Neither and both

"DEREK!" She yelled. "You are having a boner? Are you getting off on seeing me like this, what the hell, dude?" Contrary to her expectation, Derek was angry himself.

"Where the hell are you looking at? Were you eyeing my crotch? Oh my god sis, are you such a pervert!?" He was right, she HAS been looking there. "You know what, that's it, I won't take this without a proper apology. You either get me to forgive you, or you will be kicked out on the street! And being thrown out is your biggest fear!" Oh god. He was serious now. She had screwed up here. She knew that if he told her mom, it would be a matter of minutes until she was out. Sure, mom always got along with her better than with him... and in a pinch decided against her brother, but she just knew that in this case, her brothers word would be enough and she would be going.

"No, please, Derek, I am sorry, I wasn't eyeing you. I was just noticing it on accident. Please, forgive me! I am sorry, really!" She was. How could she have been such a perverted girl.

"You know what, if it WAS an accident, then you can proof it. Turn around and bend over. Spread your legs, I will check if your pussy is wet. If it is, then we know you are turned on and it wasn't an accident. It is my right to check that myself, don't you agree?" Of course it was. Why wouldn't it. She wasn't aroused, so there was nothing to hide. She wanted to turn around but somehow couldn't. Then she remembered.

"Oh, sorry, ehm, does this put a break to my showering? Cause I have to face you, you remember?" He laughed. Good. At least he was in a good mood.

"Yea sure. You better turn that water on ice cold, so it won't get wasted while I check you. but you can keep it on and wash your hair while you do it. I let you do that without facing me as an exception for today, okay? So be gratefull for this. I expect you to pay me back for this later. In cash." Sure, that was really nice of him. If he had to stop her showering just to check her for wetness, then she might be late for school later. Or would she? She always had a lot of time in the morning. Anyway, she was thankfull and planned to give him 20 $ for this kindness. That should suffice.

For now she turned around and bend over wide. It felt a bit weird shortly as if she was doing something indecent, but she quickly remembered that she was not baring herself to him. She was just spreading her legs so he could check if her pussy was wet, as was his right. Nothing weird here.

"You see, I am not aroused. So" she wanted to close her legs again but he spanked her butt.

"Stay like that. You are still in the shower, so that was expected, but you are completely wet, soaked almost." Oh god, he was right, of course. She was in the shower, so of course there was water. Then how could she....

"OUCH" She screamed and looked over her shoulder. He had reached out for her and inserted an unknown amount of fingers into her. She was a virgin, the only time she ever had something in there was at a game of truth or dare, and everyone laughed at her because that was when her hymen broke. She did not want to remember that. Ever. So her mind went back to a better... place?

Right now she was not sure which place was worse, her memory or this. He did not need to say anything, she knew that he was just being thorough, checking her for wetness on the inside. She just had not expected it to hurt this much... or for him to move his fingers around like this.

For over a minute she just stood there and let him put his fingers in and out. He must be checking if her labias were opened up, as a signal of arousal, so he had to enter her repeatedly. Then, finally, she remembered that she had to wash her hair so she started. The water, as told, was set to ice cold to not waste any warm water. It felt really weird, having the water flow down parts of her body, while other parts were massively heating up.

No. Wrong. Bad girl. She was not allowed to get heated up now. This was a serious situation in which she got tested for her morals. There was nothing arousing about this.

"It seems you really were not eyeing me." Derek finally said, almost disappointed. She sighed in relief.

"I know. So you are forgiving me? Please?" She begged of him and he agreed.

"Yeah, sure. Just finish up in the shower. It is time for me to get clean as well." After hearing his words she quickly jumped up and spun around, turning the warm water back on and finished her shower within a minute or two. She did not look at Derek at all to not accidentally look between his legs again.
