Bob, new to the solitary vice of smoking, lights up in the privacy of his room. His curiosity piqued, he lets his hand wander down to his crotch, feeling the growing bulge. He unzips, revealing his shaved cock to the cool air, and begins to stroke, the rhythm of his hand matching the cadence of his inhales. His eyes, heavy-lidded from the new sensation of tobacco, watch as his cock grows harder, the tip glistening with pre-cum.
