"Are you joking? You want *me* to lead the prenatal exercise class?"

My boss shrugged nonchalantly. "AJ, Mei Hua gave birth last night. Her prenatal class starts in half an hour, and there's no one else to cover. Just help us out for a few weeks. Moving a few pregnant women around won't kill you!"

Seeing there was no room for negotiation, I reluctantly nodded and left his office to head to the instructors' locker room to change. *Sigh.* Leading a room full of heavy-bellied women through prenatal exercises!

A man demonstrating exercises in front of a group of pregnant women might look a bit ridiculous, but that wasn't the real issue. The real issue was that I loved pregnant women; they were my ultimate sexual fantasy. Just seeing a pregnant woman walking down the street would get me excited.

Now, standing in front of seven women in tight leotards for fifty minutes? I was definitely going to get hard. If they complained to the boss, I might lose my job. I took a cold shower to try and tuck my "little brother" away neatly in my trousers, wishing he were a bit smaller. But all I could do was sit in the classroom and wait for them to arrive.

My students began to trickle in one by one. Some wore sweaters and jeans, others wore tunics and oversized Bermuda shorts, and some wore T-shirts with tight leggings. God, I could even see the outlines of their bras and maternity panties! It was torture—all seven of them were quite attractive. I found myself wishing for at least one ugly face to help calm my excitement, but that seemed impossible. A wry smile tugged at my lips. *Talk about luck—a whole room full of beautiful pregnant women.*

First to arrive was Mei, whose T-shirt couldn't hide her full breasts, her tight leggings barely containing her eight-month belly. Jane was tall and slender, her short hair framing a face that was always smiling; her oversized jeans struggled to contain her nearly eight-month bump. June had dyed her hair a light brown, which complimented her baby face; her belly under her sundress looked to be about six or seven months along. Helen had been a flight attendant before her pregnancy, flying until she was four months along before taking leave once her abdomen began to protrude noticeably. The radiant, stunning woman told the class she planned to return to the skies in three months. Tiffany wore a pale pink shirt today, and through the fabric, I could see the lace of her bra hugging her rounded breasts. Mina, at thirty-five weeks, had a belly so large it stretched her maternity dress taut; she was constantly worried she might go into labor before the course ended. One after another, the women entered, making my head spin and a sweat break out.

Finally, there was Hazel. Her pure, innocent look and porcelain skin captivated me instantly. Her belly was the largest of the seven, looking even bigger than a woman in her final month (Mei later whispered to me that Hazel was actually only seven months along but carrying twins). Despite the massive bump, her figure remained incredibly curvaceous. Her sexy lips made me want to thrust my length straight into her mouth. She made my heart race; if I had to choose, Hazel was the one I wanted most. My "little brother" began to stir in my trousers, and the fabric started to feel tight.

When they entered the classroom and saw me, they looked surprised. I explained that their usual instructor, Mei Hua, had given birth last night and that I would be covering her final five weeks. They giggled and filed into the changing room to get into their workout gear.

Watching them emerge in small groups, my trousers grew tighter by the second. I knew I was in trouble. Mei's black leotard was somewhat sheer; she hadn't worn tight undershorts, so the distinct lines of a thong were visible at her waist and hips. Below the smooth curve of her abdomen were bare, luscious thighs that made it hard to stay composed.

My misfortune wasn't over. None of the seven were wearing bras under their leotards. Fourteen large, heavy breasts were laid out before me. Through the thin, tight fabric, I could clearly see the dark circles of their areolas and the distinct shapes of their nipples. Hazel was the most overwhelming. She was the kind of woman who could make a man climax right in his pants just by looking at her. She looked like a magazine cover model, but oh my god, her belly! Her massive bump, looking as though she were ten and a half months along, stretched her pink leotard as thin as sheer stockings; I could even see the faint silvery lines of her stretch marks. The low-cut neckline created a deep, inviting cleavage. Like Mei, her legs were bare, but she wasn't even wearing panties under her leotard. There were no lines at her hips, and as she moved, her full buttocks swayed provocatively. I struggled desperately to keep my erection in check. Hazel caught my gaze, blinked, and smiled, licking her luscious red lips. *Oh! She knows! She knows!*

"Well, let's begin today's session," I said, my voice dry and slightly trembling. The girls giggled, exchanging knowing glances. This class was going to be a nightmare. Every single one of them could clearly see my erection; I had to adjust myself to keep it from popping out of my waistband and introducing itself to everyone.

Pelvic exercises were the most difficult part. It felt as though I were gyrating my own manhood in front of them, and watching seven pregnant women sway their round, heavy bellies made the pressure between my legs even more intense. Mina began to roll her shoulders, her large breasts bouncing with the movement. The other girls followed suit, intentionally letting their breasts sway in waves. As I sat there, sweating profusely while watching the sea of bouncing breasts and swaying hips, they all laughed with pure delight.

June, with her baby face, dropped into a semi-squat, rocking her hips back and forth. The crotch of her peach-colored leotard looked damp. She asked teasingly, "Is the instructor feeling okay? Do you need some help?" The others erupted in laughter. Tiffany crouched down, her crotch moving provocatively toward me as she bit her finger, putting on an innocent expression. The tight fabric over her breasts was damp with sweat, making her dark areolas visible through the cloth. I felt like I was on the verge of an explosion.

"Uhm..." My breathing grew heavy as I tried to maintain a calm tone. "You... you all have very lovely figures..." I was nearly ready to burst right there in my pants, and I suspected all seven of them had noticed my predicament.

Mei stared directly at my crotch and giggled. "Well, instructor, we like your figure too..." "That's right, that's right!" Mina added enthusiastically.

"Alright," my voice wavered. "Now, let's do the kneeling pelvic lifts."

Have you ever seen seven full-breasted pregnant women kneeling on the floor, legs spread wide, leaning back? Their private areas were covered by nothing but a narrow strip of leotard fabric. Watching them support themselves, lifting and lowering their heavy, rounded bottoms, sent my blood rushing.

I wished I hadn't looked at Hazel's lower half. The crotch of her leotard was soaked through, becoming almost transparent. Beneath the tight fabric, the outline of her labia was prominent, leading up to a tiny bud of a clitoris and a patch of dark hair. Hazel looked at me, spreading her legs even wider. Beneath the wet fabric, her fleshy labia pulsed slightly. She smiled at me, her rounded buttocks swaying gently...

Hazel was the one who broke me. With a shudder, I released a hot burst of semen right into my tight trousers. The seven women saw the movement and cheered with high-pitched delight, clapping their hands. I felt like a complete idiot.

When the fifty minutes finally passed, I breathed a sigh of relief. "Alright, moms-to-be, class is over. See you next week."

Mina blinked and asked, "Do you dare to teach us again next week?"

I nodded. "Mei Hua will be on maternity leave for six weeks, so I'll be finishing the course with you."

The seven of them laughed happily. "Is that alright? If you'd prefer, I can ask the club to find a female instructor," I offered, secretly hoping they would say they wanted to keep me.

"No, no! We think this is wonderful!" Hazel said hurriedly. Her melodic voice made my "little brother" twitch again. I was absolutely reeling.

A week flew by, and it was time for the next class. As I stepped out of the locker room toward the classroom, my manhood was already hard as a rod. To hell with it; no one had complained to the boss yet, or else I would have been summoned to his office long ago.

As I reached for the door handle, I realized it was locked. "What the...?" I began to knock. After a moment, the door creaked open just a crack, and Mei peeked out. "Is that you, instructor?" Her large eyes blinked, and a mischievous smile played on her lips.

"It's me," I said, a bit miffed. "What are you girls up to? Locking the door during class is one thing, but locking the instructor out is a bit strange." She giggled. "We want to give you a surprise. Close your eyes and walk in."

I shrugged and closed my eyes, thinking of my boss's mantra: *'We must please the customer.'* Mei grabbed my hand and led me into the room. Behind us, the door clicked shut with a definitive *thud*.

"Okay, you can open your eyes now." As my eyes opened, the first thing I felt was a sudden, warm, slippery sensation in my trousers... The seven pregnant women, including my darling Hazel, were completely naked!

"The seven of us felt that wearing leotards... well... made it a bit difficult to move," Mei giggled. She winked at me. "You don't mind, do you, instructor?"

The seven heavy-bellied women formed a semi-circle before me. Mei stood tall, her eight-month belly looking slightly pale in the light. Tiffany and Helen were performing warm-up stretches; as they bent over to touch their toes, their heavy breasts dangled and swayed. Mina was practicing some belly dance moves, her hands behind her head, her body in a semi-squat as she provocatively swayed her hips. June stood there, playing with her own nipple with one hand. Jane was twisting her torso from side to side, her breasts looking as if they might spill out at any moment.

Hazel was kneeling on the floor, her arms straight, supporting herself. Her massive belly brushed against the carpet, her nipples only an inch from the floor. Seeing me watching her, she smiled, turned her back to me, and shifted her weight onto her feet.

It sounded simple, didn't it? Hazel was just shifting her weight. But it was the most breathtaking move I had ever seen. She stepped one leg back and out, then lifted her heel to show off the elegant line of her leg. At the same time, the fleshy crevice between her thighs and her dense, dark forest were laid bare to me behind her. The slight arch in her legs made her massive belly and breasts stand out even more. Hazel looked back over her shoulder, gave me a wink, and then extended her other leg back and out, still supporting herself with her hands. She was now crouching very low, her legs spread wide, unashamedly displaying the mysterious triangle of her crotch. Her dark labia were slightly parted like flower petals, her heavy buttocks split apart to reveal a pink, pulsing anus; her enormous belly still rested against the floor. Hazel turned her head again, throwing me one last smile as if asking, *"Do you like it?"* She slowly straightened her legs, lifting her hips in a defiant display before finally standing upright.

"Carrying a large belly often causes backaches," Hazel explained smoothly, looking back at me. I stood there, dazed, staring at this naked woman. She was the most beautiful, most erotic pregnant woman I had ever seen.

Her breasts and belly were unbelievably large. Her prominent mons pubis was covered in a tuft of dark hair. My eyes widened, and I stared shamelessly at her most private parts. When our eyes met, she smiled, and a jolt of electricity shot through my entire body.

"Are you done staring? Isn't it time for class, instructor?" Mina called out loudly.

Tiffany added, "Wait! We want you to be just like us. No clothes! Strip naked!" She was as excited as a child, tossing her dark hair back and licking her lips suggestively.

"Wait! Hold on!" I took a step back.

"Tiffany is right," Helen said, her naked, pregnant body looking delicious. "It's not fair if you're the only one clothed. It makes us feel like we're just cheap women who strip for anyone."

The other girls lowered their heads, looking coyly as they tried to cover themselves with their hands—as if two hands could hide their entire bodies. Hazel's hands couldn't even cover her breasts. Helen stepped forward and stripped my T-shirt off.

"Not bad!" she exclaimed. The others laughed as they inspected my muscles. I even struck a pose to show off a bicep. Jane ran up and yanked my tight trousers down, leaving my hard cock standing straight out in front of me.

"Wow!" "Hehe..." "It's so hard!" they whispered in awe. Jane reached out and stroked my glans with her finger, even bringing it to her mouth to lick it. "Wow! Your baby is huge!"

The other six swarmed around me. For the next few minutes, I just stood there, my trousers bunched at my ankles, as fourteen hands caressed and played with my manhood and my balls. Don't ask me how the hell I managed not to finish—having so many heavy, milk-filled breasts rubbing against your body, and so many large, pregnant bellies pressing against your buttocks, with every hand trying to squeeze the life out of your cock...

Mei barked, "Let's begin!" Though she was the smallest of the seven, she seemed to be the leader of this little group. The girls took their usual positions. I scrambled to pull off my socks and shoes.

"Are you all really going to do the whole class naked?" I asked, still a bit skeptical. They all nodded.

Helen shot back, "We pay good money to be here to exercise!"

"Alright, then let's get started!"

Those harlots actually went through the entire fifty-minute routine. It was pure torture. Watching those heavy-bellied women puff out their chests, twist their waists, and sway their hips—their naked bodies glistening with fragrant sweat. My cock was hard as an iron bar, and their eyes were glued to it, blowing kisses and licking their lips...

You cannot imagine the exquisite agony of facing seven naked pregnant women, watching their seductive movements, where every single pose was designed to trigger your lust. Watching those beautiful, heavy-bellied women sway their milk-heavy breasts and their massive bellies, watching their rounded, white buttocks part to reveal their glistening, sweaty vulvas... my glans was engorged, leaking clear pre-cum before I even realized it. The sight of me only made them more excited, causing them to work even harder to tease me with their bodies.

Then came the time for the kneeling pelvic lifts. The seven naked, pregnant women lined up, lying on their backs on the floor, knees bent, legs spread wide in a "fuck me" position, all of them swaying their anuses in unison...

A groan escaped my lips as my penis twitched. Hazel's secret cleft was right in front of me, her fleshy petals a deep, engorged red, framed by dark pubic hair, her slit pulsing with every sway of her hips...

Mina cried out, "Me first! Me first! I'm first!" My eyes shifted to her; her hands were busy fondling her hairy mound, her breathing rapid and shallow. Her flushed labia were slick and shining with arousal.

Mei called to me, "Hurry up! We already drew straws, Mina really is first!" Her voice was muffled because she was busy sucking on her marble-like nipple, while her hands worked her wet, slippery crotch.

"Oh... please..." Mina's thumb circled her clitoris vigorously, while her other hand pulled her deep red petals wide.

"I... I don't know..." I hesitated.

"Instructor, our husbands don't understand our needs. All seven of us haven't touched a man in ages!" Tiffany's soft voice was strained with rising heat. As she spoke, her hands were busy between her legs. "We all want it! Every single one of us!"

I knelt before Mina, gripping my rigid cock and rubbing the glans against her slippery labia. Mina groaned loudly, her body twisting as her hands pulled her vulva wide, begging me, "Save me! Save me!" The other six lay on the floor, masturbating while watching us.

My cock slid easily into her nectar-drenched vagina. Her body was scorching, and her insides were incredibly slick. I began to thrust slowly and deeply, pulling all the way out before plunging back in. Since a rapid pace might be too much for her thirty-six-week belly, I kept it gentle, a rhythmic, deep pounding. Mina's hands remained busy, pulling her lips apart to guide my shaft in and out. Her massive breasts swayed wildly between her arms.

With just one heavy thrust, Mina's entire body convulsed violently. Within a few more strokes, she came, her features contorting as she gasped for air as if she might die.

"My turn! My turn!" Before Mina's tremors had even subsided, Helen shouted excitedly. She asked, "Can you keep going?"

"Why don't you find out?" I teased, moving between her wide-spread thighs.

I buried my thick shaft between her lush, hairy thighs. As soon as the meat pushed into her, Helen shuddered, letting out a series of whimpering moans as she enjoyed the sensation of the glans hitting her cervix.

"Fuck me hard! Fuck me hard!" she began to pant heavily, her hands gripping her knees and pulling her torso upward. When she climaxed, her entire body went rigid, her ankles nearly touching her cheeks.

"Come on, fuck me! Hurry!" June began to scream.

As I pressed my iron-hard glans against her tiny, bud-like clitoris, June's baby face scrunched up, her eyes squeezed shut, and her teeth bit hard into her lower lip. I teased her for a long time before entering; I wanted this doll-like, beautiful woman to beg for it.

Driven by lust, June held her breath for a long time before finally breaking. She began to moan in a sobbing, desperate voice, "Oh, big brother, please put that thick meat inside me! Fuck me! Fuck me to death! My little pussy is going to explode! Use that big cock to fill my slutty hole! I can't take it! I'm dying! Save me! Save me! Fuck me to death!"

I pounded into her hard. Since she was only six months along, her belly wasn't too massive, so I dared to drive deep and fast. June's screams were high and piercing; the relentless pounding inside her made her throw her head back and shriek. The others scrambled to cover her mouth so the whole club wouldn't hear.

As I was still draped over June, I heard Jane's hungry moans. While Helen had been climaxing at my feet, Jane had already been rubbing her breasts and her clitoris until she was a mess on the floor. Now, she was calling for me.

Like a firefighter rushing to a blaze, I scrambled to her, kneeling between her parted legs. She immediately grabbed my cock and guided it toward her fiery slit.

With every thrust, Jane let out a cry. She only cried out seven times, but on the eighth deep plunge, her eyes flew wide, her mouth hung open, and her face flushed crimson as her lower body convulsed uncontrollably. It took three minutes for her to relax and catch her breath, finally allowing me to withdraw my rock-hard shaft.

Next was Mei. Despite her small frame, her eight-month belly was larger than the others. I was worried my size might be uncomfortable for her.

She was on all fours, her hips arched high in a begging position that was impossible to resist. Her slit was flooded with clear, slippery nectar. Once inside, she gripped me tightly. After just a few thrusts, Mei climaxed; she groaned, her whole body vibrating like a tuning fork, as she squeezed a spray of white fluid from her swollen petals. Her moans vibrated through her entire frame.

By now, I had been inside five pregnant women. In half an hour, I had brought five hungry, sexy women to multiple orgasms, their soaking vulvas gripping my cock. Yet, I remained hard and unspent, waiting for Hazel. I suspected they knew how much Hazel turned me on and had intentionally saved her for last.

Tiffany was the penultimate one, and she was a total slut. As my cock worked inside her, the effort was starting to show; sweat began to bead on my forehead. Fortunately, the feeling didn't last long—with a sudden, sharp gasp, Tiffany's walls clamped around me in a series of spasms, and she emptied herself all over me.

As Tiffany struggled to crawl away, I looked up to see Hazel standing there. Her massive, ten-month-sized belly loomed over my face. She shook her head and whispered five words: "Not in here!"

I shrugged, feeling a pang of disappointment. "Fine. Then forget it!" I thought she was rejecting me. I checked my watch with feigned nonchalance. "I suppose today's class is..."

"Instructor, it's not that!" Hazel's voice trembled with nerves. Mei stepped in. "Follow me!"

I followed the seven sweaty women into the women's changing room at the back of the classroom. My "little brother" was still as hard as an iron bar, coated in the love juices of the six women before her. It wasn't over yet—they wanted to shower with me!

"It's a bit difficult to shower with such big bellies," Mei laughed as she turned on the taps. "Do you want to join us?"

For the next half hour, the seven of them covered me in foam, and I lathered them all up in return. I don't think I've ever been cleaner. My hands roamed over every pair of massive, soapy breasts, while the girls competed to touch my iron rod, their large, slippery bellies pressing against me. The steam-filled room was filled with the silvery ring of their laughter.

Finally, they had me lie down on the warm, damp floor. From this angle, their breasts and bellies looked even more gargantuan. Suddenly, Hazel straddled me. My "little brother," which had softened slightly during the shower, instantly surged back to life.

She spread her legs on either side of my body, attempting to squat. Her skin was smooth and glowing, her flushed petals, covered in sparse hair, were slightly parted. The others supported her hands and torso, helping her lower herself slowly. As Hazel moved closer, her vulva opened wider; her swollen, engorged petals were slick with love juice.

Hazel rubbed her warm, wet labia against the tip of my glans. She looked down at me, breathing heavily. "Do you want me?"

"Oh! Yeah! Baby! Give it to me!"

"Do you want me?" she asked again, slowly grinding her hips. Her slippery petals felt incredible against my tip. She was teasing me, just as I had teased June.

I knew Hazel wanted to hear me beg. "Hazel, baby, fuck me! Fuck me! Use that soaking wet slit to fuck me! Use that hairy pussy to kill me... God, I need you so much!"

Hazel sat down hard, making me groan. Her vagina was as hot as a furnace, squeezing and sucking my shaft with intense pressure. She smiled down at me as her hips began a slow, rhythmic grind. Her wet petals bumped against my lower abdomen with every movement.

She was so beautiful. I caressed her thighs, moving up to the magnificent curve of her abdomen, before finally grasping her massive breasts and squeezing her marble-like nipples. Hazel began to tremble, pressing her weight harder against me, her breathing quickening.

I determined to last longer than her. The other six gathered around, watching while reaching down to masturbate themselves. Looking up, all I could see was a landscape of massive breasts and enormous bellies...

We were both panting heavily, our muscles taut as we fought to hold back the inevitable. Hazel's beautiful features began to contort, her face flushing with the approaching climax as if she were in the throes of labor. Mei and Mina began to support her, helping her grind against me even more hungrily. Hazel's fingers dug deep into the muscles of their arms.

My hand slid from Hazel's chest and belly down to the thick tuft of hair between her legs, caressing her clitoris. As I kneaded her tiny bud, Hazel cried out, her sexy lips parting wide. A flood of nectar poured from her as she sat on my cock, the sound of her wetness making a squelching noise with every movement.

We hit the peak at the same time. She threw all her weight down in a final, desperate sit, just as I groaned and erupted deep inside her. My hands were still working her nipples and clitoris as we peaked. In that same moment, Hazel's entire body shuddered, her convulsing walls clamping tightly around my ejaculating penis for a long, delicious ten seconds.

Hazel collapsed onto me, her heavy belly resting against mine. The other six cheered, helping her lift her hips so she could lie down beside me. Twelve hands worked to wash Hazel and me clean. Finally, today's class was over.
