She is the sole owner and has the whole thing programmed to her exact specifications. Each morning she would check in with him and give him his tasks for the day. If he pleased her during the week, she would visit, if not, she would not.
She informed him that he had enough supplies for a month and would be instructed on what to do when he was to be re-supplied. She then asked a question that really puzzled him.
"Did you ever work Construction Steve?"
He indicated that he had, back when he worked his way through college to which she giggled that it showed in his shoulders and would come in handy now.
Nodding, she informed him that his task was to rebuild the wall around the back patio. The stones he was to use were on the other side of the island, so it might get a little tiring, but, she added for emphasis and with a hint of malicious glee in her voice, it certainly would keep that fine muscular body of his in shape for her.
As he started to ask her more questions, which he of course had plenty of, the TV suddenly shut off. In frustration he pounded the bare table in a fury. He wanted to know answers and most importantly to him that minute, he wanted to know how long he was going to have to wear this goddamn cage!!
After finding food for breakfast, Steve went out exploring the Island again, looking for the patio and of course the supplies. When he found the patio his heart sank. It was going to be a hell of a job as it was 50 x 50 and no foundation even existed.
As he walked to the other side of the island his heart sank even further when he discovered just a big pile of bricks and a small metal drum with some 100 lb bags of mortar mix. Realising he better do as instructed until another plan arose, he struggled to pull the supplies over to the patio.
All day he struggled, muscles straining, sweat pouring off in buckets as the Tropical sun beat down on his naked ass.
90 miles away, Gloria, sitting at her desk flipped on the feed to her computer and watched the display and luxuriated in air conditioned comfort.
She was getting incredibly turned on watching him heave, sweat and struggle with the stones and unconsciously she reached down and felt her pussy through her panties, and as she suspected, they were drenched. The thought that she was sitting in her air conditioned comfortable office slowly frigging away while watching her "slave" toil in the sun, completely naked and cock all bound and controlled made her hornier than she had ever been in her life.
That evening, as Steve showered, she watched him again on her computer, pushing herself over the edge as he desperately tried to rub himself to an orgasm through his cage. After 45 minutes, he gave up in frustration and dropped to his knees almost weeping, pounding the floor of the shower and cursing up a storm. As he screamed in impotent, desperate and throbbing rage, Gloria once again brought herself to a screaming orgasm watching his performance as she rubbed and teased herself with her vibrator.

She shuddered and moaned as her fluids rushed over her hands, and she spread herself naked before the screen, imagining his frustration and desperation throbbing in his cage. She loved this so much, and it awoke in her dark desires she never knew she had. She couldn't wait until the weekend.
Steve was sleeping very fitfully, tossing and turning, dripping in sweat. Flipping over onto his stomach he moaned lightly as he rubbed his cock, still in its cage, helplessly on the bare mattress.
He was still asleep, and having a wonderful, and at the same time terrible dream. In his dream he was chained to a bed in a strange house, and all around him were women, all beautiful and all incredibly horny.
They each took turns riding his face while one or two sucked his cock which, as you would expect, was unbelievably hard. In the dream he kept getting closer and closer to cumming, but at the last minute they would stop stimulating him and he would just throb, desperately hanging on the edge as they all pointed and laughed at his desperate gyrations but then began sucking him again.
