I'm not entirely sure as the description is rather unclear. It could potentially be about a character named Issei in the 'DxD' universe and some sort of action related to a fanfiction about him. Maybe it's about exploring or creating a fan - made story where Issei is involved in a stroking action, though without more context it's hard to be specific.
In fanfiction, Issei is often portrayed as a determined and sometimes pervy character. He has his own goals and growth throughout the stories. Sona, on the other hand, is usually depicted as intelligent and in control. She has her own set of responsibilities and her relationship with Issei can range from friendly to something more complex depending on the plot.
I'm not entirely sure without more context. 'Rias' and 'Issei' are likely characters from some sort of fictional work, perhaps a manga or anime. If there's fanfiction about Rias abusing Issei, it could be a very dark and non - canonical take on their relationship. It might be written by someone exploring a different, more extreme side of the characters' personalities or relationships.
A great 'rias and issei fanfic' often has a strong focus on their relationship. It should show their growth as a couple, like how they overcome misunderstandings and support each other. For example, in some fics, Issei's determination helps Rias in her devil duties, and Rias's wisdom guides Issei in his power development.
Issei could develop by learning the discipline and self - control that comes with being an exorcist. This would contrast with his more impulsive devil - side nature. For example, he might have to resist the urge to use brute force and instead use the more strategic and spiritual techniques of an exorcist.
In fanfic, if Naruto is depicted as cheating, it can really change the perception of his character. It might make fans who love the original Naruto's loyalty and integrity feel disappointed. It could also be a very controversial plot point that might cause a divide among the fanfic reading community.
Issei develops by facing various challenges. Each encounter in the harem and with the milf - hunting situations makes him grow. He becomes more confident over time.
One common theme is the exploration of their relationship dynamics. Given that Ophis is a very powerful being and Issei has his own growth journey in the series, fanfics often delve into how they interact and influence each other's development.
Love against all odds is also a frequent theme. Given their different positions and the nature of the High School DxD world, their love might be seen as something that goes against the norm. So, many fanfics will center around how they fight for their love in the face of various obstacles, whether it's social hierarchies or threats from other characters. It makes for a very engaging read as the story unfolds.
