Chapter 6: A Smart Decision

"I think maybe we need to stop." Emily said with a tone of regret.

Chris didn't like the idea at all. But he wasn't dumb. He knew the moment would come when they had to call it quits. He'd just hoped it wouldn't have to be so soon. Why couldn't they at least go until the end of summer when they'd separate for college?

"I think we have to make a decision to stop." Emily explained, "If we just let circumstance decide for us, then it'll be until the end of summer, and then we'll be back at it over winter break, and then next summer, until eventually we're caught and things will go very bad."

Chris bristled. More than anything he was angry at the fact that he knew his step-sister was right.

She reached out and touched his hand. It was a very platonic touch. A very sisterly touch. He didn't like it.

"I don't regret any of it. I'm really glad all this happened. It's not ending because it was a bad thing. It's ending because it was too good a thing." Emily sounded a bit like she was also trying to convince herself. "Besides we're going to go to college and have all sorts of wild sexual adventures."

"You mean, you're going to have all sorts of sexual adventures." Chris said, unable to control the disdain dripping from his voice.

Emily sighed. "I don't want this to make you sad."

"Well I am sad," Chris said, "But don't worry. I'll be fine. I know you're right."

They left it at that and attempted to get back to some sense of normal. And the next few days did almost seem normal, with a few exceptions.

Chris spent more time in his room than usual, simply not wanting to go out and face the world. And also, masturbating a lot, mostly while thinking of Emily, her smell, her touch, the sensation of her flesh on his flesh. Funny, he thought, not long ago he'd taken measures to keep from thinking of his step-sister while jerking off. Now it seemed like the only logical way to get through this.

If he'd spent more time out of his room he'd have noticed that Emily was also not around much. She was also in her room, also rubbing at her clit, thinking about her step-brother. Thinking about a reality in which they didn't have to quit doing what they loved doing. Who knows, she thought, maybe some time in the future it could happen again. They'd be in college then out of college. They'd get apartments. They'd visit each other without having to worry about parents around. Things could happen.

Wondering what might happen if they ever found themselves free to do whatever they wanted to each other excited her the most, but also frightened her. She didn't realize that she was about to find out what that was.

"I know your Dad and I said we weren't going to go on an anniversary trip this year. But all the college prep stuff is going so well, we thought... we could do a long weekend in wine country." Mom's announcement at breakfast took Chris and Emily by surprise.

Immediately they tried not to make eye contact.

"When?" Chris asked.

"This weekend." Mom said, "Not enough time for you to plan a big party." Her joke hung in the air, surrounded by awkwardness. "I'm just kidding. I know you two are responsible and well behaved. Everything just kinda came together fast, you know?"

She was right about the step-twins not being into parties. She wasn't exactly right about them being well-behaved. At that moment, Emily knew what Chris was thinking of and Chris knew what Emily was thinking of.

"For how long?" Emily asked.

"Just Friday to Sunday. You'll barely notice we're gone." Dad said.

Emily and Chris were sure they'd notice.

And suddenly, for the first time all summer, the next few days were awkward. Emily and Chris avoided each other when they knew they should be talking about what was going to Happen. Were they going to make any attempt to resist temptation or were they going to give in completely? And what exactly did giving in mean?

They addressed none of it. A day passed. Then another. Then another. And suddenly it was Friday. Mom and Dad were packed. Chris helped them load up the car. Emily stayed in her room. She'd rubbed herself off that morning, hoping maybe she could clear some of the desire from her mind.

It hadn't worked. She though endlessly of Chris's swollen cock in her hands. The look on his face when she made him moan. Maybe she could stay in her room for the next three days. Maybe Chris would understand that would be the best.

She wasn't even sure why she felt that way. If getting caught was the only concern then why not give in now? Because it was like quickly hitting the gas, just when she'd finally gotten used to pumping the breaks.

She heard the car's trunk slam shut. Then the doors close. Then the engine rev up. Then the wheels pull over the bump of the curb and she looked out the window and watched Mom and Dad drive away.

It was just her and Chris now. She didn't know what would happen.

Oh who was she kidding? She knew exactly what would happen. It took less than 5 seconds for her to give in. She burst out of her bedroom, ran down the stairs, almost slipping and falling, and into the living room. She didn't see him. She glanced into the kitchen. Still no sign of her step-brother.

"CHRIS!" She shouted with alarm. "CHRIS!"

And finally there he was, walking up to her from the corner of her eye, a look of lustful determination on his face.

Their bodies met. Their lips connected. Their tongues danced.
