"A what?" I asked Optimus.

"A Pod, we found a pod containing some life form – we suspect it's another Autobot; however we cannot be sure. Ratchet is taking it apart and fixing its internal programming as we speak." Optimus responded.

When the Autobots returned to the base, they brought with them some large oval metallic object; I had no idea what it was. I waited until Optimus and Ratchet settled in, both had discussed the pod with Lennox and his superiors for an hour or so. Once Optimus left, I caught up with him and asked him what had happened. He picked me up and carried me out away from the base so we could spend some time together – once we were alone he said he would explain everything to me. He had carried me a good few hundred meters from the base, under some trees to keep the setting sun from hitting me in the face. He sat himself down, carefully leaning against one of the trees and then began to explain what had happened on his mission. By the time he finished explaining everything, the sun had set and the starry sky shone above us.

"I admit I am a bit disappointed in the fact that no Decepticons were captured. I had hoped to put an end to one of them today." Optimus sighed.

"Well I for one am glad you didn't run into any of them, that way I don't have to worry about you getting injured – or worse." I shuddered at the thought.

Optimus, sensing my anxiety, rubbed a careful thumb along my back, and immediately all of my fears were soothed.

"You have nothing to fear my love." Optimus consoled me. "I am not going anywhere."

"I know you wouldn't go anywhere by choice – but I can't help but think back to that time – " I felt another shiver run through me.

Optimus held a hand up to stop me, "Please Delyia, do not think of that any longer. It is not healthy to dwell on such things for long periods of time." Optimus's optics held a far off look, not like when he searched for things, but as if he were remembering something long past.

I cocked my head to the side and rubbed his hand,

"Are you okay? Is there something bothering you?"

Optimus shook his head,

"I must be honest with you – since I've returned I haven't been able to get your face out of my processor's memory. The last look I saw before – well you know what happened – it has haunted my offline mode since I returned here."

Shocked, I couldn't think of anything to say. What can you say?

"I do not mean to make you feel uncomfortable Delyia. I only wished to share – "

"Optimus you could never make me feel uncomfortable. I just – I don't know what to say. The only thing I can think of is that eventually you'll decide to not let this affect you anymore, and on that day, the nightmares will cease to exist. I'm sorry that this is haunting you. I don't want you under any more stress than needed." I felt a deep resounding sorrow for him, how can he handle all of this and remain this beautiful being I see before me?

"Delyia, I truly care for you, and I thank for you consoling me. Hearing you speak those words has given me a relief and pushed me towards the direction I think I need to head in. However, I do not wish to spend all night speaking of undesirable topics." Optimus hummed, "I would like to say that the other day, when we shared your human customs, I was very intrigued."

A blush rose to my cheeks as I thought that to that night.

"Why intrigued?" I asked him, almost nervous to finding out the answer.

"Well, we had something similar on Cybertron but not to the extent that you humans have come up with. Is it customary for human couples to share lips often?" Optimus asked.

I nearly laughed at the term, 'Shared lips' it sounded so silly to hear that phrase.

"Well yes, human couples express their love and affection for one another through the act of kissing, and couples who have been together for a longer period of time, often go even further than that."

"Ah yes, I believe you're talking about your mating rituals." Optimus responded.

Rouge enflamed my neck as I nodded; I can't believe he said mating rituals.

"So, how does a human couple mate?" Optimus asked, I felt a rush of adrenaline burn through me.

"U-uh well, it's kind of hard to explain I – "

Optimus's optics distanced for a few minutes. I felt the red burn even brighter, as I waited for him to say something. Are we really talking about sex?

"Hm I see." He finally spoke up. "Your rituals are certainly different than on Cybertron."

"How so?" I asked, relieved to have the pressure of explaining off of me.

"Well, when two 'bots are mating, we offer up our sparks to one another. It is a very intimate gesture, and often takes about three earth hours to complete. Our sparks would collide and mesh together, leaving bits of each behind with the other. It's a very intense and electrifying experience for a bot to undergo. Not to mention it's very sacred between the two – it's the ultimate way to show affection for another." Optimus concluded.

I raised a brow and looked at his glowing chamber. I wonder what it looks like.

"Do you think I could see your spark?" I asked.

I heard Optimus cycle in massive amounts of cool air, and I looked up at his optics to make sure I hadn't said anything wrong. Optimus's blue eyes were wide and his mouth hung ajar for a moment. Suddenly, I got the feeling I did say something out of turn.

"O-Optimus I'm sorry I didn't mean to offend y-"

"No no, Delyia you did not offend me. You merely caught me off guard. Revealing one's spark is something that is not often done, and if it does occur it's with someone that a bot has a very intense connection with. It would be somewhat the equivalence of a human showing another human their naked bodies." Optimus explained.

"I understand. Optimus, I am sorry. If you don't want to show me, that's totally understandable. I didn't realize how intimate that was." I stuttered out.

A few moments of silence passed before he responded to me. He looked down and all around me lit up a brilliant blue hue. I glanced up at his bright optics and saw his metallic lips upturned.

"Delyia, I believe that there is something strong between the two of us. 'Bots do not fall into connections with others lightly. I feel whole with you, my sweetspark; and I want you to see all of me. So," he brought me close to his spark chamber.

(ATTENTION: Mature Content!)

The closer I got, the more I could hear the thrumming of his spark against his chassis. I could feel the heat radiating from his spark as his body shifted and whirred, opening up the chamber. Once all protection had moved away, I felt an immense heat radiating from a cyan blue sphere. It shone with such ferocity that I had to look away for a moment. This was Optimus, the true Optimus Prime. As I stood, entranced by the heat and light, I began to feel like a moth to a flame. I was drawn in to him; I needed to be as close to him as possible, to feel the electricity against my skin. My breath hitched as I hesitantly reached out to him, the sparks shot up my arm giving me a burst of adrenaline. I glanced up at Optimus with tears pricking the corners of my eyes,

"You are so magnificent." I gasped.

I heard his spark thrum even louder at my statement, which drew my eyes back in. In this trance-like state I reached out again, this time gently grazing the brilliant sphere of light. I felt its energy surge through me again, and it electrified my body in the most exciting way possible. I felt a shudder rumble through Optimus and I looked up to him in shock. His optics had closed and his head rested against the tree behind him. Does this feel good to him? My brow knitted together in confusion. Might as well try it out again and see if I get the same reaction. I watched his expression as I reached out again and lightly massaged his spark. Almost immediately, I heard a rumble thunder through his body. I couldn't explain the sound no matter how hard I tried, but whatever it was – it excited me. I felt my heartbeat quicken as the ethereal sound emitted from Optimus's vocal processor.

The adrenaline pulsed through my legs as I continued to gently knead his spark. The beautiful blue sphere was a little malleable, and it somewhat formed and shaped with whichever way I moved it. It was as if it were just a ball of energy, moving and flowing with the wind. I felt a tremble rush through him as I gripped his spark with a tense hand; his other hand dug into the earth beneath him. His facial expression tightened as I continued to manipulate his energy. The thrumming pulsed faster as the motions of my hands did. A sound erupted from his mouth, a string of sounds that I had never heard. It almost sounded like Latin but, there was a ring to it that I couldn't quite place. Whatever Optimus was doing, I fell in love with it. The sounds that escaped him I wanted to hear over and over. I felt the need build up within my lower region and I picked up the pace, only wanting to experience his sounds. As time went on I realized it must be Cybertronian, I couldn't pick up anything that resembled any language I had ever heard. I decided in the back of my mind that I'd want him to teach me some Cybertronian if he could some day. The string of sounds increased as I felt the trembling double, I almost fell off of his hand once or twice. My own need strengthened as I continued to massage and rub his energy source. Finally, after God only know how long, his bliss erupted and sent shockwaves through my arms and to my heart. I felt my heartbeat stop for a moment, and restart with vengeance as Optimus let out a cry, shouting something in Cybertronian. My body felt like it was on cloud nine, lighter than a feather as it was surging with so much energy. What just happened?

(ATTENTION: Mature Content Over with)

I heard Optimus begin to cycle in air as I sat in his hand, trying to catch my breath. Once he recovered he opened his crystal blue optics and looked at me.

"Sweetspark what did you do to me?" he asked.

I shrugged, shivering from the amount of excitement running through me.

"I don't know but you seemed to be enjoying it so I didn't want to stop." I sheepishly rubbed the back of my head.

His spark retreated back into its layers of protection and he brought me close to his face. I hugged his cheek and planted a small kiss there as well.

"Whatever it was, I have never experienced a sensation such as that before. It was quite enjoyable – I don't know how to explain it to you. I believe the equivalence would've been, possibly, mating with a sparkmate. The intensity that surged through me, it was almost unbearable." Optimus explained, his eyes on the sky.

"So you did enjoy it?"

Optimus nodded, a small smile stretched across his face.

"Yes my love, I enjoyed it thoroughly."

I giggled, slightly embarrassed and proud of my accomplishment.

"I enjoyed watching your expressions, and the sound you made – it entranced me. What was that anyway – were you speaking in Cybertronian?" I asked him.

"Well, I can't remember much of what I was saying, but most likely. Did it sound like this –" and in that moment those beautiful sounds echoed from his lips again, resounding through my body down to my very cells. I couldn't get enough of that even if I tried.

"Yes it did, oh Optimus it sounds so beautiful. What did you say?"

"The earth equivalence, this is a rough translation, would be I love you my sweetspark."

My eyes widened as I heard those words whisper through his lips. I love you. He said those three words, and I instantly felt the amount of love I held for him double.

"I-I love you too Optimus." I stumbled through the words; the feeling of them on my lips almost scared me.

Almost.

I felt a yawn escape my lips as I stretched and hugged his hand.

"Thank you Optimus."

"For what?" he asked me.

"For loving me." I responded, cuddling against his hand.

I felt him cycle out air and slowly stand up.

"It is I who should be thanking you my beautiful Delyia. You have truly shone a light of true ethereal bliss onto me ever since you glided into my crazy cycle."

My heart leapt at his words and I only wanted to lay here with him forever. A few moments of silence passed between us, and I felt a heat between my legs return. Surprised I thought about why all of a sudden it would come back. Before I could think for too long Optimus turned and began to walk back to base.

"It's getting late and you need your rest my little one." Optimus explained as he approached the base.

Once we reached the hangar he set me down and transformed into his alt-mode. His beautiful Peterbilt truck rumbled off into its corner of the hangar, and out stepped his holoform in all his glory. As he approached me I felt the heat in my abdomen intensify, and my knees began to shake with energy. I must still be reeling from earlier. I thought as he stopped right before me.

"May I walk you to your room my love?" Optimus asked, holding out his hand.

I took it, his hand warming my own, and allowed him to lead me back to my room. The walk there was spent in a blissful silence, my mind racing miles per second. I stole a few glances at Optimus's holoform: his strong jaw, light stubble, and dark eyes only intensified the need within me. Control yourself Delyia. I chastised myself as we approached my door. I turned the knob and looked back at Optimus, his eyes lit up with a fire I hadn't seen before.

"Delyia," He whispered my name as he closed the space between our bodies.

His hands found their way to my cheeks, holding my face mere inches away from his own. I could smell his scent, heavy on the holoform's clothing.

"Delyia, you have given me an experience I had not shared with anyone else in my lifetime. You satisfied a need I did not know I had, and I wish to return the favor." He huskily whispered to me.

I found that I had lost my will to speak as his lips crashed down onto my own, stoking the fire deep within my body. He removed himself from me, and his eyes seemed to pierce my soul as he asked me,

"Would you wish for me to – "

"Yes." I interrupted him, hungrily grabbing him and leading him into my room.
