Hey readers
Sorry for the long wait for stories, mind's been all over the place. But I do have more ideas coming, for now please enjoy this new Ben 10/Monmusu crossover.

"Mmm..." a voice groaned, looking in what seemed to be a freshly constructed room we see a young man by the age of 17, he had brown hair, a rather well developed physique and as he began to wake up, emerald green eyes. And looking at his left arm sticking out of the blanket he was using, an odd looking gauntlet like device.

This here was Ben Tennyson, at first glance he's your average teenage boy, if you think that you'd be wrong. Benny here is more than a mere teenage human, about seven years ago while he was on a road trip with his grandfather and cousin, Ben found a watch like gadget that crashed on earth from space. When he approached it, the thing latched onto his wrist, and gave him the power to turn into a member of of 10 different alien species, each with their own powers and abilities. As time went on Ben began to amass all sorts of new and very amazing alien forms, easily becoming the hero of the universe with how many times he's beaten bad guys and villains.

Like for instance, just last year Ben defeated his arch enemy, a squid like alien named Vilgax, but in doing so had to sacrifice the Omnitrix. However as a positive, he managed to get the Ultimatrix, a copy of the Omnitrix that not only transforms Ben, but evolves his alien forms into their most powerful forms.

At the moment, once he fully woke up, Ben found he wasn't able to move. Looking to his side, he saw a rather princely, but decidedly female face with green scales on their cheeks and blonde hair sleeping next to his own, and the person happened to be cuddling him. Which explains why he wasn't able to get out of bed, in response he blushed and attempted to wake them up, "er, Draco... it's time to get up now" he said. The person, now identified as Draco, moaned in response and spoke "not now stud, give me five more minutes... better yet let me warm up five more degrees" she said in a female voice. Now cementing Draco was a girl, and looking under the covers, her panties, cute pajamas, feminine waist and butt now confirms. With the addition of her dragon like tail and wings, along with the scaly arms and legs.

Not too long ago, around 3 years in fact, a legislation dubbed the interspecies cultural exchange bill was passed allowing various earth native non human species such as Mermaids, Centaurs and other related mythological races, to live among humans. Since then not much change has happened to the world, in order to do so, Members from various species were to live with a human host family in order to experience different life styles in different parts of the world. Which is why Draco is here, she's a Dragonewt, a type of human like dragon species or Linimal, who was living with Ben in order to not only learn about human culture, but to also help form an alliance with the Linimals on earth with the aliens from space.

Apparently Max wanted to form the alliance that way some day Aliens can live among humans as themselves without needing a disguise as they have been for so many years. So he signed his grandson up for the exchange, honestly Ben was surprised the peace had been going on for this long, especially with the Forever knights still out an about.

As for he and his exchange's relationship, when Draco first arrived they've been a bit rocky, due to the fact she didn't like men very much, and probably thought Ben wouldn't accept her. Especially due to a little hiccup on her track record involving an accident in Japan involving trying to take a Lamia, snake woman, as her bride against her will. However, knowing how our favorite shapeshifter was, he actually made sure her stay with him was comfortable. This surprised Draco, even with her bestial appearance and when her coordinator mentioned that incident, Ben still treated her like a normal girl, albeit one who looked cool with her draconic features.

Not only had this caused Draco to hold Ben in high admiration, but also caused her to have a crush on him, which was pretty obvious. In spite of her tomboyish tendencies and attraction towards girls, she felt a strong pull towards Ben and had wanted to express it. Her method at the moment though kinda involved a lot of cuddling, with the wings on her back enveloping him and her tail wrapped around his legs. "H-hey wait?! What are you doing in my room?!" He asked surprised, "sorry but it's been really cold lately I had some trouble warming myself up" she explained adjusting her position to sand her torso up with her elbows. "So I was hoping you could help me out a bit", he then sat up and attempted to exit the room "uh sure I'll get your heating apparatus-WAH?!" "I don't think so!"

The dragon girl yanked him back into her arms and nuzzles her face into his neck, "mmm, it's always nicer when you warm my up stud muffin" she said blushing feeling his breath running down her back. If that wasn't enough her pajama shirt was wide open and her tiny bra was dangerously close to slipping off, small chest or not this was something Ben could easily feel rubbing against his chest and abs. Due to her pulling her shirt up to slither into it, 'crud this is feeling really nice! Okay Tennyson, gotta figure a way out, she may have a grip but you're the stronger out of... Eep?!' He was cut off when she moved far to face with him and gave his cheek a small kiss, "oh crud, come on Draco. Get up, if you do I'll make you that breakfast you've been wanting for some time" he said, "hmm, dream food or more cuddles... okay fine you win" she said sitting up "thanks" he said sitting up also, then felt her bite his ear a bit causing him to Yelp. "Thanks stud" she cooed before walking out.

"Jeez, feels like that girl will be the end of me" Ben said changing.

After getting his reptilian roommate's bath ready he went to the kitchen, due to the insufficient size of his old house as most Linimals can be rather large, Ben's new Interspecies Exchange Coordinator had made a larger house for Ben to live. In order to accommodate for any future Extra species moving in, "man this morning was rough, but I guess it can be worse. Least Draco was compliant enough to let me go" he said to himself as he made breakfast.

Thankful he had taken lessons at his school in the event he had to go on another trip with Grandpa Max, fearing the food he made. "(Shiver) though, it was pretty nice I'll admit" he adds, not aware of the extra presence in his dining room "oh I'm sure it was Stud" a voice said surprising him. "GAH?!?!" He looked back to see a very attractive black haired woman in an office suit wearing sunglasses, "oh come now, don't tell me you forgot about me. Kuroko Smith, your interspecies exchange coordinator" he said adjusting her legs.

"Oh trust me Smith I hadn't forgotten, question though why the heck are you in my house?" Ben asked panting as he was trying to stand up. "Any chance I can get some coffee?" She asked holding up a coffee cup "this isn't a cafe you know" he retorted... then had obliged her request "cream or sugar?" He asked begrudgingly. She smirked and replied with cream, "so Miss Smith really, why are you here?" Ben questioned.

"I simply came to check up on Draco, in addition to making sure you weren't doing anything prohibited" she explained, "while I appreciate your concern for Draco I can assure you that I hadn't harmed a hair on her head nor had made any attempt to assault her" Ben replied. "Good to know, still I won't blame you for doing that" she says smirking again, but this time in a goodnatured way, "while Draco isn't as full bodied as most girls she's certainly got her finer points. Her face is still rather pretty in a tomboyish way, her frame is so dainty she almost looks like a young girl, and let's not forget her a** is fantastic" Smith said making the hero blush as he used Four Arms' form to hide it. "You ain't exactly helping with that you know" he said "ooh I was wondering when you were gonna show me one of your alien forms" she said rather impressed. Especially looking at all his muscles, "in addition though" she then appeared behind him as he turned back, then surprised him by turning his face to hers, which was very closer.

Causing him to blush as their lips were only an inch away from each other "you're quite handsome and very easy to fluster" before any further moves can be made a green tail snatched Ben's wrist and pulled him into Draco's wings. Who was done with her bath but in one of Ben's white T-Shirts and was soaked "the heck are you doing Smith?! If you think I'm gonna hand over my stud that easily you've got another thing coming!" She yelled. "Oh relax I was only kidding" she said before letting out an unnoticeable "Tsk!" 'Shoot, I was so close to a small lip lock' "I need to head out anyway" she then grabbed her coffee cup and headed out. "Remember Ben kun, no hanky panky stuff" she teased before leaving.

An awkward silence lasted about five minutes before the hero spoke up "oh uh, Draco I think you should go change. You're gonna get cold and tired in those clothes" he said. Only to feel her hug him tighter, "i heard what Smith said" She said, confused he looks back at her and sees she has a depressed face. "It's obvious I'm not as hot as most girls. And that I look like a guy, plus the fact I'm just a lizard with wings... not to mention the big mark on my track record. Yet despite all of that, you were always nice to me..." Draco said. Ben, wanting to make her happy again, turned around and gave her a one armed hug, "just because others might think you're no good, doesn't mean you are Draco. While you didn't look very cuddly, I still though you were pretty cool, and I'll admit I was a bit hesitant when I heard about that incident you were involved in, but I also knew the reason you did that was just because you wanted a friend" he said as she blushed listening.

"Even if you have some rough edges it doesn't mean it's bad, besides" he then looks at her with a smile, "that's just what makes you you Draco. And to be honest, I kinda like the person I've come to know, past your bravado, I saw you were a kind girl who's charming in her own way" he says as she hugs him tighter. With her smiling and crying happily, "how did I deserve someone like you?" She asked, then wraps her tail around his torso and pulls him to the floor before topping Ben. "H-hey Drac-mph?!" He was taken aback when she had kissed him, after pulling off she wiped her mouth and smiled at him. "By the way that was my first kiss, want to take my second?" She asked leaning it, before he could even answer Smith came back, scaring them into separating. "Oh by the way Ben, I almost forgot, the other reason I was here was because the exchange was looking for trial couples for Extra species and humans. So because of that the rules regarding sexual interaction have relaxed a bit, so if you two want to yah can do it. Bye bye" she said. Then noticed their position, "by the way are we still on for that breakfast?" She adds, ruining the moment.
