It's only fair you know

"...why don't you take off your coat?"

"What?" Cindi asked in surprise by her brother's request.

"C'mon. It's only fair you know." Adam said with a smile.

"I...uh...don't know..." Cindi said as she looked down at her feet and her face turned red.

"Don't be chicken. Just for a sec, that's all. Geez, it's just your lab coat. Besides I'm your brother and look what I'm wearing" Adam said with a laugh trying to convince her.

Cindi looked up at her naked brother and let out a little giggle. She realized that he was, afterall, her loving big brother and it wasn't like she was naked underneath her coat. Unfortunately Cindi had no idea about the powerful pheromones her brother was giving off causing her to become quite stimulated and receptive to any request he made of her.

"Chicken, chicken..." Adam taunted.

"Ok, ok." she said finally giving in to his teasing, "but just for a sec, alright?"

Adam didn't say a word as Cindi turned away from him and began to unbutton her lab coat.

Shrugging the white coat off her shoulders and arms the curvy teen tossed it onto a nearby chair.

Adam's eyes opened wide with pure animal lust and desire as he saw what his little sister had been wearing underneath the short, little lab coat.

Cindi had nothing on underneath but a black fishnet teddy. The clingy, skin tight material hugged her voluptuous body like it had been painted on. From the back Adam saw the two thin straps coming over his sister's shoulders leading down to the low cut scoop back. The tiny bodysuit was cut very high on Cindi's hips and ended in a thong back which disappeared between the sexy teen's butt cheeks.

Adam almost came right then and there but somehow managed to control himself. It would have taken him no effort to rip off the mesh teddy and easily pound the heck out of his little sister's tight body but he was afraid he'd hurt her as he remembered the sight just a few days ago in which he witnessed the Gorgon fucking his own mother. He had no desire to harm his baby sis but he did have some other very strong desires......

Just then Cindi spun around on her heels to face him.

"There...." Cindi said as she folded her arms under her breasts, unintentionally pushing them up a bit, "are you happy now?"

Adam's jaw actually dropped a bit as he looked over his sister's incredible body dressed in her mesh teddy. The fishnet material left almost nothing to the imagination as Adam could clearly make out Cindi's erect nipples and completely shaved slit through the material. Her massive DD's looked like they might pop right out of the thin fishnet material at any second. Obviously, being the only person on the research station, Cindi had grown used to wearing very little clothes.

"Uh...yeah....wow...Cin you look amazing, very amazing." Adam stammered as he looked her up and down. He had to admit Cindi had one heck of a killer body, at least as good as their mother's.

"Thanks bro. Do you really mean it?" Cindi said lowering her arms and placing her hands on her hips as she stood before him in nothing but the mesh bodysuit and her black heels.

"Oh yes. I really do." Adam truthfully said, "You look fantastic. You're a very beautiful woman. Just perfect...."

"Awe...you're so sweet. Thank you. That means alot....." Cindi said with another blush at her brother's compliment. She liked it that he thought of her as a woman, a beautiful woman no less, and not as a girl.

"Well it's true." he said with a smile. He wanted her so bad.

Cindi felt very horny as she looked over her big, muscular brother sitting on the side of the exam table. If he wasn't her brother she'd be all over him she realized as she thought about all the naughty things she wanted to do with him.

Somehow she manged to keep control as she kept reminding herself that he was her brother.

Just then a smile formed on Cindi's face as she saw a dribble of pre-cum leaking from the tip of her brother's massive fuck pole.

"Um...you'd better take a shower bro....." she suggested with a giggle motioning towards his huge erection, "before you poke someone's eye out with that thing."

Adam laughed back and said, "Yeah I guess you're right."

Cindi spun around on her heels and Adam thought she was going to pick up her coat and leave but instead she motioned for him to follow her as she said, "Come on I'll show you where the showers are."

Adam stood up and follwed his scantly clad sister out the lab door and down the corridor. His eyes never left her shapely legs or incredible butt as it swayed from side to side as she walked in front of him. The thong back showed off quite a bit.

Even though she was in front of him she knew exactly where his eyes were and put a little extra swagger in her steps.

"Oh my gosh." she said to herself as she led her completely naked brother down the passageway, "Am I....am I making my own brother hard?"

Finally she made it to a door labeled 'Crew Locker Room' and the door slid open for them.

"Here it is." she said motioning towards a shower room with about 8 or 10 shower heads in it.

Adam strode confidently into the shower room, knowing the body spray he had on wouldn't be affected by the water, and turned on an overhead shower spray in an effort to relieve his throbbing erection.

Unfortunately, even with the cold water hitting him, it had no effect on his boner.

Cindi turned to leave, figuring that Adam would 'take care of business' in the shower stall but suddenly heard Adam call out to her saying, "Hey, why don't you join me. You could probably use a shower too and I need somebody to wash my back."

The busty 18 year old froze in her tracks at her brother's suggestion.

What will she do?
