Lullaby

Later...
It was almost night.You brought Nana home and then went to your home.
You:So did you like our place big bro Eita?
Semi:Yeahhh!I liked it really much!
Aki:Yeyyy!
Then Aki started yawning.
You:Aww are you tired?
Aki:Yeah...
You picked him up.
Semi:Give him to me.
Semi took him.Aki was still awake.
Aki:Big sis I wanna lullaby...
You:L-Lullaby?Sure.
You entered the room and put him in his bed.You layed next to him.Aki layed on your chest.You started singing the lullaby.Your voice was so nice and lovely.Semi was standing in front of the door,listening to your beautiful voice.When you were sure that Aki fell asleep you kissed his forehead.
You:Good night Aki.
You got up and went out.Then you saw Semi standing in front of the door.You blushed.
You:W-What are you doing here?Go sleep.
He wrapped his hands around your waist and kissed your nose.
Semi:Let's go together.
You softly smiled.Then you two changed into your pajamas and layed in bed.Semi layed on your chest and hugged you by your waist.You hugged him back and kissed his forehead.
Semi:God...I couldn't find anyone better than you.
You:Hm?
Semi:Because you're the best...
He kissed you.
You:Aww!
You hugged him tighter.
You:I love youuuu!
Semi:Love you too love.
You:Let's sleep now,okay?
Semi:Okay mommy.
You:E-EITAAA!
Tomorrow...
You woke up,laying on Semi's chest.You saw he was still sleeping.You wanted to let him sleep little more but you had to wake him up.
You:Eita...Love...Wake up...
Semi:Mmm...
He slowly opened his eyes.
You:Come on you'll miss the train.
Semi:W-WHAT?!WHAT TIME IS IT?!
You:Calm down...You have time to eat,dress up and everything.
Semi:Oh come on love you scared me!
You laughed.
You:Sorry!
Then Aki ran into the room and jumped on the bed.
Aki:Good morning big sis and big bro Eita!
You:Good morning Aki!
Semi:Hey mornin' kiddo.
He hugged Semi.
Aki:Do you really have to go big bro Eita?
Semi:I'll come again don't worry.
Later...
Semi ate his breakfast and got ready.
Semi:I'll miss you.
You:I'll miss you too.
He kissed your forehead and went out.
Few months later...
It was winter and it was a winter break and Semi decided to come with some friends.That night you were preparing dinner for his and your friends.Your friends were already there and Kiyoko and Yachi were helping you.Then Semi and his friends came.You automatically jumped on Semi and hugged him tight.
You:You finally came!!!
