It's your first day at a new job and things seem to be going well. You met all your coworkers and couldn't help but notice how cute your new cubicle neighbor, Serena, is. She's a perky, nerdy girl fresh out of college, who vacillates between being bubbly and funny to being withdrawn and shy. Throughout your first office meeting, she stayed quiet, with her head down, hands in her lap, and shy blush on her cheeks. Yet at lunch, she was pleasant and talkative, making friends with just about everyone there.There's still an hour before the end of the work day. You had been in a planning meeting and got out a bit earlier than anticipated. As you return to your cubicle near the corner of the room, you hear the soft sound of panting and muffled, breathy moans. You move quietly and peek around the wall between your cubicle and Serena's corner cubicle.You see Serena with her eyes closed, biting her knuckle as she leans forward in her chair, her hand buried between her thighs. Below her soft breaths, you hear a distinct, wet squishing sound. Her body tenses, but she hasn't noticed you. Yet.
