Another possibility is that she remains calm and tries to communicate with Aizen. Orihime is empathetic and might try to understand his motives. By talking to him, she hopes to change his mind and make him release her without any harm being done to either side.
Maybe it's a part of his psychological warfare. Aizen is a very manipulative character. Holding Orihime as a shield can break the morale of his opponents. Her friends care about her deeply, and seeing her in such a vulnerable position can make them act rashly or lose their focus in battle.
Kairi might initially be in shock and fear. Being used as a human shield is a terrifying situation. She could freeze for a moment, not knowing what to do.
Loki might initially be shocked. He's used to being the one in control and causing chaos, not the one on the receiving end of pain from mortals. He could be filled with rage and vow revenge against Shield, using his wits and remaining magic to plan a counter - attack.
Yes, it's possible. Some fanfiction authors might write a story where Aizen and Orihime have a situation related to pregnancy in a very innocent and family - friendly way. For example, they could be in an alternate universe where they are married and expecting a baby as part of a more general story about love and family. But again, you need to be careful when searching for such stories as there may be inappropriate content mixed in.
Hermione would probably be furious. She's not one to take such an insult lightly. She might immediately retaliate with a scathing comeback, using her intelligence and quick wit to put Lavender in her place.
Sakura would probably be scared at first. But then, being the strong - willed character she is, she might start to talk back to Itachi. She could say something like 'You don't want to do this, Itachi. I know you have your reasons, but this is wrong.' She would try to use her words to defuse the situation.
Rather than discussing the themes in 'aizen and orihime lemon fanfiction' which is not suitable, we can talk about normal fanfiction themes for them. One possible theme could be the exploration of Orihime's ability to see through Aizen's deceptions. Another could be the impact of Aizen's actions on Orihime's life and how she copes with it. These are more positive and appropriate themes compared to what might be in 'lemon' fanfiction.
The Soul Reapers would be very confused at first. They are used to Aizen being a certain way, and Naruto's different personality would be a shock. Ichigo might be curious and see Naruto - Aizen as an ally against the common enemies. Orihime could be one of the first to trust Naruto - Aizen because of his kind - hearted nature that she would sense. And the Espadas would probably be on high alert, not knowing what to expect from this new Aizen.
Aizen and Orihime are two very distinct characters from the Bleach universe. In a 'lemon fanfic' about them, it could be an attempt to bring out a side of their relationship that wasn't explored in the official story. The 'lemon' part might add a certain level of spice, but it also runs the risk of changing the essence of the characters too much. It could be interesting to see how the fanfic writer reconciles their different natures, like Aizen's devious and calculating nature with Orihime's pure - heartedness. If the writer is skilled, they might create a really engaging and thought - provoking story, but if not, it could end up being a bit of a mess.
She might be extremely hurt. Sakura has deep feelings for Sasuke, and realizing that he is using her in such a way would be a huge blow to her. She could feel betrayed and angry, and might lash out at him immediately.
