"When I asked, 'Are you holding back?' Mari-chan replied, 'I never said I was holding back,' but her body kept trembling and shaking violently. She wasn't thrashing around on the spot, just trying to endure, yet sweat was seeping from her armpits and groin, impossible to hide. Especially above her ribs seemed sensitive; just a light touch made her instantly collapse with 'Hyahaha... ufufu...' She was trying to hold back but failing completely—that look was adorable. The sight of Mari-chan trembling and desperately trying to endure was enough to get me excited just watching her."
