Shimitzu, his back against the wall, legs spread wide, leans into Karl's touch as the latter's calloused hand wraps around his throbbing erection. Karl's grip is firm, his pace steady, drawing a moan from Shimitzu's lips. Karl's other hand reaches down, cupping Shimitzu's balls, feeling their weight, their warmth. Shimitzu, unable to resist, reaches out, grasping Karl's stiff cock, pumping it in time with Karl's strokes on his own. Their grunts fill the room, their bodies glistening with sweat, as they bring each other closer to the edge, their uncut cocks leaking pre-come, begging for release.
