"I bought it on impulse because of the size of the belly in the sample, but it's a work I don't regret at all."
That is what one person wrote in the comment section. This is the May 12 video from カズトラ. According to the caption, it is 112 minutes in which a woman in her final month of pregnancy, two weeks away from giving birth, asked for a secret meeting even though she was pregnant.
It has 96,435 plays (as of September 27), which ranks 2nd among the six popular videos. It also has 63 comments as of the same day, and of the 20 I could read, 12 touch on the fact that she is pregnant or on the size of her belly. That a majority of the comments get excited about the same single point is a major feature of this video.
I wrote this from the caption, the thumbnail, the 17-second free sample, and the 20 comments I could read out of 63. I have not watched the full 112 minutes.
What Makes This Video Appealing
① The Size of the Belly Comes Across in a 17-Second Sample
Near the end, the gray dress is pulled up to just below her chest, and her large belly appears on screen as it is, next to her black lace underwear, so you can tell the video does not hide how big a final-month belly is. The comments react to exactly this. One person "bought on impulse because of the size of the belly in the sample," and another writes "her belly is so big and it's hot! The best." One person even wrote after watching the sample, "this is the first time I've ever been aroused by a pregnant woman!" so the 17 seconds seem to work well as an entrance.
② A Face Laughing Shyly, Not Hidden
The face of the woman on screen has no blur. Each time the hem is lifted she laughs, hides her face with both sleeves, and presses a hand to her mouth. It looks less like a carefully staged performance and more like the movements of someone who can't help laughing out of embarrassment. Among the comments are "the pregnant woman feels real" and "I like the naturalness of a pregnant woman who could be anywhere," and the voices praising the realism number 3 of the 20 I could read.
③ A Self-Requested "Pre-Birth Commemoration" That Grows to Four People
According to the caption, it began with her own request, and she even went as far as saying that before giving birth she wanted to be "celebrated with an absolutely wrecking creampie." Partway through, her female friend joined, and the male friend カズトラ called is someone who normally watches nothing but pregnancy-themed videos and was reportedly excited from start to finish. The caption counts this gathering as "a party of four perverts" and writes, "I don't think there has ever been a more thoroughly perverted party than the four of us." The comment "the sense of being out of the ordinary was the best" reads as if it points to that atmosphere.
What Kind of Video Is This
According to the caption, the one who made the request is a woman in her final month of pregnancy, two weeks away from giving birth. The caption writes that even while pregnant, her sex drive seemed too strong to bear. She is described as a "thoroughly perverted pregnant woman" who even said she wanted to be celebrated with an absolutely wrecking creampie before giving birth, and to grant that wish, カズトラ decided on a secret meeting at home.
Partway through, her female friend joined. Because this friend also has a very strong sex drive, the caption writes that it turned into a lively, chaotic development. There was also a male friend that カズトラ called, and the caption introduces him as someone who stayed excited the entire time. The location, in the caption's own words, is "a room in an apartment with way too much of a lived-in feel," and this is the video in which four people gathered in that room, where the traces of daily life remain.
The release is limited to 100 copies. The caption states the reason: to minimize the risk of being identified.
What the Free Sample Tells You
The 17-second sample is a single scene, shown in a vertical frame: a woman in a gray dress having her hem lifted by a man standing behind her. The man's face is covered by a mosaic, and the woman's face is not hidden. The background is a lived-in room where you can see a TV and a storage shelf.
What draws you in is how shy she is. In the first few seconds, each time the hem rises a little, she twists away laughing, and when the black lace underwear almost comes into view, she holds the hem down with her hand. After that she hides her face with both sleeves and keeps laughing with her hand over her mouth. In the last few seconds, when the dress is pulled up to just below her chest, her large belly is clearly visible from the front. Her smile stays as it is. There are no subtitles, and conversation can be heard in the audio, but I could not pick out any words that could be confirmed as lines.
Even within 17 seconds, the size of the belly and the naturalness of her smile come across well. One comment writes, "the main video, too, lets you really feel the size of the belly." What is not in the sample is the flow where the female friend and the male friend join, and the content that fills the running time of the main video.
What the Comment Section Says
Of the 63 comments (as of September 27), I could read 20, written from mid-May to the beginning of June. Because one comment can contain several topics, the counts add up to more than 20.
- The most common, at 12 comments, are voices touching on the fact that she is pregnant or on the size of her belly. As in "the pregnancy-themed video was the best!", they line up the satisfaction of people whose taste it matched
- Voices praising the realism and naturalness account for 3 comments. "The pregnant woman feels real" is one of them
- Voices that say the sample was the trigger account for 2 comments: "bought on impulse because of the size of the belly in the sample," and one saying the sample was the first time they were aroused
- Voices writing about being moved or about the sense of being out of the ordinary account for 2 comments. "The sense of being out of the ordinary was the best" is one of them
- One comment waits for the next (the "I'm looking forward to more!" type). There is one question, which doubles as a wish to take part
I found no replies from the poster and no negative comments among the 20 I could read.
What to Know Before You Buy
The running time is 112 minutes (1 hour 52 minutes). The caption does not give a single-purchase price, and カズトラ's page does not list a monthly plan either (as of September 30). Since the release is said to be limited to 100 copies, check on the purchase screen, including whether it can still be bought now. A post with the same title also exists on another account, "Asobinin no Nichijo," and its plan is listed in the Asobinin no Nichijo introduction article.
カズトラ's profile says, "I will delete immediately if I am identified or my boyfriend finds out." Since the caption also gives being identified as the reason for the limited release, if you plan to buy, sooner seems better.
How the face appears matches between the title and the sample. The title says "full face shown," and in the sample, too, the woman's face has no blur; only the man's face is covered by a mosaic.
There are two points that depend on your taste. The first is that this video clearly shows a final-month belly, so it is not for people who do not like pregnancy-themed videos. The other is that the room on screen, as the caption writes, has a strong lived-in feel and cannot be called a polished shooting environment.
Who This Will Hit
- People who want to see the size of a final-month belly together with a smile
- People who like the natural, amateur reactions of someone who "could be anywhere"
- People who want to follow, for close to two hours, the "chaos" that happens in an everyday living space rather than a luxurious room
The 17-second sample shows you the size of the belly and the face laughing shyly. If something pulls you in there, 112 minutes follow. If it is not for you, go to another video. If you are unsure, the 17 seconds come first. If you want to compare with the other videos, start from the カズトラ introduction article.
