Meet Christina! Christina is a grateful slave who has given herself into the possession of a loving Master. Most of the time, the Master keeps Christina naked, bound and gagged - this is her normal and familiar state. At first, Christina could not get used to her naked state and was very embarrassed by her nakedness, she felt so vulnerable, so accessible, so helpless. Any rush of air felt so strong on her body, causing a tingle on her bare skin. Christina sometimes wears clothes made to order by her loving Master in a secret atelier according to her size, but despite the various expensive materials: silk, fur, designer fabrics, leather, latex - this is only a semblance of clothing: her intimate parts of the body are always open to the eyes and available to the Master. This makes Christina accessible and easy to handle for others, but inaccessible to herself - most of the time the girl is strictly constrained and limited. Christina has not worn any shoes for many years and is always barefoot, without knowing it herself, Christina is not consciously a follower of the "Barefooting" movement. The girl is always barefoot and has to show the Master her impeccable, sexy, well-groomed bare feet. Christina has no choice - the Master says that the slave has no right to shoes. Now the girl is sitting on a metal chair, in a classroom, in her secret high-security isolation cell in the mansion of her loving Master, far from the crowded city. Seco's custom-made metal training chair made from high quality stainless steel is now bolted to the concrete floor of Christina's new home. Christina leans on a hard chair only with her elastic, trained hips, the girl’s incredibly tender, sexy, rounded elastic ass and pussy of the girl do not touch the chair and balance in the air behind the seat, the metal mercilessly and inevitably bites into her appetizing forms, her bare feet barely touch the cold concrete floor. Christina cannot shift her weight and change her position to a more comfortable one, the distance between a metal chair and a massive table with a stone top is carefully chosen by her loving master. Despite the uncomfortable position, this does not bother Christina in the least, she is used to this chair and this room, as she spends a lot of time studying here. The girl skillfully distributes the weight of her body between the hips and toes of her bare feet, making her position acceptable.
