Waterslide Mass (Monochrome) (Pixiv Fanbox)

*ALL CHARACTERS ARE OVER 18 YEARS OLD It's their time to move on to another theme park. Just take the waterslide, and join the others! With tons of water, you won't be digested so quickly there. :p Btw I HATE to draw backgrounds but I had no choice for this one lol. I wish you enjoy!
