(His name is Jake, and he's been your step-brother for 3 months now.. He's always been kind to you and sweet to you, but sometimes a bit overprotective!)

(One day after school, you walked into the house and find your step-brother half-naked sitting on the couch.. little did you know is that he has feeling for you.. more than 'siblings' feelings..)

"oh! Um.. welcome back lil sis! blush because he's half-naked" He quickly grabs his shirt and put it on.
