This is a short story. I was bored and this came to mind
I suddenly was started out of recharge when I felt a rapid tapping on my shoulder plating
"Hmmmm?" I said sleepily
"Ratchet you were screaming in your recharge" my birthmate stated, "Are you ok?
"Ju-(yawn)-st a bad memory… Don't worry optimus"
He started rubbing my back plating in a circular motion, just like you would a sparkling. I was surprised that his touch was so soft, considering his hands were so large and rigged. He suddenly rubbed a hot spot, making me shiver with anticipation. I started touching his chestplates. He must have realized where this was going. He put his hand up. "Not now ratchet". He then kissed my shoulder.
"Try and get some recharge, ratchet… I've noticed you haven't been getting lots of recharge lately and you need some." Optimus nagged
"Yes mother" I retorted. That earned me a slap in the back of the head.
"Owww…" I whined as I rubbed my processor.
"I mean it ratchet!" this statement wasn't a request, it was an order.
"Yes sir" I mumbled as I turned onto my side and started to drift back into stasis
"Goodnight old friend" be whispered as he rolled over and joined his berthmate in stasis.
