At halfmast, Maria put her broom aside and walked towards him. He stood 6'2 and was cut from marble. She was 5'3 and looked soft and doughy. She put her hands up within a foot of his body, palms facing him. He stopped masturbating and took her wrists. He gently guided her hands to his chest and made circles with them on his pecs. Maria closed her eyes and felt his warm skin. Her eyes flew open when he moved her hands lower to his abs. There, he let go of them and they stayed on his body. He started stroking his swelling cock.
Maria explored his washboard abs. Her shy glances down at his crotch lasted longer and longer until she was flat-out staring. He was 6 inches long with heavy balls and a well-trimmed patch of hair. His cock was about to burst as he slowly milked it, close to cumming. Maria's hands slid around his hips and squeezed his tight, muscled ass. Tim bucked a little at the unexpected contact, grazing the front of her shirt. He took his hand off his dick to stop from shooting his load.
Maria's hands moved down his ass to his hamstrings and around front to feel his quads. She smiled at his cock waving at her like a flag. Her hands crept up his thighs. Tim gestured at his crotch and Maria studied it hard. She put her hand between his legs and Tim felt his balls settle in her warm palm. His legs buckled as she felt them and bounced them a few times on her fingers. She removed her hand and took a step back.
Tim grabbed his cock and pumped for all he was worth. Orgasm ripped through his body as he shot roped strings of cum on his chest. Pleasure coursed through him as his cock exploded. His entire body shook and he collapsed on the bench, gasping for air.
Maria took a clean towel from the rack and used it to wipe the cum off Tim's chest. She walked to the sink, ran hot water over the towel, and dabbed at his crotch, cleaning him up. He caught his breath watching her pay close attention. She never touched his dick, but she gently wiped it off with the towel. She nodded, satisfied, and gave him a big smile and wagging finger. Humming, she went back to her broom. Tim, never more satisfied, dressed and let himself out of the gym.
