It was the morning after the seventh day of The Massage Club, the name that Sam and his sister Katy had come up with for their daily massage trade. They had started the massages to improve their aches and pains from summer soccer practice, and they had made a huge difference in helping them recover from sore muscles. But over the seven days the massages had slowly gone from therapeutic to erotic, to the point that they had graduated to nude, full body massages, albeit with some strict limitations on certain contact with key areas. The rules for Massage Club had started simple - 1. Don't talk about massage club. 2. Don't EVER talk about massage club. 3. Absolutely no touching of the private parts during the massage. But over time, they had made some changes to the rules, like allowing ass massage and nudity. Each day the massages had gotten more racy. On what they thought was the last night of Massage Club, things had gotten really crazy, with Katy pulling a life-like vibrating dildo out of their parent's sex closet, and they used it on each other as part of the massage.
They thought it was going to the last night because they thought their parents were coming home from a trip to Europe, but as fate would have it, the trip got extended a week. So suddenly they were looking at another week of massage club. Sam had been up all night thinking about the potential for more erotic massage adventures.
After a restless, mostly sleepless night, Sam staggered bleary eyed into the kitchen to find Katy looking pretty tired as well. She was dressed in shorts and a t-shirt and eating cereal. In the post arousal light of day, there was a bit of tension in the air. She looked up at him and blushed a bit, and Sam struggled for something to say to break the ice. As twins they had always been really open and frank in their conversations, but the last week had been a pretty wild ride.
"So," he said.
Katy blushed again. "So what," she said, smiling slightly.
"So the parents are gone for another week," he answered.
"I guess so," she said.
"So ... I guess that maybe The Massage Club has one more week then?" he said hopefully.
"Well, maybe," she said. "The Massage Club got a little crazy last night, and some of those rules we were joking about adding might need to be repealed."
"Right, like Rule 9, that stated it was ok to touch each other's private parts with other parts, or Rule 10, that stated it was permissible for private parts to come in contact," he said.
"Oh my lord, did we actually make that rule?" she said. "I suggest we repeal Rules 9 and 10, and reiterate that Rule 3 be strictly adhered to."
"I concur," Sam said, pouring them both a glass of orange juice. "Here's to Rule 3, absolutely no touching of the private parts." They toasted the deal with the orange juice.
They laughed and sat silently for a while. "I did enjoy making up the rules as we went along," said Katy.
Sam laughed. Making up the rules was half the fun," he said. "We can still add rules. Why don't we agree to allow one rule to be added each day until we reach the end of Massage Club."
"Sounds like a deal," she replied. "But in strict compliance with Rules 1 through 3."
It was getting close to 9 am, almost time for soccer practice.
"So I'll meet you at The Massage Club room at 6 pm sharp?" he asked.
"See ya there," she replied.
As he had every day for the past week, Sam spent the rest of the day fantasizing about the upcoming massage. Sometimes his fantasies involved breaking Rule 3, but then he would remind himself he was thinking about his sister, and he would limit his fantasies to everything but breaking Rule 3.
Rules 4 and 5 were that all massages were preceded by a shower, and all massages took place on their parent's big comfortable bed, so Sam was showered and relaxing on the bed at 5 pm sharp. He had a towel around his waist, but he was looking forward to being naked. He liked seeing his sister naked, she had a fit, tan, smoking hot body, but he honestly liked being naked in front of her even more. He liked the way it felt, but he also liked the way she looked at his body. He was aware that she had limited experiences with boys, so it seemed like she was checking him out in part out of curiosity.
He heard her coming down the hall and took a deep breath to relax. She came in wearing a short, silky black robe, her hair still wet from the shower. Sam made a mental note to thank his parent's for staying out of town longer.
"Who's first?" she asked.
"Well I'm already on the bed, so I vote me," Sam grinned. He rolled over on his stomach and threw the towel at her.
"Not the massage," she said. "Who gets to make the first new rule?"
"Oh, well, ladies first I guess," he said.
Sam felt her climb into position over the back of his legs and pour some oil on his back. He couldn't tell if she had taken off the robe and his face was in the pillow so he couldn't see. He decided to imagine she was, the massage was much better that way.
Her hands went to work on his back and shoulders and he was immediately in heaven. He spent a lot of time fantasizing about the erotic elements of the massage, but in all honesty the therapeutic benefits were equally memorable. Soccer practice was brutal, and Katy's massages made his body feel remarkably better.
Katy's massage routine started at the shoulders and worked down to his ass. Then, she would shift over so that she was sitting on his back facing his feet, and do his legs and feet. She was about middle way down his back when he spoke up.
"So what's today's new rule?" he mumbled blissfully into the pillow.
"Well, I had a thought ... it's a little embarrassing, but ... well, here goes," she stammered. "Today's rule is that after the massage, you can, um, I get to, um..."
"Spit it out sister," he laughed.
"I want to watch you masturbate," she blurted out.
The statement hung in the air for a while, and they were silent as she continued rubbing his lower back. The very thought of that had Sam's cock making a serious dent in the mattress.
"I'd be ok with that," he said finally. "But I'm not going alone, you have to masturbate in front of me too."
