As Bill typed away at his computer, his mind wandered to bigger things. He looked around the vibrant office space, twisting his neck around to catch Mel in his peripheral vision. She was at her desk rotating between typing, printing and scanning.

Quietly, he pushed his chair away from his desk and climbed down onto the carpeted floor beneath him. With everything seeming lively enough that he could move around relatively unnoticed, he planned to go meet Hank.

Wanting to avoid being caught, Bill kept his head down as he quickly shuffled across the floor towards the exit. Again, causing Bill to believe it may not actually be coincidence, he accidentally bumped straight into the ass of Rosie.

The towering woman turned to face him as he fell down onto his ass and looked back at her, panicked. He hadn’t expected to run into Rosie, it seemed a little odd that he always seemed to. Although, he couldn’t give her all the blame - he had bumped into her after all. “Hey cutie! You gotta watch where you’re going, a girl might get the wrong idea!” she said, her lips curling from her cheeky grin. She furrowed her brow, “What are you doing anyway?”

Bill’s heart thumped powerfully in his chest as her mood changed from flirtatious to suspicious. He stuttered, “Err… Err… I need to go see Hank”.

“Hank? Why would you need Hank?” Rosie asked as she placed her hands onto her hips, looking down at the flustered man.

“He… He… is supposed to install updates to my workstation,” Bill reasoned, successfully finding something reasonable to excuse why he needed Hank.

“Hmmm…” Rosie responded as she thought about it. She explained, “Val caught Hank sneaking around where he shouldn’t have been…”

“Oh no, really? Well, where is he?” Bill asked, his voice showing faint signs of the fear and concern he was feeling after her words. Another one of his friends, and co-conspirator, had been wiped out. Was he next? Would it be wise to even try to rebel when the chance of failure was clearly so high?

Looking at her nails as she spoke, Rosie enlightened him, “She gave him to her younger sister, Brenda. She’s head of IT Security. And, oh boy, you should see her!” Bill just kept her gaze, not speaking and simply waiting to hear what else Rosie had to say. He wasn’t sure he wanted to know, a sister of Val couldn’t exactly be a young beauty.

“Oh man, she’s the same… stature, for lack of a better word, as Val. Maybe with an even bigger ass!” Rosie explained, causing Bill’s eyes to widen as his fears were confirmed.

“B-bigger?” Bill replied, his voice wispy and fearful. Was Hank doomed? No, surely not! It can’t be over this easily, his friends were relying on him now!

“Yeah. Bigger. Do you like bigger?” Rosie asked flirtatiously. “I’m not Val or Brenda, but I’m certainly bigger than you!” she teased as she reached down and playfully pushed his shoulder, causing Bill to stumble back.

Bill scratched his head nervously, tearing himself away from her piercing gaze and looking deep into the carpet in front of him. “Do… Do you think you could take me to him?” Bill asked, hoping she’d allow him to brush over what she had just said.

“All I seem to be doing are things for you… When are you going to do something for me?” Rosie asked, her eyes bright with lust. She rolled her tongue across her lips to moisten them, tasting her lip balm as she did. Before Bill needed to think of a reply, Rosie continued, “But sure, I’ll take you. You owe me more than one!”

Rosie spun on her heel, her perky ass bouncing in Bill’s face as she did. She quickly began to make her way out of the office and into the labyrinth of hallways. Bill waddled behind her, trying his best to keep up with her long, slender legs.

After a short time following Rosie, Bill panting all the way as he struggled to keep up, they reached Brenda’s office. With the door closed, their first port of call was her admin, Juana. She seemed to be in her early 40s and Bill couldn’t help but marvel at her killer curves. His trance-like stare was cut short as her eyes met his, causing Bill to look up and hope she hadn’t seen him gawking. She smiled at him calmly with a warm, almost mothering smile.

“Hey Juana! I was just bringing this little guy to see Hank. Is he available?” Rosie asked simply.

Juana’s warm smile turned cold as she heard Rosie’s words. She spoke plainly, “Sorry, Brenda’s indisposed at the moment”.

Not wanting his opportunity to fade, Bill pleaded, “Please, it’s urgent! He was meant to update my computer” He looked deep into Juana’s eyes, hoping to tap into her empathy.

“Okay, we’ll have a look!” Juana replied, standing up from her desk and making the short walk to Brenda’s office door. Slowly, she opened it.

As the door crept open and Bill got a view inside, he was blown away. His perception of Brenda had been totally underestimated, she was a mountain of a woman. Much like her older sister, with her office door shut, she was found sitting in a giant armless chair in a skirt that was rolled up. Her monstrous ass flowed out over the sides of the chair as she wiggled and grinded her ass and vagina into it.

Muffled cries spewed out from beneath her whenever she lifted her ass even a slither off of the seat. Brenda yelled down as she heard them, “Hey! Shut up down there!” She ground her ass harder into the chair to reinforce her command and sat there still for a moment, enjoying the squirms and silence.

Looking up, Brenda spotted that her office door had opened and three people were looking in. “Juana! What’s the meaning of this? I thought I told you I didn’t want any interruptions?” she asked, clearly displeased that her session with what they all assumed to be Hank beneath her had been interrupted.

“Sorry m’am! Rosie and err…” Juana began to say as she realised she didn’t actually know the name of the small man beside her.

“Bill!” Bill chirped up, trying to hide his nerves.

“... and Bill here needed to see Hank. I believe he was meant to update his computer before… Well… His role change.” Juana explained, clearly choosing her words carefully.

As the two women spoke, Rosie crouched down beside Bill and whispered in his ear, “Do you hear those cries from beneath that enormous caboose of hers? I bet that’s Hank under there, getting all cosy with her coochie.”

Juana noticed Rosie whispering down to Bill and flared her an angry look, before turning her attention back to Brenda. Looking at Bill, Brenda spoke, “I didn’t see anything for - Bill is it? That’s your name? Come here”. She pointed at him and curled her finger towards herself to gesture that he should come to her.

Bill hesitantly made his way across the office, feeling vulnerable without Juana and Rosie separating him from this elephantine woman. He didn’t even know a bigger ass than Val’s was possible, but here it was. As he approached, the previous silence turned to faint cries as Hank’s screams for help struggled to escape very far past the layers of fat. Bill couldn’t help but stare at her obese, cellulite-ridden, quaking ass as it splayed out over the sides of her seat.

“Sorry Brenda, maybe I was supposed to download it…” he began, pausing while he thought of what else to add to this out of hand lie. “I just can’t afford to fall behind with Val” Bill continued, hoping to play on her sympathy.

“No, no you can’t.” Brenda agreed. She wiggled her ass as she began to lean forward, faint, muffled cries broke through as she began to lift herself off the chair. “If it’s for my sis - 1 minute, that’s all you get”, she said.

Bill paused and waited as Brenda seemed to have stopped with her ass only partially raised. As some time went by, Brenda finally got impatient, “Well? Get him!”

Bill gulped realising it was his responsibility to get Hank. Approaching slowly, he peered under her monstrous ass. He stared directly at her bare ass, unable to see Hank anywhere - such depths of her ass still remained between her clenched cheeks. “Erm, I can’t find him.” Hank explained to Brenda, not wanting to dig his hands into her huge, sweaty ass.

“Oh sorry, here!” Brenda replied as she reached behind and gripped at her huge cheeks. Bill stared intently as her cheeks parted before him, Hank’s cries becoming more pronounced as they did.

As her cheeks separated completely, a stiff, tied-up little man fell down onto the seat with a wet slap. He was naked aside from his bindings and a ball gag - stopping him from making much more than moans and whimpers. Despite having the same diminutive stature as before, Hank was, in a sense… bigger. Part of him at least. His penis looked like some sort of experiment gone wrong. It was monstrous. Hard as a rock, it stood roughly half the size of him. His abnormally disproportionate member and midsection were completely covered in Brenda’s cum, her pubic hairs sticking to his body as if her cum were glue. “What the? How?” Bill asked, too shocked to worry about speaking out of turn.

“Oh that thing? When Val discovered him snooping around where he shouldn’t have been, she offered him to me,” Brenda began to explain, sitting back down on top of Hank while she did. Bill’s eyes widened as a terrified scream broke through Hank’s ball gag, being silenced only once she had fully sat down. She continued, “I explained I really only enjoy men of a certain size. And apparently R&D has been experimenting with the tea. Let’s just say, I ain’t complaining.

Brenda raised her ass once more and pulled him out from beneath her for Bill. Standing Hank up on her desk, his legs shook as he was barely able to support his weight. Rosie caught a glimpse of him finally and rushed into the room “Oh my God! Look at that thing, it must be nine inches long!”

“Yeah well, I’m a big gal. Big gal’s need big men, at least where it counts. Isn’t that right Hank?” She asked, gripping his dick firmly in her hand and tugging at it. She looked back over to Bill as she slowly worked Hank’s permanently hard dick in her hand, “Ask him your question”.

Bill stuttered as he struggled to focus on talking to Hank as if he wasn’t being currently violated, “Ermm… Hank. Do-do you remember those up… updates you were supposed to install?”

“Mmmmuuuuuuuhhhhhhh,” Hank moaned incoherently, the ball gag still stopping him from being able to make any noise worth making.

“Wow Brenda, you sure did a number on him!” Rosie chuckled, Juana just looking on in pity.

Brenda ground her ass sensually into her chair as she looked over to Hank’s huge schlong longingly. She explained to Rosie, “Of course I did, I’m a tough woman to please!”

“Aren’t you afraid of him cumming in you though?” Rosie asked, curious.

“Ha! Bless your heart, sweetie. I turn fifty next month, that ship up and sailed a long time ago!” Brenda laughed, “Besides, that concoction means he keeps going for three or four times as long; with about a minute-long refractory period”.

Juana chimed in, “Erm, Brenda, I think Bill can’t understand Hank with the gag in his mouth.”

Brenda chuckled as she pried the gag out of Hank’s mouth with her meaty claws, her huge breasts hanging down directly in front of him. Val spoke, “Hank, Bill here says you were supposed to install some updates for him, but I don’t see anything on the docket. Care to enlighten us?”

Hank, in a state of delirium, stared off into space. He wheezed, “MMMMMaaaail”.

Bill, horrified to see his friend in such a way, frantically asked, “Mail? What mail? I never got any mail.”

Brenda cut in, “Sweetie I hate to break it to you, but I don’t think he’s all there - if you know what I mean. He’s been under me since about…” She looked at the clock for a moment, “Since about nine this morning.”

“Well could I come back later then?” Bill asked timidly.

“I’m not sure what good that would do you. Being my little fuck cushion’s about all he’s good for now. Besides, I didn’t see any critical updates for admins today, so you should be good. Now if you don’t mind…” Brenda trailed off as she reached for Hank from the table, “This is my mid-afternoon break.”

She roughly shoved the ball gag back into his mouth as she raised him up from the desk. Standing slightly from her armless chair, she placed him back on her seat beneath her enormous rump.

Reaching between her legs, she gripped his still rock hard penis with one hand and separated a cheek with the other - giving Bill an unholy sight of her obese ass and hairy, dripping cunt. Hank was still wheezing as she slowly began to sit down, guiding his huge dick into her cunt with an ugly moan. “Fuck me, you’ve got the perfect dick!” Brenda moaned out, wiggling her huge cheeks as she lowered herself completely onto the chair - a huge fart escaping out from beneath her. Hank suddenly screamed out, the gag and her fat muffling most of the sound.

Bouncing and grinding into her chair, Brenda said, “Juana, please see Rosie and Bill out.”

Rosie grabbed Bill’s hand and spoke, “Don’t worry, I can see him back to his desk!” She turned to leave and immediately made her way out of the room with Bill struggling to keep up in tow. As they left, and Juana shut the door behind them, the sound of Hank screaming while Brenda continued to bounce her enormous ass onto him filled the room until the door was finally shut. Poor Hank, Bill thought, this was his life now - a life of being continuously raped by a woman as much a monster as her older sister.
