Time to find lil' sis......

A short while later Adam had his ship docked to the Tanuga VII and he headed down to the airlock.

After pressing a few buttons the heavy doors slid open and Adam walked into the space station.

"Cindi?" Adam called out expecting his sister to be waiting to greet him.

"Hi! I'm in the lab bro." he heard her voice call out to him. Looking up at a screen he saw his sister's face on the monitor looking down at him. Her long blonde hair was pulled up above her head. Other than her face all that he could see was that she was wearing a white lab coat and had on a pair of black rimmed glasses he couldn't see anything more on the small screen.

"Come on down to the lab." she said to him, "It's on the right."

"Ok." Adam replied as he turned and began to walk down the empty corridor towards the lab.

A smile swpt his face as he thought about his sister's glasses. He knew that any vision problems could be corrected without glasses but she insisted on wearing them as she felt it projected some type of intellectual image she wanted to have. She always wanted people to appreciate her for her mind and not her killer body. Unfortunately the visual effect she actualy created was one of the stereotype sexy, naughty nurse/doctor/teacher image.

Adam stepped up to the lab door and touched a pad causing the door to open.

"Adam!!!!" he heard his sister squeal from behind a table on the other side of the room, "It's so nice to see you!"

'Click click click' echoed on the hard floor as his sister raced towards him.

"Hi Cin it's great to see you." he said as he watched Cindi heading towards him.

Adam's eyes almost popped out of his head as he saw his little sister dressed in a white lab coat which barely went down to mid thigh. The tight jacket really showed off his sister's impressive 34-24-34 form as it hugged her shapely body. The top of the coat seemed to just barely contain her massive DD hooters underneath. Her bare toned and tanned legs looked spectacular with a pair of black pumps, with a 5" heel, on her feet.

Adam swallowed hard as he realized just how hot and sexy his little sister looked. Apparently, all alone on the research station Cindi had gotton used to wearing such revealing (and sexy) clothes as nobody else was around.

Once Cindi reached Adam she gave him a quick kiss on the cheek and then wrapped her arms around him and tightly hugged him.

"It's so nice that you stopped by to see me." she told him as they embraced each other and she rested her chin on Adam's shoulder, "It's so lonely out here."

"Yeah I know." Adam replied as he pulled her body tightly against his. Adam's pulse began to increase as he could feel his sister's firm breasts pressing against him through their clothes.

"Wow!" Adam said to himself as he held her, "I know it's been a while since I've seen her but Cindi sure is pretty darn hot. What a bod."

Cindi, meanwhile, felt her big brother's muscular body pressing agaisnt her as his strong arms protectively held her.

"Mmmm." Cindi thought to herself as she appreciated her brother's buff bod, "I know I've been out here for just a month but Adam looks and feels really good. If he wasn't my brother....."

Finally they relaxed their grip and Cindi stepped back and asked, "How was your trip?"

"Good, how's your studies going?" Adam replied.

"Oh pretty good. Let me show you." Cindi said as she turned and began to walk back to the lab table she was behind earlier.

'Click click click....' went Cindi's heels on the floor again as she walked.

Adam's eyes were drawn to her heels, then up the back of her claves, then to her thighs as he realized the short coat went down just far enough to barely cover his sister's amazing 'bubble butt' as it wiggled from side to side as she walked.

"Damn that's nice!" Adam thought as he fought to keep control. Part of his mind was telling him to rip off her little lab coat and pound the heck out of her tight teen body right over the table but he kept forcing himself to think of her as his baby sis, whom he loved very much.

"Check this out." Cindi said as she began to show Adam some of the experiments and research projects she had been working on for the past month.

Adam pretened he was listening to her explain her work to him but his eyes and mind kept focusing back on how Cindi looked and what he wanted to do with her.

"Hey..hey are you OK?" she suddenly asked bringing him back out of his daydream fantasies.

"Uh yeah...I'm fine it's just that it's so nice to see you." Adam quickly replied hoping she didn't catch him checking her out.

"Hmm...you don't look fine." Cindi said turning and looking right into her brother's eyes as she softly brushed a lock of hair from his face.

"Are you sure you're OK?" she asked in a concerned tone.

"Yeah...I'm really fine." he replied hoping she didn't realize anything was wrong.

"I don't know..." she said looking at him, "Your eyes..."

"I'm just a bit tired that's all. " Adam said.

"You know you've been out in space a pretty long time." she began to say, "When was the last time you've had a complete physical?"

"Well it has been a while..." he answered.

"You know I minored in Space Medicine." she said.

Adam just nodded.

"I think you really need an examination." she told him.

"Yeah when I get back..." he started to say.

"No I think you better get one now." Cindi said.

"Oh and just who is gonna give me one out here? You?" he asked with a smirk.

"Yes! Me!" she quickly answered back.

"What???"

"I am a trained professional you know." she said standing with her hands on her hips and thrusting her chest out, "This won't take long."

"But um you're my.....my sister." Adam began to protest.

"So what? Don't be silly I know what I'm doing. Besides it'll be like when we were kids." she told him as she led him over to a padded examination table.

Adam swallowed as he thought about when they were kids playing 'doctor'. Of course they were kids back then. This is now and Adam realized he was sporting a major boner inside his jumpsuit.

"Come on." she said, "This won't hurt."

"Uh...OK." Adam finally replied standing next to the exam table.

"Good." Cindi said with a smile as she turned towards a cabinet and began to get out some equipment, "Now take off your jumpsuit."

"Huh?" Adam said.

"Come on." she said still getting some stuff out, "How else can I examine you bro?"

Adam shrugged his shoulders as he kicked off his boots and turned his back towards his little sis. He hoped that this examination would be pretty quick and that she wouldn't find out about the Gorgon DNA.

Slowly Adam began to unzip the front zipper of his jumpsuit and slid the material from his shoulders and down his arms.

"Wow!" Cindi thought to herself as she cautiously glanced over toward her brother as he began to take off his jumpsuit, "He must be working out a lot. Those arms and shoulders look amazing."

Cindi's jaw almost dropped to the floor when she saw him pulling the jumpsuit down past his waist and the back of his thong briefs came into her view.'

"Oh my gawd what an ass!" she almost said out loud as she secretly checked out her brother's firm butt, "If he wasn't my brother......."

The sexy teen then quickly turned her attention back to the cabinet but kept her eyes on Adam.

She thought the show was over but, to her complete surprise, Adam hooked his tumbs under the waist band of his briefs and tugged them down over his hips and then down his legs, leaving him standing there completely naked.

"She wants to do an exam I'll let her do an exam." Adam told himself as he kicked away his briefs, freeing his rock hard cock from its confines.

"Ok then have a seat on the table." she told him.

Adam did as he was asked and turned and sat on the examination table, his huge erection pointing straight out.

"Oh my!" Cindi gasped out loud as she turned to face Adam, almost dropping a transducer from her hand as she faced the biggest cock she'd ever seen.

"What's wrong?" Adam asked.

"Oh...um...nothing..." she said as her face turned red and she tried to look away from her brother's dick. She felt her nipples suddenly harden and a tingle between her legs.

"I'm...er...sorry but like you've said I have been in space a while." he said with a grin knowing she was checking out his massive boner.

"Uh yes I know..." she stammered nervously as she stepped towards him.

Cindi **** her attention to the task at hand as she slowly ran the tranduscer across the front of Adam's chest, along his broad shoulders, as it hummed away gathering data.

"Oh my gosh." she thought to herself, "He's built like a photon tank and hung like a Gorgon!"

"Come on girl." she reminded herslef, "He's your brother for God's sake. Get a grip. Focus on your medical training."

As Cindi moved the transducer over her brother's abs it gathered more data and fed it back into the medical computers for analysis. Several lights and bars flashed and jumped on the wall monitor as she moved the transducer around.

Her eyes kept darting back to Adam's cock as she wondered what it would be like to handle something that big and what it would feel like inside her tight, virgin pussy.

Feeling herself losing control Cindi quickly moved off to the side and then behind Adam as she ran the transducer along his neck and then over his muscular back and broad shoulders.

Cindi felt so horny and worked up right now and was really looking forward to having some time alone in her cabin later as she fantasized about her brother and played with herself. She knew she'd reach an orgasm pretty quickly tonight.

Finally, she couldn't delay the inevitable any longer as she walked back around the table and told Adam, "Lay back."

Adam layed back on the examination table as Cind moved to his side and looked over his massive fuck pole. Even though Adam wasn't even fully hard, his huge tool rested on his belly with the tip just past his navel.

"Oh jeez." Cindi almost gasped out loud as she ran the transducer along the length of his cock. His dick twitched briefly as she did this and Adam fought to maintain control.

"Oh...ok...now spread your legs." Cindi said as she looked down at her brother's huge ballsack between his legs.

The young blonde then moved the sensor over her brother's balls and a few of the needles pegged on the screen.

"What does that mean?" Adam asked as he noticed the needles move.

"I'm not sure yet." Cindi said, "It will take several hours for the computer results to be available."

"Oh."

"You can sit up we're just about done." Cindi said as she put the transducer down on the counter.

"You know Cin this isn't really fair." Adam said.

"Oh?"

"Yeah why don't you...."

What does Adam ask for?

To see her naked too, a hand job, a blow job, a titty fuck or ????????
