It had taken a few weeks, but Marceline finally managed to convince Princess Bubblegum to go boy peeping with her. Their odd friendship had grown, and their mutual friendship with Finn helped move things along. He had just turned 14 and was one step closer to being a man, which was one step enough for girls to be drooling over his naked body. Or at least that's how Marceline put it. Princess Bubblegum pretended to be reluctant to go and said she was only interested "as a scientist," even though it was quite clear that she had other motivations. When she had found some spare time, she and Marceline went over to spy on Finn.
"What kind of a weirdo has an entire room for a shower…and one with a window?" Marceline giggled. "Lucky for us though, right?"
"Didn't you used to live here...?"
"Yeah. But I'm not the one who put in that fancy pancy shower. I guess those boys like to live in style, even if they're living in a tree…"
Marceline pulled out a pair of binoculars that Princess Bubblegum had brought, and she waited for Finn to take his daily shower. They had found a nice little hill to sit on that was far enough away to avoid being seen but close enough to get a good look. The princess was lying flat on her stomach while Marceline sat under her shady umbrella. It didn't take long for the little adventurer to burst in the door. The girls gasped softly to themselves and waited for the show. Marceline held the binoculars snuggly, and Princess Bubblegum strained her eyes and tried to see as best she could without them.
"Wow! His hair is even more impressive than I remembered," Marceline exclaimed as Finn gracefully removed his hat. "It's shorter than I remember though, but it still looks great."
"Let me see," begged the princess until Marceline handed her the binoculars. "Wow…I don't think I've ever had such a clear view of his hair. It's…magnificent!"
"Haha. Don't start cumming now, PB. We still haven't seen the main attraction. And I'll be the one with the binoculars for the grand entrance, since you're only here for science anyway."
"Oh…um…of course," the princess sighed and gave the binoculars back to her friend.
"Here it comes, baby!"
Finn jumped out of his clothing as if by magic, and he kicked them across the floor away from the shower head. He was completely naked. Marceline tried to keep her cool, but sexual restraint wasn't one of her strong points. She drooled uncontrollably and let out a shivery sigh as she leaned forward. The wetness between her legs could almost be seen through her tight jeans.
"Let me tell ya, PB. I've seen hundreds of hotties in my day. Finn may not be the buffest or the biggest guy I've ever seen, but there's just something so…special about seeing him like this."
"It sounds like the big bad vampire is in love," Princess Bubblegum teased.
"Hmph. Whatever. All I know is that I want a piece of that."
"Does he um…have blond pubic hair?" the princess asked timidly.
"Ah! The first scientific inquiry! I was waiting for you to get interested."
"Well…?"
"Let me check. Nope. We've got ourselves a baldy. He either shaves down there or just hasn't grown any yet."
"According to my research," said the princess, "he probably grew pubic hair when he was about 12 years old."
"So he's had two years to grow wonderful golden pubes, and he just shaved them off? Well that's a letdown."
"So…how does the rest look, Marceline?"
"Why don't you look for yourself? Here take these."
"No. I'm alright..."
"If you say so, PB," Marceline said with a wink. "Well he's a little more plump than I usually like, but it's a cute kind of plump. And his shoulders look broader somehow when he's naked, which is pretty sweet." She paused for a few seconds to take it all in.
"Go on…" the princess said while trying to hide her impatience.
"He's got a tight little ass. It's just begging for a spanking," Marceline said with an evil grin. "What really impresses me is his confidence. I know he thinks he's alone…but damn! He's struttin' around that shower like a pro."
Princess Bubblegum squinted her eyes and placed her hand on her forehead to block the sunlight; she could just barely see Finn washing himself through the large window.
Suddenly Marceline started to laugh to herself.
"What's so funny?" asked Bubblegum.
"For a second I thought he had a third nipple, but it just turned out to be a zit."
"How does his penis look?" the princess finally ventured to ask. "Does it look…um…healthy?"
"I don't want to sound cruel, but there's not much to see. It sure is a tiny little thing but not in a bad way. I guess… There's a certain charm to it. It's like a cute little worm or something." The vampire stuck out her finger and wiggled it around while making a weird "doolooolololoooloolooo" sound with her tongue. She even managed to get the princess to laugh, who had been getting more and more anxious.
"So he isn't erect?"
"I'd feel bad for him if he was," Marceline laughed. "Because like I said, that thing is on the tiny side. Why don't you burst in there, PB? That should get that little willy going."
"I don't think that will be necessary," Bubblegum answered calmly, trying not to get upset over Marceline's playful suggestion.
"Why not?"
"I read that physical or visual stimulation isn't required for a boy to get an erection. Erections are natural things that can occur in any situation. It all has to do with the blood flow—"
"Okay. Okay," Marceline chuckled. "I get it. So what about cum? Will he need any stimulation to give us a chance to see the white stuff?"
"I thought you were experienced, Marceline. Surely you know about semen and ejaculations."
"Of course I do," Marceline said with a hint of annoyance. "You just seem to know a few details I wasn't sure about, like boys being able to magically get hard for no reason."
"Well to answer your question, no. Although I've read that it is possible, I doubt Finn can ejaculate without direct stimulation."
"So in other words…unless he starts jerking it, we're out of luck."
"Precisely."
"Oh well. Let's hope for the best," said Marceline.
"Did you get a good look at his—"
"Hold on, girl," laughed Marceline. "Don't rush me."
Princess Bubblegum shut her mouth and waited patiently, and she noticed that one of Marceline's hands had snuck down into her jeans.
"C'mon! Jump around, Finny! Let's see those balls bounce!" Marceline said with glee.
"Testicles."
"What…?"
"They're called testicles. If you're going to obsess over something, you should at least know the proper term."
"You're such a nerd, PB."
"And you're a pervert," Bubblegum teased back.
"Well you're just as guilty. You're the one that brought the binoculars."
"I'm only interested in the unique anatomy of humans. They're very rare, you know."
"Unique?" Marceline laughed. "If you haven't noticed, Finn doesn't look that different from you or me. Except he's not dead or made of bubblegum."
"Clearly you just don't understand—"
"You just want to see his hot bod!"
"You think you have everything figured out, Marceline," said Bubblegum as she shook her head.
"Because I do," Marceline answered with a smile.
"But you were wrong about me and Finn…"
"Well I'm right about this."
"No you aren't."
"I guess I'll just have to enjoy this delicious sight all by myself," Marceline sighed.
"But they're my binoculars! Give them back!"
"Not until you admit why you really want to check out Finn. No more of that science and anatomy crap," Marceline said while her eyes were still glued to the binoculars.
"But that is the real—"
"Oh wow! I think he's finally getting hard!"
"Gimme those!" Princess Bubblegum screamed as she yanked the binoculars from Marceline and quickly pressed them to her face.
Sure enough, Finn's penis had become fully erect. It stuck out proudly as the young adventurer continued to wash his golden hair.
"It's beautiful!" the princess gasped. "The foreskin pulls back perfectly, and the glans looks very healthy! The shaft appears to be protruding at a 65 degree angle from the stomach and may be anywhere from 10 to 12 centimeters long!"
"Damn, PB… You're really into this."
"How big was it when it was flaccid?" Bubblegum said in a surprisingly demanding tone.
"What?"
"How small was it before he got hard? Two centimeters? Three centimeters? I need to know!" Bubblegum said with frustration.
"Um…I don't know. It was…small. How should I know the exact length?"
"You're useless, Marceline. I suppose I'll just have to keep an eye on it until it returns to its relaxed state to make a proper comparison. "Small" isn't exactly the most precise measurement to go by."
"But I wanted another chance to look," Marceline pouted.
"You can look again when I've got the data I need."
Behind all of the measurements and technical terms, Marceline could tell the princess was actually enjoying herself. Seeing her blush and smile every few seconds was more than enough to give her away.
"Soooooooo," Marceline said to break the silence. "He's got a nice one doesn't he?" She smiled and nudged the princess.
"Yes he does."
"Have you checked out his ass, yet? It's pretty cute. If you're into that kind of thing."
As if on cue, Finn turned around and gave Princess Bubblegum a perfect view. "Oh my! It certainly looks very…nice." The princess was becoming too distracted to provide a proper description for the shapely little butt.
"Haha! I think we've got ourselves an ass fan here," Marceline laughed. "I'm the same way, PB. But I'd take your bubble butt over Finn's any day." As she said this, she gave it a good smack. She quickly realized that that wasn't the best idea, but luckily Princess Bubblegum was too enthralled by Finn's body to notice.
Feeling the mood starting to change, Marceline slowly took her pants off and began to casually rub her clit through her panties.
"This is the life, PB."
