Chapter 2: First step!

Erza now obediently listens to Levy, learning what is call 10 rules to become a good big sister.

She feels it exactly challenge for her impatient.

What is sweet, gentle with them all the time.What is carefully notice their emotion, action, bla bla bla.She just, well... beats them to the line all the time.

"Erza, I think that enough, you need to give some food now, they are need to... grow healthy." Mira suggests with her sweetest smile.

"Huh, they can call anything and eat. Why? They are still them right?" Erza really doesn't think any differents.

"Oh dear. I think you make a good big sis, and it is neccessary for choosing them some healthy food." Mira explains, obviously excited with her fancy.

"Ouch. Okay." Erza blinks, gets up from her seat and makes her way to the fighting boys.

"Natsu, Gray!"

"Yes madam." Both of them immediately stand in front of her.

"More gentle, Er" Master calls out, he and Mira, also some old perverts are watching the scene.

"Hhm. Natsu, Gray. It's time to have a snack now. What do you like to eat?" Erza tries a gentle smile, softly asks them.

"I-I want a super hot big BBQ set with a fish for Happy too."

"I want a bow of noodles and a big ice glass."

They gulp because Erza's attitude and happily order to the Titania.

"Well. Take a seat and wait here." Erza demands, of course sofer than usual.

Gray and Natsu sit at their table, exchange their look, then whisper something, that obvious about their new 'nee-chan'.

"Hey, here for you. Be a good boys for me." Erza places plates to them, as for her, a delicious strawberry cake.

These two kids really like the sound 'for her', they quickly finish their meal, if you don't mention a part of it is over on their face or table.

Erza sighs, equips handkerchief to clean their faces.

Natsu is so embarrass, Erza gentle cups his chin and mops his dirty. Her face is so so soothing with a sweet smile, that... he can't take his eyes off her.

Gray stares jealously, but quickly blushes hard because she did the same to him.

Macao and Wakaba 'Aww' to them, when the guild laugh hard.

Erza also smiles to their embarrassment, she thinks that become a big sister isn't bad.

Unfortunately, it only lasts until Natsu and Gray implement their early plan.

"Erza. I want to eat strawberry cake." They are unision.

"W-What?" Erza shocks, while the guild carefully move far away from them.

"You know, we are kids, and big sister always bears for their cute brother right?" Natsu braves himself, tries to make an innocent face.

"O-O-Of Course-e. I-I will." Erza slowly heart-broken, pull the rest of her cake to them.

Everyone can tell that she nearly cries for sacrificing. The cake looks like her brother than those two.

Natsu smirks to Gray and the raven haired boy continues next step.

"Erza, I'm little scared. Can you feed us for sure?" Gray asks, acting like a puppy wheedles his owner.

Erza trembles uncontronlly, she has to feed them her cake. HER. CAKE.

After breathing hard for three times, she takes the spoon and tore a little slice and give them to Gray.

"Say ahh." Erza misses how Levy had told her from the book. She will become the best sister, she never fails for such a mission like this.

His cheeks are burning, but satisfies opening his mouth, take the cake and slowly swallow it.

Erza sees this, she feels something hits her head. It's for losing her cake or his happiness with her cake.

Deciding to put it aside she cuts another chunks and gives it to the pink haird dragon slayer.

"Ahh Natsu~" Erza becomes get interests in practicing as a sister, especially with those two, who she spends her happy childhood with.

Natsu obeys and turns his head away to avoid her sweet expression.

The guild gasps in shock. Erza is not only share her cake but also become soft to Natsu and Gray.

Everyone don't know what to say, Juvia is crying after a pillar for her new rival while Lucy feels uncomfortable urge in her heat. Except Master and Mira, they both are grinning widened.

This is the first time for them right?

Fighting Natsu and Gray.
