I found Aya, a girl dressed as a plumber and calling out to customers near Shibuya Center Street. Even though she was wearing a cosplay that was not feminine, her face, twin tails, and slightly lisping way of speaking were so cute that my crotch grew as if it had grown from a mushroom. She said she was working part-time at a cosplay cafe to earn the coins needed to advance to the overseas stage. I invited her by saying that she could get even more coins, and succeeded in taking her to the aerial stage we had prepared. Her casual clothes were girly, and she usually wore glasses, making her three times cuter than when she was in cosplay. My crotch was about to burst into flames. Aya was hesitant to even change into underwear in front of the camera. I told her that if she continued like this, I wouldn't be able to take her to the "back stage" where she could get a lot of coins, so I stimulated her vagina with a toy and gently attacked her cute nipples with a light color to encourage her. Soon Aya's vagina was dripping wet, her clit was throbbing, and she was in an invincible state where I could insert it at any time. The turtle between my legs couldn't hold back any longer and was upgraded from a weakling to the final boss in one go, forcing his way into the pussy castle, thinking, "I wonder if the princess is here~". Every time he thrusts deep inside, instead of the 1UP sound effect, Aya's cute moan of "It feels good~!" echoes. And finally, he reaches the goal. Instead of fireworks, he splashes a huge amount of semen on her tits. It's hard to tell now whether she's a plumber or a princess, but Aya feels good, gets lots of coins, and is very satisfied with having completed the game. If you like, please come and play again~☆
