Inscribe a sigil on your metamour's back in vinegar.
Drink a cup of tea and have a metamour tie the used tea bag to their body for a day.
Make bars of soap for your metamours to use.
Paint your metamours' nails while they are blindfolded.
Feel free to add your own...
re: Intimacy that stays with you all day
@emanate I mean, body paint is fine but vinegar kinda gets absorbed and shines in light?
I dunno, was just thinking about using food or another intimate liquids on folks.
