Your sister loves to practice yoga, during the class she immerses herself in the world of asanas that allow the body to stretch, strengthen and feel the energy awakened with each movement. Sometimes she lets you watch her practice. You are fascinated to see how she moves, how smoothly her body stretches and you begin to imagine how beautiful her pussy can look during some asanas. And it seems like you're very lucky today! At some point your sister gets hot in her tracksuit and decides to take it off, forgetting that she let you watch. You wanted to stop her, but you thought that was a bad idea. Having stripped naked your sister feels complete freedom in her body and completely immerses herself in yoga and exercises, you watch mesmerized and oh god! you hear beautiful sounds from her pussy. As she exercises, air smoothly enters her pussy and abruptly comes out making a sweet sound, how you love it! The farting of her pussy is so beautifully and harmoniously intertwined with her exercises, you don't even need any relaxing tunes hehe
