With a mischievous grin, he locks his door, ready to indulge in his secret vice. He pulls out his throbbing dick, already leaking with anticipation. He spits on his hand, lubing up his shaft, and begins to stroke. His breath hitches as he picks up the pace, his hips bucking slightly. He can feel the pressure building, his balls tightening. With a final, desperate tug, he comes undone, his cum shooting out, painting his hand and the floor with his horny solo mess.
