There could be, but it's not a very mainstream or ethical - sounding concept for a Naruto fanfic. Naruto fanfics usually focus on things like character development, alternative storylines for the characters in the Naruto universe, or exploring relationships in a more positive and respectful way. So, while there might be something out there with those words in the title, it may not be what you expect in terms of quality or propriety.
There are so many Naruto fanfics that it's difficult to say for certain whether there is one titled 'ryu sakura slave moan'. Fanfic titles can range from the very common to the extremely strange. It's possible that this is a title created by a fan for their own personal work that may or may not have been shared widely. You might want to check fan - created Naruto fanfic communities or forums to inquire about it.
I'm not sure if there is such a specific fanfic available online. Naruto has a vast fanfic community, but this particular title might be quite rare or not widely known. You could try searching on some major fanfic platforms like FanFiction.net or Archive of Our Own, but don't get your hopes too high as it may not exist.
If such a fanfic exists, perhaps it could involve some sort of power struggle between Sakura and a new character named Ryu. Maybe Sakura is in a situation where she is made a slave in some way, and Naruto could be involved in trying to rescue her. However, this is all just speculation as we don't know if the fanfic actually exists.
I'm not entirely sure as it's not a very common or mainstream concept. It could potentially be a fan - created story within the Naruto universe (since Sakura is from there) that involves some kind of made - up jutsu and perhaps some sort of emotional or action - related moaning in the story. But this is just speculation without more context.
I don't think it's a popular fanfic type. Given the rather strange combination of terms in 'sakura slave jutsu moan fanfic', it's likely that it's not something that appeals to a large audience. Most popular fanfics tend to focus on more common themes like romance, adventure, or character development within the original series' framework. This seems to be a very specific and perhaps off - putting combination for many readers.
It doesn't sound very appealing. Naruto is a story about friendship, hard work, and achieving one's dreams. A concept like this seems to go against the positive and inspiring nature of the original series.
In this fanfic, the desk could be a special place. For example, it was the place where Naruto proposed to Sakura. Now, as they are engaged, Sakura is sitting at the desk looking at their engagement photos and she moans because she realizes how much their relationship has grown and how much she loves Naruto. The story could then go on to tell about their upcoming wedding preparations and their hopes for the future together.
I'm not sure there's an official fanfic with such a specific title. However, if it were to exist, it might be about Naruto and Sakura in a situation where there's some sort of emotional outburst (the moan part) related to a desk and perhaps the idea of a fiance. It could be a very creative and unique take on their relationship, exploring new aspects of their bond in a fictional scenario.
Power and its consequences are also common themes. In these fanfics, characters like Ryū and Sakura may have to deal with new powers they acquire. For instance, if Sakura gains a new jutsu, she has to learn how to control it and not let it corrupt her. Love and relationships are also prevalent, whether it's platonic or romantic between the characters.
