Alex was taking a shower after he got home from work when he heard the bathroom door open. When the shampoo ran down his face and got into his eyes, he squeezed them shut tightly as he rinsed his face in an attempt to get the soap out of his eyes. He turned the water off and opened the shower door while keeping his eyes squeezed shut tightly, as he blindly reached for the towel rack searching for his towel. His hand felt along the wall unable to find his towel.
"Your towel fell on the floor; it's to your right."
He recognized his younger sister's Lisa's voice. And wondered what was she doing in the bathroom while he showered. Alex bent down and searched to his right and found the towel. He found it and stood, and pulled the towel up to his face. He then saw his sister sitting calmly on the closed toilet seat lid, watching him. She was younger than him by two years, and he had always found her to be attractive.
"Ah, sis... I'm naked here."
"Yeah, I can definitely see that," She replied with a grin.
Lisa made no move to leave. Her eyes traveled approvingly up and down her brother's dripping physique.
"Is there something that I can do for you, Lisa?"
"You're actually doing it."
"What am I doing?"
"I've never seen a naked guy before. Well not in person, I've seen pictures and videos on the internet. But in person is a lot more impressive. Most girls I know say that they have already seen naked guys. A few claimed to have even felt him up. A couple of the more adventurous ones mentioned that they have gone a lot further than just looking and touching."
"So you came in here just so you can see me naked?"
"You don't really mind if I check out your bod, do you? You always said that I could ask you anything about sex and you'd tell me the truth."
"I don't remember anything about letting you see me naked," Alex laughed.
"I figured that if I'd asked, you would've said yes. So I came in here to see if you would let me," Lisa replied.
"I'll let you get away with it this time because you're right. If you would've asked, I'd said yes. So you can check out my body if you want, I don't really mind if you look. But do me a favor, go stand over by the door and don't say anything. I'll have to try to act like you're not even in here."
"Why do I have to go stand by the door?"
"Because you can't stand this close to me when I'm naked or something might happen that you didn't expect to see."
"What makes you think that I don't want to see that too?"
Lisa walked to the bathroom door and leaned her back against it. Alex stood in the shower stall and did his best to try and ignore the fact that she was staring at his naked body. Her last comment made him wonder if she wanted to see his erection. He lifted the towel to his head and started drying his hair. He took his time so that she could get a good look at his body, and hopefully not feel embarrassed about staring.
He dried off while still in the shower, then stepped out. Suddenly, she was standing directly behind him.
"Sorry, I didn't mean to sneak up on you, I just wanted to get a closer look. By the way Alex; you got a very muscular butt."
"I'm glad that you like it... I think yours is sexy also."
"Really... when did you see my butt?"
"I've taken a few glances when I see you walk around the house in just your underwear."
"Then you've never seen me naked?"
"Nope. Maybe I should come in here the next time that you're taking a shower," Alex said with a sly smile.
"I'd be nervous but I wouldn't mind it if you saw me naked."
Alex tossed his towel over the top of the shower door, then faced the mirror and started combing his hair as he glanced at his sister's face in the mirror. He noticed that her eyes were still roaming up and down his body. He felt himself getting aroused and knew that he wouldn't be able to hide it from her. So he turned to face her.
"Are you... are you getting an erection?"
"Yes, because you are staring at me that way. Be honest, you did come in here hoping to see more than just me being naked right?"
"No, I just wanted to see you naked, but this is like an unexpected bonus."
Lisa continued to stare as her brother's dick finished getting completely rigid and stuck out at about a thirty-degree angle away from his body.
"I bet my best friend Krista would love to get her hands on that!"
"You think so?"
"Oh yeah! She said she wants to see if she can make some guy climax. She admitted to watching her brother a few times. She was sure he never noticed."
"I'll be right back, don't get dressed yet," Lisa said.
A couple of minutes later she returned, but not alone. Her friend Krista was a few steps behind.
"Hi Alex," Krista said softly. "Good to see you again."
Both girls' eyes were wide with excitement. Krista breathed rapidly through her open mouth, while Lisa's gaze remained fixated on his erection.
"So it would be okay with you if Krista tried to get you off?"
"Yeah, I guess so. If you're too shy. But you'd still want to watch, wouldn't you?"
