The room smelled like powder and rubber. Marcus stood naked in the center, his cock already half-hard from the shame alone. Mistress Lena circled him, the thick diaper crinkling in her hands.
"Hands behind your back, sissy. This is what you begged for."
She taped the diaper on tight, the plastic front bulging around his balls. The moment it was secure she pushed him to his knees and unzipped her pants. A thick, veined cock sprang out, already leaking.
"Open."
Marcus opened. The first thrust gagged him, but she held his head and kept pushing until his nose pressed into her pelvis. Spit ran down his chin and soaked the top of the diaper. She fucked his throat in short, brutal strokes while she told him exactly what he was.
"You're not a man anymore. You're a diapered sissy who gets used by real cock. Say it."
He tried to speak around the shaft. The words came out wet and broken.
She pulled out, slapped his face with her wet dick, then hauled him up and bent him over the changing table. The diaper was pulled aside just enough for her to line up and shove in. Marcus cried out at the stretch, but the sound turned into a moan when she started pounding.
Every thrust made the diaper crinkle loudly. His own cock rubbed against the padded front, leaking steadily. She reached around and squeezed the bulge.
"Look at you, getting hard in your diaper while I fuck your sissy hole. You're going to come like this, aren't you?"
He nodded, whimpering. She fucked him harder, deeper, until his legs shook. When he came, it was sudden and helpless, pulsing into the already wet padding. She kept going until she filled him, then taped the diaper back into place so nothing could leak out.
"Keep it in overnight, sissy. Tomorrow we bring friends."
