It had been over a month since Gumball Watterson and Penny Fitzgerald had their first hot experience in diapers together. Ever since that fateful night, the young cat and shapeshifter had dreamed nonstop about doing it again with each other. As badly as the two lovers wanted to do it though, between school, misadventures and their parents being home a lot more than usual, they just couldn’t find the perfect time for it. Also, since both their parents had been somewhat intrusive on their personal lives lately, it didn’t make the possibility any easier. But even so, they didn’t give up hoping, dreaming and fantasizing about seeing each other again in private and getting frisky in their puffy undergarments once more.

It was a sunny Friday afternoon. Gumball and Penny stepped off the school bus, and onto the sidewalk near the Fitzgerald house. As the blue teenage cat stepped onto the curb after Penny, he spoke in a huffy tone. “Jeez, Pens. Couldn’t Ms. Simian give us any LESS homework than she normally does? I mean, come ON! A five-page report on the War of 1812 by Monday morning? I can’t even finish half a page on why soap has many different scents in a week!” Gumball complained. “Well, maybe you should start actually DOING the homework for once? Maybe that could help.” Penny smirked as she helped Gumball balance the heavy textbook he was carrying. Gumball gave Penny a poker face. “Rigggghhht...”

As the two made their way up the steps to the porch of Penny’s house, the two noticed a note on the door. Penny and Gumball gazed over the note. They recognized the handwriting as Mr. Fitzgerald’s.

Penny,
I’m going out with the Wattersons this afternoon for poker. I should be back by no later than 6. I’m trusting you will behave while I’m gone. 
By the way, if you bring that boyfriend of yours over, PLEASE do not burn the house down again.
Love you, sweetie!

Penny and Gumball’s eyes gazed at each other’s, and they grinned. “Heh, you know what this means...right, m’lady?” Gumball grinned warmly to Penny as she started to blush and glow warmly. “Oh, you bet, my little Gummypuss. We can finally get some alone time…” Penny leaned into Gumball’s ear and whispered, “...in our...diapers.”  Gumball’s fur immediately stood up on end, and blushed heavily upon hearing that certain d-word he loved so much. “Oh, HECK yeah! Um, I mean...I’d love that, Penny. It’s been SO long.” “Heh, only a month, silly.” Penny giggled as she unlocked the front door of her house with the spare key she kept in her backpack. “I guess that homework will have to wait.” Gumball grinned as the two made their way into the house. 

After making their way to Penny’s bedroom, Gumball immediately dropped his backpack and red-and-white letter jacket on the floor. “So, Pens. I trust you still have the ones I lent you from my place after last time?” Penny blushed. “Yeah. I’ve hidden them quite well from dad. And, I still haven’t used a single one yet, since I’ve been saving them for such an occasion like this…” Penny giggled sweetly. “Now you get undressed, and I’ll get them out.” Gumball winked ‘yes’.  Penny went over to her closest as Gumball began to strip down naked.  “Found ‘em!” Penny exclaimed as Gumball finished pulling down his pants and tighty-whities. The blue teenage cat turned his head to see Penny holding two diapers in her hand; the same kind from Gumball’s house. “Good searching! And...perfect timing, too. As you can see…” Gumball pointed to his twitching erection. He was already getting extremely horny, and Penny smiled at the sight. “Oh, Gummypuss...you’re so cute when you’re horny like that...would you like me to diaper you this time?” Penny felt her loins tingle as she handed Gumball his diaper. “Heh, no thank you. I can handle it. I'm big enough.”  Gumball said with confidence. Penny snickered, “Heh, suuuuure you’re big enough. Says the cat who acts like a kid, and wears these things.”

Gumball frowned, unamused at his girlfriend’s wisecrack. He then quickly smiled again after grabbing the diaper. He unfolded it and opened it up, and as he held it in his hands, he gave the inside padding a long, deep sniff. The smell of the fresh baby powder in the padding made his dick twitch, and leak a drop of pre onto Penny’s rug. Not that Penny really noticed; she was too busy focusing on changing into her own diaper. After the two horny teens were padded up, they stood up to face each other. They looked each other in the eyes with total lust, and without saying a word, they immediately ran into each other’s arms and began to make out furiously.

As the two French-kissed, Penny slipped her hand into Gumball’s diaper waistband. She touched the young blue cat’s hard cock in his soft padding, and he moaned upon the touch. “Oh, Penny... your hand feels so good on my penis!” Gumball moaned in pleasure as Penny continued to fondle his pulsing member. “I bet it does, my sweet, little Gummypuss.” Penny smiled as they continued kissing. She began to slowly stroke Gumball's erection. “Mmmmm, you’re so cute...It seems only fair that I rub you as you rubbed me last time.” Gumball giggled a bit, his legs quivered from the sheer amount of pleasure he was receiving from his girlfriend. “Goodness, Gumball! Your legs are shaking quite a bit. Should I stop?” Penny looked down at Gumball's legs, which were shaking a lot more now. “N-No, P-Penny...I-I’m fine! Keep going; I just love it so much!” The blue cat moaned as his mouth hung open.

“Oh! Wait...I think I’ve got something a little better than this…” Penny quickly yanked her hand out of Gumball’s diaper. “Just lay down on the bed, and wait patiently.” Penny crooned as she pushed Gumball onto her bed. As she waddled towards her closet again in her diaper, Gumball began to get some serious sensual hunger. Just the sensation of Penny rubbing him off in his diaper earlier made him want to climax on the spot, but he decided to be a gentleman and wait to see what else she had in store for the horny blue cat. “Aha! Here it is!” Penny said excitedly as she pulled out the object that she reached for. “Yo! Is that a massage wand?” Gumball blushed as he caressed his crinkleboner. Penny giggled, “You guessed it, hot stuff. I’ve been waiting for the perfect chance to use this thing on you…now lay down, Gummy.” Gumball’s thoughts jumbled. “Oh, my god!! Penny’s gonna vibe my diaper!! I...It’s gonna feel amazing!!” Before he could finish his thought, he heard the wand click on, and a low humming noise followed. “You ready, handsome?” Gumball responded with a thumbs-up. 

Penny pressed the buzzing ball of the massage wand against Gumball’s diaper tent, and the blue cat immediately let out a loud, pleasurable moan. “OOOOOOHH!! That feels so good!! Keep going, Penny!!” Penny nodded, slowly rubbing the massage wand up and down on Gumball’s padded member, the vibrations sending waves of pleasure throughout his entire body. “Hehehe, you like that, don’t you Gumball? Want me to crank it higher?”  Penny asks lovingly as she teases Gumball a bit. “O-Okay...p-please do that...” Gumball bit his lower lip and braced himself. Penny then clicked the massage wand to the highest setting, and it began to vibrate Gumball’s entire diaper. “OOOOOOHH, YEEAAAAAAHHH!!!!” Gumball moaned loudly once more as the vibrations spread around his entire crotch.

Penny giggled. “You love that a lot, don’t you, Gumball? Hmm? Do you love it?” Penny smiled, using her free hand to pinch the blue cat’s blushing red cheek affectionately. “Mmmmff! I love it so much; it feels awesome! Oh, GOD, Penny!...” Gumball moaned and squirmed in pleasure as the vibrations continued. “You ready to release big stickies into your thick...puffy...pamps?” Penny teased Gumball as he reached the point of no return. “Y-Yes!! I wanna squirt so bad!!” Gumball squealed a bit as he used his hands to press the vibrator harder onto his crotch. Red hearts flashed in his eyes as he felt the intense leadup to a glorious climax. “Well, then go for it, Gum-butt. Show me how much you love your diapers!” Gumball clenched his teeth and thrusted upwards against the wand’s end. With a long, loud grunt of euphoria, he came hard in his diaper; the fabric of the diaper became wet as it soaked up his sticky spunk. His repeating groans were like music to Penny’s ears, and she gazed at Gumball’s twitching diaper tent with love in her eyes.

“He’s so cute when he squirms like that…” Penny thought to herself as she clicked the wand off. As soon as she did so, she could hear Gumball’s intense orgasm coming to a close. “Oooough...Oh, man…” Gumball huffed and panted as he embraced his afterglow. “Penny...that felt sooooo good…” Penny giggled as she took the wand off her lover’s sperm-stained padding. “Of course it did, Little Gummypuss. I figured you'd enjoy that.” Gumball collected himself, sitting up on Penny’s bed. “Oh, man...I’m so wet…” The spent blue cat huffed as he groped his soaked padding. He then leaned in to kiss the glowing shapeshifter on the cheek. 

“Aw, you’re so sweet. So, are you all empty yet? Or would you like some more?” Penny grinned. Gumball smiled with a lustful look. “Actually, I had something in mind that I’ve always wanted from you, m’lady.” The padded blue cat rolled onto his front, making his diaper squish lightly. He then got on his hands and knees, and lifted his padded rump to face Penny. As he turned his head to look behind him, he noticed Penny was slightly rubbing her padded folds. “Heh, you really like the view back there, don’tcha?” Penny quivered, “Y-yes…” She leaned in to press her face into Gumball’s diaper seat. She gave the padding a long, heavy sniff, and exhaled shakily, muffled by the padding. As she did so, she could swear she felt her pussy tingle and get wet, the fluid getting absorbed by the cotton.

Gumball laughed slightly. “Heh, since you like my diaper butt so much, Penny, why don’tcha get up here and hump it? In fact, that’s what I’ve wanted from you since our last time doing this! C’mon! Pound me, Penny!” Gumball said as Penny unpressed her face from the blue cat’s seat. “Honestly, Gumball...you never cease to surprise me.” The shapeshifter floated up behind Gumball, and stood firmly on the bed to get into a doggystyle position. As Penny grabbed Gumball’s waist from behind, her diaper pressed firmly into Gumball’s. A loud crinkle of both their diapers touching filled the lover’s ears. Penny shivered upon the touch, her inner padding stimulating her tingling clitoris. Gumball snickered, “I bet you won’t last more than three minutes humping me! But then again, I probably won’t last long, either…” Gumball thought aloud. “Aw, what the heck! Just grind me already!” Gumball braced himself for the padded humping of a lifetime.

Penny then started to hump Gumball’s padded rump. She moaned softly with a shudder as she thrusted repeatedly. “Oh god Penny that feels so amazing, k-keep going my love!” Gumball huffed as Penny continued to hump his padded butt. He gripped onto the bed sheets and bit onto his lower lip. Hearts appeared in his eyes as they rolled back into his head. Each thrust sent a wave of pleasure through both Gumball and Penny’s body. “Oh god, Penny...keep going, you’re doing g-great! N-Nyaaaahh!...” Gumball moaned loudly as Penny continued to grind his diaper seat. “Mmmmnnn... this is so much better than last time...I love this so much, Gummypuss!” Penny groaned. Gumball responded with, “Mmmmm, oh, GOD, Penny! That feels so g-good! Our diapers are touching and you're grinding on me; I’m SO in heaven right now!!” Penny smiled upon hearing her lover getting sexually satisfied. It was a dream come true for Gumball, and if this was a dream, he would never want to wake up.

All of a sudden, Penny stopped thrusting into Gumball’s padding. He shakily turned his head behind him to face his girlfriend. “Penny? Why are you stopping?...I want MORE!” The horny cat huffed with desperation, his face all red with warm blush. Penny chuckled with a dominating gaze. Gumball’s eyes widened with surprise as Penny suddenly flipped him onto his back without hesitation. “Gummypuss…” She crooned as she sat herself on Gumball’s tented diaper front, getting into the reverse cowgirl position. “My libido has NEVER been this high for you before...you look so...fucking cute when you squirm helplessly for me!...” Penny said as she glowed brighter than previously. Gumball shuddered, “Penny...l-language!...” Penny responded by roughly grinding her diaper on Gumball’s. “I’m sooo sorry, Gumball…but I need to do this...I wanna cream...so...FUCKING...bad!” Penny groaned roughly as she slid back and forth on Gumball’s puffy crinkleboner. “Aaaanh! Penny! Please don’t stop! Yes! YES! YESSS!!”

The blue cat’s mouth hung open, drooling slightly from all the stimulation he was receiving from his extremely horny girlfriend, mixed with the softness of his diaper. The spunk that soaked his diaper from his previous orgasm acted as a lube, making his twitching cock more warm and wet. Penny, at the same time, was also starting to get wet with arousal in her diaper; her grinding against his boyfriend’s padded bulge rubbing against her quivering clitoris. “Uuuugh...Gumball...I...I love you!...I love everything about you!!” Penny squealed in excitement as she grinded faster on Gumball’s diaper, rocking the bed back and forth quite violently. Gumball yelled back to Penny, “I...I love you...t-too! OOOOOHHH!!” The two lovers gazed into each other’s eyes with passionate love as they reached the edge. “PENNY! I...I’M CUMMING!!” Gumball yelled in euphoria. “ME TOO, GUMMYPUSS! OH, MY LOVE!! CUM IN YOUR DIAPERS FOR MEEE!!!” Penny screamed. After a long, loud yell from both of them at the same time, the two diapered lovers finally had what probably was the longest, greatest and most intense orgam they have ever had in their young lives. Gumball’s legs flailed as his cock spurted huge streams of his seed into his diaper, once again making it wet, slick and warm. Penny’s folds pulsed as she spilled heavy amounts of her fluids into her diaper, and each pulse rocked the female shapshifter’s body like lightning. Heavy crinkles, spurts and moans filled the room with an intense volume. After about ten more seconds, their climaxes had finally come to a close. “Oh Penny...my love...that felt amazing...” A wide, stupid-looking grin spead across Gumball’s face as he gazed up into Penny’s eyes. “It certainly did feel lovely, my precious Gummypuss... I love you so much!” Penny collapsed onto Gumball’s body, exhausted from her intense diapergasm. The two then went in for a long, tender kiss on the lips. It felt like the most sincere kiss the two had ever had in a long time.

During the kiss, however, Gumball’s eyes abruptly widened and he pushed Penny out of the kiss. He had just seen  something that made his blood run cold. “AAAH! MISTER FITZGERALD!!” To both Gumball and Penny’s horror, Mr. Fitzgerald was standing right at the end of Penny’s bed, completely blank-faced at what he had just witnessed. “DAD! Please! It’s...It’s not what it looks like!” Penny frantically tried to cover her wet diaper up with her pink pillow. Gumball started to scream internally. Mr. Fitzgerald just kept staring at the two in utter shock. Not in anger or disappointment; just total body-numbing shock. The two sheepishly stare at him, blushing a heavy red with complete and utter embarrassment. After ten more seconds of insanely awkward silence, Mr. Fitzgerald spoke quietly in a calm voice; so calm, that it was actually haunting to hear. “At least you two didn’t burn the house down this time...” After breaking the silence, Mr. Fitzgerald walked out of the room. He had a lot of thought processing to do. Just as he walked out of the room, he could hear Gumball’s voice sheepishly call out to him. “So…Uhhh....how did the poker game go, Mr. Fitzgerald?...” The shapeshifter’s shaken father responded with, “I...had a good hand...A full house...Jack’s high.”
