Still not sure, but she's apparently done this before

Phil could barely concentrate all day at school. Every time he tried to pay attention, his cock would twitch and tingle, almost as if Blooma was testing him on purpose. He was slightly annoyed but still enjoyed her attention, finding it hard not to smile a little as she did what she wanted to his penis. He could swear he heard her giggle a few times, like she was doing it on purpose.

He didn't go to his art class today as he had a test to do in another, but he had heard rumors that something weird had happened in there, though none of the students seemed to want to talk about it. He saw a bunch of them walking away from the class with their clothes half on and hair disheveled, almost like they were all taking the walk of shame.

He was curious as to what had happened but his penis had different intentions as Blooma kept teasing him mercilessly. There was constantly a tiny wet spot of precum on his pants all day, and it got to the point where he ended up skipping his last class and heading home just because he couldn't take it anymore.

He was a few feet from his apartment door when Blooma finally spoke to him. "Skipping class to spend time with me?" She said with a giggle.

"You've been teasing me all day."

"Ah, you like it, though, don't you?" She said as his foreskin tightened around the tip of his cock, moving slightly like it was sucking on itself. "I've just been making a few adjustments in here to make things more fun."

"I really don't like you changing my penis."

"Oh, you need to relax," she said with a chuckle as he entered the apartment, shutting the door behind him. "Oh, good, now we can have some real fun."

"Wait, I have to......" he said as he opened the bathroom door and froze when he saw the giant wall of flowery moss all over the wall. "Wha........ what the fuck?" He asked, seeing the flowers pulsing and what looked like pollen filling the air.

"Like what I've done to the place?"

"What the fuck Blooma? What the Hell are you doing to me?" He asked, feeling his cock twitch again before finally taking his pants off. "Oh my God!"

Phil's penis had completely turned a dark green color. The tip was purple and the precum stain on his underwear was more of a lime green color as his cock twitched and pulsed.

"WHAT THE FUCK HAVE YOU DONE TO ME?"

"Oh, Phil," she said before she laughed hysterically. "You men are all the same."

"What are you talking about?"

"This isn't my first penis, in fact I do this all the time."

"What do you mean? What are you doing to me? Why?"

"You'll see soon enough. But why? I'm a pixie, it's what we do. Penis's are so special, giving us life creating fluids. I just make a few adjustments, and boom, we can start growing new forests."

"But....... I didn't do anything to you. I tried to help you."

"Yes, you did. Don't worry, I meant what I said when I told you you'd experience endless pleasure. I'm actually very good at this now. It was fun making you think this was an accident, but bonding with penis's is my specialty.

"So........ you're not......"

"Leaving? Nope, you are stuck with me now!"
