My shy and beautiful girlfriend turned out to be a cosplayer!? Her name is Eimi, and she's slender, beautiful, and busty - the perfect girlfriend. But she had a secret. She was a cosplayer who secretly cosplayed at home! When I went back to get something I forgot, I saw Eimi in her cosplay outfit, masturbating! Sometimes when I was feeling down, she would cosplay to cheer me up... I thought it was a bit strange, but since cosplay costumes are usually cute... it's totally fine! I want to see more of Eimi's cute cosplay outfits, and it's making me a bit more excited than usual... So let's have sex while Eimi is still in her cosplay outfit! Eimi was super excited by my unexpected reaction! She played the part of a slutty girl, teasing me, but in the end, she couldn't stop herself from riding me hard, making me cum over and over again.
