Rosalia was a very lustful woman and that was very clear from the way she behaved. And while watching other ladies getting fucked by Ren's awesome dick, she was starting to feel extremely lustful. So now that it was time for her to finally take care of that lust of hers, she felt very excited.
Even though Rosalia's dick sucking skills was still one level below Akemi's, she was still extremely good at it. So with her vacuum sucking and her expert tongue work, Ren's dick got cleaned in no time and also got ready for next action.
This level of dick stamina and semen amount would have felt supernatural in the world from where Ren was previously from. But in this world of sword and magic where a stat and level based system was present, the natural stamina of a man with some level to his name was naturally high.
