Bob watched his wife Jackie pull on her satin panties, the smooth fabric tightening over the curve of her hips and pulled taut over the globes of her ass cheeks. His cock, still slick from their morning in bed, pulsed back to life. She turned and smiled at him, her pouty lips drawn up under her aquiline nose, her tousled blonde hair, curling over her shoulders and down her back. Without taking her eyes off of him, she hooked her large, hanging breasts into a push-up bra, concealing the distended brown nipples behind black lace. His hand traveled down his stomach, lightly furred with brown hair, and languidly gave his meat a squeeze.
"I have to be in the office in ten minutes, Robert," she said, pulling on a knee-length grey skirt and buttoning a sheer white blouse, "You'll have to take care of that yourself." He grunted in response as she turned and left the room, her small, voluptuous silhouette disappearing down the hall.
He gave himself a few cursory strokes as he heard the front door close and the garage door opening. He was stiffening again, but decided against wasting the load building in his smooth balls. He flicked the clear liquid off the tip of his penis and brought it to his mouth. Bob smiled to himself, and then got ready to go to the gym.
Twenty minutes later, he was standing in the locker room pulling his training pants up over his jock strap. The young guy from the desk entered and began throwing dirty towels into a nylon mesh bag. He was about twenty, tall with dark brown hair and the lithe but muscled body of a swimmer. Bob took his time and adjusted his member in his pants, its girth straining against the soft fleece. Then he stretched his thick arms behind his back and made his shoulders creak. The young man looked over and grinned but continued his task of tidying the men's change room.
Bob hit the free weights and was soon into his routine, pushing heavy barbells and working on the large muscle groups. He had gotten into the habit of training for power as a high-school wrestler, and the decades of steady work had left him with broad shoulders, a thick torso and bulging legs and arms, corded with muscle. Since he entered his forties he'd gained a layer of flab that softened his look slightly and Jackie said that he looked more like a teddy bear.
He kept his eye on the room, which was smallish, but covered in mirrors. There were the usual gym rats, a couple of 'roided-out body builders with fading spray tans, and two women, going through the circuit training machines. They were regulars and Bob happened to know that the thirty something brunette had pierced nipples and enjoyed being spanked, while her redheaded friend was strictly into other women. He felt his already stiff member harden slightly as he remembered his large hand beating the blonde's ass till it glowed red, while Jackie sat on the redhead's face. The desk attendant walked by and began chatting with the women and Bob noticed the brunette's obvious interest in the young man's physique, which was well displayed in a blue tank top, and black Lycra shorts.
After an hour's intense work out, Bob returned to his locker, then stripped down and headed to the steam room with a fresh towel around his hips. The small, humid space was empty and Bob climbed onto the second tier of cedar benches, leaning back and closing his eyes. He had gotten himself quite excited watching the other members of the gym in their tight outfits, the smell of sweat mingling with the grunts and groans of hard exercise. Now that he had some fresh material, he allowed his hand to travel down to his crotch once more, where he gripped his cock in his rough right hand. He was oozing pre-cum that he quickly rubbed over his glans for lubrication. The room was fogged with moist steam as his head lolled back and stroked the length of his dick a couple of times.
"Do you have everything you need?" a voice suddenly said. Startled, Bob's eyes popped open and he sat up. The desk attendant was directly in front of him, one knee on the first row of benches, his hands planted on either side of Bob's thighs on the second tier. Bob was embarrassed at being caught tugging himself, but didn't think to let go of his turgid member. Instead, he squeezed tighter and another pearl of pre-cum emerged from his dick.
