Writing erotica - sometimes based on my own experiences, sometimes fiction.
会勾起我性欲的是:
My biggest, get-hard-in-an-instant turn on is any kind of messy sex or solo play. The kind that leaves you dripping from your holes.
When it's more about the mind - the experience, the sensations, less about the visuals, I enjoy electrostim and sight and breath deprivation - talking blindfolds and full latex masks.
