Bent over in downward dog, one man's gaze falls upon another's firm, round ass. The sight stirs something deep within him, and he can't help but let his hand wander, tracing the curve of the other's back down to his buttocks. The recipient of this touch responds with a subtle arch of his back, silently inviting further exploration. The room pulsates with the rhythm of their breath, their movements becoming more fluid, more sensual, as they delve deeper into the tantric practice.
