Update: I added something raunchy at the end because I forgot to put it there in the first place.
Just to point out some facts before reading this about Kevin being a Cerberoan.
He's taller then Ben, also he'll have four arms which is pretty weird to see.
This is due to the blood he drank and no he's not a vampire for doing this!
The only one I've seen in a cartoon was in the Mighty Max cartoon series great show by the way.
In which Max had to figure out who was this three headed werewolf who was killing people in a small town of Scotland.
It turned to Be Professor McDoogle, a female scientist obsessed with werewolves that made a serum to become a super werewolf.
The idea of a scientist making the serum out of werewolf blood came from that which I used for the Ben 10,000 chapters I wrote.
Anyway I talked too much go check out the series it can downloaded, but it takes a long time. Totally worth it though my opinion.

Both Cereboans circled each other, watching for the right moment.
It was like watching one of those documentaries on the discovery channel.
Kevin hoped Ben would recognize him, but without the collar it would take longer.
He noticed right above Ben's stomach were two bumps under his pecks.
Ben just growled not liking the location of the gaze from the other.
For some reason this wolf seemed familiar, but his mind was clouded.

" Benji stop. You need to change back and come home."

" How do you know me? Why do you smell familiar?"

Ben sniffed Kevin's chest then his crotch making him pant and whine.
He looked down feeling lust rush through his veins and hoped it would go away.
Then Ben felt anger as images of them at the store where girls would openly flirt with Kevin who just stood there unresponsive.
Ben would just sigh grabbing Kevin's arm pulling him away feeling ignored.
Ben was worried that Kevin would leave him just to be around thin, attractive girls.

( Lousy hormones stop messing with Ben! Ben knows Kevin won't leave him, but that's why it sucks being pregnant!")

" It's me Kevin. After all we've been through how can you forget we're a couple?"

" If we are then why do you let whores flirt with you? Why do they touch you and you let them while I'm standing right there!"

" I'm not interested in women Benji you know that!"

" Oh I see it's because I'm pregnant isn't it? You don't find me attractive anymore!"

" That's a lie! I get hard just seeing you sitting or lying on the bed."

" Then why do I smell Gwen on you? I should have known she did a spell on you cheater!"

" Ben I don't like her at all! She's a bossy, uptight Anodite ice queen!"

" Then prove it! Show me that you look at me and only me Kev!"

Suddenly Ben tackled Kevin and they wrestled crushing light poles and some poor cars.
While this was going on Gwen was watching Albedo and Lance beat the crap put of Cash and J.T.
She healed Cash's bones after taking a picture and made them unable to move.
Gwen was enjoying hearing them scream as they were tenderized like meat.

Kevin managed to pin Ben on his back being careful with his stomach.
Closer inspection on Ben revealed he had two more sets of nipples.
Curiously Kevin gently touched one getting a loud whine from Ben.
Smirking Kevin started rubbing it making Ben whine louder and squirm.
One pair of arms held Ben's above his heads while the other pair was teasing Ben.

" You have six nipples now. Wonder how sensitive they are?"

" Don't tease me you pervert! You know I hate it when you do that."

" Now you remember me huh? No one else can do this to you."

Ben howled as Kevin sucked on one of the nipples while his hands rubbed the others.
Ben thrusted his hips making his erection hit Kevin's and both of them groaned.
Cash and J.T. were all glued into the costumes and unable to move.
Gwen, Lance and Albedo were wondering how did a fight turn to this?

" I swear they have too much energy!"

" See what happens when hormones take control!"

" I don't hear you complain about it!"

" I heard their argument before this. What do scents have to do with it."

" If they find another scent that doesn't belong, they think their mate cheated on them."

" Haven't you noticed Ben growling when someone touches Kevin?"

" That does explain alot. Also why Kevin does the same thing."

" I'm surprised Ben hasn't attacked you for touching Kevin."

" It's just his shoulder that's all. What harm could that do?"

" You're making Ben think Kevin wants you. And with Ben being pregnant, his hormones are messing with his mind."

" Pregnant women aren't considered attractive. Being around thin girls makes Ben think Kevin will leave him because of it."

" I had no idea. I feel bad about this."

" Looks like Kevin found some more changes to Ben."

" He's just licking Ben's stomach. Is anything else going to happen?"

" Well Ben has more nipples now. When wolf babies are born they need milk so the mammary glands form before the babies are born."

" Wait are you saying my cousin is going to have breasts?"

" It's just for the children. Once they start eating meat then the glands go away until he's pregnant again."

" He'll have six nipples, but he is still a boy."

" I doubt there will be more kids. Kevin's bought a ridiculous amount of condoms."

" Now the real question is how do we stop them?"

Both Cereboans were making out not caring if anyone came by.
Ben had his legs wrapped around Kevin who was grinding them both into the ground.
Kevin's four hands were massaging Ben's extra nipples getting different reactions.
When he started pinching them Ben unleashed a loud scream-like howl as he gripped Kevin's shoulders.

" NNNG! KEVIN!" Kevin pulled back as Ben released all over his stomach and waist.

Kevin then released all over Ben's area and stomach as well panting and smiling getting a wicked idea.
One head kissed Ben while the second sucked the cum off his nipples and the third giving him a blow job.
Ben's moans were muffled as he was suckled in three areas at one time.
No words could express the feeling and suction he was experiencing.

He felt so good that he came again for the second time in that day forgetting that his cousin and evil twin was in the area.
Once Kevin back away to let him catch his breathe, Ben sat up grabbing Kevin's hips as two of the heads suckled him hard.
Kevin made out with the third head while his other two heads howled with ecstasy.
They should have more fights in the future if this was the end result.

Kevin came and both sat down panting hard, but smiling from this experience.
Ben got up and presented himself to Kevin who nose started bleeding from the sight.
After he cleaned his nose, Kevin mounted Ben thrusting instantly into the tight heat while one pair of arms grabbed his waist in a iron grip making Ben whimper.
Ben screamed as the other arms were pinching and massaging his nipples with no mercy trying to move along with Kevin, but couldn't due to the hands.

Kevin licked and bite the back of Ben's neck enjoying the feel of being inside him.
It was like liquid velvet mixed with smoldering silk tightly squeezing his dick.
Once the grip loosened Ben started gyrating his hips to move along with the thrusts.
The gyration and heat made them sweat and their brains shut down from the pleasure.

What were the other doing you may ask?
Well seeing something this hot gets to you so why not remedy the problem.
Gwen was on the trunk of Kevin's no pants on fingering herself as the car rocked.
Albedo and Lance were doing it in the backseat making in rock heavily helping Gwen get herself off as well knowing this was wrong, it felt too good.

( Yeah people masturbating and consummating in the streets and they're not worried about being caught on camera or the police?... anyway back to the story!")

As night time was rolling in Kevin used one pair of hands to stroke Ben making him scream louder than before feeling their climaxes coming closer.
Soon both wolves tensed and howled their release falling to their side drained, but happy.
Kevin licked Ben's neck lovingly as his four arms wrapped around him to keep warm.
As the moon lit up the ground Kevin and Ben were in a deep sleep still intertwined while Gwen was asleep on the trunk.
Her hand covering herself while the two other wolves slept in the car.
Now the question is how are they going to explain what happened when either the cops, or the news comes to demanding an explanation!

Oh my head hurts. I have to take a cold shower, it's too hot lately.
Well I hope you like this chapter it gave me a headache.
Don't worry I'm fighting off a cold so it won't affect me updating my stories.
I appreciate everyone who reads this and I fell better knowing you like this story so much :)
