(Y/N)'s plan to wash Optimus' alt mode turns into a game of hide and seek.
(Y/N) is happy her family thinks Optimus lives on a semi-truck, though it's strange; why not an RV? The family is out of the house before she wakes up at noon.
Shit, I didn't mean to sleep this late. (Y/N) thinks as she looks at her phone.
She eats quickly before going outside, realizing how hot it is. Deciding to wash Prime, knowing he can feel her washing him.
As she washes Optimus, she can hear him moan and purr in pleasure. Once done washing Optimus' alt mode, she comments on how sexy he sounded while moaning. As (Y/N) puts the supplies away and takes care of the dirty water, Optimus activates his holoform and takes off his shirt. He hugs (Y/N) from behind.
"You must be punished," Optimus declares.
(YN) breaks free from his hug and starts running.
"You'll never take me alive, Prime! Ninja vanish!"
Optimus didn't think (Y/N) would drop a smoke bomb. While questioning where she got a smoke bomb, he knows (Y/N) ran to her room.
You're terrible at hiding (Y/N).
"If you don't show yourself, the lesson will be severe," he warns as he enters her bedroom. With his back turned, (Y/N) came out from under her bed and tip-toed to her mom's room to hide in the closet while giggling silently.
She successfully reaches her new hiding spot before Optimus comes out of (Y/N)'s room, giving her one last warning while scanning the room for (Y/N).
He enters the parents' room and smirks as he opens the closet door. (Y/N) doesn't know she's been found until Optimus picks her up bridal style, resulting in a squeal.
"You can run, but you cannot hide," Optimus says as he pins (Y/N) against the wall, use one hand to put her hands above her head, uses his other hand to cup her cheek, and kisses her. (Y/N) is shocked but returns the kiss, which turns passionate.
