Hot Tub, The

NOTE: This story came from me and my wife’s experiences and experimentations with her wearing a tankini in a hot tub, and how she makes herself inflate in it. Read my posts detailing our fun in the forums under “Swimsuit inflation in all the right places.”

“I know that you get a kick out of it,” she said with a mischievous grin. “I don’t wear my other swimsuit sometimes, because I know that it happens only when I were this one, and what that does to you.”

Jack returned a knowing smile. In fact, he had anticipated what she would do, and had made his own preparations. And his actions were just about to bear fruit.

Trish had surprised her husband with a new toy for his birthday. The backyard, with its tall, full trees that offered seclusion, was the perfect place for such a gift. It was something that both of them had always wanted, and when she got the chance and the finances Trish couldn’t pass up on the deal. While Jack had been at work the day before, Trish had the hot tub delivered and set up on the deck that overlooked their backyard. With the fence and the high foliage, they could be naked and doing all kinds of adult activities in the tub without the neighbors ever seeing anything, and that was what Trish had in mind for later. But for now, she wanted to fulfill another of her husband’s fantasies for his birthday.

They had done a lot of traveling in the past two years, since the last of the kids had moved away or gone to college. Lots of hotels and motels meant lots of pools and hot tubs. And Jack’s favorite thing to do was to get Trish into a hot tub and get her to inflate her swimsuit. She would wear this one bright-colored tankini that was loose enough to allow some of the bubbles from the jets to collect under the top. It would make her look like she was pregnant and growing when the bubbles congregated in the lower half of the tankini top. Sometimes she would hold the sides of the top down so that it caught and held a lot of air, blowing her up to about six feet around the waist, so much so that she would float off the hot tub’s seat. But her favorite thing to do was to push down on the abdomen of the suit and force the air to bubble up into the lined breast cups. They would bulge out like balloons, making her chest appear thrice her natural size. Trish would allow them to inflate and then play with them seductively, or allow Jack to play with her breast balloons, as long as no one else was in the hotel’s pool area.

So now they had their own hot tub, and could do the same whenever they wanted to. And both had plans for the first dip into the new Jacuzzi. Little did they know that the confluence of their individual actions would have such interesting results.

Trish didn’t know it, but she had accidently left a clue, a hot tub manufacture’s catalogue, tucked into her bedside table. Jack had found it, flipped through it, and saw one particular model circled for emphasis. He deduced what she was getting him for his birthday, and why, and had made a little preemptive purchase of his own. He found a breast enhancement powder that could be sprinkled onto a woman’s chest for absorption, but would remain inert until activated by exposure to water. On the morning of his birthday, after her shower, he sprinkled the powder into the cups of the white bra she would be wearing that day, and he did the same into the cups of her tankini.  And he waited, practicing his fake reaction of surprise when she would show him his new birthday toy, and wait for the real show to start.

Trish had met him at the door, wearing a long fluffy robe and nothing but a silky red thong underneath. She served him his favorite dinner while wearing only that, swatting his hands away anytime she caught him reaching for an exposed breast. “You’ll be doing lots of that later,” she purred. After dinner, she put a blindfold over his eyes, and instructed him to wait while she changed. He sat in silence for a few moments until he heard the soft rustle of a satin robe as she walked back into the room.

“I’m going to take off the blindfold,” she whispered into his ear seductively, “and then I am going to hand something to you. I want you to put it on, and then follow me.” Slowly she remove the necktie she had used to blindfold him, and handed him a new pair of swim trunks. The color and print matched the old tankini she was wearing under the beach cover-up robe.

Jack raised an eyebrow in mock surprise. “You want me to put on a bathing suit?” he asked, trying to suppress a smile. “Are we going swimming?”

 “In a manner of speaking,” Trish answered, her eyes smoky with lustful anticipation as he changed out of his work clothing and into the trunks. “Now follow me.” She pretended not to notice, but his new suit was already tenting as his flagpole became more prominent, rising in anticipation of what was to come.

She led him out the back door and onto the cement patio that overlooked their yard. The sun was still high for a summer evening, but the shadows of the tall trees had almost reached the new hot tub. It was turned on, bubbling and fizzing, with a light mist rising from the surface of the warm, agitated water and illuminated by the submerged lights of the pool. Jack bellowed with delight, and grabbed his wife in a not-so-fake passionate embrace with a long, deep kiss. She leaned into him, feeling the hardness of his desire, and after a moment was forced to brake the embrace. “Let’s get in,” she purred, peeling off the silk robe and allowing it to drop, fluttering to the patio. Trish took him by the hand and led her husband up the fiberglass steps.

They both settled slowly into the tub. It was big enough, and had seats carved into the case, for six people. The sides had jetted air outlets that would hit a person in the upper and lower back, but also had a stream shooting from a spot in the middle of the seat.  The small jet bubbled between his legs, tickling Jack’s nether region delightfully. He watched his wife slowly sink into the hot, steamy water, almost up to her shoulders, and he waited with a mischievous smile for the show to begin.

With the touch of the hot, chemically treated tub water, the double dose of powder that had absorbed into her skin began to unknowingly take effect.

“I want to blow up for you,” she cooed, reaching a foot across the tub and touching his inflated crotch. “I know that you get a kick out of it,” she said with a mischievous grin. “I don’t wear my other swimsuit sometimes, because I know that it happens only when I wear this one, and I know what that does to you.”

With the jet bubbling vigorously between her own knees, Trish pulled the bottom edge of the front of her tankini forward to capture the air, and she began to grow. The loose part of the swimsuit began to expand and round, looking like she was inflating a beachball under it. She held the sides down to hold the accumulated air in, straining to keep it from exploding outward into the water. Some of the air leaked into the bra cups, and she began to gain there as well. She started rising upward as the air pushed her higher above the surface of the water and off the seat. Trish giggled as she bobbed momentarily like a cork in the water, bigger around than she had ever been before, to the stunned amusement of Jack. Then she let go of the stretched out tankini, the air and water spraying his face as it burst from under her suit, and she dropped back into the seat.

“That was fun!” Trish declared, wiping a wet lock of dark hair from her eyes. “I think I’ll do it again.”

“Can you get any bigger?” Jack challenged, smirking.

“We will just have to see,’ she said back, pulling down harder on the tankini’s fabric. Slowly Trish began to blow up again. Bigger and bigger she grew, her backside floating off the seat again. Air was bubbling around her breasts as the cups were its only outlets, tickling her engorged nipples as she strained to hold in as much air as she could. She was practically standing upright, her feet barely touching the bottom of the tub as she bobbed like an inflatable pool toy. Finally unable to hold it anymore, she popped like an overblown tire, sending water spray and a rush of air outward, and she splashed back down into the deepest part of the pool, practically landing in her husband’s fully aroused lap.

Touching him there again, Trish purred “So, Jack, is that a blimp in your shorts, or are you happy to see me?”

He sat there, shaking the water off his face, stunned, having never seen the sex kitten side of his wife on display so bluntly. “Yes, it’s a blimp down there, a long fat one!” he growled lustily.

“Well, if it gets any bigger, you are going to be floating like me!” Trish sat back in the seat opposite him again. “And speaking of blimps, watch this…”

She leaned back, resting against the blow of the jets, the very top of her cleavage showing above the waterline. Her over-stretched tankini top fluttered around her in the turbulent water, and she grasped the front of it and pulled down, forcing any collected air from her abdomen and up into the tankini’s cups. The soft, blo-tex-lined Lycra cups swelled with the excess air, the domes expanding and rising higher out of the water, making it look like her breasts were inflating. Bigger and bigger they blew, beginning to obscure her face from his eyes as she tried to hide the growing smile on her face. Trish reached one hand up to her balloon breasts and ran her palm over each, eliciting a low-pitched squeak like two large balloons being rubbed together. “Do you like having an inflatable wife?” she asked, the lift from her suit tugging her slightly upward in the water.

“Wow, do I ever!” he stammered, sounding like an over-caffeinated high schooler on prom night. This was the biggest he had ever seen her become.

“Then come over here and play with my balloons,” she commanded coyly. Jack splashed across the tub, pushing his body between his wife’s legs, and placing his face into her burgeoning cleavage. Trisha felt the size of his covered passion press against her own aroused zone, and she wished that they both climbed in without anything clothing down there. She reveled at the feeling he elicited as Jack kissed the insides of her breasts and squeezed her nipples through the inflated part of his swimsuit, and raked her fingernails lustfully across his back, causing him to moan and growl with rapture.

That was when he felt the change begin.

At first, it felt like she was pressing her breasts together, trying to pinch his face between them and almost suffocating him. Jack pulled his face back, sucking in a surprised breath. Her breasts had grown so much that the straps of the tankini were beginning to dig into her shoulders, and leaving a line of indentation across her expanding flesh. Trish sat with her eyes closed, waiting for him to continue his fondling and kissing, unaware yet as to what was happening.

“Ah, Trish,” Jack stammered, “Your tits are blowing up.”

“I’ve been waiting all day to hear you say that,” she rambled excitedly, still not opening her eyes. “This suit is sooo tight; it’s going to really get stretched out.”

Jack edged forward and pressed his palms to the cups of her suit, and felt the pressure increasingly pushing back at him. “No, I mean it. Your boobs are blowing up like balloons!”

Trish opened her eyes and saw that her breast flesh was pushing upward and outward, almost touching her chin. And as she watched, they were getting bigger. “What the hell?” she questioned. This is not the way it was supposed to happen, she thought, confused.

Jack watched, stunned, as tit-flesh began to spill out the sides of the cups. The suit’s straps were digging into her painfully, so she pulled them off her shoulders just in time for her burgeoning mammaries to pop out of the overburdened tankini top.  What have I done? he thought.

The hot water bubbled and fizzed around the growing domes of flesh. Bigger and bigger they became, and she placed her hands on her nipples and pushed back into herself, trying to stop the growth. But all it did was bulge more expanding tits-flesh into her face. And they weren’t stopping, now the size of basketballs and still gaining in diameter and length. “Come on, I always wanted to be bigger, but not this huge!” she exclaimed, a note of anxiety to her voice. “How do I stop this?”

“I so sorry,” he said apologetically. “This is all my fault.”

“Your fault?” she asked, her face slowly disappearing behind her rising mounds. “I did this to myself.”

“What do you mean?” he questioned, slowing moving toward him as they blew bigger.

“I found a drug online called B.E.-lium. ‘B.E. for breast enhancement. I have been taking the pills for the past month, and nothing has changed…until now,” she explained, trying to wrap her arms around her growing boobs and finding she could no longer reach her nipples. “Why would you say this was your fault?”

“Because I found a breast enhancement powder online,” he said with a smirk. “You are supposed to rub it onto your breasts and then activate it with spraying yourself with water. I sprinkled some into your bra and into your tankini top this morning. It activated when we climbed into the hot tub.”

Despite their predicament, they laughed, appreciating the humor of the situation. Neither knew what kind of drug interaction was happening inside her, or how long it would last. “You wanted them big, you got BIG!” she chuffed, squeezing her inflating tits and making them bulge forward at him. Though she sat four feet away, her nipples were almost toughing him by then, and he reached out and gave each a playful tweak. “Hey,” she yelped, “they are a little sensitive right now.”

“There’s nothing little about them,” Jack responded, pinching the ends again. “You could put an eye out with those things.” He hesitated. “And I think you might have another problem.”

“What’s that?” Trish asked, her face now completely hidden behind her still-growing pontoons.

“Well,” he stammered, “they must not be heavy, since they aren’t sinking in the water. Normally breasts this size are too heavy to float on top of the water.”

“I can’t see a thing behind all this,” Trish said. All he could see was her hands waggling above two giant flesh-toned orbs. “Did you say they are floating, like balloons on the water’s surface? They truly don’t feel heavy, just…stretched.”

Her boob-balloons were now swelling into his face. “Can you stand?” he asked, pushing her breasts to either side as they grew past both sides of his head. Now all he could see was a cleavage canyon.

“I think so,” she said with a giggle.  “We are kinda running out of room in this tub, aren’t we?”

Jack heard her splash a bit as she tried to stand while maneuvering her massive blimps. Water dripped from her swimsuit as she rose, her breasts dipping slightly while still in contact with the water. “Wow, I really became my own floatation device,” Trish joked, placing her hands underneath her weather-balloon-sized breasts and lifting. That, she immediately found out, was the wrong thing to do. Because as soon as her breasts were no longer in contact with the surface of the pool, they began to rise higher…and higher…until they towered above her head with her nipples pointing resolutely upward into the evening sky.

“Whoops! Houston, we have a new problem,” she exclaimed. She arched backward, her breasts aiming straight up, and tried to grab onto the smooth edge of the tub and found nothing to latch a finger to. Jack watched, momentarily stunned, until he saw his wife’s legs begin to lift out of the water. She wasn’t trying to climb out, he realized, she was floating upward. “Grab me, you idiot!” she screamed. “I’m floating away!”

Jack grabbed both of her feet as they exited the pool. “I’ve got you!” he yelled, grasping her ankles and preventing her from going any higher. He looked up at the image of his floating wife from below, seeing only her smooth legs, dark blue bikini bottom, and two towering tits with arms to either side, flailing in the air. “You aren’t going anywhere.”

Her cleavage was pressing into her face, and she had to turn her head sideways in order to breathe. Jack pulled down on her ankles, but the upward tug from her boobs wouldn’t let him pull her down any further. “Are you alright?”

Trish started laughing. “That’s the craziest question you could ask me right now,” she said between guffaws. “I think my blowing up has stopped, for now, so we might want to find a way to get me secured to something before I fly away.”

Jack carefully climbed out of the tub while holding tightly to her legs. His weight easily held her down, but she still had enough buoyancy to not be able to stay grounded without a counterweight. He floated her under the covered part of the patio, away from the tub, the sloped cover preventing her from flying higher. “I’ll be right back,” he let go of her ankles, and she slowly ascended, her nipples scrapping slightly across the textured awning. He stepped into his garage and retrieved a length of rope, tying it then to one dangling ankle and securing the other end to a heavy wooden patio bench.

 When he finished the knot, Trish was left still floating about a yard off the ground.  Jack turned to admire his handiwork. Her arms hung at her sides, and the look on her face was a mix of frustration and amusement. “You just had to call them ‘blimps’, didn’t you?” he said mockingly. “You just had to say that you were ‘inflatable’!”

She smiled again. “”You always wanted them bigger,” she teased, swaying slightly in a warm evening breeze. “I’ll admit I wanted them bigger too, just not like this.”

He stepped up to her, wrapping his hands around her waist and pulling her down to his level, until her feel were again touching the ground. “Any idea how long this will last?” he asked, kissing her gently. “I think you will have to deflate a little before I can even fit you through the door in order to get you inside.”

“I have no idea,” she answered with a giggle. “Whatever you gave me must have reacted with the B.E.-lium that I took, causing this to happen.”

“B.E.-lium? As in.… helium?”

“Yup,” she smirked. “I could be floating and huge like this all night or all week, for all we know. And this is not how I was planning on ending the day for your birthday.”

“What did you have in mind?” he ask, a mischievous twinkle in his eye.

Trish reached out, grabbed his chin and pulled it to her, planting a wet kiss to his lips. “I tell you what…reach down below me and pull my bikini bottom off. No one can see us. I have an itch that needs scratching, and that fat, long blimp in your shorts is just the right size to take care of it.”

He did as he was commanded, tugging the swimsuit bottom off her shapely ass and leaving it dangling off the ankle that was roped to the patio furniture. He slipped his swim trunks off, tossing them back toward the still-bubbling hot tub. Jack sat on the bench, completely nude, and pulled his floating wife over and down to him. “We have certainly never done it this way before,” he commented excitedly.

Trish settled into his lap, feeling his strong hands slowly pull her down onto his manhood. She placed her hands into her cleavage and pushed her inflated boobs to either side so that she could see his face. He let go slightly, and she floated up, only to be pulled down again; up, down, again and again in a slow stroking motion.

“Happy birthday, dear!” she whispered hungrily. “Be gentle, or your balloon will pop too soon.”

Jack smiled. “Not a chance, babe. I rubbed some of that powder on myself this morning. It should be kicking in right about…”

“Ooooh,” Trish cooed, feeling him swell even more inside her. “A blimp, indeed!”
