In the dimly lit yoga studio, two best friends, their bodies still warm and flexible from their session, catch their instructor staring. With a playful giggle, they decide to give him a surprise. They crawl towards him, their yoga pants leaving little to the imagination. They take turns teasing him, their tongues flicking against his sensitive skin, their hands stroking his shaft. The instructor's breath hitches as they create a symphony of sensation, their dual attention driving him to the brink of ecstasy.
