"Master-kun, wait up for a second!" I hollered down the hall, waving my hand.

Ahead of me, I saw the dark haired boy pause for a second before rounding the corner. He looked back over his shoulder and smiled. "Cu Caster! Sorry, I didn't see you there. What do you need?"

I felt a little leap of joy at the nick name. In my day I had become so famous very few dared to act familiar with me. I had grown sick of formalities, and the endearing term left me a little nostalgic for my lost boy-troop. Yet, this did little to calm the anxiety I was carrying about the question I wanted to ask Ritsuka-kun. Pinching my thumb and index finger together, a nervous habit I hadn't been able to kick, I steeled my resolve.

"I'd like to ask you a question, but it's kinda personal. Is there somewhere we can go?"

"Sure." Glancing around, Ritsuka-kun spotted the open doorway to our left. "No one seems to be in this research room at the moment. How about we chat in here?"

I nodded in agreement, my hood shifting lightly around my ears. Intentionally, I had covered my very noticeable, blue hair to avoid attention. Not that my hood had become any less distinct at Chaldea. I followed master into the study and paced the room while he shut the door.

"What's the matter Cu? I haven't seen you this agitated before. Not any of you for that matter."

Again he used the pet name. I had a sneaking suspicion that master was trying to put me at ease. Was I really exuding that much of my internal turmoil?

"I've got something on my mind. Something I've been thinking about since we played Truth or Dare that one night," I admitted, finding myself dancing around the subject like a nervous school boy. I felt pathetic.

"But that was weeks ago," Ritsuka-kun muttered to himself. "Wanna sit down Cu?" he asked, gesturing to one of the rolling chairs.

I stopped my pacing and sat heavily in the chair. Yet I couldn't just sit still. I huffed and tossed my hood back, ruffling my hair in an attempt to calm myself. Sometimes I could be too easily frazzled.

"What made you sit with this for so long? You know you can always come to me for anything," my master said, also sitting in a rolling chair.

"Oh?" I said, crossing my arms. I was deflecting my insecurity with coyness.

"I extend that offer to all the servants here. You can tell me anything, and I promise I will do what I can to help. I may not be that helpful in the end, but I want to be available. That's the least I can offer you after everything you all have done for me."

I let his words steady me. Clasping my hands and leaning my forearms on my legs, I decided to let the words come out as they would. I had never been known for my subtlety.

"It's about the truth Ritsuka-chan asked of Gilgamesh, you must remember the one, when she asked if he had been sleeping with himself."

He nodded, encouraging me to go on.

"Well, the idea really interested me. It's been on my mind since then, and I'm sure it has for the others as well. I mean, they are me after all, and if it's been on my mind it will have been on theirs. Gah! This is exactly the problem!" I shouted suddenly. "I have been thinking too much. Whenever I'm around myself I feel self-conscious. I'm just not used to feeling so uncomfortable. With Lancer and Prototype it's not as much of a problem. But with Berserker-"

At this point Ritsuka-kun cut me off with an ironic laugh. "And here we all thought you three were already screwing each other!"

"We?" I asked, more meekly than I intended.

Master completely ignored me. "If it's Berserker you are worried about, then you can relax. Berserker won't do anything to you, I promise."

I tilted my head a little to the side, having absolutely no idea where Master's conviction game from.

"When we gained the ability to summon berserkers at Chaldea, Da Vinci altered the madness enchantment a little. When a berserker is summoned to our facility, the madness does not extend to their sexuality. In fact, it will have the opposite effect on their libido. Long explanation short, your Berserker form doesn't have sexual urges."

"Hum, interesting," I said, leaning back and crossing my arms. I couldn't decide if I was upset that some flimsy European mage had managed to magically castrate my alter or impressed at her capabilities.

"Imagine if someone like Tamamo Cat or Caligula still had their sexual urges. Just the thought gives me the shivers."

I could agree with him there.

"So don't worry about it Caster!" Ritsuka-kun seemed proud that he could reassure me so easily. "I hope I was able to help…." he trailed off, looking hopeful and insecure. After a short pause, he said "If that's everything, I do have something to take care of elsewhere." Mater stood from the chair and made his way to the door. "Thank you for coming to me with this Cu. I appreciate your trust in me," he said at the doorway, an embarrassed blush dusting his cheeks.

I listened to his footsteps echo down the hall, catching the light tenner of Mashu's voice when she said, "Senpai, there you are. Kiyohime is looking for you." Their presence faded shortly after that.

I stayed seated a moment longer, feeling as if a weight had been lifted off my shoulders. Not only did I feel like I could to stop avoiding Berserker, but I felt free to peruse one of my younger selves. Getting up, I strode down the hallway opposite the direction Ritsuka-kun had gone. Walking briskly, I tucked my thumbs into my belt and began to whistle.

I happened upon Lancer not long after starting my walk. He had been sitting in his room busy cleaning his spear. I decide to pop my head in.

"Ah, Gae Bolg," I commented longingly.

Lancer looked up. "Yeah," he smiled cheekily. "It may be in perfect condition, but I never tire of this." He looked down at the long, red spear lovingly. "Want to join me?" Lancer asked. It was no secret to him how much I miss my old companion, now that my class prevents me from summoning it.

I walked in and sat on the bed next to him, picking up a polishing cloth. Rubbing the material fondly below the hilt, I reveled in the familiar sensations of my old weapon. Gae Bolg felt exactly how I remembered. The sturdy wood, pulsating with divine power, responded instantly to my touch. Waves of power emanated from my finger tips and worked their way down the spear, strengthening the pole and sharpening the point. I smiled reminiscently down at my lap.

"It must be really tough being separated from our spear," my companion commented.

"Mmm," I grunted, noncommittally, eyes transfixed on the spear in my lap.

"Man, I really do look pathetic when I'm depressed. No wonder Medb is always trying to keep me happy."

I looked up at Lancer. He was tidying up the cleaning tools.

"Enough of this," Lancer said, dismissing Gae Bolg. "Let's get you cheered up. I'm sure, between the two of us, we can think of something. After all, you have quite a brilliant mind." As he said this, he ran a hand behind my ear, tucking a few stray strands of hair out of the way.

I shivered. The sly dog, he knew very well what that spot did to me. But this is a game he would not win. I was, after all, more experienced.

"You know," I said, reaching over and running a thumb under Lancer's lower lip. "I have had this idea for a while now…." I trailed off suggestively.

"Oh? Now what might that be Caster?" Lancer asked, sounding as if he knew exactly what I was going to say.

"Something that requires a little bit more privacy," I said, standing up and shutting the door.

When I turned around, Lancer was right behind me. "Well now Caster, I didn't know you felt that way about yourself." He smiled ruefully.

"Yes you did," I stated, watching as his lips hovered inches from mine.

"You want to try it then?" Lancer asked, just making the situation clear. "The thing master suggested to that golden narcissist?"

"Let's give it a go," I confirmed.

With permission granted from both sides, Lancer leaned in for the kiss. Attempting to get an early lead, the man pressed me against the door and shoved his knee between my legs. The sensation was fantastic, having both my balls and my tongue played with at the same time. He may be quick, but I was more level headed. I wasn't about to let myself become overwhelmed just yet.

Reaching up, I ran my fingers through the hair along his temples. I avoided the soft skin just behind his ears until my fingertips made their way to the back of his neck. Then I pressed my thumbs into the sensitive flesh just behind the jaw bone. Already he was shivering and losing track of the pace of his knee. Unwilling to let the pleasure between my legs end, I unashamedly rubbed myself against his leg. Slowly, I was beginning to win dominance in our mouths.

Testing out my power over Lancer, I began to guide us backwards to the bed. Upon reaching the mattress, Lancer immediately collapsed backwards. I swiftly crouched between his legs, watching his dilated eyes follow me closely. His face was already quiet flushed and he was breathing heavily. Placing a hand on each hip, I prepared to pull off his pants.

"Up," I commanded.

Lancer readily complied, lifting his buttocks from the bed so I could slide off his tight leathers.

"Good boy," I murmured, glancing up to see Lancers expression.

A small flicker of annoyance crossed his face while a growl formed at the back of his throat. Yet, the attitude is short lived as I shoved his hardened shaft deep into my own throat. The growl swiftly morphd into a moan as I began playing with him.

I am not unfamiliar with oral sex. When I was young, still training under Scathach, my best friend Ferdiad and I did all sorts of sexual experiments on each other. Therefore, not only did I know how to use my mouth, but I knew exactly what I liked best. I could picture the sensation so vividly in my mind I almost felt the warm pressure slipping across my penis. Just the memory generated pronounced stiffening in my groin. It was almost, and at the same time exactly, like I was sucking my own dick.

I decided to give him the look. The look that said was doing my best to hide how very turned on I was with just Lancer's dick in my mouth. The look that countless women, and even my poor friend Ferdiad, had given me long ago. It was a look that I knew would be absurdly seductive to my Lancer counterpart.

In response, he grabbed me under the chin and pulled me up. Grabbing me by the collar of my shirt, Lancer tossed me onto the bed. He made short work of my clothing. By the time I had come to my senses enough to take stock of what was happening Lancer had me almost bare before him.

"Hang on, why am I on the bottom?" I asked indignantly, noticing that Lancer was sucking on two of his fingers.

"You're the one who stirred me up this much," Lancer said confidently. "Reap what you sow Caster," he said, tearing a large hole in my long underwear.

"You animal," I grumbled.

But before I could make a move to swap our positions, the man above me shoved his partially lubricated fingers into my anus.

"As ucht De! Don't be so hasty you beast!" I exclaimed as pain ripped through my abdomen.

"You'll get used to it," Lancer decided for me, slowing down only a negligible amount.

As much as I had fooled around with Ferdiad, I had never done something like this before in my entire life. Not even close. I also couldn't recollect a master who was so domineering as to challenge my position in bed. Yet, I didn't feel anxious in the slightest. I was in my own hands after all. After a short while, I did indeed begin to feel nice.

That was until Lancers fingers slid across one particularly sensitive spot. A garbled, choking moan tore from my throat. My vision went blurry as my eyes crossed unexpectedly. Gasping, my mind barely recognized the experience as intense pleasure.

"Oh? Did that feel good?" Lancer asked rhetorically as he rubbed the spot again, harder than before.

This time my legs were left trembling and twitching out of my control. I don't even know if I had moaned or not. Draping an arm over my eyes, I hid my gaze from Lancer. Even in front of myself this was embarrassing.

"No wonder Ferdiad had wanted to do this to me. I make a very erotic picture in this state," I heard Lancer mutter.

Peeking out from under my elbow, I caught a glimpse of Lancer's penis. He was just as hard as before, a little bit of pre-ejaculate shining at the tip. "You had better find some proper lubricant before sticking that in me," I threatened. Although, my intimidation was reduced by the quiver I had in my voice.

"Say again? Did you want this inside of you?" Lancer asked, pretending to have heard me wrong.

"You heard me," I shot back, glaring into his smiling, red eyes.

"Why wait then?" he asked, spitting into his hand and rubbing himself.

"No, Lancer I'm s-"

I didn't get a chance to finish as Lancer shoved his dick inside of me. If I felt any semblance of pleasure, I didn't take notice. A terrible burning sensation overrode anything else. I growled in pain. Then I clobbered him, my fist bouncing off his temple.

"Cul Tona," I gritted out. Once Lancer had refocused on me, I gave him the sharpest glare I could muster. "Give me your hand," I demanded. Drawing a simple earth rune in the air, I summoned some seed oil. "Use this or I'm gonna knock your teeth in."

"Alright," he said, pulling out as tenderly as he could. "Sorry."

A little dejectedly, Lancer spread the oil across his genitals. Yet, dismay faded quickly as the oil warmed up and his hand brushed over his head. Growling, I grabbed the scruff of Lancers neck and pulled him into a toothy kiss. I bit into his lower lip, reminding him how much I hated being ignored. Having intended to give a playful nip, I was a little surprised when Lancer decided to enter me at that precise moment. Instead, I bit down hard, noticing the metallic taste of blood in my mouth. Now it was his turn to growl.

Pulling his lip from my teeth, Lancer spat blood across the room. "My, my. Does it feel that good Caster?" he asked, pulling out and slamming himself back into me.

I gasped and moaned, the nerves around my anus dancing in pleasure as I was stretched wondrously. I grinned up at him cheekily. "Your fingers were better."

"Tch," Lancer clicked his tongue.

He began to pound into me roughly, reminding me of how I had made love to the women in my past. The feeling was nice, but it was nothing compared to earlier. Slowly regaining my self-awareness, I watched Lancer above me. His face was screwed up in pleasure, eyebrows knitted together and jaw hanging loosely open. Then he decided to start playing with my dick.

"Lancer," I grunted, finding the added stimulus more distracting than exciting.

"What, you got to play with my spear earlier. Now it's my turn."

Annoyed, I reached forwards and shoved his hand away from my penis. Driving forward, I grasped his hips tightly; something that I knew would tip the power balance in my favor. With tight, warm pressure on each of his hip bones, Lancer reflexively slammed his pelvis into my ass, inadvertently brushing hard past that one bundle of nerves the man had found not long ago.

Howling with pleasure, my mind became overwhelmed by that intense feeling once again. It was all I could do to cling on to Lancer's hips.

"You sure change your tune fast," he huffed, grasping my shoulders to help keep me in that position.

He did not stop his assault on my ass. Humping quickly and firmly, Lancer rolled his sizeable penis around the unsuspecting bundle of nerves relentlessly. Each time he passed over whatever it was, some lewd and garbled sound tore from my throat. I even began drooling, saliva pooling in one of my ears. Between the barking coughs and moaning howls, I wasn't able to keep track of time passing. This felt better than even a trip to the Otherworld.

When the building ecstasy finally came to a head, my vision went completely white. Every fiber of my being shook like a reed in a stream. The mattress pressing into my back, my fingernails digging into Lancer's hips, Lancer's dick sliding up and down my rectum, all became infinitely more pronounced and unbelievably more stimulating. I will never admit to being surprised at how far my semen shot, erupting from the end of my penis like an exploding volcano. I was Cu Chulainn after all.

Lancer, for his part, never ceased in his pursuit of pleasure through the entire ordeal. For some time after I was sure that I was completely spent, he continued to fuck me like a maiden. The heightened sensitivity of my body and my quickly fading sense of reality caused me to lose track of how many times I orgasmed. For all I know I may have just experienced one very long orgasm where fluids did not cease to drip and shoot out of me.

When he was finally done, Lancer pulled swiftly out of me. He sounded refreshed, stretching out his legs and cracking his neck. I remained exactly where I had collapsed, although I don't remember doing so. Still reeling from the most fantastic sexual experience I had ever had in my life, I allowed my body to melt into the mattress. Sweat, tears and saliva were all dripping from my face and my body was practically vibrating I was so shaky.

Eventually, the light behind my lazily drooped eyelids began to cause my some annoyance. Still covered in ejaculate, I rolled unapologetically over and buried my face in one of the pillows.

"Hey," Lancer wined. "Caster, that's gross."

"I'm tired," I mumbled back, muffled by the wonderfully plush pillow.

"Quit your bitchin and get up. At least go take a shower or something."

At the poorly concealed dog insult, I grabbed the other pillow and tossed it in the direction of his voice. This, I did not quite manage to accomplish. My limbs had an inexplicable weakness, so the pillow missed the target and landed on me instead.

"At least go sleep in your own room." Lancer sounded exasperated.

Technically, Lancer and I were the same person, so technically this was my room. I had no intention of getting up. The call of sleep was far too enticing. None of this, I bothered to tell my other self, as I drifted off into a welcome slumber.

Meanwhile, Berserker was relaxing after winding down from his own day. Idly, his thoughts began to stray towards his other selves. He wondered if their minds worked in the same way his did, and if they too had been having the same thoughts as he. Before his gaze a white, slimy substance stretched between his clawed fingers. Rubbing his fingers together, Berserker brought his hand to his nose. With a curious sniff, he licked slowly along the length of his finger.

No, he decided, those three were defiantly not thinking the same thing he was. But he would find a way to make them.
