The old bitch, her eyes gleaming with power, commands her adult baby to lie back on the changing table. She secures his wrists and ankles, leaving him helpless and vulnerable. She runs her fingers over his diaper, feeling the dampness within, a sign of his excitement. She removes the pacifier from his mouth, replacing it with the head of her strap-on. She fucks his mouth, slow and steady, her hips rolling in a rhythm that matches his sucking. She pulls back, allowing him a moment to catch his breath before she resumes, her pace quickening, her moans filling the room.
