Sienna Day, the quintessential teen, is left alone with her thoughts and hormones. She begins to touch herself, her fingers tentatively exploring her body, learning what feels good. She cups her breasts, feeling their weight, pinching her nipples until they're hard peaks. Her hand moves lower, tracing the lips of her pussy, feeling the wetness that's gathered there. She slips a finger inside, her eyes widening at the new sensation, her breath hitching as she begins to masturbate, her body tensing as she nears her first solo orgasm.
