Diapered and at her mercy, the submissive lies on his back, legs spread, as Mistress Stephenson takes her seat. She runs a gloved hand over his diaper, feeling the warmth, the dampness. She smiles, knowing he's turned on, humiliated, and loving it. She picks up a riding crop, tracing the tip along his inner thigh, making him quiver. A sharp smack against his diaper-covered crotch draws a gasp. She continues, alternating between harsh strikes and gentle caresses, her touch a cruel dance of pleasure and pain. She watches, entranced, as his cock hardens, tenting the diaper. She leans in, whispering, "You love this, don't you? The humiliation, the pain, the helplessness." He nods, his voice barely a whisper, "Yes, Mistress."
