A/N: My many thanks to everyone who has reviewed this story, the reviews and follows do inspire me to continue. My apologies for the infrequent updates, RL issues, etc.

But as a special treat this chapter is much longer than usual, over 3,000 words and I have already completed part of chapter 13, so you probably won't have to wait long to read the next chapter.

I may start to depart a little bit from the cannon plot in places and will be skipping parts of the original manga. But overall I think you will find my erotic back-story will eventually tie back to the original manga plot.

Warning: there may be a few minor spoilers in this and upcoming chapters for those not up to date on the manga.

Please review if you like it.

The Secret Life of Hilda and Oga - Chapter 12

I saw Lamia eye the camera on her desk and make a lunge towards it. Fortunately, I was closer to her desk and despite the handicap of having one hand between my legs; I calculated that I might still have a good chance of getting it first. I glanced over to see if Alaindelon was doing any better. Under normal circumstances, Alaindelon with his dimensional transference ability could have simply teleported to the camera almost instantly. However, drunk with whatever that succubus vampire Meridiana had done to him, it looked like he was moving in slow motion. He was definitely not going to be any help in this situation.

My shout that there was an "Emergency" bought me the split second I needed. Lamia paused just for a moment, perhaps a reflex action from hearing the word "Emergency", before ignoring it and continuing. This allowed me to reach out and snatch the camera from the desk first.

I turned to Lamia intending to savor my triumph - only to see her calmly pull her iPhone from her lab coat pocket and begin snapping dozens of photos. As she snapped photo after photo she swiveled between Alaindelon wearing the red panties on his head, still sporting a stupefied grin, not to mention the giant tent in his boxers, and me – buck naked, my bare breasts heaving from the recent exertion, long blonde hair loose and unkempt. I became acutely aware of the cool wet feeling on the inside of my thighs which no doubt were very visible lines of cum dripping out of my pussy. Of course, there was also my hand clamped over my pussy holding the rest from gushing out.

I started to move towards Lamia only to realize that every move I made gave her a new angle and view to snap. She even had the temerity to dance around behind me to get a good picture from my rear. I tried to imagine what those photos must look like; unlike the views from the front, which had my hand mostly covering my lower privates, the rear view would show almost everything in explicit detail. My stance, leaning over, legs spread in a position designed to help me spring to attack, I realized, was not in any way helping my modesty.

I was livid; Lamia's lunge towards the camera on the desk had been a brilliantly executed feint. My instinct now was to spring at Lamia to grab and crush the offending iPhone camera, but before I could do so Lamia said, "In case you were thinking of destroying this, you should know that the photos are being instantly uploaded to an off-site backup. Besides, if you destroy this rare inter-dimensional phone, you are going to lose the only means to call Oga in the human world."

I could do nothing except to stop and try to calm down - I had been completely outmaneuvered. Seeing the rage on my face, Lamia lapsed into a friendly grin and said, "Relax, you're my friend - I'm not going to show these to anyone. They are for my own special private collection." Then pausing for emphasis she continued with a smirk, "Besides they aren't even close to being the most embarrassing photos I have of you."

I took a deep breath to calm down and relaxed my stance to a less exposed position. I always knew that under that sweet innocent look, Lamia had a perverted side; but now I had to wonder what kind of perverted demon she was. Furthermore, I had always suspected she had embarrassing photos of me, but now I had positive proof. My mind raced to think what kind of photos could be even more embarrassing than this.

There was nothing for it but to bide my time. Eventually I would find an opportunity to find something equally embarrassing to hold against Lamia. However, for now it seemed I was losing the battle - badly. In my favor, I did have that incident when Lamia accidentally drank Oga's aphrodisiac sperm and ended up masturbating like crazy in front of me, and the fact she let me lick and suck her to orgasm. There were also a few embarrassing incidents from our younger days, but I realized had no physical proof while Lamia it would seem, had many photographs. Well two can play at that game, I thought to myself.

"Alright, back to business." Lamia said switching to her professional tone, " Alaindelon, I believe it is time for your annual physical examination... let's start with getting your sperm sample." Lamia then selected a glass container about the size of a vitamin bottle from a shelf. Glancing over at the gigantic bulge in Alaindelon's boxers; she seemed to change her mind, put it back and selected a pint sized jar instead.

"Alaindelon, go to room 13A down the hall and fill this up. Feel free to use any kind of pornographic stimulation available in that room." With a deft movement, she yanked the red panties off Alaindelon's head and before he could protest, handed them back to him. "Use these if you must, but try not to, or you might get addicted."

Alaindelon dutifully trundled out of the room jar in one hand and panties in the other. I tried very hard not to think of him grabbing his penis and jerking it off into that giant jar. It wasn't that I had any aversion to guys masturbating, after all I had watched many men do it during surveillance operations, and of course watching Oga do it actually made me extremely horny. It was just that Alaindelon was well... just not my type, or maybe it was just that he was too creepy for my tastes.

"Since when does a male physical examination require sperm samples?" I inquired suspiciously.

"Well, it is a normal part of the Incubus physical examination regime."

"Excuse me? Last I checked Alaindelon doesn't go around seducing women for their life force."

"Oh hush." Lamia whispered, "Do you know how incredibly rare Trans-dimensional Demon sperm is? This might be the only time I might ever get a sample. Besides, as far as I know, having Alaindelon completely empty his balls is the only way I know of getting him out of Meridiana's spell." Switching her expression to a mischievous smirk, Lamia continued, "Anyway, let's deal with you first. Let me guess. You're holding Oga's sperm in your pussy? How did this happen? I bet it hasn't anything at all to do with a sincere desire to bring me a sperm sample for my experiments."

I sighed. Putting aside my annoyance at being recently outsmarted by Lamia, I told her what happened leading up to my appearance here. Lamia and I may have our little rivalry going, but she was most definitely my best friend and I had to believe she would not betray me. As relayed my tale, Lamia grabbed a stainless steel oval bowl and bade me to squat over it and remove my hand. Translucent, milky white liquid gushed out accompanied by the heady scent of Oga's semen. The bowl almost filled to the brim before the gush receded to a drip. I squeezed to get as much of the remainder out and stood up relieved to have both of my hands free again.

"Amazing! There must be almost a pint of semen here." Lamia remarked as she carefully poured the liquid into a glass jar. "You must have been having a really good time with Oga," Lamia said in a voice which betrayed more than a hint of envy. After a pause she composed herself and continued, "This isn't ideal since it has been mixed with your fluids, but I think it will be good enough for my experiments. Ok, go ahead and get dressed while I prepare this for storage."

"So what do you think is going on? You weren't supposed to be here for another couple of days." Lamia said as I dressed and did my best to fix my hair up into a halfway respectable look.

"Apparently, the Great Demon Lord summoned me and Alaindelon grabbed me without any notice." I sighed. "How, much longer do you think Alaindelon will be? I need to ask him more about this."

"My guess is that he will be a while, Meridiana's effects are quite potent. Want to check?" Lamia asked grinning ear to ear.

"Don't tell me you have a hidden video camera in that room?"

"Of course we do... just a security precaution of course. We would never think of using it to spy on our patients for voyeuristic sexual purposes." Lamia said with feigned innocence.

The image of Alaindelon jerking off into that jar with Meridiana's panties pressed to his nose forced its unwelcome sight into my brain. "Uh, no thanks Lamia."

"Awww, come on, aren't you just a tiny bit curious what his big thing looks like?"

"Absolutely NOT. It would give me nightmares. Seriously Lamia, you really need to get a boyfriend and get regularly fucked."

To my surprise, Lamia looked depressed for a moment and said, "Yeah, I guess you're right," then in a whisper to herself she said, "Easier said than done." Quickly switching gears she announced, "Well, if the Great Demon Lord summoned you, most likely it was one of his Aides who relayed the command to Alaindelon. We should call them right away to find out when and where you are to appear."

After what seemed like an eternity while Lamia was transferred from one Aide to another, there was finally a heated exchange with someone who apparently knew something.

"Un-fucking believable!" Lamia screamed, slamming down the office phone in an uncharacteristic show of frustration. After venting about the stupid bureaucracy which surrounded the Great Demon Lord, she proceeded to explain that the Great Demon Lord had heard that I was coming to the Demon world for training and had asked to see me. The Aide had taken it upon himself to summon me early to get me in the queue and presumably, to keep his ass from being flame broiled if I arrived late. The Great Demon Lord was currently away at a Lava Spring with his harem for at least 2 days, but even so, I was to stay in the Demon world to keep my place in the queue and just in case the Demon Lord came back early and asked for me.

"So you mean I was rushed here in this state because a bureaucrat wanted to cover his ass?"

"Yup... well, look on the bright side we have two days to figure out how to deal with the problem of Oga releasing his sexual energy while you aren't around. The only thing is - you'll have to do it from the Demon world."

I had to breathe deeply to calm my anger. I had relished the thought of waking up with Oga and having another round of sex. Instead, I had been rudely whisked away in the middle of the night with no preparation or notice, only to be subjected to a humiliating defeat by Lamia. I resolved that if I ever found out which bureaucrat was responsible, I would find a way to flame broil his ass personally.

The lack of sleep, the marathon sex session with Oga, and the stress of the recent events were beginning to get to me; I felt exhausted and was ready to curl up on the floor to get some rest.

Noticing my fatigue Lamia said, "You can stay at my place. We'll go as soon as Alaindelon returns."

As if on cue, Alaindelon stumbled into the room with that gigantic jar almost full of milky white liquid. He seemed exhausted and his body looked shriveled. However, I did note with relief that the expression on his face looked like he was back to normal and there was no tent in his shorts. Lamia took the jar, quickly labeled it and put it into a cleverly hidden refrigerated compartment in the wall. I noticed that Oga's sperm sample was there too. Then Lamia handed Alaindelon some medication gave him some instructions and lead him out of the room.

"Is he going to be alright? He looked terrible." I inquired.

"Yeah, don't worry he'll be fine eventually. The medication will replenish the nutrients he lost, however, the life force he gave up will take at least a few of days of rest to recuperate."

It was obvious Alaindelon would not be able to transfer me back to the human world anytime soon.

"Alright! Let's head home. "Lamia said as she pushed me out the door and locked up.

There was only one bed in Lamia's home. She immediately rejected my offer to sleep on the sofa. "Don't be ridiculous, I can't believe you're even suggesting that after all this time as friends."

We ended up sleeping next to each other in her bed, naked as most of us demons liked it. Lamia no longer seemed to mind exposing her naked body to me, or maybe she was just too tired to care. It wasn't the first time I had slept over in Lamia's bed; after all we had grown up together and had many sleepovers. However, this was the first time Lamia had thrown away her inhibitions about showing me her nakedness. I was even more surprised when Lamia cuddled up to me and whispered sleepily in my ear. "Hilda, I know we fight sometimes, but I really do love you." Despite the fact that I could feel her small breasts on my skin and her pussy pressed against my thigh, it did not feel sexual. Rather it felt like a genuine expression of affection from a lonely little girl.

I knew in that moment, that Lamia would be a true friend to the end. As I started to fall asleep I whispered back, "I love you too Lamia."

My sleep was deep and relatively dreamless. I awoke feeling refreshed, horny and very much looking forward to a morning fuck with Oga when I realized where I was. To my surprise I turned my head to find Lamia moaning and squirming in the bed next to me, her eyes were shut but her face was contorted in pleasure. Lamia must be masturbating, I thought. Hell, I knew we had passed a new threshold in our friendship the other day, but to masturbate next to me without the aphrodisiac effect of Oga's sperm to lower Lamia's inhibitions seemed quite bold indeed.

The Hell with it, I decided and began to finger the itch between my legs. My fingers circled my pussy lips feeling the wetness while I relished the exquisite tingling feeling it brought. I inserted two fingers, then three. I moved them in and out in a slow motion while I fantasized that it was Oga's cock teasing me. I was dripping wet and somehow the sounds of Lamia's moaning excited me even more. Fantasy images of Lamia having a threesome with me and Oga floated through my mind. A fantasy began to form - Oga's cock pounding Lamia's tight pink pussy while I sat on Lamia's face having my own pussy sucked by her. To my surprise I found it a ridiculously powerful turn-on and it only took a few flicks across my clit with my other hand for me to reach a blissful orgasm.

I doubted that I would actually like Oga fucking another woman in real life, but in a fantasy, somehow it seemed all right. On the other hand, maybe, just maybe, it would be okay if that woman was Lamia. I thought on that a bit, bringing back the image of Oga's cock sliding in and out of Lamia. In my imagination, I could now see in exquisite detail as Lamia climaxed over and over again until Oga also came shooting his sperm deep into Lamia's womb. Before I realized what I was doing, I was climaxing repeatedly as my fingers rubbed furiously.

With each orgasm, I changed my fantasy. One had Oga fucking me while I sucked Lamia to orgasm while she squatted over my face. Another had Oga on his back with Lamia riding his cock while Oga sucked me to orgasm. There was no doubt, the perverted thought of watching Oga's cock plunge into Lamia's tight pink pussy really pushed my turn-on button. After my umpteenth orgasm, I finally felt somewhat satisfied. A little guilty for my perverted thoughts, but hey what was a girl supposed to do when her friend is moaning and groaning in sexual ecstasy next to her.

I looked over at Lamia who was still moaning and writhing away. She obviously had not even realized what I had been doing. To my surprise, I now noticed that both her hands were over her head grasping the headboard. Strange, it would not be easy to masturbate without using her hands, and lying on her back, she could not be humping anything. I decided that perhaps she was using a vibrator. My curiosity getting the better of me, I pulled back the covers on Lamia's side of the bed. She had her legs spread wide and her hips were bucking as if she were having sex, even the lips of her vagina were spread apart and moving as if something was plunging in and out of her, but there was no visible vibrator.

Was Lamia being assaulted by some invisible demon? I had never heard of any demons that could manifest at this level of total invisibility. Even an Incubus, which would have been my choice suspect, had to manifest physically to seduce their prey. As I watched perplexed but also mesmerized, Lamia squealed, and her body spasmed hard in an intense orgasm. What was even more amazing was that the invisible motion between her thighs looked like her "lover" had also cum and there was even a trickle of milky fluid, which looked suspiciously like real semen, coming out of her pussy.

"Oh my, that was the most incredible dream." Lamia sighed.

"Uh, Lamia, I don't think that was a dream." I said.

It took a few moments but all of a sudden Lamia opened her eyes and sat bolt upright. She took in the sight of her spread legs and the sperm that had now dripped out and accumulated in a puddle under her pussy. I could see her mind working furiously and an expression of alarm crossed her face.

"We have to call Oga now!" Lamia said as she leapt out of bed nude dripping cum from her pussy. She didn't even seem to register that she was presenting me with an extremely lewd view while she scrambled through the pile of clothes on the floor to find her iPhone.

What the hell? What did Oga have to do with Lamia's "invisible" fuck.
