Harry POV
Harry felt wonderful and sated after the mind-blowing blowjob he had just gotten. Did he actually get a blowjob or was it all in his mind? Harry was not sure what had just happened, but he didn't really care too much. At least, he hadn't until Moaning Myrtle popped up out of the water.
"What the hell?" Harry asked shocked. "Have you been here this whole time? Were you under the water long?"
"Awe, don't be like that. Why don't you ever come to see me anymore?" Myrtle said.
"Myrtle, I asked you a question. How long have you been here?"
"Long enough. I know you have a crush on Mr. Malfoy," Myrtle replied with a laugh.
"Myrtle, you can't tell anyone about that alright? Promise me," Harry told her.
"Awe, alright Potter, just promise to come see me sometime." Myrtle said before leaving.
Harry waited until she was completely out of sight before getting out of the tub. He quickly put his robes back on and used the invisibility cloak to get back to the Gryffindor tower. He pulled out the Marauder's Map when he got to his room, but still didn't see anyone in the bathroom. He did, however, notice that Malfoy had also been wandering around at night. Probably trying to find some way of messing with Gryffindors. Not seeing anything of interest, he put the map away and went to sleep.
The next day at breakfast, he noticed that Malfoy was happier than usual and he seemed to look at Potter every now and then and smirk. Did Myrtle tell him? Harry shook his head, figuring that that couldn't be the reason. Had she told Malfoy about what Harry had done in the bathroom the night before, the Slytherin would have been furious and trying to take Harry's head off, not smiling and laughing with his friends.
Harry, however, couldn't shake the feeling that last night's blowjob wasn't just a really realistic feeling fantasy. He decided that he was going to keep checking the Map to see if anyone returned to the bathroom that late at night during the next week.
1 week later…
Harry hadn't seen anyone on the Map for the whole past week so he decided to go to the bathroom that night to see if maybe there was someone coming to the bathroom that was using some sort of spell that would prevent them from being noticed by the map. He had the map with him to see if people were coming.
The map showed plenty of people in the hall, but they were all teachers or students making their rounds like they had to. He did notice that Malfoy was going off route and it looked like he was heading towards the Prefect bathroom.
Sure enough, Malfoy came to the bathroom. He opened the door and entered. However, as soon as the door closed, and Harry heard a splash of water, Malfoy disappeared off the map.
"What the fuck?" Harry muttered. Harry put the map away and moved out of his hiding place to go see what Malfoy was doing in the bathroom that was confusing the map.
"What the fuck?" Harry said at what he saw.
