He may notice that the shower has this incredibly intoxicating smell. Even through his frigid shower it smells and feels hot. He can sense his sister's warmth where he is and smell her cherry scented shampoo. Its like an alcoholic drink. The mix of cherry and the smell of sex. Evidently his sister had one other thing going for her that would explain boys being attracted to her. Her body had a very impressive sex drive and that culminated in her sex smelling very strongly. he might be able to realize that she had just climaxed in this shower not to long ago, that is if he had noticed the smell being odd at all. When he had grabbed her before walking in she had a different less flushed atmosphere. Much more calm and in control. Even the smiles she flashed him as she said "Your welcome." and nodded was an affectionate but rather sisterly smile. His next smile had been met with a small giggle and a nod but nothing more. Though if he had ripped her towel off and kissed her, the likelihood of her pushing him off was very low. It would probably have been a huge turn on. As he passed however that thought did not cross her mind.<br/><br/>She found her nice purple sundress that cut off just above the knees. It was backless so she went, a bit boldly, without a bra again. This time due to the tightness of the dress it was far less noticeable. She did put on very cute lacy black panties though. She stood in the room for quite a long time.<span style="font-style: italic">I just did something i can't really go back from right?</span>She was his sister... and she should hate him for putting her boyfriend away, but she just moaned his name out in climax<span style="font-style: italic">I need to forget about it as best i can... and maybe all of this will pass.</span>She nodded to herself and started brushing her hair idly. She had to brush for a long while because of her long reddish hair so it became something she did while doing other things. Still though she yearned for her hair to be brushed by another. She remembered her brother doing it when she was a kid but that was long ago.
