It's Wheeljack's and your anniversary. You've planned a nice week-long vacation, but Wheeljack would rather work, resulting in your first fight, which even Ratchet is not pleased about. Wheeljack discovers your plans and tells you he's happy you planned this. The vacation is on, and the first day is insanely fun.

(Y/N)'s P.O.V.
I've been planning a weeklong trip for a while now, and it's finally the week. Wheeljack has been working hard and needs a vacation. There's still a couple of things I need to do, like getting permission from Prime to let Wheeljack have a week off. I should have fine before booking everything; Prime would have waited until today to tell Wheeljack he has a week off. To make matters worse, Wheeljack is in a mood. I'm currently in bed with his shrunken form as he works on the laptop which shrunk with him. Wheeljack has an arm wrapped around me which is why I can't leave.
"Babe, I have to get up."
All I get is a growl.
I'm not lying when I say I have to use the bathroom, which gets Wheeljack to let me go. I grab clothes to take a shower and get ready.
Wheeljack is too focused on his work to know I'm not next to him, which is good today.

"Oh, for Primus sake, can't you not meditate for one second!?" I hear Ratchet rage.
How the hell is he and Drift together?
"Ratchet?" I ask.
"Hmm?"
"Is Wheeljack due for a check-up?"
"Thank Primus he's not," Ratchet replies.
I laugh and walk away to find Prime.

"Good morning, (Y/N), "Prime says as he picks me up.
"Good morning, sir; I've come to ask if Wheeljack can have a week off?"
"He does need a break," Prime comments, "very well; Wheeljack may have a week off."
"Thank you, sir."
I am let down and head to my room.

Wheeljack had fallen asleep while working. Good, there's a new more things I need to do, like pack, and I'd like to keep this vacation a surprise.

Wheeljack is up an hour later, rests his helm on my shoulder — which isn't heavy when he's the size of a human — and tiredly says good morning.
"Good morning, I have a surprise for you," I happily say.
"Umm...I wanted to work in the lab," he says, "I should be finished by the end of the week "
"But it's our anniversary, and I planned a week-long vacation that I know you need."
"But, I'm close to—."
"Frag you, Wheeljack! Work is more important than our anniversary?!"
I get off the berth and leave the room via the human-sized door, allowing me to slam it shut.

Wheeljack's P.O.V.
(Y/N) has never done this before. I can't believe it, (number) years together, and I just caused our first fight and on our fragging anniversary of all days. It's our first fight; I don't know if I need to go after her or leave her alone.
Not even five minutes pass before Ratchet barges in, also shrunken to the size of a human, which I should be thankful for.
"WHAT THE FRAG IS WRONG WITH YOU!" He rages, "TO FIGHT WITH (Y/N) PERIOD, BUT TODAY OF ALL DAYS!?" I didn't think he'd punch me, causing me to fall on the berth, "YOU BETTER FIX THIS!"
He slams the door closed behind him.
I could use the vacation, but I'm almost finished with a project.

Prime also scolds me as I walk down the hall before telling me where (Y/N) is.

"...I know he's a scientist, but he's never refused to spend time with me," I hear (Y/N) talking on the phone, "well, I'm going on this trip myself."
I walk into the room as (Y/N) puts her phone in her pocket and stands up. I swiftly move to hug her from behind. (Y/N) turns around and hugs me, but I know she's still furious at me.
"I'm sorry, (Y/N); I'm an idiot putting work first period, but today of all days," I pull out the paper from my pocket, "I'm happy you planned a week at (location). I lost track of time and didn't know it was our anniversary until today."
"But you never forget anything important."
"Which means I've been working too hard."
I pick up (Y/N) bridal style and carry her back to our room.

I lay on the berth with (Y/N) laying on my chassis. She moans as I rub her back. I take this as she forgives me.
"I'm sorry; I hope we never fight again."
I squeeze her tight — but not enough to break bones. We end up falling asleep.

(Y/N)'s P.O.V.
We slept until noon. The good news is our destination isn't too far away. We'll be there by dinner. It's fun having Wheeljack's bipedal mode the same size as me, but damn, is his holoform sexy.

I fear trouble will start as we drive by a fireworks shop, and Wheeljack makes a U-turn. I'm probably going to regret this, but I let Wheeljack buy some fireworks. We're told about a beach people are allowed to launch fireworks at.

We discover a party happening at the beach, and the humans are happy we have fireworks. It's seven at night; we won't have to wait long to launch the fireworks. In the meantime, Wheeljack follows another couple's lead, and we dance by the bonfire.
"I think this is our first romantic dance," I comment, "and you're doing great."
It's fun dancing in the sand with Wheeljack. Time flew by, and it's time to launch the fireworks.

Wheeljack's P.O.V.
This is one insane party. I didn't think Y/N) would be drinking, but not enough to get drunk. This party lasts until midnight, and (Y/N) is exhausted.

She's half asleep when we get to the hotel, sleepily telling me what room number we are.
I lay her on the bed, getting on top of her.
I thought she'd fall asleep, but she pulls me in for a kiss. I can't resist touching her breasts as we kiss, sneaking my tongue in her mouth.
She's too tired for fragging. We have a nice week-long vacation.
I lay next to her, holding her close to me.
"Thanks for planning this; I need it. I know the rest of the week is going to be a blast."
(Y/N) falls asleep quickly. I make sure she's covered with a blanket before going to sleep.
