【解説】アナルセックス直前・直後画像生成方法

1.はじめに

この記事では、アナルセックス直前・直後の画像を生成することを目的とします。

ここで言う直前・直後は、攻め・受け両方が描写されている状態での直前・直後になります。

それらの描写があることで、時系列が生まれ、より動きを感じられるようになります。

ただ、本番画像が比較的簡単に生成できるようになった中で、直前・直後の描写は難しい点もあります。

そのため、解説を進めていきます。

4.解説

体位（例：doggystyle）のタグに加えて、次のタグを加えることで実現しています。

```

imminent penetration, imminent anal

←挿入直前、アナルセックス直前

```

ただし、直前の場合は、射精（例：cum in ass）に関するタグを含めていません。含めるとしてもprecum（先走り汁）までにしています。

事後の場合は、その逆で、射精に関するタグを含めています。

```

cum in ass

←アナル中出し

after anal

←事後アナル

handsfree ejaculation

←ところてん

```

これによって、やや特殊なのですが、二回戦直前で射精する形で直後を表現しています。

ただ、このようなトリックを使わなくても、after anal（事後アナル）だけでも実現できる気もします。

差分画像として、「直前⇒本番」の画像や「本番⇒直後」の画像を生成していますが、これは以前解説したimg2imgによる方法です。

5.おわりに

AI漫画に挑戦されている方が増えており、その成功例も見られるようになってきました。

また、LLM（文章の生成AI）でもNSFWジャンルに対応できるサービスも存在してきています。

本格的に物語るツールとして、AIを利用するタイミングとなったようです。
