Endless Vacation (Patreon)

It already September, the summer vacation should be end at last week, but Artoria found herself have been summoned to a beachside resort singularity. 

By the time past, she find out when she spent more time enjoy the facility in the water, the more pleasure she gain. 

Finally, she becomes one of facility in this singularity, though her mind still believes she was lying on the surface overlook the whole resort.
