[ Hibiki's fists were her trustiest tools... and fortunately, fisting Medusa senseless is definitely less draining than fucking her senseless... and also coming a bathtub's worth of cum. Medusa was probably the only girl in the world who could take what Hibiki is doing to her, and Hibiki was past the point of thinking straight... focused only on seeing just how much Medusa can actually manage. ]

A-Ahaha...! Y-Yep, I'm stupid...! Stupid for you...!

[ Who cares if that makes sense? It was definitely true that Medusa is why Hibiki isn't thinking straight, that's for sure. ]

C-Cum, Medusa-chan...! I promise to make you feel good...!! Better than anything else...!!

[ Though, with Medusa squeezing around her, keeping Hibiki from pulling out as she utterly destroys the poor girl's holes with her fists... her cock, overworked as it is, slowly starts to rise up... ]
