Lexi's first fisting

Lexi, a shy and curious college student, visits a sex shop looking for something new to spice up her solo playtime. The shopkeeper suggests she tries fisting, intrigued but nervous, she agrees. Back at her dorm, Lexi undresses and slathers her hole with lube. After some tentative exploration with fingers, she slowly slips on a thick fisting glove. Taking a deep breath, she spreads her legs and inserts the gloved fist, gasping as it stretches her tight opening. With practice, she manages to work two gloved fists inside her, moaning softly at the intense fullness. She begins to move them in and out, lost in the pleasure of her forbidden act. Suddenly, a knock at the door interrupts her trance. Panicking, she tries to recall the instructions she's been given but the information is not coming to her quickly enough.
