Notes: This was sent by anonymous. Thank you for sending through. I had lots of fun with this with our favourite yellow bug. I got very carried away with it but couldn't help myself. Hope you like. I understand not everyone is a fan of robots x humans but we all live in a strange world. I could go on about how it could be possible with the small robots. We all have our kinks. Enjoy 😀

I accept Coffee! ☕🥰

Bumblebee had been away on a mission for Optimus. It felt like an eternity since you last saw him, and missed him everyday. Of course you both would stay in contact while he was on his missions but it wasn't the same as being with him.

Being his girlfriend you worried, always. Not many knew about your relationship with him, only Dot, but she was your best friend and you trusted her to keep quiet about it, at least for now.

Neither of you really knew what might happen if the world was to find out and you weren't really ready for that to happen just yet.

Finally, he came back, and you both didn't hesitate to have a date night. You wore a floral dress, his favourite, and also his favourite perfume honey smell on you.

Bumblebee took you to the drive through theatre before driving you back to your home. You loved this evening, you loved having Bumblebee back.

Back at your place, Bumblebee had come into your garage that was big enough for him, and also considering his small scout size it was perfect. You loved it when he stayed over, because it meant you both could have more time together without interruptions. You even pretty much moved your bedroom in there just so you both could sleep together in the same bed.

"Bee..." You whisper his name between heated kisses as he holds you up close to his face under his servos, your own hands running up across his cheek plating making him moan lowly against your lips.

"Y/N." He whispers back, blue optics foggy and illuminating across your beautiful face. "Primus you're beautiful."

"And you're very handsome." You smiled through a gentle giggle before feeling his digits sneak under your dress making your breath hitch, loving the feel of his digits dancing across your skin.

You didn't want his favourite dress to rip so you helped yourself out of it, letting it pool around your ankles and reached up for him again. When he saw your undergarments he couldn't help but smirk. "Yellow?"

"Yeah." You can't help but let out another warm giggle between heated breaths. "You know it's my favourite colour."

"That I do. Looks nice on you." Bumblebee smiles warmly.

He picks you up then, carrying you in his arms bridal style making you giggle and kick your legs gently in glee, making him chuckle lightly at your actions before placing you on the bed.

You had made sure to have a bed made that wouldn't break under Bumblebee's weight. The last couple of bed frames had completely collapsed.

Once he laid you down and climbed up at your side, his servo ran up your thigh and across your hips. Your hand moved up along his arm tenderly, staring up at him lovingly.

"I missed you." You say to him, letting out a hitched breath as you feel his servo roam down between your legs.

"Yeah, I missed you so much. It's always so hard being away from you for long periods of time." He sighs, but it turns into a smug smile as he felt just how soaked your undies were. "Already? I haven't even done anything. Do I just have that effect on you naturally?"

"Yes..." You answer through a soft moan, legs spreading more for his servo. "I've been wet since the movies."

"Well, I better not leave you neglected too much longer."

He carefully tugged down your undies, flicking them away before you helped yourself to unhook your bra and aiming it over Bumblebee's helm, only to have poor aim and have it getting caught at his horn making you cover your mouth to prevent yourself from bursting out laughing.

"Do I rock the look?" He joked lightly, flicking the bra off from him and gazed down at the sight before him. He felt incredibly lucky to have a girl like you in his life. You were so beautiful.

Giving you a tender smile, he then leaned down between your legs, pushing them gently apart and dragged his glossa across your damp core.

Your hips arched up from the contact, moaning as he did it a second time, and a third, right before you felt his thick glossa sink into your depths.

"Bee!" You cry out his name, hands grabbing hold of his helm and the other wrapped around his horn to keep him against you.

He let out a long hum that vibrated against your core and shook through your withering body, your moans growing louder as you didn't hold back. It was always good to not try and be quiet.

His glossa invaded your depths, rolling back and forth along your inner walls and curling skillfully. You rode his mouth, rocking your hips and holding his helm as loud squeaked gasps left our moist lips.

This went on for a moment more before he moved away. You pouted, and you heard him chuckle at your reaction.

"Don't worry. I just want to make sure you're ready for me." He says, crawling up over you smaller body.

Bumblebee always made sure to never hurt you, to prepare you as best he could for him to take you on his cable. Though he was a small scout, he was still much bigger than any human.

You nodded, letting out heavy pants before feeling his glossa run across your breasts, sucking on each of them, while his free servo moved down between your legs again and gently teased a digit against your core making you hum in delight.

When you felt his thick digit push in you clenched immediately, craving his curling digit as he stretched you. Looking up at him you saw that smug smile on his adorable face.

"What's got you smug?" You managed to ask, hips bucking a little when he started to gently rub your swollen bud with his other digit.

"I just feel like a very lucky bot, to have a pretty girlfriend like you, all spread out for me, soaking wet, and making such beautiful sounds."

"Is that all I'm good for?Just sex?" You can't help but tease, letting out a moan as he added a second digit, stretching you further.

"You're good for so many more things, promise. One day, when our worlds are ready, we won't need to keep this a secret."

"That sounds wonderful. Now, please, I want you to fuck me." You grin softly, making him chuckle back lightly.

"I think you're ready enough. As my girl wishes."

Once his digits were gone you felt empty without them. Hearing that familiar metal plating shifting you glance down between you both, biting your lips as you see his pulsing cable emerge from its housing.

You were always allured by the smooth long cable, bright yellow illuminating along the ridges wrapped around the base. He was so big, but you were capable of taking him before.

Bumblebee loved it when you started, it gave him that little bit of ridiculous pride and confidence. Gently, he took hold of your thighs, pushing your legs apart further and leaning down over you.

He kissed you. Always so gentle. His cable slid up between your folds and lubricated his length, before he pressed directly against your core, tip penetrating your depths.

"Bee..." His name moaned from your lips feeling him filling you inch by inch, slowly, but you needed it. "It's alright...I can take it."

"I don't want to hurt you..." Bumblebee whispers followed by a throaty moan. "By the all spark...so tight."

Reaching up you touch his face, running your thumb under his optic tenderly. "I want all of you, Bee. I'll be fine, I promise."

Finally, he let go. Balancing himself he pushed his waist further up against you, cable descending into your depths more as you clenched tightly around him, welcoming every pulsing inch.

Bumblebee watched himself disappear inside you, before his optics inching up to your stomach where a noticeable bulge was formed. It happened each time you both interfaced, or on human terms, had sex.

He was always so fascinated by it. Moving his servo he brushed his digit over the lump, vents hitching while you arched up your hips as your hands grip into the sheets under you, loud moans lingering from your open mouth as he fully filled you. Just what you needed.

"Move, please." You manage to gasp out through the pleasure boiling through your entire body.

Obeying your command he did that for you. His servos gently grip at your waist, he slowly pulls out, watching as his cable emerges from your core, coated in a mixture of your juices and his fluids, before slowly thrusting back into you again.

Each thrust sent a pulsing jolt through you, soft moans and heated gasps as he filled you over again slowly. Your legs wrap around his hips, thighs pressing against his yellow plating, pulling him closer and tighter into you.

Bumblebee balanced himself over you perfectly, his movements now short due to you holding onto him tightly, and this only encouraged him to pick up his movements, cursing softly out loud. "Frag..."

You weren't too far off. He had already worked up a storm with you that was threatening to break loose, but did your best to hold it off, just so he could catch up.

His movements grew shorter, stronger, but he was still holding back, as he always did. You understood though, he didn't want to lose control and end up hurting you by accident.

Perhaps one day, but this was incredible for both of you, being with him and feeling his pulsing cable filling you over again, pushing your limits.

Your juices and his lubricants dripped from your core and ran down onto the bed, soaking the sheets as the bed rocked a little under you both.

Bumblebee was practically grinding against your core now, barely leaving you as he groaned and vented heavily, servos tightening around your hips, before he dove down towards your open mouth and kissed you passionately, swallowing your sudden cry of pleasure as you came around him.

His hips jerked and you felt his cable sent an electric pulse through your core as thick strips of his fluids started to fill you. While kissing and clinging onto him, your hand moved to the bulge, pulsing and growing larger feeling his fluids fill you.

Breaking the kiss, Bumblebee vented heavily before kissing the inside of your neck, sucking against your skin gently as he caressed your entire body, worshipping you.

You welcomed his tender touches, his kindness, everything about him was simply beautiful and perfect.

After a time he slowly pulled out from your core, watching as his cable emerged and popped out, followed by his fluids that filled you.

Your belly still felt full which you loved, and ran your hand across your belly while letting out a hum of delight.

Carefully he moved to your side and laid on his back, bringing you closer against his chassis and the blanket just for you, wrapping his protective arms over your body as you nuzzled into him.

"I love you, Bee." You whisper into his neck as you slowly let sleep take over.

"I love you too, Y/A." Bee answers.

Indeed, he felt incredibly lucky to have you in his life.
