While Amy was busy fucking Eight and sucking Twelve, the Third Doctor had been glancing out the window with intrigue. He watched the Sixth Doctor leave the house, cock still very much exposed, and run inside his TARDIS. He emerged a few seconds later with a girl in a tight, low-cut pink dress. She had her dark hair in a neatly-cut bob, and her dress seemed designed to squeeze her breasts together as much as possible. He spoke to her for a moment, and the Third Doctor watched her get down on her knees, level with the Sixth Doctor's swaying cock. Six seemed frustrated and pulled her back to her feet, then spun her around and pressed her front against his TARDIS doors. He pulled the short dress up around her ass and thrust himself into her, then barked something at her. She wrapped her legs behind his and he grabbed her breasts to hold her up, before walking her back towards the house. The Third Doctor chuckled to himself at the sight.
Just as the Eighth Doctor was shooting his seed deep inside Amy's velvety pussy, the bedroom door crashed open and in came the Sixth Doctor, bouncing Peri on his cock. She looked somewhat frightened by all the strange naked men around her, many of them well into their sixties. But the Doctor had promised her that winning lottery ticket after he was done with her, and she wasn't about to give that up now.
"Remember these, boys?" the Sixth Doctor remarked, and tossed her by her tits up in the air, then let the bloated pincushions fall back into his hands so he could juggle her again. He did this several times, and it helped that he kept his cock nestled deep inside her pussy, so she had less chance of falling off. She squealed and yelped as she was alternately groped and tossed in the air. The War Doctor came close to inspect, and pulled Peri's elastic pink v-neck down below her breasts. They popped out one at a time, all round and marshmallowy, and he spent a full minute just watching them bounce before leaning in with his bristly beard to nibble gently on her nipples.
The Ninth Doctor had moved up to Amy's mouth, having shed his leather jacket and now wearing only a t-shirt, and without a second thought Amy took his cock in her mouth. "Yeah, that's right," he muttered. "Suck it, darlin', suck it."
Amy briefly took her mouth off of him with a puzzled look on her face. "I don't get it," she said. "You're an alien, right? So why do you sound like you're from the north of England?"
"Lots of planets 'ave a north!" The familiar line had come, not from the Ninth Doctor, but from a female voice in the doorway. A blonde woman stood there, wearing a long grey coat and suspenders, rocking platform boots to make her look taller. The Thirteenth Doctor had arrived.
"Sorry I'm late," she said. "I didn't do the whole war thing so I didn't know exactly when to show up, but-"
"Who are you?" the First Doctor huffed.
She was about to respond, when the Third Doctor interjected, "She's mine!"
He'd been waiting for a chance to get inside this Peri girl's ass, but when he saw the pretty, young blonde come in, he figured one companion was as good as another. Besides, she reminded him of Jo Grant. He pulled her close before unclipping her suspenders- "Strange dress sense," he muttered with his distinguishing lisp- and shucking down her trousers. Before she could get a word in edgewise he'd slipped her ass onto his cock, plunging up into her tight hole. The Thirteenth Doctor had only been able to gasp as she felt him invade her, then she moaned to the skies when he started bouncing her up and down. But she realized suddenly that it felt really, really good. As a woman, it just felt right to be filled during sex. She'd assumed she was just going to finger Amy a bit, or something like that- truth be told she hadn't thought that far ahead. But she barely even remembered being the Third Doctor at this point, and was experiencing too much pleasure to care. She pulled off her coat and t-shirt before she fell to the ground and laid her arms out flat on the rug. Her modest tits dragged lightly on the carpet as her raised ass was pummeled from behind, sending shockwaves of delight through her slight frame.
When she started panting, he knew he'd done right, and knew that she'd be wet enough now to fuck properly. The Thirteenth Doctor felt him slip out of her asshole, and just as quickly sink up into her pussy. This was the first time she'd been fucked in the pussy in her entire multi-millennial life- she couldn't remember ever being fucked in the ass either, but she'd lived an awfully long time; it was bound to have happened at some point- but this feeling was incredibly new and unique. So many nerve endings! So much pleasure unfurling from so many different places! She moaned contentedly as the Third Doctor rutted her soundly.
The Fourth Doctor wasn't about to pass Amy up on her offer, and bent over her with cock in hand as she sucked off Nine. She presented her round ass to Four like a trophy, spreading her cheeks to make sure her tight pucker was visible. By the looks of things, she was not a frequent ass-fucker.
"Ooh, Amy," the Fourth Doctor declared. "I haven't seen an arse that neglected since Jamie." A round of laughter from the first few Doctors. "Ah, poor lad. I hope he found a good man someday." The Sixth Doctor looked up nervously, remembering Jamie's rather untimely death, then thought better of mentioning it and continued to plow Peri while he watched the Ninth Doctor cover Amy's cute face in long strands of cum.
Amy bowed her head under her long, red hair and inhaled deeply as she felt Scarf Boy press at her asshole. He parted her inner walls in the most breathtaking way, and she gave a couple of high-pitched yelps as she closed her eyes in ecstasy. Then the Fourth Doctor went farther than two inches and buried himself in her backside, making her cry out a string of "Oh! Oh! Oh yes! Yesyesyes yeeessss!" Amy Pond's ass was full of cock, and the world was right again.
"Yeah, take it, Amy!" the Thirteenth Doctor cheered. "Right on, girl, right- OH!"
The Third Doctor had returned to Thirteen's ass, seeing the joy it was causing Amy. The mysterious woman's ass looked so good parted around his thick cock, and her pert cheeks wobbled every time he slapped into them. She started panting and moaning again, and raised up her torso with her arms to show off her breasts as her waist was nailed to the floor. She immediately felt, and more importantly smelled, the Second Doctor's cock and balls in her face. She was a bit irritated, but mostly surprised how quickly the pair of Doctors had taken to her. She gave him a smile with put-on sweetness and said, "Hi, I'm the..." before her open mouth was stuffed with cock. The Second Doctor held her head in place, weaving his fingers into her platinum blonde hair as she reluctantly sucked him.
Looking around the room, the Sixth Doctor had noticed a sudden increase in assfucking take place. He'd been waiting for the right moment to introduce Peri to that side of things, and couldn't think of a better time than the present. Continuing to bounce her up and down, he held up her bum and seamlessly transitioned from a deep thrust in her pussy, to bottoming out in her fresh, tender asshole. The blood-curdling shriek Peri gave made everyone stop in their tracks and watch her take it. The sound was unmistakably one of an anal virgin, and of a sudden and unprepared filling. But her ass belonged to the Doctor and he used her as he pleased. Soon she was moaning as hard as she'd been doing when he was in her pussy.
"Do you think Rory would like to fuck my arse?" Amy asked the room abruptly, over the sounds of three assholes getting pounded. The Eleventh Doctor looked at her with shock.
"You mean you've never let Rory but you're letting... bloody Scarfie do it?"
"I dunno! It doesn't seem like Rory's thing. He's not very good at...you know..."
"Being a man," Twelve muttered to Eleven.
