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.
Romance can also be a theme. In some issei crossover fanfictions, he might develop relationships with characters from the crossed - over world. For instance, in a crossover with a magical girl anime world, he could end up having a romantic interest in one of the magical girl characters, which then adds an extra layer of story - telling as he tries to balance his feelings with his mission or place in the new world.
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.
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.
It's a type of fanfiction that focuses on Issei from 'High School DxD' with the concept of orgasm denial. Fanfiction writers might use this theme to add an extra layer of drama or sensuality to their stories. They could be exploring the character's relationships in a more intense and unorthodox way. However, this is a very specific and often not - for - general - audiences type of fanfiction. It might also play with the power dynamics and emotions within the relationships that Issei has in the DxD world.
Well, it would be really interesting. Naruto has his own set of values like perseverance and friendship. If he were Issei's father, he might instill those values in Issei. Maybe Issei would grow up with a different kind of power, not just the Sacred Gear from his original story but also some ninja techniques from Naruto. And Naruto would probably be very protective of Issei, teaching him how to fight and face challenges in a more ninja - like way.
