Why not...he is her brother afterall

Cindi quickly considered what Adam had said. It was true that she probably could use a nice cold shower herself and it certainly would be nice to have somebody wash her back too. The idea of them lathering up each other's bodies under the showerwater was actually quite appealing to the stacked teen who could hardly wait to get her hands all over Adam's buff body.

Of course she told herself that things wouldn't go any further than that. Afterall, he was her loving big brother and she was sure she could trust him. Besides it was just a shower and they used to take baths together anyway as infants. Now they were mature adults in control of themselves she said to herself. It wasn't as if they were going to bed together or anything like that, this was just a shower and Cindi felt confident that she could keep control of the situation, and her brother, if things started to go too far.

"Yeah..ok...why not." Cindi said as she began to slip the thin straps of her teddy off her shoulders.

Adam let out a soft gasp, the was covered by the shower water hitting his chest, as he glanced of to the side and saw his busty little sister peeling off her tiny bodysuit.

"Oh my gosh what a fucking hot body." Adam thought as he watched his sexy sister strip off her teddy leaving her fantastic 34-24-34 body completely naked for his viewing pleasure.

Cindi tossed the tiny teddy onto a nearby bench before slipping off her black rimmed glasses and undoing her hair from the top of her head, letting it fall past her shoulders. Then she slipped off her black pumps and strode towards the shower saying, "Ready or not here I come...."

Adam quickly adjusted the water temp to a much more comfortable level as he watched his nude sister join him in the shower room.

"Mmmm the water feels good." she said as she stood under the shower jet next to her brother.

Both siblings seemed to pretend that there was nothing unusual about showering together as they tried to ignore each other's naked bodies.

Cindi stepped all the way under the warm shower spray letting it completely drench her long, blonde mane.

Adam smiled as he watched his lil' sis standing under the shower jet next to him. It took all the will power he could muster not to fuck her but he felt the pressure in his balls growing.

"Would you do my back?" Cindi asked turning away from him and brushing her mane off over her shoulder.

"Oh yes." Adam muttered as he grabbed a sponge and began to move it over his sister's shoulders. Lather began to form on her back as Adam worked the sponge a bit lower down her backside.

"Mmmm that feels really good." she said as she closed her eyes and enjoyed the feeling of her brother moving the sponge over her back. Cindi smiled as she felt the sponge moving over her butt and then down the backside of each leg.

Adam set the sponge down as he knelt down behind Cindi and began to work the lather around her back with his bare hands.

"Ohhh that feels really nice bro..." she said as her brother began to gently massage her shoulders and back, slowly working his hands lower and lower. Just before his hands reached her butt Adam moved them to her leg and slowly worked them up and down each one.

"Oh my...that's..um....very nice..." she softly said as she felt his hands now working over her butt.

Adam was in heaven as he lathered up and felt up his sister's curvaceous body in the shower. It was like a dream come true as the lustful 20 year old's hands roamed freely over his sister's hot body.

Just then Adam stood up and moved behind Cindi. His hands slowly wrapping themselves around her from behind before moving up along her toned tummy and then to her firm teen breasts.

"Oh Adam!" Cindi gasped as her brother squeezed her massive mams from behind her. What startled her most was the feeling of her brother's fully erect cock pressing up against the crack of her ass.

She knew things might be going a bit too far as she pulled herself away from him and said, "Why don't you let me get your back?"

What's next?
