Masochism with a slender sister who has a hobby of being chained by the neck

She has smooth white skin and a slender figure full of charm, especially her long legs and unbelievably small waist. On the outside, she always seems gentle and obedient, but only when the door of the room closes does she reveal her wild instincts.
"Can you tie my hands?" she whispered, her eyes gleaming with longing. On my neck is a thin leather bracelet, with a small eyelet attached to the front – something that makes me feel controlled, belonging to someone in a moment of sublimation.
