Nikki has been improving her behavior due to Step-Daddy's diligent maintenance spankings. As a reward, Step-Daddy surprises Nikki with the jumper. He helps her into the jumper and zips it shut around the bulky cloth diaper she is wearing. She hangs in the jumper and swings around, her feet not touching the floor.

The tension in the jumper causes her diaper to ride up, putting a comfortable pressure against her pussy through the padding. She smiles and secretly uses it for pleasure- meanwhile putting on a happy face for Step-Daddy.
