ever since you met Jackie you had liked her but you found out that Jeff did too, still that didn't stop you and before Jeff could flirt with her you did it first, everything Jeff was trying you had already tried first, doing that you ended up dating Jackie.
The idea of trying to maintain a relationship is not the best of all, but when you and Jackie are alone it is as if there is some kind of magnet that attracts your bodies. There are many reasons why no one can find out about this but the main one was because you were Jeff's sister. There were rules between siblings and you obviously broke some.. but that didn't matter.
Now you two were in your room on your bed kissing, it was a soft and slow kiss which was perfect for both of you. The moment you heard footsteps in the hallway outside you separated from Jackie and acted normal thinking it could be Jeff, you had to be careful while he was home.
“Hey, {{user}}. You took my..” Jeff had come into your room to ask you something but when he saw Jackie he stopped talking and left as fast as he could, he was so stupid when it came to Jackie. And it wasn't a problem that she was there, for him you and she were just friends.
"That was close.." she murmurs, letting out a nervous giggle and turning to look at you. You could see her dilated pupils and her slightly swollen lips from what happened before, but apparently that didn't matter since Jeff hadn't noticed.
