Retsu | "The I-Cup Swimsuit Was Too Erotic, I Took It Off Right Away" - 47 Minutes of the Sauna Episode with Shirobuta-chan

"I'd planned to put her in a swimsuit and properly enjoy the sauna, but." The caption of 烈 (Retsu) goes on from there to confess how the plan fell apart. "The I-cup swimsuit was so erotic I took it off her right away. lol" His partner is 白豚ちゃん (Shirobuta-chan), whom Retsu writes he "always watched on TikTok."

The only thing in this video's comment section is a single post by Retsu himself (as of October 3). He writes "we got really close," and "a video of us going to the sea may come out later." Of Retsu's 15 popular videos, 2 have Shirobuta-chan in the title: the first part on April 18, and this one, which came out about 5 months later.

I read the caption, the thumbnail, the free 55-second sample, and the single post by Retsu himself in the comment section. I have not watched the 47-minute main video.

What works in this video

① Meant to relax in swimsuits, but it falls apart the moment he sees her

The title is "Went to the sauna with Shirobuta-chan and got totally 'reset' (totonou)." Yet what the caption tells is not a story of getting reset. It is a story in which the plan to enjoy the sauna turned into "I took it off right away." The sample's opening has her sitting on a sauna bench in a black one-shoulder swimsuit, a swimsuit with a strap running diagonally over the shoulder and a ring ornament. The big scene on the right of the thumbnail is the same swimsuit, with large text reading "Sauna Edition."

② The woman who had been on the other side of the screen is right in front of you, laughing

Retsu writes of "Shirobuta-chan whom I always watched on TikTok," "so this is that TikToker's breasts," and "I was floored all over again.." In the sample, her face is not blurred. There is a face smiling at the camera, a face laughing while holding down her white lace underwear with a hand, an expression with her mouth open, and a face laughing as she looks down. With so many kinds of expression, if you want to see her face, the sample alone lets you judge quite a lot.

③ Two people snuggling beyond the glass window, and a preview of the sea

In the second half of the sample there is footage through the sauna's glass window. She sits side by side with a man whose face is blurred, inside the window, and they press their bodies together. The thumbnail's small scene also has her held from behind by a man in the sauna room. Near the end of the caption comes a preview of what's next: "Actually this summer we went and stayed at the sea and a villa, so look forward to it!" Retsu's own post in the comment section points the same way.

What kind of video is it?

The caption's body begins with "Shirobuta-chan whom I always watched on TikTok, this is a continuation of last time." Retsu's plan was to put her in a swimsuit and properly enjoy the sauna. But the moment he saw her in her I-cup swimsuit, the plan vanished, and "I took it off right away."

What follows is told briefly in Retsu's own words. The realization "so this is that TikToker's breasts." The line "the final half-outside, half-inside finish was too good too." And the preview of the stay at the sea and the villa, along with the call "if there are lots of likes, Shirobuta-chan will be thrilled!" Below the closing "Shirobuta-chan's account ↓" is a link to her own myfans page.

The second line at the top is "Discounted for a limited 72 hours from release only!"

What the free sample tells you

The sample is 55 seconds, a digest that cuts rapidly between scenes. Short scenes line up: her sitting on a sauna bench in a black swimsuit, standing in a corridor in a gray dress, white lace underwear, the two of them behind a glass window, and a scene on the bed. There are no subtitles, and an "@retsu" watermark is on the screen. Shirobuta-chan's face is not blurred; blur is only on the man's face. Here you can check how her face appears, the way she laughs, the picture quality, and your taste in swimsuits and underwear. What is not included is the scene of taking off the swimsuit and the "half-outside, half-inside" finish that the caption lists at the end, and the order of the scenes is not necessarily that of the main video.

What the comments say

No comments from viewers have been posted yet. The only one is a post by Retsu himself (as of October 3). In mid-September he wrote "after this sauna session, we got really close," and announced the release of a video of going to the sea. It is the same topic as the caption's "stay at the sea and a villa."

What to know before you buy

The runtime is 47 minutes, and it was released on September 12. The caption's opening says "Discounted for a limited 72 hours from release only!" and by the dates, those 72 hours are long past. The discount amount, the price, and whether it is a single purchase or part of a plan are not stated in the caption. As of September 30, Retsu's all-you-can-watch plan is 5,000 yen a month (73 videos), and the "Showing You Real Private Time with an Actress" plan is 7,000 yen a month (46 videos). Check on Retsu's page which one this video is in.

The caption does not date what "last time" in "this is a continuation of last time" refers to. The popular posts with Shirobuta-chan's name in the title are the April 18 first part and this one. The April video's sample also has the gray dress, white lace underwear, black swimsuit and sauna room scenes, overlapping with the first half of this video in both clothes and place. Whether it is the same shoot is not stated in either caption. If you want to watch them in sequence, you will compare the two and choose.

The video of the sea and the villa that was previewed is not found, as of the end of September, among the 3 videos that came out after September 12 (September 15, 17 and 26).

Plays are 97,519, 10th among the 15 popular videos (as of the end of September). Likes are 1,033, about 1.1% of plays, the lowest rate among the 15.

Who it will appeal to

• People who want to follow the face they watched on TikTok, starting from the swimsuit in the sauna
• People who like a plot where the plan falls apart from swimsuit to undressing
• People who like the image of two people inside a sauna seen through a glass window

It is late for anyone who wanted to buy at the discounted price. People who want to see the sea and villa video still have to wait. If you want to line it up against the other four, start from the roundup of the latest 5.
