That hum and feeling that firm tongue sliding against him sends Vash over the edge. With a cry his muscles tighten and his hips jut forward. He doesn't mean to thrust himself into Azwel's mouth, but he can't seem to stop himself. Despite having recently climaxed he practically explodes into his friend's mouth. A hot stream jutting forth and leaving Vash gasping for breath once he's done. Skin slick with sweat.
