Scene D4: 終わらない快楽 (追加差分) / Endless Pleasures (Additional Diff)

定点ソファ絵の追加差分「オナホとして使われる柑奈」を投稿します。３枚目が新作になります。４連作そろったので他の３枚も再掲させてください。

I am posting an additional difference of the fixed-point sofa picture “Kanna being used as a masturbator”. The third one is a new one, and I'd like to repost the other three pictures now that I've completed the four series.
