I've always played with water before, so when I poured a bottle of cooking oil over my trunks and t-shirt, the feeling was amazing! It runs slowly, clings and wets in a completely different way! Enjoyed it! Now I'm wondering whether oil is messy or wet?

These are incredible! I love oil play!

Oil can be both messy and wet I think.
I have played with oil on multiple occasions and the way it makes your clothes cling and feel is amazing.
