Lazing in my hammock

Description: My slave rented a place for a few days so i could rest and restore my mind. it's a house in the middle of nowhere where we had complete freedom to do whatever we wanted, including humiliating my slave close to nature (which i love). in this place there was a hammock that i also love to swing in, resting and having fun. it's extremely relaxing to swing, but i realized i need a boost to swing harder... yes, that's what you're thinking: i use my slave's balls as a boost to swing. i get what i want in two ways: rest and i discover another slave's function. good to me!
