BUBBLES IN THE TUB.
"HEYAH"
Finn and Jake were in the middle of a fight with a steam goblin, which released puffs of steam through its steam chambers all throughout the treehouse.
"Watch it yo, that stuffs hot"
"Chill Jake, this clown is going down"
Finn leaped off the couch and plunged his new elementalist blade right into it's chest, releasing a massive surge of water to extinguish it, causing it to turn to ash and crust after shooting out a massive burst of steam at him. The goblin collapsed on the floor and Finn sheathed his sword.
"Yah ha, now that was epic"
"Sweet strike man"
"All thanks to this mighty strong beast"
"UHHHH, that's not the only thing mighty strong"
"What dude?"
"Dude, you smell rank from that steam blast"
"Oh come on, it's just sweat"
"No seriously dude, you smell like the swamp kingdom's sewers"
"oh weak"
"Look, BMO and I will take this husk to the gravel kingdom for some spell books"
"Cool I'll come with"
"NO, you stay and take a bath before your clothes rot off"
"Huh, fine but I'm using that anti stench soap lady gave you I don't have to do this again"
"Your still gonna bath if you get dirty, well more that usual"
"Whatevs"
Jake and BMO left for the gravel kingdom while Finn turned the water on and started to peel off his sweaty clothes. Unbeknownst to any of them, princess bubblegum had been secretly watching them since this morning in cloak mode, waiting for an opportunity like this. Despite having to return to normal age to stop lemongrab, deep down she still had strong feelings for Finn, but she had to wait till he was of proper age since making her young again would just result in the same thing over again. So she waited patiently for Finn to be of proper age for what she had planned.( Disclaimer: this is not the equivalent of Finn and an old lady as PB is immortal, and if Rose and Greg could do it, then so could they).
"After all this time, your mine Finn"
Bonnie then walked towards the treehouse as Jake and BMO dragged the goblin corpse away. Once she got to the front door, she used her multiplain scanner and shockwave eradicator to force all astro creatures, hidden mutants, and ice king raiding their fridge from the treehouse. This was an afternoon she wanted without interruptions or peepers.
She slowly made her way up to the bathroom. Thankfully, the bathroom door was open(which makes sense given he was home alone).
Meanwhile, Finn was laying his head back, relaxing in the tub. The soap was working as his stench was almost gone.
"Finn!"
"AWWWWWWWWWWWWWWWWWWW, bubblegum what are you doing here?"
"Finn it's okay, I'm not looking, I just wanna talk"
"Couldn't this wait till after I'm done with my bath?"
"It's far too important, I need this to happen now"
"And what is that exactly?"
"It's a surprise, so I'm gonna need you to make me a royal promise that you won't look until I unveil it okay?"
" I royal promise that I won't look until you say, just be quick okay this is really awkward"
Finn then closed his eyes and made sure he couldn't see a thing. After Finn gave her the thumbs up, she tip toed downstairs and came back up with some romantic candles. She lit them after spreading them around the bathroom so the scent filled up the whole bathroom.
"What's up with perfume PB?"
"You'll see, just wait"
PB then closed the bathroom door so the scent would stay in and closed the shades so know one would see them. And with that, Bonnie proceeded to her final step. She unzipped the back of dress, pushed it to the ground, pulled her boots off, clicking the buckle on her bra which caused it to fall to the ground, and taking off her frilly pink panties.
Once she was fully naked, she poked her head in the water to see that Finn had his legs up against his waist, thus giving her plenty of room in the tub. She then stepped her toes into the bottom of the tub, and proceeded to ease herself into the water until she was in the bath with Finn, with only her cleavage visible.
"Okay Finn, you can open your eyes now"
Finn opened his eyes, and was presented with princess bubblegum naked in the tub with him. Finn was about to scream but Bonnie stopped him by covering his mouth.
"Now Finn, I know your gonna freak out, but just hear me out. Look, I know I've said that our age has kept us from being together, but I realized that I was wrong. I love you Finn, your one of the very few people I've met that understands and cares for me so much. I just wanted to wait until you were ready for this."
She took her hand off his mouth and he answered
"For what?"
"This"
She quickly leaned in for a passionate kiss. While surprised at first, Finn returned her love and leaned in to deepen the kiss. Bonnie then pressed and started rubbing her chest against him, sending chills down his body and causing his body to warm up all over. The two moved closer until their genitals were rubbing against one another as their kissing grew deeper and deeper. After about 3 minutes of kissing, PB moved towards the edge of the tub and pulled out the drain plug. Finn noticed this and quickly plugged it up with his butt.
"Finn, what are you doing?"
"What are you doing, if you drain the water then..."
"we'll see each other naked"
"Well yah"
"Finn, I understand if this is all new for you, but I want to give you the ultimate feeling of love and pleasure, and your gonna need to move your butt in order for that to happen"
"It's just, I don't know if I'm ready yet, what if I mess up or hurt you or..."
"Finn, I know your ready, that's why I waited this long. I know that your ready Finn, and that I trust you completely to do this , but do you trust me?"
Finn long hard about if he trusted her THIS much. After a few minutes, he finally let out a sigh and moved away from the drain, letting the water lower.
"You made the right choice Finn."
Finn was started to feel warm as they water was draining more and more. Bonnie started to move closer as the water was kept draining. Both Finn and PB starred in awe at the others exposed naked body.
PB looked on at Finn's chizzled chest, 6 pack stomach, firm shoulders, surprisingly smooth skin, sculpted rump, and massive 11 inch groin.
Finn looked on at PB's baby soft skin, wide hips, hourglass figure, slim shoulders, shaven cave, double E breasts, and a massive, round, soft bubble butt(of course).
"You look amazing Finn"
"You to, just wow"
Bonnie noticed where Finn was specifically gawking at
"You like my butt don't you?"
Finn blushed after she said this
"Uhhh, yah."
"Thanks, do you wanna...squeeze it?"
"Wha...you mean it?"
"That and so much more, come here hero"
PB brought Finn in close for another kiss. As bubblegum wrapped her legs around his waist, Finn moved his hands down her back and proceeded to grab and squeeze her bubble butt. PB let out a slight moan in his ear in response. After a few minutes of kissing, Bonnie broke the kiss and looked deep into Finn's eyes.
"Finn, you can go inside me now, I'm ready"
"Okay, lets do this"
Bonnie leaned against the edge of the tub, Finn steadied himself on top of her, positioned his crotch against her labia, and dove right into her. Surprisingly, he didn't feel any barrier or resistance.
"What the..."
"Remember Finn, I'm a mutant, I wasn't created with human features like hyphens, which helps out."
"Oh, okay"
Finn then immediately went to work. He started thrusting slowly, letting PB savor every moment. PB was starting to moan again. Finn then proceeded to increase his speed, causing PB to slide back and forth a bit due to the wet tub. PB wrapped her legs around his waist again, causing him to thrust a bit harder. Finn then started to simultaneously massage and dig his face into her boobs. Bonnie's moans were starting to get louder and louder. Finn was getting so passionate that he started to thrust harder into her. Bonnie was sliding so much that her back was practically cleaning the tub.
"Ooooooooohhhh Finn, yes, oh yes"
PB's moans were getting so loud that it could break glass. Finn massaging her boobs were making her feel even more tingly. Bonnie was holding him as his thrusts were getting even faster and deeper. Bonnie was gripping onto the sides of the tub as she was about to reach her climax.
"Finn, I'm gonna aaaaaaaaaaaaahhhhhhhhhhhhhhhhhhh"
They had both reached their climaxes and Finn passed out, his face landing on bubblegum's breasts. Bonnie then pulled him in for a hug and fell asleep with him in the tub, whipping out a smile for the best mate she had ever been with.
