Three months and a half in the past

This was the fifth time that Arcee had snuck out to meet up with Starscream in the middle of the night, this time Arcee was lucky and ratchet went off to bed early and she sent a message to Starscream around 12:30am and she drove out to meet him at the place as per usual. But when Arcee transformed to leave she felt different somehow, like there was something in her that prevented her from wanting to change but she ignored it and traveled the distance from the base to Starscream.
Once she got there she found Starscream leaning against the rock that she had gotten to know very well and kissed each other to say hello and went for a walk to a cliff side and they laid down to gaze up at the crystal littered sky.
It were moments like these where they completely forgot about the war and their darkened home world, both Arcee and Starscream were taking every risk that they could get just be together, he has suggested eloping before but the femme said no because she would loose her family and betray her junior partner Jack. The ex-con didn't want to make her upset and so they decided to stay where they were.

Arcee sighed deeply as she snuggled closer onto his chassis, rubbing her digits around his insignia, he purred at the sensation and nuzzled his helm on top of hers while pulling her in closer to him by her waist, both enjoying the warmth of each others frames. Through the bond they shared the could feel their love for one another and she had noticed that he has been a bit quiet for a while now and she looked up at him.
"Hey star?" She whispered and he drew his attention away from the sky and looked down at her, the femme sat up on her forearms staring into his ruby gentle optics. "Are you feelin' ok, you seem quiet"
"Well today when I was working in the lap with the red energon and I accidentally mixed the wrong chemicals together and I got a nasty gash on my left cheek plate from explosion" he explained and showed his cheek to her. Arcee's optics widen as she saw his cheek corroded slightly with melted metal but it wasn't serious, she sat up fully and cupped her right servo around his face then leaned in close to inspect the damage that she hadn't noticed before.
"Oh Hun are going to be ok?" She had a worried look and he hummed in response until suddenly he grabbed her hips and slid her over his waist, she instinctively put her legs on either side of him, she looked down at him with a blushed angry expression with her arms closed over her chest. He chuckled and laid his servos on her hips with a sly grin, "your such an afthole, did you lie to me just so that I have to be on top this time" she asked with a smirky smile
"Maybe, but you are so cute when you worry like that and I couldn't resist"
"Well then, next time if you get stuck in your lab with a giant fire breathing dragon, I'm not saving your burnt backside" she said as she looked away with a smile.
He cocked an optic ridge and at the mention of the dragon and asked.
"What's a dragon?"
"It's a giant fire breathing lizard with wings" she said and leaned in to peck him on the lips, the kiss soon turned into a heated frenzy and he rubbed his servos along her back struts then she moaned in his intake at the touch, Arcee slid her servos up and down his chest, within her processor all she wanted to do was to kiss him endlessly but that wouldn't satisfy her growing need.
Arcee could tell that the silver mech wanted the same and both cybertronians knew what to do next as he pulled her upwards in better position just above his crotch area so he could lean up against a rock, her heat scraped along his port making them both moan at the same time. Arcee giggled and leaned in over him to kiss him deeply while closing their optics, both bot and con moaned again as pleasure was slowly growing inside their glowing sparks and then without saying a word Arcee laced her digits over his crotch piece and giving it a quick massage, he responded bashfully by removing his plating to let out his aroused member. She too then removed her lower region armour and caressed his metallic spike, her wet valve touched his mech hood in all the right places that made him roll his optics back in a glazed over way to say that he wanted her more than anything in the universe as he held on tightly to her hips.

The femme the adjusted her hips directly above the tip and she used her servos to properly ready his shaft to her slick entrance and then without warning she dropped her waist down onto his, they both cried out in pleasure.
"Ahh ahhh~" acree curled her body inward while gripping tightly onto his huge shoulders for support, the thick hardness inside her twitched with anticipation and excitement.
He breathed heavily with a huge smile on his features and he looked up at her, "*sigh* oh Arcee my love, your so impatient"
"I just can't help myself anymore, I love you much" she answered with a slightly cracked vocals, as if she was on the verge of tears for some odd reason even though they done a couple of times before.
They kissed again and pulled away from each other to look down at their sexual connection and then without an other word between them she began to slowly bounce her hips up and down with her optics closed to focus on the inner pleasure and action. Vocal moans escaped from their intakes and reached their audios, her moans were like a song of symphony to him and he grew more aroused to meet her bouncing motions with his own thrusting hips up into her thighs.
Her pace became faster by the second as intense pleasure consumed both autobot and ex-decepticon as they join together as one, their inter-cause will probably  last until morning just like two predacons in heat.
As the night went on Arcee's inner leg circuits were beginning to hurt badly and she wrapped her arms around his neck to bring him closer to her chest as his spike was rubbing painfully and sweetly against her g-spot and he wrapped his left arm around her back and his right servo gently held the back of her helm, Starscream moaned seductively while kissing her sensitive neck cables to encourage her to keep going.
The ex-con could sense both of their overloads approaching and she made her movements slower to catch her breath for a minute before bouncing faster with sloppier timing to meet his thrusts.
"Ah ahh ah s-Starscream I-I'm so close!" Arcee shorted her grinding on his spike with harder and rougher bounces as her processor was going fuzzy. To Starscream his numeral net was trying to make him comprehend the pleasure she was giving,even though he enjoyed watching this side of her loosing control while fragging him raw, there was something very different about her body language and shape as he looked down to her lower stomach and saw a small bulge forming and he thought that maybe he was fragging her to point where she was bending out of shape. But her emotional state was worrying him the most as he saw her optics that were more brighter, doeyier and desperate but before he could think any further he felt the knot within his stomach snap and he grunted out while holding her tightly in his arms.
"Grr ah ah I-I'm coming babe!!" Just on time his spike flared up and warm trans fluid liquid exploded inside her already occupied womb, a few seconds afterward Arcee came as well as her valve clamped around his spike, her vision turning white and a silent scream erupted from her throat. He too saw the same thing as entire frames shook violently and finally when he was fully drained he slipped off the rock he was leaning on and flattened his wings and back on the ground with Arcee laying on top of him, their sparks beating rapidly in unison through their bond and they fell unconscious.

They took a quick thirty minute nap in the same position until he snapped his optics awake and rubbed them then soon after he woke up Arcee to make sure that she went home before it was too late or early in the night after when he checked his internal clock to see that it was 3:45pm. Once they were fully awake they went to get washed off in a shallow river nearby the couple then kissed each other for a final goodbye and he transformed and left back to the harbinger.
Just before Arcee transformed into her alt mode she felt the feeling from before in the base, she then ran her digits over her stomach and felt the bulge but she ignored it and thought that being sexually active will have its consciouses and this is price. She then transformed and drove drive back to base.

After two weeks had passed sense that night, she got the realisation smacked in her face about how she was pregnant and told Starscream the next day, and now everything is up to date with the back stories.
