It's Just a Threesome. Do You Have Any Objections?

I am Zenyuan Zi. When I was eighteen years old, I allowed my bamboo horse to enjoy a monogamous threesome. No, it's not appropriate to call him a human being. After all— "Urika, your hair is perfect for playing." "Zi, don't bring Li Xiang down..." "Youta... Don't you... Don't like it?" "If you don't like it, you can try my shadow magic~" "That's enough for you two!!!" Intention: I want to do something that only LSP understands
