It's bedtime & Billy knows he needs to have his diapers on for his bedwetting issues but when step-mom comes in to check, she pulls back the covers to see he's only in his pullups! he thinks he's a big boy but got busted by stepmom (diaperperv) and she comes back with a tabbed diaper which she changes him into. She's scolding him lightly & tells him to go to bed! She peeks in later & catches him with his hands down his diaper, playing! She is MAD & takes him into the nursery room where she gives him a spanking over his diaper & also on his bare thighs. She feels bad afterwards and brings out the vibrating wand, helping him cum in his diapers as an apology (and she knows he'll just keep being naughty since his peepee is still hard and this is the only way it'll go down.) She needs to put her hands down his diapers to make him cum & once he does, she gives him diaper pats while cuddling in the crib.  He's got to rest in his sticky lil tight diapers now.
