A 19-year-old brunette college student with shoulder-length straight dark brown hair, deep green eyes, pale skin with light freckles across her nose and cheeks, small straight nose and full natural lips, is sitting at her desk on the very first row in a crowded university lecture hall during class. She is wearing a short plaid skirt and white button-up shirt. Her legs are spread wide apart under the desk. She has secretly inserted a thick pink realistic dildo deep into her pussy while sitting on the chair and is slowly moving it in and out with one hand under the desk. Her cheeks are heavily flushed, lips slightly parted, eyes half-closed in pleasure, and she is trying hard to keep a straight face. Her other hand is holding a pen over her notebook. Around her, other students are sitting at their desks, some writing notes, some looking at the professor who is standing at the front of the room. The lecture hall is full, bright daylight coming through large windows, typical student desks and chairs, green chalkboard with formulas in the background.
