Poor Mikey just stared at Jessica as she left the room, turning the light off as she went.

From the humiliation of being seen by his aunt and cousins in nappies and baby knickers, to the ecstasy of her making him cum, to the agony of knowing how cross his aunt would be in the morning – whatever he had been expecting from his first day staying with his aunt, it certainly wasn’t this.

His nappies were so bulky between his legs that he couldn’t even lie as he normally did in bed – his legs were splayed out just like a baby’s. He could feel the elasticated waistband and leg holes of his plastic panties biting into his tummy and thighs. And now he had the additional worry of what his aunt would do when she found out he’d cum in his nappies.

He toyed with the idea of getting up and taking off his soiled nappy. But what would he do with it? He couldn’t just make it disappear. Anyway they’d notice that he only had two nappies on instead of the three he'd been put into. And although he knew there were more nappies in the cupboard he had no idea how to fold one into shape to replace his soiled one.

Sleep came slowly to him, and when it finally arrived it was deeply troubled. His first spanking had been not only intensely humiliating, but also really painful. Now he was facing the prospect of another one as soon as his aunt checked his nappies. And who knew what else might befall him?

He felt like he'd only been asleep a few minutes when Jessica came in and turned the light on in his room. “Morning sleepyhead!” she chirped. “Did you manage to keep your nappies dry after all that milk you drank just before bedtime?”

He’d forgotten the milk he'd been made to drink. Suddenly he had an overwhelming urge to pee.

Before he could reply his aunt came into his room, quickly followed by Emily and Sophie. “Right!” said his aunt, “let’s see if the boy can be trusted or not. Jessica, would you remove his nappies please?”

Jessica pulled back his duvet, revealing his babyish onesie, nappies and plastic panties. He blushed beet red with shame at being exposed like this. But he quickly realised that worse, far worse, was to come. Jessica was going to undo his onesie, pull down his plastic panties and then undo his nappies.

And then not only would he be naked from the waist down in front of the four females, but they’d also be able to see that he’d cum in his nappies.

Jessica reached between his legs and undid the poppers on his onesie. The front part popped up, revealing his plastic panties. Next she tapped his bottom to make him lift up while she pulled down his baby knickers.

He knew his moment of shame was nearly upon him. And there was nothing he could do about it. He just had to accept his fate.

Jessica unpinned his nappies and pulled them down, leaving him exposed to the females’ stares.

It took only a moment for his aunt to notice the yellow stain in his nappy, and the matted gloop in his pubic hair. She was furious.

“Oh my goodness!” she exclaimed. “This is exactly why I don’t trust teenage boys and why I wanted him to wear protection. And he protested he didn’t need it, but he so clearly did! Well, he’s going to need to be punished for this. Jessica – will you give him another spanking, please? I think he needs thirty or forty spanks to teach him a proper lesson. And then he needs to spend the rest of the day in a nappy. We can’t risk him making a mess in his pants, or who knows what else…”

With that she left. Mikey wanted to explain that it was Jessica who'd made him cum, but his aunt had gone. And in any case, he didn’t think she’d believe him. He had no choice but to meekly accept his fate.

“Emily, Sophie, would you be darlings and help me spank him, please?” said Jessica. The girls willingly agreed, excited to see the boy have his bottom spanked. “Would you each go either side of his bed and grab his ankles, then lift them high over his head, so that I can get a really good aim at his bottom with his spanking paddle?”

The girls went either side of him and did as Jessica had requested. Jessica went to retrieve the paddle. His bottom was completely exposed as Jessica began his punishment. Again and again she brought the cruel impleme baulked ent down on his defenceless bottom. He tried his best not to cry, but after twenty or so spanks the pain and humiliation was too intense, and he started to blub.

“Oh look!” said Sophie, “He’s crying like a baby. No wonder he needs nappies!”. Emily giggled. Mikey wished he could just disappear.

After forty spanks his beating finally finished and the girls lowered his legs. “Let’s get you bathed and cleaned up,” chattered Jessica, “and then we can get you ready for your daytime nappy.”

With that she went to run him a bath, and he lay on the bed, tears still streaming down his cheeks, his bottom feeling like it was on fire, and his two cousins giggling at his predicament.

Jessica returned and asked him “Does baby need a wee-wee?” He baulked at such a humiliating question, but realised that he did indeed need to go. He meekly nodded. Jessica took his hand, made him stand up and removed his onesie, leaving him completely naked, his very red bottom clearly on show.

She lead him into the bathroom and made him sit on the toilet.

“But, but…” he protested, “I stand up when I wee!”

Jessica laughed. “It’s going to be quite some time before you stand and wee at a toilet, baby!”

Shamefully, he dropped his head and tinkled into the bowl.

When he was done Jessica put him into the bath and scrubbed him all over. When she was done he was pink all over, apart from his bottom which was still fiery red.

She helped him out of the tub and wrapped a towel around him. “So listen to me,” she said, “your aunt has insisted that you have a nappy on all day today. I'm afraid that means that you won’t be allowed to use the toilet again. So you need to decide – you haven’t had a poo today. Do you want to have to poo in your nappy? Or would you rather I made sure that you didn’t need to fill your nappy like that?”

He stared at her. He was eighteen years old. Just twenty four hours ago he was a normal young man, going to stay with his aunt and cousins. Now he found himself deciding whether or not he should dirty his nappy.

He couldn’t bear the thought of having a poo in his nappy, so asked Jessica what the options were.

“Well,” she said, “it’s not very comfortable or pleasant, but it’s better than the alternative. Wait here while I get things prepared.”

With that she left, returning a few moments later with a large frame holding a bag of soapy water. There was a valve just below the bag and a long tube, at the end of which was a large rubber nozzle.

“This is going to hurt a little bit, baby,” Jessica cooed, “but you know it’s for the best. You don’t want to dirty your nappy, do you?”

She guided him over her lap and rubbed some Vaseline over his little rosebud. “Be a brave baby!” she laughed. And with that she forced the rubber nozzle inside him. He gasped as it invaded him, and felt breathless as she pushed it deeper inside him.

Once it was fully in she released the valve and the soapy water flooded inside him.

It took a full fifteen minutes before he was able to accept the full quart. He felt his inside utterly bloated. He’d never felt anything like it. Jessica sat him on the toilet again and he evacuated his bowels with considerable force.

Jessica just smiled at him. “Does that feel better? At least you know now that you're not going to dirty your nappy. But there’s one more thing. As you're going to be in nappies today, and maybe for a little while, it'd be best if you were, um, easier to clean ‘down there’. Do you know what I mean?”

He looked at her blankly.

“I think we need to remove all your unwanted hair ‘down there’,” she said.

He was aghast. He didn’t have any ‘unwanted’ hair. He had been a late developer and had only had hair for a few years. The last thing he wanted was to lose it. But Jessica was insistent.

She laid him on the bad and sprayed some shaving foam on his little boy bits. She then produced a razor and proceeded to get rid of his pubic hair. The feeling of her stroking his most intimate parts, lifting his willy and stretching the skin over his balls, produced the inevitable result.

She proceeded nevertheless, until he was completely hairless.

“Shouldn’t we remove his other hair too?” piped up Sophie.

Poor Mikey’s heart sank once again, and the girls proceeded to shave his armpits and wax his legs and chest.
