It was a nice day on Nowhere Island, and so far, Dr. Eggman hasn't made an attack in a while so the group could relax. Or at least, one of them anyways. Inside the workshop, some moaning could be heard. A certain two tailed fox was wrapping his hand around an erection, pumping himself as he held onto his workbench for support.
"Aahh... ahh... ah!~ I-I'm so... hot...! Nnnh...!~" The fox boy moaned, biting his lower lip as he kept jerking himself off. He had completely forgotten that at certain times, he could go into heat. One of the curse of having some animal traits. Right now, he felt so hot and bothered that he took to a quick fap session.
Tails had been at this for what seemed like an hour now since the whole thing began, drops of pre began leaking out as the fox blushes. "I'm gonna cum...! Nngh... Aaaahh!~" He moans loudly and stains the floor and some of his gloved hand. He sank to his knees and breathed a deep sigh of relief, his body slowly cooling down from the afterglow.
The two tailed fox brought his hand to his mouth and licked off his own cum. Taking one finger in and out, sucking it almost like a lollipop. He swallows and sighs again. He would have to clean up the mess he made. He brought out a cloth and cleaned up the mess and put in the garbage.
"Maybe some fresh air would do me good. I've been cooped up in here for a while. Besides, I don't really feel like inventing right now." He says to himself, he decided to write a note explaining he needed a break and was going to relax some place. Last thing he needed was to make his team worried.
Once that was done, he went outside and headed into the village, getting a bit hungry from that session. Tails goes to Meh Burger, and it didn't look busy. There was Dave, as usual. Before the fox could even open his mouth, he gasps and feels that familiar heat again.
'Dammit! I thought I was over that! I can't be in heat again!?' He thought to himself in disbelief, Dave just stared at the fox with a mixture of confusion and slight concern, noticing the flushed cheeks on the fox boy's fur. "Uh... are you okay, sir?" He asked him, Tails tried to brush it off and smiled, althought it was forced, and Dave would know.
"O-o-oh! I-I'm fine Dave! Can I please get a... nngh! A... ahh... n-no..." But he couldn't do it, he held onto the counter and felt like he would collapse right then and there. It's when Dave finally notices what's going on and smirks, places his arms on the counter and chuckles. "Oh, I see... you're in heat foxy~"

Tails blushes even more and whines. "O-okay! I'm in heat! I thought I would be fine and-aahh... O-oh God... please... help me..." Dave suddenly got an idea, he wasn't particularly busy anyways. "I have just the thing that could help you, Tails." The horny fox would take anything right now and nodded quickly.
Before he knew it, he was at the Lightning Bolt Society's Hideout. As the nutria led him towards their base, it was then that Dave just now notices how feminine Tails was. He has that slim, curvy figure, his feminine voice that hadn't hit puberty yet and that plump ass that looked rather soft to touch.
Dave had brought Tails to his friends, the Weasel Bandits and Wily Walrus. Of course, they were surprised to see him back, considering that he failed to be a villain and outright quit. "Why is he back here, Dave?! And what's wrong with him?" The walrus asked as Tails began to explain, "I-I'm... in heat...! My body's burning up and... I... *sniff* I need help..."
He honestly felt like crying, it feels so bad. "So I thought we could help our ex-member with his 'problem'~" Dave says and winks at his accomplices. They got the message and smiled. "Anyone's up for grabs. It doesn't matter who." The three weasels stepped forward and approached the suffering fox.
The red bandana one brought Tails' face to his and began kissing him. Tails eagerly kisses back and moans, the other two, the yellow and blue ones decided to have some fun with Tails' crotch. They got on their knees as one sucked and licked his balls, the other began licking the shaft.
The two tailed fox was moaning in bliss, never once thinking that this would happen to him in his life. Dave and Wily in the meantime got erect and watched the show, slowly jerking themselves off and waiting for their turn with the horny fox boy. "Pfhahh... his balls are so good...~" The yellow bandana weasel says, the blue one chuckles and licks the shaft.
"You should try his cock, it's so good~ Listen to his moans!" Tails' eyes were half lidded in pleasure, taking it all in, what was done to him and their comments on how he was acting. He didn't care. He needed this so badly. The weasel that kissed him pulled away for a moment and smiles.
"How about you work on our own shafts, mate?~" He says, the fox nodded. The weasels got into position as Tails got on his knees, he took one cock in each hand and opened his mouth to suck the other. The trio groaned in pleasure, watching as the two tailed fox was pleasing them. "Ooh, fuck...! Look at'em go! Heheh... he's such a cute slut!~"
Tails blushes and continued working their cocks and sucking one off, swirling his tongue. Practice with some of his secret sex toys paid off for once!  His namesake's swished back and forth as he pleases the weasels. His cock twitching and throbbing. He switched one weasel to the next in sucking their cocks off.
Dave had never seen the fox acting like this before, whether it was the heat doing the work or he was a natural slut deep down inside didn't matter. All the same, the sight was hot enough to almost make him cum right then and there. Almost. After a while, Tails started picking up the pace as the Weasel Bandits moan.
"Oh God, his mouth is so good! How is he this skilled?!" One moaned out and the other whines in pleasure. "Nngh...! F-fuck... I'mma 'bout to burst!~ He's too good!~" Tails smiles and continues stroking and sucking them off, feeling their throbbing cocks just begging to release their warm cum all over him.
Tails pulls away from the weasel he was sucking off and starts licking the head. "Mmmh... c'mon and cum all over me you naughty criminals!~ Paint this fox white!~" Tails says and giggles, that was enough for the bandits to blow their load, Tails opening his mouth and catching a few shots inside.
He could feel the warm cum staining his face, hair, goggles and chest. He swallowed the rest of their loads and sighs happily. The Weasel Bandits stepped back and groaned, their cocks flaccid for now as they watched the slutty fox enjoying his meal. "Holy shit... we should have done this in the first place! This guy's a natural!~"
The two tailed fox smiles, his cock twitching and he looks eager for some more. "I hope you have more for me, guys~ I'm still in heat, y'know." Dave approached the fox boy and made him lie down on his back, his legs spread apart as he looked at the nutria with lust. "I bet you've been wanting to fuck this fox booty, huh?~"
Dave chuckles and prods his erection at the fox's anus, earning him a small moan. "Don't you know it~ You want some dick to fuck your little ass?~" Dave teases, nudging and grinding at the entrance, making the poor two tailed genius pant and whimper. "Yes... yes, please!~ Please put it in! My asshole's so empty!"
"Alrighty then!~" Dave shoves his cock inside as both boys moan, the nutria could feel the tightness around his cock as Tails couldn't keep the smile off of his face. The male started moving himself inside of Tails' tight ass, hearing his feminine moans and panting. "Mmh... G-God damn... Tails...! It's like your ass is begging for dick!~"

Tails just let Dave take control and giggle, the Weasel Bandits regained their stamina and were full mast again, watching their member fucking the eager fox boy. "Oh God, I needed this so much...! More... please, more...!~ Really rape me!~" Tails pleaded, not caring how much of a shameless slut he sounded at the moment.
He felt a spank on his rear and squealed with a mixture of pain and pleasure, his ass cheek jiggling upon contact from Dave. He sped up his thrusts and kept spanking the boy, switching from asscheek to the other. "Like this, Tails?! Is this what you wanted you two tailed whore!?" Tails just moaned and squealed with pleasure, he nodded as his cock twitched.
"Yes!~ Please use me! My fox bussy is all yours to fuck and use!~ Please fuck me until I can't walk!~" Dave grabbed Tails' cock and quickly jerked him off, making the fox boy roll his eyes back and moan loudly. "How's this feel, you foxy faggot!?" Tails didn't even mind the derogatory name calling, in fact, it enhanced the experience for him.
"It feels sooooo good!~ Use my body! Please!~ Make my heat go away!~" The abuse on his ass, the pleasure of his cock, and the thrusting inside his asshole, it was all too much for the poor fox to handle. The Weasel Bandits and Wily Walrus watched, jerking off as they watched Tails degrade himself into a lowly slut.
"Get ready for my cum, Tails!~ Once you have it, you won't ever go back!~" Dave thrusts faster as Tails gritted his teeth, drooling as his cock began leaking pre. "Nnghh!~" The nutria gave one last push, cumming balls deep inside the two tailed fox and groans, filling the boy up and watching him blow his load, staining his chest.
Dave pulls out and added more cum into the fox's fur, watching as Tails collapsed onto the floor, panting and catching his breath from the intense session. His ass cheeks a bit red and showed Dave's handprints, his anus leaking his semen, and Tails had the most happiest expression on his cute face.
"Hahh... ahh... ahh... O-oh yeah... that felt so good...~ Thank you for filling me up...~" Tails said and moans. "Oh, it's not over yet. Right big guy?" Tails suddenly felt himself being lifted off the ground and in a full nelson position, with Dave and the weasel trio watching him, helpless to do anything, not that he would fight back anyways.
"It's my turn now, foxy!~ Get ready for a real cock fuckin' ya!~" Wily says and chuckles, Tails' gazes down at the erection and his eyes widened, regaining his sanity for a moment. "H-holy crap...! It's massive! That must be like... 14 inches! U-uh... I'm not sure it'll fit-" His words fell on deaf ears as the walrus shoved his massive length inside Tails, making him scream bloody murder.
He couldn't help but cum again, staining the floor as he groaned, his eyes going cross and tongue lolling out, used as a human sex toy. The other males laughed, seeing Wily thrust inside the fox, and the outline of his cock bulging from his stomach. Tails' cock flopping with every movement and leaking pre like a faucet as he groaned and moaned like a wild feral animal.
"Hahaha!~ Listen to this guy! He loves it!~ See? I made it fit after all!~" Wily gloated as the other boys laughed. "God damn, I've never seen the fox like this before!~ We should've fucked him as soon as we saw'em!" One of the weasel's piped up. "A-fucking-men to that!~" Replied the other and jerked themselves off.
"Hehehe... it's like Tails was just BEGGING to be fucked!~ Look at his stupid face!~" Dave mocked, all Tails could do was gurgle, moan and be used like the fucktoy he really was. His mind going all over the place. On one hand, he wanted this to end and just go home. But the other thought was clearly winning. Stay, and he could have this all the time~
"Mmmh... I'm gonna make your ass loose Tails!~ You're just a regular femboy slut!~" The fox just blushes and gave a dumb smile. "Hghgh... gbhfh... aahahbgh..." Whatever he was trying to say, was reduced to gibberish and moans. Wily went faster and harder, making the fox go wide eyed and groan loudly, drooling and his cock firing a few loads from time to time, staining the floor and making a puddle.
"OOogh!~ Hhghg!~ Aaaagh!~ Hhah!~ Yesh!~ Moa!~" He slurred his words, as the group watched the outline of Wily's cock extending the poor fox's stomach. "Oh yeah... you're gonna be our Society's cocksleeve! No way we're passing this up, right boys?!" Dave and the Weasel Bandits cheered as pre began leaking from the walrus' shaft.
"TAKE MY CUM, YOU FUCKING FAGGOT!!!~" Tails gave a loud scream as he was filled up, his stomach expanding and bulging, his eyes rolling back and felt the warm cum inside his stomach, mixing with Dave's. He was lifted off and plopped to the ground, Tails lying on his back and whimpering and panting.
His stomach expanded so much it looked like the boy was pregnant. He then saw the group surrounding him and spray their loads all over his body. Tails just smiled and even opened his mouth, taking some in. By the time it was over, he was a mess. His goggles were on crooked, his fur was messy and covered in semen, and his ass was a gaping mess, slowly leaking out Wily's and Dave's cum, his stomach going back to normal as a puddle of cum was on the floor.
"You know what, Wily? I think your right. He'd be a perfect addition as a stress reliever. And I think he doesn't wanna leave yet, right Tails?~" Dave says and chuckles, seeing the fox shaking his head. His heat finally gone, but now a new feeling arose within him. "I wanna stay...~"
[...]
Time has passed since Tails' heat session. Whenever he's not busy or when foiling Eggman's plans, he leaves his workshop and goes towards Dave and join the Lightning Bolt Society. He was an honorary member and deemed the Society's cumdump, to use however they see fit. He catered to the member's needs and even used as a toilet.
During special events, Tails was placed into a stockade, his hands and head bound and exposed to all. He had writing on his ass with markers with words like; 'SLUT' 'WHORE'. "CUMDUMP', 'FREE BOOTY', and 'SONIC'S #1 FEMBOY'.
Right now, Tails was having his throat facefucked by one member and another pounding in his eyes. Tails just took it and the Society member with lustful half lidded eyes, his cock twitching and leaking pre. Dave, Wily and the Weasel Brothers watched as their fellow members enjoyed the new addition.
Tails even brought up an idea to rope Sonic into this and join him as another cumdump. He even had the perfect plan for them. The two tailed fox gulped down the male's load only to be shoved with another cock, giving him no time to rest. He closes his eyes and smiles, eagerly sucking away.
'Fuck, I love being a cumdump... Sonic... please join me, ehehehe~'
THE END...?
