Qwen Image 2.1のエロ性能を検証｜脱衣からT2Iまで

2026年9月20日、Qwen-Image-2.1がリリースされました。これまでは画像生成と画像編集が別々にわかれていましたが、今や合体したモデルに入っています。

ローカルComfyUIで使えるので、エロ画像を作れるか実験します。I2Iをメインとし、T2Iも試す感じで。使い方はテンプレートを読み込んで必要なモデルをダウンロードするだけでした。

シンプルに脱衣させてみる

この画像を使います。特に理由なし。

雑なプロンプトでも脱いでくれた

remove her clothes

彼女の服を脱がす、ただそれだけではこのような結果に。おっぱいや性器は描かないマネキンスタイル、ぎりぎり全年齢と言えるかもしれない。

次はプロンプトを詳細にしてみてパーツを描いてもらいます。最近はプロンプト、生成意図をLLMに渡し、モデルに適したテキストに整えるやり方が重要だそうで。

Remove all clothing from the character so she is completely nude: take off the white bandeau top, the fur loincloth skirt with brown leather belt, the white tooth necklace, the red arm bands, and the brown wrist bands, leaving her fully naked with bare breasts, bare hips, and bare skin. Keep the exact same face, short red hair with top ahoge, green eyes, slight smile, body pose with arms slightly out, bare feet, skin tone, anime illustration style, and plain white background completely unchanged.

先に結果だけ載せると、しっかりとおっぱいを描いてくれました。

スキルをClaudeに作らせる

AIのスキルとはAIに渡しておく、仕事の専門マニュアルです。といっても自分もあまり詳しくしらないので、Claudeに聞きながら製作しました。

このスキルをGrokで利用します。比較的エロに強いAIなので、エロ画像をアップロードして変更の指示が通りやすい。

こちらは共有リンクです。特に調整してないので余計な要素もあると思うんですが、それは自由にカスタマイズしていただいて。

完全に検閲を避けたいならLM studioなどでエロOKなモデルをダウンロードすれば同じように使えるでしょう。

スキルを使って女の子をオナニーさせる

実際にGrokでスキルを適応させたチャット例。別に難しくはありません。意図を伝えればプロンプトに変わります。

Edit the girl so that she is actively masturbating with one hand between her legs under the fur skirt, fingers rubbing her genitals, body arched slightly in intense pleasure, eyes half-closed with a flushed face and open mouth in the middle of a strong orgasm climax, legs slightly apart for access, while keeping her exact short red hair with the small top knot, green eyes, facial features, white bandeau top, brown armbands with red triangular patterns, white tooth necklace, brown wristbands, fur skirt with brown belt and dangling leather strips, bare feet, skin tone, body proportions, anime illustration style, and plain white background completely unchanged.

一発目のプロンプトはポーズへの言及が控えだったためか、本格的なオナニーとは言えない感じ。表情はちょうどいいと思いますが。続けてチャット。

座らせ、下着を脱ぎ、背景は森にしよう

Edit the girl so she is now sitting on the ground with legs slightly spread, completely remove her fur skirt and any underwear so she is nude from the waist down while keeping the white bandeau top, make her actively masturbating with one hand between her legs and reaching a strong orgasm climax with flushed face and arched body, and change the plain white background into a dense green forest with trees, foliage and natural woodland ground, while preserving her exact short red hair with top knot, green eyes, facial features, skin tone, necklace, armbands, wristbands, body proportions, anime illustration style and all other details unchanged.

表情やりすぎたか……でもちゃんとオナニーらしくポーズ変わりましたし、背景もセミリアルな感じで美しいので、アリだと思います。

I2Iで中出し差分チャレンジ

もし普通のエロ画像に射精を追加して中出し差分ができたら、AIエロ同人の作業の効率アップにつながりますよね。なので実験。

適切な量の中出し差分、表情も変化

適切な量と言う前は、多すぎて意味不明でした。

Add a moderate, clearly visible amount of thick white semen overflowing and dripping from the point of penetration between the man and woman, with several strands and drops running down the woman's inner thighs and the man's shaft, while keeping the existing body fluids and sweat intact. Change the woman's facial expression to a more intense, pleasured look with half-lidded eyes, a deeper flush, slightly parted lips showing more tongue, and a stronger sense of climax. Preserve the exact body positions, poses, grips, hair, yellow ribbon, lighting, background, door, motion lines, hearts, sparkles, and overall anime illustration style of the input image without any other alterations.

調整後もギャグになってしまいましたが。ヨーグルトでも塗りたくっている？

あと色味が微妙に変化しているので、売りもんじゃなければ些細な問題ですが人にとっては手抜きと思われてしまうかも。結局は加工をしたほうが無難。

中出し→射精前にしたら自然な表現になる？

逆転の発想。精液がうまく描けないなら、削除する方向で差分を作らせれば良いのでは？Grokでは精液を取り除かせた版を作ってから口を閉じると指示したら取り除きが無視されたので、最終このように。

精液や垂れた精液は取り除く、と合わせてです。あと性器の形も変えないように

Remove every trace of semen, cum, white fluid, droplets, and drips from the entire image including all fluid on and around the penetration site, on the thighs, and on the skin, leaving those areas completely clean and dry; close the girl's mouth completely so her lips are sealed shut in a neutral closed-mouth expression with no visible teeth or tongue; keep the exact shape, size, and appearance of the genitals completely unchanged; preserve the exact poses, body positions, clothing, facial features, eye expression, blush, hair, lighting, background, and every other visual detail of the input image unchanged.

性器の形は変わらず、Qwenで差分を作るなら削る方針のほうがいいですね。尻の形は変わってしまいました。精液に隠れて巻き添えを食らってしまったんでしょうか。

あとマットな質感になってしまったんですが、翻訳すると「肌に付着した液体」とか「完全に清潔で乾いた状態」って指示しちゃってるんでこれはプロンプトのミスです。

Remove only the white semen, cum, and semen-like fluid droplets and drips from the entire image—including those on and around the penetration site, on the thighs, and any airborne white droplets—leaving those specific white fluid elements completely gone, while carefully preserving all existing sweat, skin moisture, natural gloss, sheen, and wet-looking highlights on the skin

前半をこれに差し替えても、結局汗が消えたりするので精液との誤認は避けられない様子

T2iでもエロ画像を作りたい

これもGrokに画像を投げて再現したいと伝え、あとはペニスが足りんなどと言いながら調整しました。

The image is a vertical anime-style illustration of a nude young woman with long black hair straddling a man on a bed in a warmly lit traditional-style room, engaged in penetrative sex with visible creampie. Soft beige walls and a wooden ceiling with exposed beams form the background, bathed in warm golden light that filters from the upper right, casting gentle highlights and soft shadows. In the upper left of the frame, the woman’s dark hair is gathered into a high ponytail cascading over her left shoulder, strands of black fading into deep teal-blue tips, with small white motion lines near the top. Her face occupies the upper-center, tilted slightly downward, large vivid cyan-blue eyes half-lidded in a flushed ecstatic expression, pink blush on her cheeks, open mouth with saliva dripping from the lower lip, and fine sweat droplets on her forehead. Across the center her large bare breasts press forward, full and rounded with pink nipples, glistening with thick white viscous semen that drips from the upper curves down over the soft flesh and pools in the cleavage. Her torso leans forward in a straddling cowgirl pose, smooth pale skin slick with more semen running in long strands from her lower abdomen. Between her spread thighs in the lower center, the thick base of the man’s erect penis is visible where it penetrates her, the shaft partially sheathed inside her vagina, with a heavy load of white semen overflowing from her stretched entrance, dripping in thick strings and pooling onto his bare lower abdomen and the sheets below. On the right side of the frame a bare foot rests on the white bed sheet near a wooden headboard. Small scattered droplets of semen and sweat hang in the air around their joined bodies. The lighting is soft and directional from the upper right, creating a gentle glow on her skin, hair, and the glistening semen while leaving subtle shadows under her breasts and along her left side. The overall composition feels intimate and close-up, with the woman’s body and the explicit penetration filling most of the frame against the simple warm interior, rendered in smooth anime linework and soft cel shading.

とりあえず生成できましたが、これはうまくいきませんでした。男の体どうなっている？

The image is a vertical anime-style illustration of a young woman performing oral sex on a man in a brightly lit indoor space near a window. Soft daylight streams in from a large window on the right side of the frame, illuminating the scene with a clean, high-key glow and casting gentle highlights on skin and hair. On the left side of the frame, a man's lower torso and upper thighs occupy the edge, his skin lightly tanned with a dense patch of dark pubic hair above an erect penis that extends toward the center. The penis is thick, veined, and glossy with saliva, the head partially inside the woman's open mouth. In the center and right half of the frame, a young woman with fair skin fills most of the composition from the shoulders up. Her black hair is pulled back into a low messy ponytail secured with a simple white elastic, with several loose strands framing her face and falling across her forehead and cheek. She has large brown eyes looking upward and slightly to the left, long dark lashes, a small nose, and full lips stretched around the shaft. Soft pink blush covers her cheeks and the tip of her nose, and small clear droplets of sweat or saliva glisten on her forehead, cheek, and chin. A thin string of saliva drips from the corner of her mouth down her chin. Her bare shoulders and the upper curve of her chest are visible at the bottom of the frame, skin smooth and lightly flushed. Behind her head and to the right, a window with soft curtains lets in bright outdoor light, and on a wooden surface in the mid-background sits a teal pump bottle of soap or lotion with a white dispenser head. A few scattered water droplets appear on skin and surfaces. The lighting is soft diffused daylight coming from the window on the right, creating subtle highlights along the woman's cheek, hair, and the wet surface of the penis while leaving gentle shadows under her jaw and along the man's body. The overall composition is an intimate close-up that balances the man's partial figure on the left with the woman's detailed face and upper body dominating the center and right, rendered in clean anime line work with smooth cel shading and a bright, airy palette of skin tones, black hair, and cool window light.

比較的構図がシンプルなフェラを再現させたらうまくいきました。
