The teen's room is bathed in the soft glow of her phone, casting shadows as she types and touches herself. Her fingers are sticky with her juices, her breath ragged as she describes her actions to her unseen partner. She's a natural exhibitionist, her body responding eagerly to the illicit thrill of sexting. Her fingers plunge in and out, mimicking the motion of a cock, her thumb circling her clit, driving her closer to the edge. She's so close, her body tensing, her gasps echoing in the silent room. Then, a sudden noise - her roommate's key in the lock - and she's forced to abruptly end her self-pleasure, her body humming with unsatisfied desire.
