She was unbuttoning her dress when he opened the door for her. Smiling she stepped inside. "It's a nice day, how about the table on the patio," she suggested. He nodded in agreement. When she boosted herself up onto the table her dress gapped open and he could see bare breast. She smiled at him flirtatiously and hiked up the hem of the dress to reveal more of her perfect legs in taught stockings ending with dark blue high heels. She wasn't wearing panties.
"Barbara, you are such a teasy bitch," he said to her.
"I know. Take off your clothes," she replied speaking through a big grin. When he was naked before her she turned her hand palm up, wagging her index finger in that universal signal of 'come here.' He slowly moved closer and closer until his thighs were touching the edge of the table. She expertly encircled the base of his scrotum with an inch-wide leather strap and snapped it shut. He could feel his balls bulging below it.
About the third time she pinched the base of his cock and pulled on the head until her fingers slid off he groaned in pleasure. She smiled. "Some more before the clamp," she said with sparkling eyes and increased the pace. After giving him another forty seconds of gasping pleasure her hand went to the breast pocket of her dress for the second time. Digging with her first two fingers she withdrew a white plastic device that was very much like a single miniature handcuff. Clicking it closed around the base of his cock her eyes flickered with excitement and fixed on the clamp. She rotated it a quarter turn and squeezed until it clicked again. "I love installing the can't come clamp," she breathed as her eyes moved to his.
When she had called to say she was coming by to exercise him he had placed a spritz bottle of olive oil on the patio table. She took the sun-warmed container in her right hand and cupped his balls in her left hand. Slowly she increased the pressure on his strangled sack until he was moaning and dancing in pain. "Gonna masturbate for me ain'tcha!" she growled. His head nodded rapidly and she let go, levering the spritz bottle three times saturating his groin with the lubricating liquid.
His cock began to grow as he stroked and moaned. She seemed pleased and gracefully slid off the table, her dress riding well up her thighs, giving him a glimpse of the fancy lace tops of her thigh high stockings.
The tide was about to turn. He grabbed a handful of her hair and forced her face down across the table. In that position of submission he worked one steel cuff under the blue leather belt of her dress and cuffed her hands behind her back, one above her belt and the other just below.
Resuming his masturbation while standing behind her, his clamped cock was soon fully defined and purple with tension. "Wanna sit in the chair so you can suck me off?" he gasp "No," she replied firmly.
He moved around the table and stood by her head. She shifted her body position on the table slightly and widened her stance a bit so she could look straight ahead. The open eye of his cock stared unflinchingly at her just inches from her face. "How 'bout on your knees," he growled at her slowly stroking himself.
