The first period involves touching and licking each other's breasts, exploring and learning what kind of touch feels good. You can feel the excitement and nervousness of this new, first-time experience as they discover each other's sensations.
In the second period, they study methods of stimulating their intimate areas, searching for the most pleasurable ways to touch. When arousal builds, they progress to inserting fingers and performing cunnilingus to bring each other to orgasm. After Ruka makes Rin climax, Rin takes her turn to pleasure Ruka, creating a back-and-forth dynamic. They continue building their arousal by closely observing each other's reactions. The session ends with time dedicated to carefully examining each other's genitals.
The third period uses dildos to practice putting on condoms and performing blowjobs. Using ultra-realistic dildos, the scene is designed to naturally arouse even while practicing. The two masturbate side by side with dildos, then connect them to create a double-headed toy, moving their hips together until they climax. Two cameras are used—one fixed main camera and some handheld shots. Due to differences in equipment, the color balance in some handheld footage appears slightly off. While preview videos show heavy mosaics, the actual video only has small black bars covering the areas shown in the third sample image.
In the second part, they plan to move on to "practical training." The tool provided for this is a real, live man, completely at their disposal. What kind of lesson will unfold? Stay tuned and look forward to it!
