Severus swallowed the boy's semen, impressed and aroused by the taste in his mouth. He adjusted his own trousers, trying to relive his tightened clothing due to his own erection. It would need tending too, soon.
He cleaned Harry up quickly and gently. He brought the diaper's front over Harry and taped it into place. He smiled at the little one and noticed he was asleep, exhausted from the day and his first orgasm.
Severus brought Harry to his crib, setting him down to sleep. He put his soft blanket over him, and clipped the pacifier to his shirt so he wouldn't lose it while he slept.
Severus set up the baby monitor, making sure Harry was within the frame and it would alert him if he was needed. He placed a swift kiss on his forehead, "Goodnight baby".
He returned to his own bedroom, stripped quickly, and entered his private bathroom/shower. He started the water, letting it heat up to a blistering temperature and stepped in. He let the entire day play before his mind's eye. The classroom defiance, the triumph of the headmaster approving the "punishment", and every moment up until this one of Harry's regression.
He was surprised how quickly things have turned between himself and Harry. He did not anticipate for the boy to clench his role like he has. He assumed the child size toilet would be around for at least 2 days before transitioning the boy to diapers, but he was pleasantly surprised to squash that tonight. He certainly did not expect the sexual portion to happen this early on either, but he wasn't complaining. He vowed to take care of Harry's needs, and that included sexual ones.
He moved his hand to his own length as he remembered the warm feeling of Harry's accident spreading across his chest, and the innocent fear that the boy's eyes hand when he realized his accident. He stroked leisurely.
The warmth that spread on his chest, those eyes. The eyes of shock with his accident, his eyes when Severus stripped from his clothes, his eyes on this erection that he has in his hand. Severus moaned. The trust that Harry placed in him to lead him to his first orgasm, it filled Severus more than anything else. He stroked with vigor, and the push over the edge was remembering Harry's shout with a paci in his mouth, 'Daddy!' Severus came, moaning to himself "Oh baby."
As he watched his seed go down the drain, a blood curdling scream met his ears. He quickly shut off the shower, grabbed a towel, and sprinted to his baby. He flung the door open quickly but gently, he kept the lights off to keep the boy from waking fully.
Harry was standing in the crib against the railings, paci out of his mouth, his wails at an all-time high. He hadn't even been asleep 20 minutes. Severus picked him up and held him tightly to his damp chest. He began a slight bounce-walk across the nursery. "Sh, sh, sh baby. What's a matter bug?"
The wailing continued, hysterical sobs wrenching from the boys chest. Looking in Harry's eyes he could see he was likely still sleeping from the dazed look in them. His baby was having a night terror. He used legilemency to see his baby's dream state.
Severus was met with an intense darkness. There were shadows, with red eyes, hissing, and coldness. He could not make out the scene, and could only feel the intense fear of it all. He felt trapped, alone, and abandoned. The fear was in every fiber of Harry's being.
Severus used his access to start to impress himself into the scary dream. He showed himself in a bright, patronus like light. He approached Harry, who appeared in his mind space of being 2 yrs old. He spoke soothing, loving words, to help the boy calm and detatch from the nightmare in front of him.
Harry woke with a start and wailed "Daddy".
"Right here baby, right here, sh, sh, sh," Severus sighed, glad it worked to pull him from the night terror, and provided him soothing. He pushed the paci past Harry's lips, and he sucked readily.
"Want to sleep with me baby?"
Harry nodded, around his paci "Sleep wif daddy"
Severus took Harry's blanket with them, and brought him back to his room. Harry couldn't see the appearance of the room, and just focused on staying close to daddy's chest. He felt safe, warm, protected. Severus laid down, and pulled Harry on top of his chest so he could feel the rhythmic breathing between them.
"Let's sleep baby boy," Severus brushed the baby's hair softly. He felt him relax, and fade off into sleep. Severus followed suit quickly. The first night was down in the books.
Harry woke with a start. He rubbed his eyes and groaned as his dreams. He had visions of a detention with Snape that made him a baby. It was terrifying. He shifted in his bed and opened his eyes. This was not his room. His normally red canopy over his bed was now green and silver. The wood head and foot board was now a solid, polished black that shone. His blanket was childish, soft minky material with bumps that are seen on baby blankets.
His heart stopped for a breath. It couldn't be true. He turned to look next to him. None other than Professor Snape was sleeping soundly next to him.
The detention, the spankings, the potty, diaper, and the… the experience he had, they were all true. He felt the sting on his bottom to remind him of his misgivings against the professor. His face blushed deeply as his groin stirred, remembering his first orgasm the night before.
He clenched his bottom as his stomach began to rumble dangerously. He always used the bathroom in the evening, but with yesterday being the insanity it was, he hadn't. He looked down, seeing the diaper on his nether regions.
No. Fucking. Way. Harry thought to himself. He eyed the professor again, and slowly made his way out from under the blankets and off the bed. Counting his blessings, he thanked Godric that the bedroom door was ajar. He padded softly out of the room trying to remember where the bathroom was. He didn't dare use Snape's, he would hear him!
He opened 2 doors before he found the right one. It opened without a problem. Harry let out a huge sigh. Luck was on his side this morning. He pulled one of the tabs on his diaper, and before it was completely untaped an alarm sounded.
Harry covered his ears and fell backwards. Oh Godric. Snape would wake up. He would know, he would find him, he would be spanked again. Harry quickly climbed into the bath and closed the shower curtain to hide.
It took 2 breaths for Snape to show up in the door way. Harry curled tightly against the side of the tub, trying to melt into the porcelain.
Snape approached without pause, and immediately pulled back the curtain to find Harry. Harry flinched unconsciously, but tried to make a scowl appear across his face. He was an ADULT! He was NOT a small child, a BABY in the presence of this man!
"What are you doing Harry?" Snape asked.
Harry quirked his head sideways at the gentle name and tone Snape used towards him.
"I have to go bathroom!" Harry exclaimed. "Right NOW SNAPE!"
Snape's eyes instantly went dark at the way Harry yelled and used his last name like a curse word.
"That's what your diaper is for baby. I won't punish you for getting up without waking me, or trying to take off your diaper. I didn't get a chance to tell you it was against the rules. But if you do it again, there will be spankings. Mind your tone with your daddy Harry."
Harry's blood pressure rose, "You is not my daddy Snape!" He raised his hand, bringing it back to hit Snape, before he was swiftly picked up and a hard smack landed on his inner thigh.
"NO Baby. You do NOT talk that way to daddy," Snape said, holding his wrist to prevent the strike from Harry.
"NOT A BABY! YOU NOT DADDY! YOU NOT! FUCK YOU!" Harry raged.
Snape sighed, prepared for this push back. It would take time. He brought Harry to the couch, untaped the diaper to let it drop, and spanked Harry with 15 swats to his already red bottom from yesterday.
"I understand you are tired, confused, and have to go potty baby, but you will NOT talk to daddy like that, ever!" Snape walked Harry over to a bench in a corner that said "Time out".
"Stay there until I tell you to come out baby, and not making messes," he warned.
Harry raged in the corner. He screamed, cursed, kicked, pound his fist against the nearest wall. The rage took over for what felt like forever. It drained every ounce of energy he had gained from his previous night sleep. Finally his body hunched over with exhaustion in the corner, the tears and rage dried up, and he sat quietly, naked, and shamed.
Snape approached, "Are you ready to come out baby?"
Harry nodded and reached his hands up. "Hold?"
Snape cuddled him to him and brought him back to the couch where the discarded diaper lie. He laid Harry back and put the diaper under his bum.
"I want use potty. Big boy," Harry said between sniffles.
"Sorry baby," Severus said. "You're too little for the potty. We use diapers."
Harry's face went red again with anger and embarrassment. He would not, he COULD NOT, use the diaper. He couldn't, he couldn't, he couldn't. He clenched his bottom, reserving himself to hold his poop until Snape could see how ridiculous he was being.
Sensing Harry's oncoming tantrum Severus picked him up and bounced him. "It's ok to use diapers Harry, you're just a baby. Daddy wants to take care of your wet and messy diapers."
Harry shook his head. Refusing. Severus carried him to the dining area, equipped with high chair large enough for Harry, and set him in, using the clips and straps to ensure he was safe, or maybe so he could not escape. He attached the high chair table top, and set some baby cereal for Harry to eat.
Harry ate slowly, disliking the baby treatment, but so hungry for food he didn't argue. He liked the cereal. He preferred it with a bowl of milk and a spoon, but he wasn't about to complain. Banana and another fruit he didn't recognize were added to his tray and he quickly used his hands to eat it.
Severus went making his own breakfast of eggs, bacon, toast, and coffee. He got a bottle for Harry, and filled it with warm milk, slight vanilla flavor, and added some laxative without the boy noticing. He was happy Harry was eating the prunes without a fight.
He set the bottle in front of Harry, who wrinkled his nose and promptly ignored it as he ate.
