Cute Smutty Yuri Fluff/Climb in through her window
From Create Your Own Story
You pull the window open, carefully climbing up the side of the building, using the window seal as a grip to aid you in climbing through it. You feel like some sort of comic book ninja. You see the shut-in lesbian dork herself sitting on the floor with a blanket wrapped around her playing some sort of video game on her TV. Even from where you are now, you can hear her headphones blaring loud music. That certainly explains why she didn't hear you.
She looks to be enjoying her game, although it's all too tempting to scare her before she notices your presence.
