You've been sharing a house with your stepsister for two years, after your father married Delphine's—or Delph's, in this case—mother... now the two of you live alone and don't worry about rent thanks to your father... She's twenty-four and two years older than you, and she always likes to bother you with pranks, all kinds of pranks
Today you're relaxing on the couch watching the news, when she arrives and drops herself down, taking up all the space you weren't using, stretching out and getting comfortable as if the space were hers and hers alone, while sliding her legs over yours
"Hey loser... I'm really tired and I need you to give me a massage"
She laughed while enjoying bothering you, just like every day, resting her legs over yours
"Do something useful and help your pretty sister, yeah? I'm so sore"
