I pulled up in the gas station. Some soldiers needed a break from the ten hour drive. I parked next Optimus and cut off my engine. I am also in desperate need of a break. The mission itself went perfectly fine, but the drive back was long and tiring. I activated my holoform and hopped out. I am going to buy some food. Nothing is better than I good midnight snack. I shut my door. 'We are leaving in ten minutes.' I turned to face Prime. 'Si, I won't make it long,' I assured. He nodded. 'You need anything?' I asked. He shook his head. 'No, I am good.' I turned around and strolled into the shop. I got myself some soda and a muffin.

I sat down on my hood. 'What?' I asked, glancing at Prime. He was leaning against his truck, watching me. 'Nothing,' he shook his head. Prime is always surounded by Prowl, Ironhide or Ratchet. People barely get the change to talk to him alone. He used to interact a lot with other bots as well and now I barely saw him. 'I barely get to talk to you,' I trailed off,– getting his attention again. 'What would you like to talk about then?' he asked. I leaned against my windshield. 'I don't know... stuff. Something that's not work related,' I said before taking a bite. He watched me. 'Don't judge my muffin,' I added. 'I won't.' I turned my head. 'You're so stressed lately. That's not a good thing.'

'I appreciate your concerns, but don't worry. I am fine.' I nodded again. 'You know that as a spy, my senses are ten times better...' I trailed off. He gave me a look. 'Just saying that your heat is approaching.' He had a more strict look in his eyes. 'Okay, I'll shut up...' He nodded. 'Thank you.' I smirked a little before taking a bite. 'So is yours...' he said after a long silence. I looked at him again. 'A couple of months, yours maybe a few weeks,' I said. 'Well, then you know Prowl will take over most of my duties until it faded a little.' I shrugged, 'it's nothing to be ashamed about. Heat cycles cause mechs and femmes to be cranky all day. I mean... I am really cranky and frustrated all day.' He shook his head. 'Sometimes I forget about your good senses. Only Ratchet is able to tell me that type of thing.'

'Does is annoy you?'

'No, usually my mechs don't annoy me that fast,' he said. 'But because you're my commander, you don't like it. You rather keep it private and I get that.' He nodded. I looked at some bickering soldiers and shook my heads. 'Humans can be stupid,' I muttered. 'Some of them.' I snickered and ate the last piece of my muffin. 'You did good today.' Surprised I looked at my right again. 'Thank you, sir.' He opened the door of his truck and climbed back in. We hit the road a few minutes later and I drove right behind Optimus. Usually Prowl drives there, but I had claimed the spot to Prowl's annoyance.

Back at the base, Prowl followed me and blocked my way. He's pissed. 'Don't ever pull a stunt like that again or next time you can rot for two days in the brig. Am I clear?' I gave a small nod and lowered my doorwings. 'Stand down, Prowl.' I perked my helm up as Optimus approached. 'Leave him be. He did nothing wrong. He just wanted to drive behind me and nothing is wrong with that. We never set rules for where we drive,' he said and passed. I smiled a little as I watched Prime, but it faded as I saw Prowl's face. 'I am gonna go. Clean myself and get some rechage,' I said, stepping back. 'You stupid spy,' he snapped. I said nothing and walked off to the wash racks. I started to take off my armor so I could get the sand and dirt out. Usually, I never take off my armor, but it's late and I didn't expect anyone.

I closed my optics and let the warm water drip down my frame. 'You're alright, Mirage?' I jumped and turned around. 'What–, y-yeah...' Optimus studied me for a moment. 'You seem upset. Is it about what Prowl said?' he asked. 'No, it's fine. Don't worry about it.' I waved it off. Prime approached and got so close I could feel his body heat on my frame. I felt uncomfortable and embarrassed at this point. I was naked and I didn't like showing my protoform to people. 'Don't listen to him. You are right, I stopped interacting with the other mechs and femmes. I am busy and I know you like talking to me.' I shrugged. 'I get it, you're busy. Not your fault,' I sulked.

'Can I make it up to you?'

I was caught off guard by his question. 'Sir?' His servo's grabbed my hips and pushed me against the shower stall. My cooling vents kicked in instantly. 'I am still dealing with that approaching heat. Maybe you'd like to help me with that?' he asked. I was speechless and only able to nod. The tall mech buried his faceplates in my neck and started to kiss and suck. His servo's rubbed over my chest, scrubbing some dirt off. Moans escaped from my throat.

He lowered his face and caught me in a passionated kiss. This was not what I expected to happen tonight. The mech pinned my arms above my helm. After a few minutes, he pulled back and his servo's traveled towards my thighs. O groaned and threw my head against the wall. 'I never imaged your would make so much noise, Mirage.' I blushed madly. 'I thought you would be the silent type.'

'Just really tense lately.' He hummed and buried his faceplates in my neck again. His digits rotated over the only piece of armor that was still on. My codpiece and slid out of the way by an instant as I felt my spike press against the cover. I groaned as he pushed two digits in my valve and arched my back. His interface panel slid back as well, revealing his hardened spike. He turned me around, pushing me tightly against the wall and slapped my aft. I uttered a long, needy moan. He slowly pushed in without a warning. He only gave me a few seconds to adjust before he started to move.

My entire system was heating up. The mech grabbed my doorwing, massaging them. It felt ten times better than I imagined. I held onto the wall. 'P-please...' I whimpered, I needed him to go faster. Optimus stopped and pulled out, turning me around. He grabbed my thigh and threw it over his hip. His lips connected with mine again. I felt my overload approaching fast. It was nearly embarrassing how quickly my overload was approaching. I don't think Prime was anywhere close to overloading. 'I- I...' I tried to form the right words but nothing came out of my mouth.

I uttered a long moan,— my walls clenched around his spike. 'Already?' I blushed. Prime smirked a little. 'Was I hitting the right spots?' He cooed near my audio. He changed into a whole different mech. He didn't stop and continued. 'Keep it up next time.' I nodded, although, I wasn't sure how I am able to manage that. After a few minutes, his thrust became sloppier and he came, so did I for a second time and cried out his name.
