Forgotten manhua

I'm no actually sure wether it's a manga, manhua or manhwa. It's been a really long time since I read it. One particular scene that I still remember is when they papapa and the gong as the shou to ride on a horse or pony(it's a s@xtoy) and they are in a s@x hotel at that time. I think the pony has like to horn which is on top of its head and on its body, after that the shou accidentally broke the horn, and the gong said that the pony cost so expensive (it's a lie). I read this about 6/7 years ago, and I really hope to find it again. I used to read it on an apps and note here. Thanks it advance is someone found it. ε=ε=(ノ≧∇≦)ノ
