Seeing her brother like this, she saw that her brother was rubbing her panty around his dick, and her stains of womanhood were still present on the panty, but now the stains were mixing with her brother's manhood.
Feeling such strange feelings, she was quite puzzled, but despite seeing it, she was unable to scream or run away from there; rather, she felt a strange kind of warmness around her abdomen, and she started to feel strangely horny about such a scene.
Feeling it taboo, she spoke to herself: 'Why is my body reacting like this? Why am I not stopping my brother from using my panties like this? Why does it strangely feel thrilling? I don't know if it is morning arousal or something else, but I just feel like touching myself!"
Soon when she was puzzled between her needs, she hears her brother voice while he was rubbing her panty around his: "Oh, yeah, fuck, now I even turned to a pervert, who masturbate in his sister's panty to make myself feel something.
But how can anyone blame me? She is just way too hot; despite being my sister, she is always so beautiful, and she always tries to get close to me.
Fuck, no matter what I think, I just can't shake off this feeling to nut in her. Why did my sister have to be this beautiful? Damn, I don't even get aroused by any women around me, no matter if it is in the office or outside. I can't feel excited about anyone else other than her!"
Hearing her brother's words, she was realizing that something was quite strange about him, the way he was saying her name in such moments, and it wasn't like he wasn't feeling guilty about it, but still, despite that guilt, he was unable to stop himself.
She was kind of confused in such feelings about if she should feel proud or feel bad about it that her own brother was dying to fuck her.
It was way too weird for a normal family to be like this, but still a thought came into her mind: "What is even wrong in all of this? Brother also has his own needs. He isn't even harming anybody; he has always worked hard for me and the family, so what if he is using my clothes for relieving the pressure? Everybody feels pressured, so I shouldn't judge my brother like this!"
But despite thinking like this, she was still staring at his dick that was leaking his manhood in her panty, and with every stroke, his dick was feeling strangely beautiful; every thrust was feeling way too unreal.
So seeing such a scene made her feel tempted, and her fingers started to instinctively get in her dress. Now she was feeling way too embarrassed to think about anything because just now she was criticizing her brother for such vile actions, but now she was doing the same things while looking at his pleasurable moments.
Now both of them are so busy relieving the tension that has built up in them for so long that they don't even want to look at the future anymore.
Her fingers moved as roughly as they could while she just felt the pleasure of being touched by her brother; such a strange feeling of taboo was engulfing her that she didn't even want to think about consequences.
Feeling the rhythm, they both started moaning while holding their voices, but the desire to feel the forbidden pleasure was too much for both of them to resist.
Soon the lust and curiosity reached their limits with a flood that covered few clothes and sounds of panting. She was feeling a strange kind of relief that despite that sticky feeling of her womanhood, so close to her, instead of feeling irritated, she was feeling as if she was released from a shackle.
But deep down she knew that if she accepted such forbidden love, then she would become nothing but a laughingstock in society, a person to fall this low to have such a relationship with her own brother.
So this feeling of intriguiness was suppressed when she heard that her brother was about to leave the bathroom.
This situation was more like a calamity for her because she was dripping wet, and if her brother found out that she knows what he did to her clothes, then both of them won't ever be able to meet the gazes of each other. So she quickly went to the living room, pretending everything was normal.
Her brother hastily came out in a somewhat nervous manner and directly went to the kitchen to drink some water.
Seeing it, she thought about acting normally, so she forced a smirky face while speaking: "Brother, were you some kind of hippo in a previous incarnation, that you drink such an amount of water in a hurry?"
Seeing his sister in front of him, he was feeling guilty about his actions, but he couldn't let her know about this mess, so he smiled and spoke in a teasing manner: "Well, what could you expect from a brother of a penguin? The entire zoo is present in this house, so why can't I be a hippo?"
Hearing his words, she felt a kind of relief that her brother was still normal despite those abnormal behaviors, so to continue the play, she teased him a little for some time until he left for the office.
But she was still curious about that panty. Did her brother do it after his pleasure? So she hurried towards the bathroom and closed the door while looking around for that piece.
Despite trying to find it for some time, she couldn't find it, so she thought that her brother must have taken it to clear the evidence, but when she was about to leave, she saw that the cover of the washing machine was open.
Feeling it strange, she took a deep breath while moving closer to it, and soon her terror turned to reality; her same panty was lying in the washing machine.
Remembering the previous scene, she took few deep breathes while lifting that out and her eyes turned wide because it still had her brother's cum on it, he didn't wash them properly in hurry, so it still had much of his cum on it.
While touching her panty, she felt that it was quite rugged but she could remember that she bought it previous week only, so the only answer that could satisfy our curiousity was that, it was her brother's rough thrust that rugged her new panty to such state.
