Underwater Experiment [Commission] (Pixiv Fanbox)

Since the dawn of time, people have been asking the most important question: can people be tickled underwater? Luckily, a kinky science facility has finally decided to answer this question once and for all. Their volunteer is as passionate about answering this question as they are, so they wasted no time getting this experiment underway!
