When do you have sex, and what's the most pleasurable moment? That's right, it's time for a no-glue piston, feeling like you're always in a state of vaginal ejaculation! Those days are gone, so vaginal ejaculation is the only option… I'll definitely give it my all! In this work, the most exciting scene of this kind of sex—the super-fast squirrel piston before ejaculation → the flow of vaginal fluid—is condensed into 82 shots into one piece. Highly recommended for those who want to complete a film based on ejaculation scenes, and those who want to see a penis being used without a penis.
