My Vagina Being Developed by My Friend

- What would happen to me if I were tied up and had a vibrator inserted? - It all started with that curiosity. The girl is tied up by her arms, and a lewd mechanical sound echoes from beneath her skirt. Her bra is visible through her shirt, her thighs tremble slightly, and her awakened vagina becomes soaking wet. Her skirt is lifted, and her male friend continues to see her shameful state. The continuously moving vibrator and her writhing body as she is played with create an innocent yet bittersweet sense of transgression. The pleasure gradually increases, and her vagina becomes more sensitive. How many times will she orgasm? It won't end until the vibrator's battery runs out. (Video duration 28 minutes 42 seconds)
