MexTai: Playing Around
Rosa sat perfectly still as Mei played with her hair, trying out various styles and seeing what she could do with the thick mop on Rosa's head. The Asian girl was fascinated by Rosa's curls, and, asides from trying to find a style that worked, she generally enjoyed feeling the texture.
The Mexican flinched as Mei accidentally tugged on a small tangle.
"Sorry," Mei said.
"It's fine," Rosa dismissed.
She could feel as Mei gathered her hair in an updo, most likely trying to determine whether or not it would work, before she released the thick hair, letting the curls cascade around Rosa's shoulders.
Rosa didn't mind that Mei was playing with her hair. To be honest, she always found it to be relaxing. As long as Mei didn't have the bright idea to try and straighten Rosa's hair, or try to blow-wave it, everything would be fine.
I was in the mood for yuri, so there you go.
My sister's attempt at blow-waving my hair resulted in me being banned by my mother from using hairdryers.
