Ratchet struggles knowing he caused (Y/N) not to tell him about her pain until she was close to dying. He takes her to a place for a little vacation once she's recovered, where they frag.

Ratchet's P.O.V.
I sit by the bed, waiting for (Y/N) to wake up, hating I made her afraid to tell me if anything is wrong with her. I could have been responsible for her death. I know it'll be a while before she wakes up, but I'm not leaving. I wait two hours for her to wake up — holding her hand.
"Ratchet?" She tiredly asks as she looks at me.
I kiss her forehead, "why didn't you tell me you had terrible stomach pain?"
"I didn't want to stress you like when Soundwave tried to get me."
I hate how she confirmed I made her afraid to tell me something like this.
"I'm sorry I've made you afraid to tell me something like this, but I would have stayed calm."
I don't think she believes me.
Optimus suggests I go recharge for a while, and he'll stay with (Y/N). There's no point arguing with him.

Optimus Prime's P.O.V.
I sit by the bed, happy (Y/N) is ok.
"Thanks for convincing Ratchet to let me go on the mission; even though now it's on hold," (Y/N) says, "I know he worries I about me, but sometimes it's too much."
"You know how happy he is to have fallen for you and how happy you make him."
"I'm glad I met all of you."
She's still tired. She doesn't care I'm here as she makes herself comfortable to go back to sleep. Now Ratchet has me worried.

It seems (Y/N) sleeps a little at a time, which explains why it seems all she wants to do is sleep. Though Ratchet and I question how much has she gotten since her pain started? She could be trying to catch up on lost sleep.
While she sleeps, I talk to Ratchet about letting (Y/N) go back on missions. He knows she's skilled, and everybot protects all our human friends.

Four hours later

Ratchet's P.O.V.
"Here, drink this for now," I tell (Y/N), handing her a cup of broth, "I know it seems odd, but it's part of the recovery process," she takes the cup and drinks as I sit by the bed, "I was so worried I'd lose you. When you've recovered, I'm taking you somewhere nice and secluded to frag you until you can't walk."
She laughs, but I see her face turn red. She finishes drinking and hoes back to sleep.

(Y/N) fully recovered two weeks later. Optimus permits us to take a little vacation. (Y/N) is surprised at the location I choose for our vacation. She loves the room I booked though we'll likely be spending the day outside at the pool.

(Y/N)'s P.O.V.
We spend the day at the pool before dinner. After dinner, we enjoy the jacuzzi. I love sitting close to Ratchet as we relax. It's a nice relaxing twenty minutes before Ratchet kisses me. This turns into a makeout session before Ratchet carries me to our room.

We resume the kiss once we're in our room and I'm standing. He couldn't wait to take my bathing suit off, and I take his off. I figured he's ready after our makeout session. He lays me on the bed, clearly wanting to get right to it, but I'm not ready. Ratchet knows how to make me ready. Before I know it, he's in me moving slowly, but that doesn't last long. He smiles at my moaning.
"Y-yes!"
He kisses me as he keeps going for a few minutes before pulling out. He lays next to me and pulls me close.
"The next time you scream as you did before, I hope it's because you're delivering our child."
I doubt Ratchet would let me deal with pain like that again, even if it's during labor and delivery of our child.

Optimus Prime's P.O.V.
(Y/N) and Ratchet took a weekend-long vacation, but it's clear they needed it by how happy they are when they returned.
"Bet you they fragged," Wheeljack smirks.
"It's none of our business — though we might find out in a couple of weeks. We should be happy (Y/N) recovered and the couple is happy."
