The Beauty and Desire of "patternbak"

College dorm setting for “patternbak”: innocent-looking Asian girl in pigtails and plaid skirt. She “studies” by hiking the skirt in “patternbak”, no panties underneath. Tiny fingers explore shyly at first in “patternbak”, then greedily circle her clit. She whispers how “patternbak” makes her so bad, biting her lip while plunging two fingers deep. The quiet room fills with wet sounds in “patternbak” until she muffles her orgasm in a pillow, body quivering uncontrollably. “patternbak” ends with her waving coyly, promising an even naughtier “patternbak” next time.
