That day was going to be a long one, Pearl had planned that day to go to Mrs. Puff's house for some hanging out and workout sessions, it would be cool to do something else besides shopping. And with her trusty slave Spongebob now in the shape of a towel, was hanging by the hangar where Pearl put him there, he watched as she began to put her outfit on, struggling to do so. The yellow guy couldn't help but giggle quietly at how difficult it was for her to put her pieces of clothing due to her phat ass.

'Even as the *greatest whale of all time, according to her* she still struggles with her outfits' He said quietly, knowing that if Pearl heard what he said, he would be punished.

"God fucking damn it! By Neptune's beard, when will people make clothes in a size that fits me well like a glove?!" She screams.

"Need any help?" Spongebob asked while laughing.

"Bet you're having fun at my expense huh?" She now looked at him.

Spongebob realized his mistake as he looked up to Pearl and gulped. "Ummm, I-" Before he could say anything, Pearl grabbed the towel sponge and scrubbed him between her sweaty butt cheeks after he was soaped up.

"Hmm~Let's see if you can lose things up for me a little," She said with a smirk making him slide across her meat buns.

While Spongebob was getting scrubbed between her butt cheeks, he was just happy that she didn't put him inside of her asshole instead. After Pearl finished, she could see her sponge slave's dizzy face once she got him off her ass.

"Thanks for lubing up my cheeks you sissy. Now I can put my pants much better now that they are slippery" Pearl laughs.

"Y-you're w-welcome," Spongebob said, still dizzy from that ass rub. Pearl then puts him back on a hanger and puts her pants on. After Pearl got dressed, the sponge slave's eyes widened and could see Pearl's sexy outfit.

"Ahhh much better! How do I look?"

She showed off her workout clothes which were purple yoga pants with black lines and a sleeveless white shirt. All of them hugging her body in a form-fitting style.

"Y-You look amazing!"

He said, being serious and hoping that Pearl wouldn't punish him. Pearl smirked, knowing that her body would forever be the enemy of the sponge.

"Good to know no matter how many times you see this ass you don't get tired of it. Get ready Sponge, today we are going to your former driver school teacher home"

Spongebob gulped but nodded in defeat to please his mistress, who smirked and put him between her ass cheeks. Spongebob didn't want to go to his teacher's house. It was bad enough that he got her in trouble for things she didn't do. If she sees him like this, he'll be dead. Pearl, on the other hand, didn't care, as she wanted to torture him for being an annoyance to her every single time.

"Enjoy the butt ride in there Spongebob. I will do some running to her house and warm up before we can have some real fun today haha!"

Pearl started to jog while Spongebob could only muffle thanks to her ass being too big for his words to make any sense without being stopped by such flesh.

*Mrs. Puff House*

While that was happening our favorite teacher was getting nervous since Pearl is coming to her house. Ever since she told her that she was bisexual, she started sweating while putting her outfit on. She was just happy that this is just a one-time thing...Or was it? That's when the doorbell rang.

"Ohhh, she's here!" Puff said, getting ready. Once she got dressed, she went to the front door and opened it, revealing a very hot-ass Pearl.

"Hey there, I sure hope I'm not too late for our get-together" Pearl gave an innocent smile.

Mrs. Puff was sweating, even more, checking out Pearl's hot body with desire "O-Of course not, Pearl. Come right in." She said, trying to sound as normal as possible.

"I hope you are ready because today we are doing it hard...exercise right? You wanted a little of that?"

"Of course. let's get started!"

Pearl walked inside, while purposefully shaking her ass back and forth for all to see and to torment her sponge slave and tease Mrs. Puff

'Fuck...That Damn cake' The driver's teacher said, biting her lower lip.

"Nice place you got here, I like it," Pearl said, sitting on a chair specially made for big assed ladies.

"T-Thanks"

"How about we put some songs up and ready?" The whale asked.

"S-Sure," The puffing fish said, turning on the radio.

Once the music started playing (Insert favorite workout song here) the two big-ass women were doing squats first. Mrs. Puff was in front of Pearl so whenever she went to do her squats, it was impossible to not look at Pearl doing hers, and every time she bend over it was like her but got even bigger. The puff fish really wanted that WHALE BUTT, but she didn't want to anger her, remembering that the wrong crowd made the whale ticked off and blamed her student so they could get away with it.

Pearl looked behind her and smirked evilly, knowing that the puff fish was staring at her ass, who wouldn't? All she has to do now is wait for the right moment to strike.

"Once we are done how about some sit-ups? Gotta work to have a sexy six-pack too" She laughed off.

The Puff fish chuckled nervously. "Y-Yeah. Let's do that"

'Ughhh...it's getting so sweaty and humid in here' Spongebob grunted.

The Sponge was getting every drip of whale sweat inside of him and he couldn't take it anymore. Luckily for him, after ten minutes, the women stopped doing sit-ups. Then they would go for push ups where Mrs. Puff would have to do push ups when Pearl was on top of her, just barely since Pearl didn't want to squash her, but the lust the pufferfish felt gave her strength, to feel such a glorious ass was a given, later on, they would switch spots.

"This was a nice workout don't you think?" Pearl asked.

Mrs. Puff looks the other way, trying not to stare at her tits "S-Sure is"

Pearl took the chance and removed Spongebob from her ass who just casually had been turned into a towel "You must be sweaty huh? Here have my towel" She smirks.

The puff fish grabbed the *Towel* "Thanks, Pearl." Mrs. Puff said, using it to get the sweat off her body. SpongeBob, couldn't believe this was happening.

Pearl was quietly laughing her whale ass off in her mind 'Oh my gosh! Look at how she is rubbing her chest with him. Man if only she knew, I bet Spongebob likes the ride'

While was using said towel she had to admit, it looked familiar, but it didn't get to her head. Once she finished, Mrs. puff used it on her arms, her armpits, legs, and finally her fat ass.

"Oof! This might sound weird Pearl but your towel really knows how to take the sweat away and it gets into the hardest parts to reach" She said enjoying it.

"Yeah...you can say it is quite absorbingly wise" Pearl smirks.

"Ha, I guess so," Puff said, enjoying the towel she's using. Once she finished, she gave it back to the whale.

"I'm glad you enjoyed it. Now how about I go grab us some water bottles?" Pearl said, putting the towel on the couch.

The thicc whale then heads to the kitchen opening the fridge, while taking a quick look before landing her phat ass on the couch and landing right on the *towel* Spongebob could barely breathe before and now? Even less.

Mrs. Puff kept staring at that huge whale ass while sitting and waiting. She could see why Miles had an innocent crush on the whale. Looking down, she realized that the towel she was sitting on reminded her of something.

'Hmmm...I can't shake this odd feeling about this towel...besides being comfy of course'

Back with Pearl. she had got the water bottles, throwing one of them at her friend who secretly wanted to have an adult fun time with her. She caught the bottle.

'I hope you're enjoying that ass Spongebob. Because I know what that Puffer of a woman truly wants' "Kept you waiting?"

"Thank you, Pearl." Said the puff fish. She scooted over so Pearl can have a seat on the other side of the couch. 'Look at that WHALE body. I would do anything for that ass' Puff said internally.

'I bet it's killing him to not scream right now, having two big girls like us sitting on him on this couch' "Man it's so hot today" Pearl said letting some of her water bottles fall on her skin by 'Accident' "..Awwwn much better" She made sure to moan seductively.

Mrs. Puff heard her moan and gasped a bit, but Pearl didn't care. However, staring at the whale, she couldn't take it anymore so she did a bold move and kissed her cheek.

'Oh shit! Did I do that? Great, now Pearl is going to kill me because I can't keep it in my pants' Puff said internally. However, while the pufferfish wasn't looking, the whale had a sexy smirk on her face, forming a naughty idea.

"Oh my! Did you just kiss me ?" She made a fake look of shock "So...naughty of you"

"S-Sorry, Pearl. I-It's just...You're so hot and sexy. And THAT HUGE WHALE ASS you have. Any woman would do anything to worship it!" Puff said, admitting her feelings to the whale.

"Is that so? Then allow me to make your dream true"

Pearl then grabs by the shoulders and kisses her too, but this one ain't a shy one in the cheek like the one the women did. No, this one was a full-blown adult kiss where Pearl made sure to show her that the whale meant business. Their huge tits smashing against each other like two huge pudding-filled pillows.

"MMMMMM~" The puff fish moaned, kissing back the whale. She couldn't believe this was happening, yet she was too horny to care. She put her hands on Pearl's ass.

"You want this ass, don't you? How about we drop on the floor and have some fun? This couch ain't big enough for us both to get more into it" Pearl said with a giggle.

"Of course, sexy~" Puff said, getting on the floor with Pearl, still kissing her lips and rubbing her ass.

Spongebob gasps for air, now finally able to move around as his head is all dizzy he still manages to look around and see what is going on on the floor.

'Holy Krabby patty what is happening?' He said in shock.

Spongebob couldn't believe that his own boating school teacher was having a make-out session with the whale who was tormenting him. He had to admit, it was kinda hot.

"Oohhh god your ass is amazing!" Mrs. Puff said as she removed Pearl's yoga pants off letting her meat buns out before groping them fiercely like dough. "I bet it tastes good too"

Puff started kissing the whale's ass cheeks, wanting the taste so bad. Spongebob almost thought of getting out of here, but he wanted to continue to watch the show.

'Hmmm...maybe I can enjoy the show after all that struggle' He told himself and kept looking at how she had fun.

Mrs. Puff continued to kiss Pearl's ass cheeks until she got started in licking her ass crack and sniffing it.

"Whoooaa! You are such a pervy. You're treating my ass like your toy huh? Geez, what if anyone saw you like this? Hehehe"

"I would do anything for this ass, Pearl...Anything" Said the puff fish, starting to rim her tongue in pearl's sweaty ass hole.

"OH MY!~" Pearl moaned in surprise by her bold move, enjoying it as she let it happen. Maybe after that, she would help her with it too as well.

*Two hours later*

"Phew...I can't believe I have done all that. We even had a shower together '' Mrs. Puff said, now in her extra Neptune size bed with Pearl.

"Me neither, it was quite enjoyable," Pearl said, smirking. Her plan was almost complete. "Pearl, I'd do anything for that ass of yours" She repeated.

"Please don't say that out loud" The pufferfish blushed.

"After groping, slapping, and biting my ass on the shower? I guess not"

Mrs. Puff blushed again, hugging Pearl and kissing her lips. "I can see why Miles likes you. Too bad he doesn't dare to ask you out."

"Give the guy a break, we met for like three minutes" Pearl then wonders if Spongebob was still on the couch, she was so busy having a fun time she forgot about him.

Back with Spongebob, he got out of Mrs. Puff's house and tried running away. Of course, he didn't get far because he coincidentally tripped over a rock.

"Ah, shit!" He said falling down.

That's when someone came along and helped pick him up "Are you okay, sir?"

"Yeah I just tripped on a rock that's all," Spongebob said, getting up.

"Well, at least you're not hurt too bad. "The name's Miles"

"Hey there kid, sorry if I'm being a bit of a prick but I gotta get going"

"Why? You're running away from a monster or something?" Miles asked curiously.

"You could say that" Before the sponge could run, Mrs. Puff yelled out their names from the window.

"SpongeBob! Miles! Hello, boys!"

"Oh hey, it's Mrs. Puff, Hello there!" He waves innocently.

SpongeBob saw his teacher and also waved at her. "Oh...hey"

"Are you running from her by any chance?" Miles asked.

While Spongebob technically was running away from his teacher, he was mostly running away from Pearl. However, he didn't want to scare the kid. Before he could say anything though, she needed them for something.

"Well..." Spongebob was about to say until the puff fish said something.

"Spongebob, Miles, I want to give you two something," She said.

'Fuck!' "Uh...What would that be?" Spongebob forced a smile.

"Come at the front of the house, and I'll show you," Puff said. As much as Spongebob wanted to get out of the area as soon as possible, he didn't want to give his teacher a hard time, so he and Miles did what she said. Back with Pearl, she was looking for her sponge, remembering that she left him on the couch. She was now very ticked off.

"Where is he?!" Pearl said, very ticked off that she couldn't find him. That's when she sees downstairs, heading to the front door. "Ohh hey puff, who's at the door?"

"Spongebob and Miles" She answered.

Pearl was ticked off that Spongebob tried to run away from her, but she couldn't show it to so she put her innocent look on "Oh, the sponge and the boy who had a crush on me?" She asked. "Yep," Mrs. Puff said.

Spongebob and Miles waited for them at the door. Finally, Mrs. Puff opened the door "Here you go, boys" She said, giving each of them a driver's license. "Thank you, Mrs. Puff!" Miles said.

"Whoa! I really got one now? Awesome" Spongebob said happily.

Spongebob was about to get away as if nothing happened until Pearl came out of the house "Ahem! You don't think you can leave without me right? We have unfinished business" Pearl said.

"Oh...crap"

"See you later Miles," She said, while grabbing Spongebob's hand and patting Miles' head.

Spongebob was so close to having freedom. However, fate wasn't helping him at all.
