Good girl gets tickles and hitachi

Cassandra calls her diapered step-daughter Red into the room and tells her that she's been such a good girl lately so she wanted to give her a treat. She pulls out the hitachi and starts using it on her, but then she starts playfully tickling her too! She edges, tickles, and teases her and then finally allows her to cum in her diaper and finishes it all with tickles all over.
