水中ディープキスで出る泡開発/Development of bubbles from underwater deep kissing. (Pixiv Fanbox)

息がそろそろ限界になりつつ、喉で息を止めたままべろちゅーで暴れた水の動きによって出る泡ってエロいよね。という情熱で2時間ちかく掛けて泡の開発をしておりました。

Bubbles caused by the movements of the water that went wild in the tongue while holding their breath in their throat are erotic, aren't they? I spent about two hours developing the bubbles with such passion.
