Yes, it's time for the finale. Let's see how much I can fit into this before I crash from too much caffeine!

Ben woke up with a smile in spite of the fact that he woke with Gwen riding his stiff morning wood. Tomorrow was the last day of summer. As much as such a thing approaching would depress him any other time, he would take it with a smile if it meant never having to deal with Gwen and her fucking alien forms and her damned whoring him out every day. He was pretty sure she was gonna have some big grand send off planned, but he could endure it, he knew he could.

Of course, Gwen had a plan for that, but it wasn't quite time for that yet. Right now she just wanted to enjoy a big blow out with her fuck toy of a cousin. She was glad she had discovered how to change from one alien to another at will without the watch ever timing out, as it would make all she wanted to do today so much more fun and easier to pull off as well.

Gwen moaned as she came, allowing Ben to cum inside of her before she shifted forms into Ghostfreak, floating not over to Ben, but to Grandpa Max. She used his possession ability to implant a few ideas in his mind, then floated out and returned to normal. Max had no idea it had happened, and though he couldn't figure out why, he was sure that heading out fishing for the entire day and leaving Ben and Gwen by themselves was a good idea that he had had himself.

Ben could have known it had been Gwen's doing even if he hadn't watched her do it. He wondered how much else she had been responsible for with her using Ghostfreak's possession. Regardless, Ben and Gwen were left by themselves at the camp they had set up. Gwen ordered Ben out of his clothes immediately and demanded she be eaten out. "I want to get off again before the others arrive~" She said.

Ben wasn't surprised to hear that she planned for others to be showing up. She would have almost been surprised if she hadn't sent out a message telling whoever she could reach to show up to rape him. Ben heard them approaching while his tongue was still buried in Gwen's cunt, and didn't see who they were until Gwen had finished, soaking his face in her juices and letting him look up. His eyes widened when he saw who all was joining them.

Frightwig from Zombozo's gang, Rojo the girl who'd been assimilated by one of Vilgax's machines, Pinkie the escaped prison lady, Xylene the alien girl who'd had the hots for their Grandpa Max, Turbine the trucker girl bandit, Tiffany from that snooty rich kid school Gwen had wanted to go to, and even Tini, the fourarms woman from the Galactic Enforcers team.

"I figured I should probably have a proper send off with girls we know~" Gwen said with a grin, turning to the women and letting them all know about the nanobots inside of Ben and how they worked. Rojo and Pinkie went first, Pinkie mounting Ben's face and Rojo ordering his cock up to eleven inches before dropping down hard. "No cumming until we're both done bitch." Pinkie ordered, groaning as she felt Ben's tongue push into her pussy.

Rojo was riding Ben's swelled cock in reverse position, her super strength letting her grind her pussy down hard on Ben's cock, taking his entire length deep and so hard he was sore in seconds as she rode him. Pinkie let out a string of insults and other humiliations as she rode his face, her time in prison making her used to such forms of domination of those she fucked.

When Pinkie came, she stayed on Ben's face, taking a page from Charmcaster's book and using his mouth as a piss toilet while Rojo kept riding his cock. The machine girl was bouncing so hard now that Ben's hips actually bounced off the ground with the movements of her sex, making her moan louder as she got closer. Rojo came right after Ben had been forced to swallow all of the prison girl's piss, sighing happily as she released over Ben's cock.

Ben's rod was twitching with the need to cum, but he doubted he would get is, as it was Frightwig who took him next. She ordered his cock another inch larger, causing even more pain as his member was forced to grow out further before she dropped her hips down hard to ride him, her tentacle like hair coiling around him like bondage chains. Ben figured she just liked the feeling of having him bound as she rode him, as it certainly wasn't necessary to do so at this point.

Frightwig moaned as she moved her hips along Ben's length, using her hair coils to make Ben move his hips with her, squeezing his sensitive body tight with each movement. It felt like he was being lashed from every angle from how hard her hair coils squeezed him. Frightwig seemed to enjoy this though, and came all the faster because of it. She unbound his body as she dismounted and let the next two go.

It was Tiffany and Turbine who went next, Tiffany taking his face and Turbine his cock after lowering it back down to ten inches. She liked it rough but she was still human. Once again Ben was tortured more by the woman on his face than on his cock. Tiffany seemed to relish in insulting Ben as he ate out her cunt, which made her behavior back at the school make all the more sense in retrospect.

Tiffany to decided to repurpose Ben's face as a toilet, but unlike Pinkie, didn't just use him for one form. Ben squirmed and writhed beneath them in revolution as he was forced to swallow waste from both sides of the prep girl, who sighed happily in relief, getting off on his suffering. Turbine enjoyed it as well, Ben's squirming pushing his cock up deeper into her pussy.

After Turbine came and dismounted, Xylene went up to him. "Poor thing," She said, seeing how much his cock was throbbing. "You can cum just as soon as I do." She said. She didn't want to hurt or torture Ben, but the lust chemical the nanobots let out made raping him her first priority. She used her psychic powers to lift Ben into the air with her, locking her legs and arms around his body so she could take his cock, now swollen to a full foot in length, as deep and rough as possible.

Ben whimpered and pleaded with her to let him slow down or to go slower herself, feeling that Xylene might be the one person here who would actually let up. No such luck. Her only responses were, "Just a little longer Ben, try to hang in there," or "It'll start to feel better if you just relax." At no point did the pain or exhaustion subside and yield to pleasure, and the alien women kept going for a full hour.

She did allow Ben to cum deep into her at the end of it, but by that point he was so pent up it didn't even feel good anymore. Xylene lowered them to the ground, sighing happily as she dismounted and Tini walked over, licking her lips as she requested his cock grow as large as possible. His member inflated up to over a foot and a half in length and she dropped down hard onto it. "Cum as hard and as often as possible~" Tini demanded, wanting her pussy full to the brim with seed.

Just like with Gwen when she was Fourarms, Tini took forever to satisfy. Not only did it take over an hour and a half to fill her cunt with seed, but when it had been filled, she turned around and demanded that Ben fill her ass up as well. Thankfully it didn't take as long as her pussy, but by the end of it Ben's balls were more sore than they had ever been, which was saying a lot considering how he had just spent his summer.

Ben collapsed on his back, panting hard as he tried to catch his breath and outlast the pain. He was thankful when he heard the other women leaving the area, but his disappointment returned when he felt Gwen standing next to him. "You aren't done yet stupid," Gwen said with a smirk, lifting the watch and shifting forms into the blue anthro wolf they had labelled quite simply Gwenwolf.

Gwen lowered herself down, beginning to ride Ben in wolf form. Her body was so hot and tight in this form, and she rode with almost as much strength as Tini. Still, Ben felt he could tolerate one more round without blacking out completely. Of course, even if he couldn't he wouldn't actually be able to black out, the nanobots wouldn't allow him that much rest unless Gwen allowed it.

And of course she didn't. When she saw that Ben's eyes were glazing over in desperate need of rest, she simply ordered the nanobots to increase his sensitivity and rode harder until she had finished cumming and gotten bored of the wolf form. She stood from Ben's cock, shifting aliens into another one she had gotten through copying one she had seen, the Stein alien that had been working for the renegade Ghostfreak.

She dropped back down again, making Ben yelp. Not only had the sensitivity been cranked up, but Gwen in Stein for weighed almost twice what the wolf did, and generate large amounts of static with each movement, causing her to shock his cock every time she bucked her hips to take him deeper, which she did every second until he was hilted inside of her pussy, at which point she could shock his entire cock at once as she rode him.

Gwen stayed in Stein mode for a good hour and a half, not letting Ben cum until the end of it. As painful as the experience was, Ben assumed Gwen was done with him after it was over, as she stood up from his cock and shifted out of Stein form. He didn't realize how colossally wrong he was until he saw her looming over her in the massive form of the alien called Waybig.

Ben didn't see how on earth she could possible use this alien for sex. His cock could grow big now but not that big. Ben thought for a moment that she had seen something happening and had switched to Waybig for a fight, but realized different when she picked him up, bringing him between her legs. Gwen moaned as she felt Ben's head and torso push into her pussy as she used his entire body as a dildo, making him her literal sex toy.

Gwen couldn't hear it, but could feel him freaking the fuck out as she forced him deeper into her pussy. Nothing he did could hurt her in any way, but his panicking did make her pussy feel better, and so she pushed him as deeply inside of her as he could, holding onto him by his foot. Gwen groaned, just enjoying the feeling of him squirming inside of her cunt. He wouldn't die from this. The biggest risk to him was suffocation, and the nanobots could easily prevent that. It would hurt like hell, but he'd live.

When she came, Ben was forced out of her by the veritable flood of juices from her cunt, which soaked the campsite beneath them. Ben laid prone in the center of it, sputtering and sobbing and panting. His eyes were completely glazed over, broken and unable to respond as Gwen shifted back into human form and laid on top of him to rest for a bit.

As horrible as everything had been, Ben felt that he was finally safe now that he was in his own bed in his own home. He did, of course, have a few nightmares throughout the course of the night. He didn't mind them though. Fuck he had been expecting them and wasn't expecting them to go away any time soon, not after everything he had been through.

What Ben did mind though was when he woke up. His eyes widened when he realized that not everything he had been dreaming during the night was just a dream. Instead of it being Gwen on his cock when he opened his eyes though, it was his own mother, stripped naked and riding him just as roughly as Gwen had all summer. "M-Mom?! What are you doing!?" Ben questioned, struggling to get her off of him.

Ben's mother held his arms down, groaning as she came and continued to ride him, "I-I'm sorry son, I just missed you so much, and you got so cute over the summer, and you looked so adorably helpless while you were sleeping, I couldn't stop myself, it feels so good!" She moaned, continuing to ride him. Ben knew what this was, it was that damn lust chemical in the nanobots. This must have been Gwen's plan Ben thought, to make sure he never got any rest even if it wasn't her doing the fucking.

As it turned out, he was only half right. When morning finally came and Ben's mother stopped fucking him, she told him what Gwen had done with all that money she had saved up over the summer, "Your cousin paid for you to go to one of the best schools in the country with her. She's going to, but she must have spent a ton for you to get to go, because it's an all girls school."

Ben's blood went cold as he realized that his cousin's plans for him weren't even remotely finished yet.

And that's it! Sorry if quality was a bit stodgy here and there, like I said, I'm writing this towards the end of a coffee marathon. In fact, these chapters were all written in two quick clusters so they could all be done at once before I even started the story. I hope I did okay in spite of this. If I didn't, be sure to let me know in the reviews. If I did, let me know what your favorite chapter was, or if there was a chapter you would have liked to see.

Also, if you'd like me to write more Ben 10 stuff, tell me what kind in the reviews. Also don't be afraid to suggest other properties I could write domination fics about if you want. If you've made it to the end of this story, then no one who sees your review is going to judge you for whatever you suggest, least of all me.

I am sinful by nature with no malicious intent, and I'll see you all next time!
