The art club's cultural festival is a "Wall Butt Exhibition." What's sticking out from the canvas on the wall are the bare butts of the female club members, a work of art that is so new and erotic! You're allowed to touch them! You can rub them, lick them, and even insert them! On the other side of the wall are the mouths and breasts of the female club members! Of course, you can touch and insert as much as you want! Please enjoy the beautiful butts that we, the art club members, have polished up for this day to your heart's content!
