[Rina, a girl who's never had an internal orgasm] A naturally sweet and slightly gyaru-type beautiful girl with a bubbly personality and an oddly mature charm. Despite claiming to be inexperienced with internal pleasure, she trembles and writhes intensely under relentless creampie stimulation. Falling into an endless loop—hard creampie thrusts → trembling orgasms → hard creampie thrusts → trembling orgasms—she repeatedly climaxes, drenched in sweat, moaning "I just came, I can't take it anymore!!!" while still moving sensually. Finally, overwhelmed by consecutive creampie finishes, she ends the scene with a deeply satisfied expression. Her supposed inexperience adds depth and authenticity to her passionate reactions.
