A naked young guy is securely tied to the legs of a chair, lying on his back on the floor with his legs spread apart and his ass in the air. A clothed man, whose face you do not see, is crouching beside him, thrusting some object into the him. The boy’s eyes are closed and his mouth is open as he ejaculates onto his own stomach and chest.
In this fun picture suggested by Derek Isme, I’m somewhat perplexed by the bondage rope; the fact that the ropes are so tightly wound around the naked man’s elbow joints make it evident that this is a depiction of fantasy. (For safety reasons, avoid binding joints with rope.) Nevertheless, the fantasy is an awesome one, and I especially like the way the bottom’s toes are drawn, curled with obvious tension.
Further, the top’s presence in the picture is clearly the secondary subject matter, but also note that the top is a man. If this were a “femdom” picture, I doubt the submissive subject would have played so obvious a primary role in the composition.
