To get to the Pyramid complex in time, we had to get up early. I was sorry to wake up Kim on the weekend morning – she is a real sleeper, and hates alarm clocks – but well, you can’t both have your fourteenth birthday pie and eat it, right? To my surprise, she opened her eyes and jumped out of bed as soon as I touched her shoulder.

“Today, Dad? Will it be today?” she asked excitedly and a bit nervously.

“Yes, honey, we’ll go to the Pyramid today,” I nodded. “Are you ready for your birthday present? Did you remember the training I gave you?” I couldn’t help but smile – no matter the number of times you repeat it, the feeling of her tight, warm flesh around your hard dick is something you can never get accustomed to. Kim’s real birthday was four times ago, so we had plenty of time to train before her weekend party.

“Don’t worry, Dad, I did!” Kim chirped.

I turned back and looked around our daughter’s room. The walls were filled with cute drawings of cartoon ponies and bunnies, already getting replaced with the rock star and porn star posters. There was a big dollhouse in a corner – Kim and her friends loved to play with it for hours, but soon it’ll be a new set of toys for my girl. And a pair of shiny metal handcuffs with pink fluffy cuffs on the desk, my early birthday present for my little angel. The present I used to start teaching Kim the art of pleasing a man. She’s been good.

“You will also have a surprise, honey,” I said. “Many guests are waiting for you today.”

When we entered the kitchen, Diana was standing naked by the window, finishing tying her hair into a tight bun. She smiled at us, hugged Kim, and kissed her.

“Happy birthday again, honey!” she said. “Let’s get a quick breakfast, and we’ll go.”

“Breakfast?” Kim asked, looking skeptically at her portion, which consisted just of a large cup of thick yogurt and a couple of scrambled eggs, the same as her mother’s. Mine, on the contrary, was a steak and egg wrap.

“Yes, dear.” Diana sat down and took her cup. “We need our stomach and rectum light and clean for today. You don’t want to vomit your breakfast under pressure, do you? And it’s much easier to get you an enema before we go this way.”

Kim shivered. She obviously didn’t enjoy enemas, but Diana always said it’s necessary for the good girl when there’s some hard sex planned. We used an enema at Kim’s training sessions once – well, at least twice; it was too tempting to fuck her little virgin asshole, clean and tight – and the little girl did not like it. Diana took a special pride in her ass, and always carefully cleaned herself before any major session. She was sure Kim must learn that too.

“And why does Dad have that much for breakfast?” she asked curiously.

“It’s because I have a different role,” I explained, chopping my steak. “To fuck for several hours straight, and to give many rich cumshots, men need a lot of energy and protein reserves. I’ll also drink the cum booster in the Gallery. Actually, all men will. Especially your guests.”

My little daughter’s cheeks reddened at the word “guests”. “How many guests, Dad?” she asked quietly, looking away.

“You’ll see, dear,” I smiled.

On our way to the Pyramid, Kim could not contain her excitement. She was fidgeting in the back seat and looking out the windows.

“Is it long yet? When will we be there?” she kept asking.

I admired her in the rearview mirror. Diana combed our daughter’s hair into the same tight bun, so it wouldn’t get in the way, and applied distinctive strokes of her new bright waterproof makeup, and dressed her in her new birthday dress. It was a short one, made of delicate transparent white cotton, with lots of lace and small frills, and most importantly – with a deep cleavage. It left her chest mostly naked and almost didn’t conceal her budding A-size breasts with their tiny pink nipples. Also, it wasn’t covering any other area below the waist, other than a little lacy skirt that barely reached her thighs. When she shifted in the car seat, I could catch glimpses of her cleanly shaved little pussy.

Diana wore about the same outfit – just her breasts kept her dress top tight.

“Not long, honey! We are almost there,” she smiled. “First, we’ll spend three hours in the Gallery, then we’ll have some proper dinner in the restaurant, then we’ll see. Probably we’ll watch some movie, and buy you more presents in the mall. This is your day, dear!”

When the giant glass pyramid of the entertainment complex appeared on the horizon, I switched the radio and prepared to find the parking lot closer to the main entrance. This early, on a Saturday, it was still not full, but the flow of families, couples, and groups of single men and women already streamed inside through the large glass doors. In an hour, the complex will become crowded and alive, and the Gallery will be no exception. We were wise to book two seats in advance, but we had to hurry up to claim our booking.

And there were also some curious eyes on us. Our small family, the proud father of the birthday girl and the mother accompanying her, was definitely the eye-catcher. The short, revealing dresses and the excitement in our daughter’s eyes made it obvious: we came here for a reason.

The Gallery’s receptionist nodded to us from behind her desk when we approached. She was a pretty high school girl, wearing only her uniform – a leather collar with her name embossed, and jewelry, which emphasized that the receptionist was also free for the guests. “Booking?” she asked with a slight, trained smile.

“Yes, two places for my wife Diana and my daughter Kim,” I answered, placing my wallet on the counter. “Reserved under the name Millers.”

“Just a moment.” She tapped into the computer and glanced at Kim. “First day at the Gallery?”

Kim blushed and looked down. “Y-yes, ma’am.”

The receptionist’s smile widened with a sly glint. She looked the child up and down, clearly appreciating the fresh, unspoiled meat. “Excellent choice. You are lucky; the place starts to fill, but you have two premium class seats for the whole 3 hours. Your seat numbers are 27 and 28.”She looked at us. “Do you need assistance in getting settled?”

“No, thank you,” I smiled at her. “Diana and I are your regulars; I’ll help my women. And, please, add one cum buster for me, 3-hour dose.”

She nodded, completed the transaction, put the paper ID bracelets on our wrists, and gave me the glass of greenish liquid that I finished in one gulp. Its taste was bitter and earthy, but its effect was worth it.

“Enjoy,” the receptionist told us. “If you’ll need anything, just ask the service personnel.”

The Gallery was, well, a gallery that circled the whole third floor of the Pyramid building. The air itself felt different here — heavier, warmer, carrying the mingled scents of expensive perfume, freshly brewed coffee, tobacco smoke, and the strong, musky undercurrent of sex, sperm and sweat. The panoramic windows gave a perfect view over the whole city, with its parks and the sea beaches.

There was a continuous ledge on the wall facing the windows, slightly below waist level, and there were plush leather seats on it, at regular intervals, with cuffs, straps, and some equipment. We walked slowly by, giving Kim a chance to get accustomed.

There were 150 seats in total; we knew it from the prospects, and on weekends they were usually all occupied. Even now, in the morning, about half of the seats were occupied already, and women kept coming, finding their seats, undressing, helping each other and being helped by the service girls to the places. The Gallery strongly stood for diversity, so there were all body types, skin colors, and ages, starting at fourteen and with no upper limit.

And all the women and girls were sitting naked in the same position, the teasing goods display to choose and use. The convenient soft seat under their butts, the shoulder straps under their arms carrying the main body weight, their legs raised, with the knees resting by their shoulders and their ankles strapped to the wall above their heads, their arms resting by the sides of the seat, with their wrists strapped to it.

They were free to wriggle in their suspension harnesses, move their heads, hands, and feet, twitch their hips, but nothing more. They were completely vulnerable and exposed – pussies and assholes on perfect display, their breasts accessible for groping, their faces at eye level. Those who were free had anal and vaginal plugs buzzing in their holes, keeping them aroused and ready.

And, of course, there were the fuckers – many men were already moving between the seats, some still sipping their coffee or finishing their sandwiches, some were unzipping their pants, and some were already pounding hard into the women, their rhythmic thrusts pushing gasps from the strapped bodies.

A business-looking woman was being anally fucked by a muscular, tattooed young fellow, her glasses askew and her head thrown back in passion. Next to her, a teenager had two men, one at her cunt, the other kissing her mouth deep, and the little slut was doing her best to please them both. The sounds formed a constant symphony of sexual congress, a mix of the slapping skin on skin, guttural groans, and muffled moans.

Some women were quite vocal and active. A slender black woman with large breasts screamed and shook in her harness, and her fucker barely had time to dodge as she squirted so profusely that the jet nearly reached the window across the aisle. Her man and the men nearby laughed and applauded, and he pushed into her again. An older, grey-haired woman calmly spoke with a newcomer who hadn’t decided which pussy to plunder yet, giving some friendly advice and recommendations.

The walls were covered with the instructions written in large letters. Diana and I knew them by heart, but Kim was reading them with her eyes wide open.

“ALWAYS keep the women on the warm-up when you aren’t using them.”

“Women aren’t just fuckmeat. Don’t forget to kiss, talk, and fondle.”

“When she begs you to stop, DO NOT STOP. That’s a part of the play.”

“Tickling and slapping are totally allowed.”

“Give them water to drink and keep their ass lubricated.”

“If you see the red light, then the woman has fainted. Finish fucking her, then, if she is not coming to, call the service personnel.”

“NO permanent injuries, NO hard violence.”

We finally reached our seats, 27 and 28. They were in a prime spot, near the large viewing window, with plenty of natural light. There was a twenty-plus mulatto strapped to seat 26, the green light above her head and zero on the electronic counter telling that she’s already warmed up for sex, but did not have any man yet for today. She winked at me.

“Would you like to fuck me, mister?...”

“Jameson.”

“Mister Jameson. I’m Naomi. I’m ready for five minutes already, and I’ll start screaming soon if nobody gives me a good inner rub!”

We laughed. I felt my cock getting hard.

“I will be glad! Just a few minutes, I’ll help my wife and daughter to their seats.”

Naomi smiled at Kim, who stared at her. “Hi, cutie! Is it your first day here?”

The girl nodded, looking at Naomi’s bare, glistening pussy, at the vaginal and anal plugs inside. “It ... It’s not scary?” Kim asked quietly, her eyes wide.

“Not at all!” Naomi reassured her. “It’s wonderful. You’ll see. The guys here know what they’re doing.” She glanced at her own light above, that just turned yellow. “Oh my, I’m so turned on already ... Please, mister Jameson, if you won’t use me now, my brain will melt from this toy in my ass and my cunt...”

Diana helped Kim out of her dress, and the girl stood there completely naked, her young pubescent body looking even more delicate and vulnerable against the backdrop of leather and chrome. Her little nipples stood erect in the cool, conditioned air.

“It’s alright, honey,” Diana said softly, seeing the trembling in her daughter’s knees. She helped Kim into the harness. “This will keep you comfortable and secure. Just relax into it.” She buckled the main strap under Kim’s arms, then gently guided her daughter’s feet up into the stirrups. “Lean back, that’s it. Right that.” She strapped Kim’s small feet to the wall above her head, then cuffed her wrists by the sides of the seat. “There are the pulse monitors in those cuffs. They will count your orgasms, and send the alarm if you faint from too much pleasure.”

“Faint?...” Kim whispered.

Diana kissed her forehead. “And it will show a green light, or yellow if your pussy gets too hot from the warm-up. Or, rarely, red. Let the guys do everything. Don’t fight them, and let your body enjoy.” She kissed her again. “Happy birthday, my love.”

I lubed the plugs that hung from the seat on the chain – the lube jars were everywhere here – and slowly pushed them into Kim’s holes. She bit her lip. She was already fourteen but still fresh and tight, and the plugs were of regular adult size, just like cocks that will be replacing them. I pushed slowly, carefully. Her tiny cunt was already used to it from my lessons, but her ass was still too tight. I had to press with more force than before to stretch her little sphincter and seat the plug inside. She made a small pained sound, but let it in.

Now she was just like the other women: helpless, exposed, with the plugs vibrating gently inside both of her tight holes. I pressed the button above her head, and her light turned to green, and the timer began the three-hour countdown. Her small hips gave a tiny, involuntary twitch. Her mouth was slightly open, and her breathing quickened.

Diana undressed quickly. Her curves, lush and familiar to me since college days, had the same effect on men as they always did. She strapped herself into the seat right next to our daughter, her experienced movements practiced and confident. I helped her to strap her feet and wrists, then I lubed her plugs too, and pushed them in. Diana sighed comfortably, the plugs disappearing easily into her well-trained orifices. She’d been coming here with me since we married fifteen years ago.

“Ready for a good fucking, love?” I whispered, leaning over her.

She grinned. “Always, Jamie. Just make sure our guests arrive soon. I want Kim’s birthday to become unforgettable!”

“Jamie ... Please...” Naomi almost moaned with lust.

“Coming, dear!”

Not wasting a second, I unzipped my pants and pulled the plug from Naomi’s vagina. A splash of clear liquid followed. She really was aroused to the threshold! I leaned to her, and our lips met, and her small but skillful tongue darted into my mouth, while I aligned my hard, cum-boosted throbbing shaft with her wet slit, and slid in without any resistance, burying my entire length in one smooth motion.
