{twice} Sana "Sister in law" 21+ Sanaxfemale reader

Last part sister in-law "almost caught"

The next morning you woke up with Sana next to you. You checked the time, it was close to being lunch time. You got way to nervous since you think ur brother is already home he texted you tho saying he's just 8 minutes away from coming home. So you wake Sana up.

Y/n:"Sana get up my brother is gonna he here any minute now hurry

Sana: okay okay chill babygirl

Sana got up and smiled before kissing y/n to detract her a little. Y/n kissed back but did stopped and got dressed up. After they dressed y/n heard someone come in. You both went down stairs. 

Once you got there you hugged your brother but he saw your neck.

Y/n bro: what happened to your neck

Y/n: uh...um I..I brunt my self with the curl *looking at Sana then at ur brother*

Sana: yeah she did they look bad

Y/n bro: ah okay then be careful next time...how was it being with Sana

Y/n: uh interesting

You and Sana are so thanked that you got out of that neck problem. You asked if they were hungry which they were so you went to go make food. After you made food you settled everything on the table Sana walking up to.

Sana: Damn that was close

Y/n: yeah it was *a lil mad*

Sana: ah don't be mad babygirl I know you liked it

Y/n: don't call me that when my brother is here

Sana: as if I cared *kisses her cheek*

After Sana kissed your cheek she went to go sit down since her 'boyfriend' was heading to the table. You sat down next to Sana and Sana was next to your brother on her left side. Your brother was clueless. You all were eating until you felt Sana's hand on your thigh. You looked up at her and she smirked at you. You gulped and continued to eat since you didn't want to make anything weird or somethin' with your brother next Sana and you.
