Summary: "The one name you can call out tonight is mine, got it, Lizard?" He smirked before forcing his helm forward, slamming his lips against hers once more before pulling away. "Whatever you say, Lady Bug."

Author's Note: Wow, I wrote this super quick. I have finals this week and finally took a break from studying to write this up lickity-split, hehe. I actually can't believe how fast I wrote this, considering I just finished writing my English final. Perhaps my muse is beginning to cooperate for the time being, eheh. And whoops, looks like I got carried away again. Oh well, hehe. Anyways, this was a request from SpeedStreek360, who is a wonderful author and is one of my favorites. Although, to get this pairing, you might want to read her story "Take My Spark" and before reading that, read "Three Little Words". You won't regret, I assure you that!

I hope this is what you were looking for, Speedy! I had a lot of a fun writing this, and if you've got more you'd like to see, send me a message and I'll see what I can do! Alright, enjoy!

Bang Bang

"You. Me. Berth. Now."

Grimlock was shoved into his private quarters and was pushed down onto his berth while soft lips assaulted his own. His mouth was invaded by his lover's glossa, and he relished in her sweet taste. Her servos run up and down the front of his chassis while he let his own wander, moving with the grooves of her own body.

One servo slid down her back while the other moved to her front, suddenly groping her aft and bust. She gasped, her glossa slipping from his mouth, a trail of oral lubricant connecting them. She growled playfully before nipping at his lips.

Primus, he loved an assertive femme.

"Now if you can't behave–"

Shrapnel gasped again as Grimlock slapped his servo against her aft, the sound resonating off the walls of his quarters. She snarled before wrestling him in the berth, reaching up to grab his wrists, shoving her large bust into his face.

Grimlock took this opportunity to lick at her breasts, causing Shrapnel to groan as she continued to work. The Dinobot didn't stop until he heard a faint click, and his optics opened wide behind his visor as his lover pulled away. He tried to pull his arms down, but found that they stated firmly in place above his head. His visor grew bright as he turned to glare at the Insecticon.

"Hey! That's not fa–"

He stopped when he felt soft digits press against his lips. He say her smirking at him, and his cheeks quickly gained color, both from arousal and embarrassment.

"Now, Grimmy. I told you that if you didn't behave, I'd have to make you."

The Dinobot leader gasped loudly and groaned when Shrapnel began to grind her hips against his heated pelvic plating. He panted as she teased sensitive areas on his chassis, her digits slipping underneath plating and playing with the wires that sent shocks of delicious electricity coursing through his frame.

"Oh, Primus–"

Grimlock cried out in pleasure and pain as Shrapnel slammed her hips down against his plating, his pressurizing spike begging to be released. She leaned in close to his face, her lips almost touching his.

"The one name you can call out tonight is mine, got it, Lizard?"

He smirked before forcing his helm forward, slamming his lips against hers once more before pulling away.

"Whatever you say, Lady Bug."

She smirked before pecking him on the lips.

"Good boy."

Grimlock snarled playfully at her at her remark. The Dinobot leader shivered as her hips began to grind against his, however this time, there was much more force. He groaned and let his head fall backwards.

His red optics snapped open upon hearing a faint click and pulled his head up to see that delectable valve right above his face. Lubricant dripped down Shrapnel's thighs and onto his chassis. He licked his lips before looking up to look at her.

"I've always wanted you to sit on my face like this."

She giggled. "Well it looks like your lucky day, lizard."

She lowered her hips, and just when her valve was in reach, Grimlock's glossa darted out and pressed hard against the sensor node above her moist entrance, causing her to cry out in pure ecstasy.

"Holy slag, Grimlock, y-you're so good at this!"

She felt his smirk against her and she keened, throwing her head back and spreading her legs, one placed on each side of her lover's helm.

Grimlock alternated between thrusting his think glossa into her dripping valve and licking along her thighs, teasing to her no end. Finally, she yelled out, wrapping her thighs around his helm and slowly began to hump his face. She cried out when his glossa curled and struck a particularly sensitive cluster of nodes inside her valve.

"Ooooh, Grimlock! Holy slag, I'm gonna- oh fuck I'm gonna overload!"

The Insecticon screamed as a powerful overload ran through her frame, her thighs tightening around the Dinobot's helm and her valve clenching at his glossa. He licked at the rush of lubricant that gushed out of her valve, savoring every last drop of it.

Shrapnel shook as the aftershocks of her powerful overload still jolted through her. She managed to unwrap her legs from around her lover's helm, backing off enough to see him lick his lips clean of the lubricant she squirted onto his face.

She blushed. "I-I'm sorry. I got carried away."

Grimlock smirked, licking up the last trace of her orgasm off his face. "It's alright babe, that was so fucking hot. You know how riled up I get when you used human slang in the berth."

Shrapnel smirked and giggled. She let her servo drift down to her lover's interface panel, rubbing and teasing the seams. His breath caught in his throat, and she slid down his body until she came to face his panel, kissing it softly in places where she knew it would drive Grimlock wild.

"Open up, love."

He couldn't resist such an invitation. There was a push of air and a faint click, and Grimlock moaned as his pressurized spike was finally set free.

Shrapnel licked her lips in delight. She always loved how big her lover was. Her glossa snaked out, and she dragged it all the way up the underside of Grimlock's spike, flicking the tip over the slit of his arousal, licking up the pre-fluid that escaped.

Her soft digits wrapped around the base, pumping slightly as she wrapped her mouth around the head of her lover's spike, her glossa flicking over several nodes that she knew by spark.

Grimlock nearly sobbed as Shrapnel took him into her mouth. She felt so soft and warm and wet, and it took every single ounce of his willpower not to begin thrusting into her mouth. Instead, he tried to relax and let her work, but found even that to be difficult when she began sucking, the suction almost driving him over the edge.

"Shrapnel! Holy shit!"

He pulled his helm to look down at her face as she swallowed his entire length, her smooth and wet throat cables contracted deliciously around him. She looked back at him and smiled around his spike, giggling slightly, which sent wondrous vibrations through his intimate areas.

He moaned loudly as she swallowed around his again, her servo still pumping around the base.

"Oh fuck, babe! If you keep swallowing me like that, I–oh frag, I don't know if I'll l-last much longer."

Grimlock let out a groan of disappointment as he felt his lover smirk around his spike, and swallow one last time before letting him slip from her mouth, a trail of oral lubricant connecting them.

Shrapnel licked her lips before pulling herself up, holding the base of her lover' spike.

"As much as I'd love for you to overload in my mouth, I'm afraid I have other plans."

The femme smirked and gasped loudly as she sank down his Grimlock's large spike, the two of them letting out moans of shear pleasure. When buried to the hilt, she exhaled, letting herself adjust to her lover's girth and length. If there was one thing she loved about Grimlock, it was his perfectly modeled spike.

"I want you to overload inside of me tonight, love."

Grimlock groaned softly as he felt Shrapnel's wet valve clench and contract around him, pulling him in as deep as he could go. He wanted so bad to thrust his hips up into her, but stopped himself from doing so, letting her adjust to his size.

Primus, no matter how many times they did this, she was still as tight as ever.

"Frag, you're so tight and wet. If you let me go, I'll give you the ride of your life."

Shrapnel opened her optics and glanced at Grimlock, her optics glazed over with pleasure and lust.

"Oh no, not tonight love. I'm in charge."

The Dinobot leader groaned as she began to move her hips at a slow pace, the wet slap of her aft against his pelvic region nearly driving him insane. He felt her clench around his spike tightly again as she overloaded for a second time, going slightly faster as the head of his length bumped against the back of her valve, brushing against her ceiling node.

"Oh fuck, Grimmy. You're just so fucking big and long and oh so perfect. It's as if your spike was just made to fuck my valve. Every time you cum inside me makes me go over the edge again, filling me to the brim to where it leaks down my thighs! I always feel so full when I'm with you like this. Shit, I wish you could stay inside me forever and give me an endless overload after overload! It'd be like I've died and joined the well! Oh Primus!"

That was it.

That was the last straw.

Grimlock roared as he pulled against the stasis cuffs around his wrists, snapping them in two. His lover gasped as she was suddenly on her back, the head of her lover's thick spike pressed against the back of her valve once more, before Grimlock slammed into her, hard.

She screamed as she wrapped her arms around his broad shoulders, scraping her claws over the metal plating. Grimlock had her legs placed over his shoulders, and thrust into her fast and hard at a new angle, hitting her ceiling node with every movement.

"Grimlock! Oh shi– Ahh! I'm gonna cum!"

"Fuuck! Shrapnel! Hold on, babe! I'm almost there!"

"Slag, slag, slag! Oooh frrraaaagg I'm overloading!"

Grimlock literally roared as Shrapnel's valve clamped down on his spike, contracting around him and overloading into his lover's valve. He continued to pump into her, letting them ride our their powerful overloads, letting her valve clench around him as she came down from her high. She groaned and nipped at her neck as she clawed at his back, transfluid filling every inch of her valve.

The Dinobot finally gathered the strength to push himself up, and slowly pull out of his lover with a pop. She groaned with disappointment at the lose of his spike, but moaned when his transfluid slipped out of her to run down her thighs.

"H-haa. I wish you could stay inside me."

"Hehe, I think we'd both like that."

They both shared a laugh before letting their lips touch, deeply kissing each other. Grimlock pulled the covers over their helms as Shrapnel giggled, Grimlock's hands roaming to her chest again, rubbing her bust.

"Oh love, you're gonna get me excited again."

"And who says I don't want that?"

The femme sighed. "I'm tired, you old horn dog. Maybe after a nap."

How could he deny her. He reached for something in the nightstand and pulled his arm back. He raised one of her legs, cleaning her thighs of lubricant and transfluid with a cloth. She gasped, heat returning to her face as he massaged over-sensitive areas. Shrapnel groaned as Grimlock's fingertips traced over the scratches he left on her aft and thighs, eyeing the paint transfers that were there as well.

"I'll buff those out for you later."

She laughed. "What good would that do? If I let your buff them out, ten klicks later they'll be back. With even more than there was before."

Grimlock chuckled, his laughter booming. He leaned down and kissed her on the lips again, wrapping his massive arms around her waists, and pulling her close.

"I love you, Lady Bug."

"I love you, too, Godzilla."
