Today was a sunny day. You arrive at the base in Bulkhead vehicle mode. Since Optimus was out on a mission by the time school ended, you ended up riding with Miko and Bulkhead. You didn't mind. You love the two hard-headed friends and hanging out with them. Which you all did after school, going off-roading on the big rocky hills.
You jumped out of Bulkhead, and Miko did the same. Bulkhead immediately transformed into his normal form. He grunted and opened his chest, where he pulled out Miko's guitar. Miko laughed and grabbed the guitar from his hand. You started walking up the stairs to the second floor, where we usually hang out.
"Hey, is that a sweater you're wearing? I don't remember seeing you with that sweater on today." Miko asked, running up to me.
You stopped as you reached the second floor and looked back at Miko in confusion. You looked down at the sweater you were wearing and remembered what she was referring to. "Oh yeah, I borrowed it from a classmate. I got cold in the class and he lent me it. I guess I forgot to give it back. it's really soft and comfy. It's a nice quality, too." I held the sweater out to her. Miko touched and was surprised by how soft it is.
"Wow, it is really soft and it's really warm. You need to ask him where he got it because it will be so good for the winter. Not only that, it's such a pretty color," Miko said, admiring it.
You rubbed the back of your head. "Yeah. It really is. It got really warm once I wore it for a little bit."
Miko suddenly stop and stare at the sweater. You stare at Miko in confusion until she took a sniff of the sweater.
"And it smells really good, like really good. I'm used to guys' clothes smelling horrible, but this one smells really good. If he uses a cologne like this, he must be a hottie." Miko got excited. Miko started to ask a bunch of questions about who this good-smelling guy is.
You blushed and tried to stop Miko from asking all these questions. Then, you saw Optimus walk into the lobby. You got excited and immediately got his attention. When Optimus saw you, he smiled and walked up to you.
"Greeting Y/n, how was your day at school?" Optimus asked. He put his hand on the railing beside where you were.
You smile happily. "It was great. The teachers didn't give me too much schoolwork, so I was able to finish them before I left from school. How was your day Optimus? How did the mission go?"
Optimus began telling you how he day was and the mission going smoothly. Until he slowly stop talk as he gave you a strange looked. You looked up at him in confusion. You ask if he was okay. Optimus stayed silent and kept looking at you. You started to get worried and ask if he was okay again. He suddenly pick you up on his servo and started walking to the hallway.
You were confused on what was happening and worried about Optimus sudden quietness. You realize that he was taking you to his private quarters. He open the door and walk inside. He close the door behind him, locking it. He walk to the berth and settle you down gently on it. You looked up at Optimus, confuse on what was going on. and why he was acting like this. He mass-displace right next you. He had a look that you never saw before.
He walks towards you and grabs hold of you. You squeeze your eyes shut, waiting for the worst, but nothing comes. You felt Optimus fiddling with the hem of the sweater you were wearing. You open your eyes and look down to see Optimus pulling on it slightly. You looked back at Optimus and asked what was wrong.
"Who is this? I don't remember you having this sweater," Optimus said sternly. He kept tugging it like he wanted to take it off you or rip it off you.
"It's a classmate of mine. He lent it to me because I got cold in class. I forgot to give it back to him at the end of class," you explain to Optimus.
Optimus looked unsatisfied with the answer you gave him. "Why?" He looked at you with a look that you didn't know how to reply to.
"W-Well...I don't know. i guess he was being nice and he offer so I took it."
Optimus hum. He kept tugging at the hem of the sweater. You felt like he was going to tear it.
"Take it off." Optimus said, with venom in his voice.
You flinched at his voice. You took off the sweater without hesitation, worried he would get mad even more. Optimus snatches the sweater from your hands. You tried to get it back.
"Optimus give it back. Please don't rip it or damage it, I have to give it back." You jumped up trying to get it from Optimus grasp as he held it up high.
"Why do you care if it gets damage? It is just a sweater," Optimus said coldly.
You puffed at your cheeks. "Because I have to give it back to him, and I don't want to buy him a sweater to replace the one that you damaged." You kept jumping, trying to get it.
Optimus still kept it high so you couldn't get it. He stayed silent, thinking. He took a step away from you and threw the sweater away from you both. You gasp at what he did. You tried to go retrieve it, but Optimus grab you and held you tightly. His head in the side of you neck.
You froze. You tried to look down to see his face, but he kept it hidden in your neck. The two of you stood there in silence. You were about to say something until Optimus took a deep breath on your neck, smelling you. He growled lowly after he did so. Then, he started to undress you. You panicked and tried to stop.
"W-What are you doing Optimus? Are you out of you mind?" You yelled at him.
He quickly looked up at you with anger and jealousy. "Are you out of your mind. Why did you put on another man's scent on you?"
You were taken aback by what Optimus said. You wanted to say something, but the words were stuck at the back of your throat. You kept opening your mouth and closing it.
Optimus didn't wait for your response and kept undressing you. Taking off your shirt and your bra and grabbing your tit harshly. You yelped at this action. You grab his wrist to stop him from grabbing your tit so harshly. You were about to yell at him, but he crashed his lips against yours. He then pinches your nipple, and you moan into the kiss.
His other hand was behind your back and pressing you into him. You begin to kiss him back as he played with your nipples. You moan and yelp every time he twists and pinches your nipple
He broke the kiss and began kissing down your neck. Your jaw, underneath your jaw, the side of your neck, and lastly, your scent gland. He growled when he did. He bit down on your scent gland, which made you yelp. It wasn't hard enough to draw blood, but hard enough to see the bite mark.
You tried to push him off, but his hand went up your skirt and into your underwear. You gasp as he palms you. Lifting and grinding his digits against your heat. You moan at this motion. You grip his shoulder as he palms your heat roughly. You start to grind against his digits.
Optimus continues to kiss your neck, giving you hickeys all over, making them a dark purple. He slowly brings you down to your back. As your back hit the cold concrete, his digits went inside your hit and start to finger fuck you. You arch your back and grab his arm for support. You moan loudly as he hits your G-spot. Tears prick the corners of your eyes.
Optimus ignore you and kept fucking you. You start to grind with his finger, trying to reach your climax. Optimus watches you arch your back even more, and your head falls back against the concrete. He could still smell the guy's scent all over you. It's flooding all his senses, and it starts to make him go mad.
You were about to cum until he remove his digits from your heat. You whined as he did so. Optimus then put his digits to his mouth and licked them clean, savoring the taste of you.
After he was done, he grabbed your hips and aligned them to his panel. He lifted up your skirt and ripped your underwear off. You could he the fabric rip from your body. He then opened his panel and his spike came out. His spike was already leaking and twitching. You drool at the sight of it.
He starts to grind his spike against your heat that is covered in your wetness. "I'm going to fuck the scent off you," Optimus growl.
Your eyes widen at what he said. Optimus then sunk his spike into your pussy. You moan as he fills you up, stretching and hitting every sweet spot that you didn't even know you had. Optimus gave you time to adjust to his spike, but started to grind at your G-spot. Then, he started to fuck you hard and sensibly. You held onto Optimus' hands that were on your hip dips, holding on for dear life.
Optimus fuck you hard and roughly. The ridges on his spike rubbing up your wall so roughly made you drool and cry out his name.
"O-Optimus. S-slow down. Its too deep."
Optimus kept fucking you, using you as a flesh light. He adjusted himself and starting fucking you right at your g-spot. You moan loudly and throw your head back. You start to grind your hips upwards against his hips to get closer to your climax.
Optimus' hands tighten on your hips, so that you know for sure they would bruise. Optimus picked up the pace and fucks you harder than before. You came hard on his spike. Your walls tighten hard on Optimus spike. He stopped and pulled out.
He then flips you over to your belly and lifts up your hips. Your sex is exposed to the cold air. He then pushes his spike into your heat all of a sudden. You moan loudly, feeling full again. Optimus uses his hand to push on your back to make you arch. The other hand pushed your head against the floor.
Optimus begin to fuck you, overstimulating you. His hands keeping you in place as he abuse your pussy. You moan against the concrete. The tears starting to fall as he fucks you hard. You could feel another climax coming in fast.
Optimus felt your walls tightening up against his spike. He begin to fuck you harder and pushing his spike deeper in you. Optimus leaned down to where his face was up against the side of your neck. He moved the hand that was on your back to your hip so he could pull you back into him as he thrust into you. The other hand, supporting himself so he doesn't put all his weight on you.
Optimus spike hits aggressively against your G-spot, and you start to see stars. You bit your lip as you felt each thrust rubbing against your walls. You cried out as you came hard on his spike. Your walls tighten and pulse against his spike.
Optimus groan, feeling you cum a second time. Optimus's hips start to buck wildly into you. Optimus moans loudly against your neck and bites hard on the side of your neck. Optimus overload, painting your insides blue. His hips kept thrusting into you, trying to calm his high. He lets go of your neck and leans his head against the back of your neck. He breathes heavily.
After a while, he slowly lifted himself. He cranes his head down to see his transfluid spill out of you. It drips down your thighs and drips on the floor. Your hips fell to the side as you breathed heavily, still in a sex daze.
Optimus pulled you against him and hugged you. He kissed your forehead, your temple, and your lips.
"Are you alright? You're not hurt, are you?"
You looked up at Optimus in a daze. He looked at you worried. He moved the hair out of your face.
"Beside the bite mark, no, I'm not hurt," you said weakly.
Optimus looked guilty. "I am sorry for biting you. Did it hurt when I bit you? I am also sorry for being so rough on you."
You gave him a smile. "No. You should be rougher on me like this." I giggled stupidly.
Optimus sighed and smiled at him. He kissed me softly and lovingly. You kissed back. Optimus' hand went up at the back of your neck to deepen the kiss. You let him.
Optimus broke the kiss and looked serious. "I do not want to find another man's scent on you again. If I do, I will do the same thing I did just now."
You blushed, but turned into a smirk. "Then I have to do it again, if you get to fuck me like you did just now." I giggled.
Optimus gave a tired sigh, then smiled at me. "If you do, then I may have to not let you cum for your punishment."
You froze. "You know what. I'm not going to do that then."
Optimus chuckled and put his face against my scent gland. He smelled heavily against it. He sighs into my neck and snuzzles against it.
"All that matters is that your scent is not flooded by his scent."
Optimus hugged me tightly. You put your arms around his neck and nuzzle against him, tiredness overflowing you.
"I'm glad. I want to be covered by your scent."
Optimus smiled. "Good. I've made sure of that."
