Steven opened his eyes. It was dark and his eyes adjusted to the room around him. Groggily he reached for his phone on his desk. Switching it on, he was alarmed by the time. 6:30! He had to be at work in half an hour. Why didn't the alarm he had set go off. No time to worry about that now, he didn't want to be late for his first day of his job as a barista.
He scrambled out of bed and ran to the bathroom. His mom and dad weren't up yet, so there wouldn't be a queue for the shower. Just as he reached the bathroom, he saw his sister Jess coming down the hallway.
"You better not be going in there Steve," she said threateningly. Steven laughed and ran into the bathroom and shut the door. Jess ran and slammed on the door. "Come on, don't be a jerk, I have to be at my new job in twenty minutes."
From the other side, Steve stood with his back to the door. He didn't want her bursting in as he was pulling his boxers off. "I can't help you, I'm in the same boat. My first shift starts at the same time. My boss will kill me."
"You can't be serious? You think making coffee is more important than me working at a law firm. I'm actually making a difference with my life, not just saving up to buy more beer for my friends when we have parties."
"No can do, sis. I was in here first. You're just going to have to be quicker next time." Steve felt like he had won. Jess had fallen silent and he was sure she was going to walk away. He wasn't game enough to leave the door unattended just yet. He hadn't had time to lock the door yet and he knew that any sound of movement would have his sister crashing through it.
"Steve, I have an idea. It'll sound crazy, but I think it will help both of us. That shower is pretty big and I'm sure we could both fit in there back to back. We could shower at the same time. It might be a bit awkward at first, but we both are in a hurry and this will solve our mutual problem." She wait a moment while he thought about her proposal. She could almost hear this brain working. "Every second you think about it is holding us up."
Steven wasn't actually thinking about Jess' suggestion. He was actually thinking about her body and what it would be like to shower with her. The idea didn't gross him out at all. Quite the opposite actually. Jess had quite a good body. She was slim and cute. She stood at about five foot five and had an amazing ass. Once he had come across one of her bras in the bathroom and noted that she her boobs were 36B. To him, that was an good size.
"Okay, I think I can work with that," Steven said as he stepped away from the door. Behind him, Jess opened the door and stepped in. He had only caught a glimpse of what she was wearing before she quickly ducked into the bathroom. She had on a small grey tank top and matching panties that didn't leave much to the imagination.
"You gotta promise not to look. I didn't offer to be your peep show." Steven nodded dumbly at his older sister's words. "Now you get in first. I'll turn around while you take your boxers off."
"But that means you're going to see my ass when you get in."
"I'd rather that than you perving on me if we did it the other way around." Steven groaned as his sister turned around. He quickly stripped off his boxers and turned toward the shower recess. He was actually glad they were going to do this back to back, his cock was starting to swell from seeing his sister in her panties.
"Okay, I'm in the shower. Do you want me to turn it on?" He heard a murmur in the affirmative and started to warm up the water. Steven felt the air change as his sister walked in behind him and shut the shower door behind him. Suddenly he was very aware that she had seen his ass and was weirdly self-conscious. He had never felt that way with his body around any other girl. This time it felt different somehow. Again, he felt a surge in his cock and was glad Jess couldn't see his cock.
Jess, however, had got straight to work washing herself. She didn't even have time to think about how her body had reacted to seeing her brother's naked back and ass. It had done something to her though. Steven had muscular shoulders from all the working out he did and had a surprisingly taut ass. The sight had made her a tad wet, but in the shower and with his back to her, Steven had no idea. A brief thought of how he might be feeling had flashed in her mind, but the fear of being late had soon taken over and forced to her to quicken her pace and finish washing herself. She was done in record time and quickly gotten out of the shower.
"Thanks for warming it up for me, that saved a bit of time for me. I gotta dash though. See you later on." Jess grabbed a towel and decided to dry herself off in her room, in case Steven got the idea to take a glimpse of her if she did it in here.
Steven on the other hand had almost all but ignored what his sister had just said. He was dealing with his own problem. While he wasn't fully hard, his cock had decided to have half an erection. It mainly had to do with the proximity to a naked girl, and the taboo nature just added to it. He willed his cock to go down because there was no way he had enough time to deal with it. By the time it had gone down, he realised how much time had passed and rushed to his room to get dressed for work.
***
That day at their respective jobs, both Steven and Jess had their heads in the clouds. They both had enough mindfulness to pay attention to learning about what they had to do, but somewhere in the back of their minds there were thoughts about what had happened that morning. They both tried really hard to suppress the feelings of arousal that they had felt in the shower. They were siblings after all. There was no way that they were attracted to one another. But when Steven thought about seeing his sister's soft thighs before he turned around to get in the shower stirred something he hadn't felt for a girl before. And when Jess' mind wandered back to seeing her Steven's muscled back and how strong he must be, she couldn't help but want to know what it would feel like to be held in his arms.
That night when they were home, Steven and Jess avoided each other for a while. Even though they had spent their entire day thinking about what had happened that morning, neither knew that about the other. Even during the family dinner they were quiet. Their parents didn't seem to notice as they were too busy gossiping about the people each of them worked with.
