Chapter Text
He had been going to Hogwarts for two months now before he looked up the spell. Harry still couldn’t believe he was so dense - all the wasted time! Two months of only wanking and pissing in the shower to have at least some relief. But now, equipped with a spell that would vanish his urine instantly, there was a whole new world of possibilities!
As soon as he found it, he went to the loo and tried it. He pissed in the bowl and muttered the spell. A second later, every piece of evidence was gone. Idea after idea was flooding his mind. All the things he dreamed about and everything he ever wanted to try out, but couldn’t because he was still living with the Dursleys could now become true. There was absolutely no more reason to hold back.
At first, he wanted to try out something he had fantasised about since he was 15. In the evening, he drank as much as possible. Once his bladder was full enough to make him uncomfortable, he said good night to his friends and headed to bed, not caring that it was half an hour earlier than usual. His thoughts had revolved around nothing but the spell, and he was only half listening anyway.
Once in the dorm, he didn’t bother to use the bathroom, changed into his pyjamas and headed straight to his bed. Once he closed the curtains around his bed, he was shaking with excitement.
He lay down and took a deep breath. It was happening. After so many years of wanking to this fantasy, it was about to come true. Even better, it would come true, and he didn’t have to take care of the mess. Magic is fucking amazing!
He waited a little more, wanting to make sure his bladder was as full as possible. When he was rewarded with a small cramp in his lower abdomen, he knew it was time. Once he was lying as comfortable as possible, and he made sure his dick was flat against his stomach, he relaxed.
A moment later he could feel the pleasant tickle in his bladder and soon after in his dick, as the piss was making his way out. A sigh escaped him, as the hissing started and a nice thick stream of piss was flowing out of him. Warm wetness was spreading on his stomach before it flowed down his sides and collected beneath him. In only a few moments, the mattress underneath him was wet to his butt, and there was a lot more to come.
The feeling of his own piss combined with the feeling of his bladder slowly deflating made him hard. He was still pissing strong when he wrapped his hand around his hard cock and started stoking.
When the stream was starting to cease, he felt a familiar build-up in his belly and together with the last drops of piss, cum came shooting out of his cock. He threw his head back and tried his hardest not to moan loudly.
He lay there for a few more minutes, savouring the feeling of warm piss all around him, before he finally took his wand and vanished it. A second later everything was dry once more, and he missed the feeling immediately.
And that was only the beginning, he thought and closed his eyes, falling into a piss-filled dream.
