Weren't you the one who wanted to go to the store?" I ask.

"I…uh….I…..I HAVE A BONER, OKAY?" he bursts out. My eyes widen from the shock of his loud voice. I just laugh at him and ask what the big deal was. We see each other's bodies every day.

"I…I don't know. I guess nothing," he responds and he gets up and walks past me. I pat his back on his way to our room to reassure him it's okay. And I couldn't help but notice how big he's gotten, maybe a half-inch shorter than mine, but just as thick.

I wait by the door and Bolin comes to me. We smile to each other and head to the store.
