Rosie testes the first time, how it's to sit and bounce on her slave's face.
He lies on a bouncing-mat, she begins foreward, sits down, shakes her hips and shoves his nose to the right place in her crotch.
The she turns around, reverse maybe is better for a ride, his nose goes up to her ass-crack.
A little try with sideward, then again reverse is the best!
