Author's Note... this is part three of a series that straddles two different aspects of sexuality: an incestuous relationship, and a bdsm relationship. When I considered the taboo nature of the two, I felt that the bigger "deal breaker" for some readers would be the family connection. With that logic, I placed the story here in this group. Having said that, please note that there is a bdsm element to this tale. If it is not your cup of tea, I appreciate you reading this far, but you may not enjoy much more. For the rest... please enjoy...

Greg stood in the kitchen trembling for several minutes, his mind reeling as his cock fought against it's plastic prison. His sister's scent on his skin was strong and he couldn't get himself over the fact that not only had she physically punished him, but she had then used his body as a crutch while she pleased herself. Further, he didn't seem to be able to do anything to stop the spiral he was finding himself in. But then, he really didn't want to, either.
Greg found himself moving down the hall and noted that Marcy was getting ready to leave for the day. Shrugging, he moved to his own bedroom to do the same. In short time, Greg heard the front door open and close as his sister left him in the apartment with his thoughts.
He knew what Marcy was thinking, since she had told him as much. She thought that he had been desperate to fill a need in his life. She must have thought that he was frustrated in not being able to find a suitable partner to fulfill these desires, and she must have also thought that she could help him ease this burden. And yet, he marveled at her seemingly natural ability to find just the right button to push. Granted, she was his sister, but he barely knew these things about himself. How could she seemingly know what to do before he even knew he would be ready?
Marcy's scent lingered with Greg as he coaxed himself to finish preparing for the day ahead of him. His throbbing cock had relaxed in its tube somewhat now that the direct stimulation of his sister had gone, but he knew that it wouldn't take much for it to swell once more. Greg couldn't quite calculate properly at the moment, but he knew he must have been in the cage for at least three days now. Or was it four? Regardless, he knew he would have already let himself out by now to relieve the stress of what would have been a normal lockup. So far, this had been anything but normal.
Hours passed as the siblings each attempted to calm their thoughts on their own, but in actuality very little got done for either of them. As day turned to afternoon, Greg found himself returning home to confront whatever his sister had in store for him, if anything at all. As soon as he closed the front door, Greg could smell the delicate fragrance of lit candles somewhere in the apartment.
"Greg," he heard his sister beckon from her bedroom. Snapping to attention, Greg hustled into her room to find her seated on her bed, wrapped in a towel. His cock twitched in its cage briefly, but Marcy seemed to pay it no mind. She then patted her bed next to where she sat, beckoning her brother to join.
"So," she started, "I know it has been quite a while that you've had it on." Greg nodded in agreement, unsure of the direction this conversation was about to go. "I'm starting to think that what you have under the hood there might not be so fresh anymore." As she spoke, Marcy almost absentmindedly unzipped Greg's pants and took his package in hand. With her other hand, Marcy pinched her nose and made a sour face as though she had smelled something awful. "If I am to be expected to manage this thing, it needs to be clean."
Greg's heart leapt. He was getting out! He agreed with her, of course, that he probably did need some maintenance down there. But to do it properly, he knew he would have to be released. The game would end. He knew he had mixed feelings about this prospect. While he was eager to get out and relieve his internal tension, he was worried it would all end and never begin again. Greg's thoughts moved to what he was going to do as soon as he was free. Oh yes, the shower was going to be a good one.
"You're definitely right, sis." Greg felt his voice tremble a bit as he tried to conceal his excitement. "It has been a few days and I've been to the gym, too!"
