Note: Sorry for the short chapter. Next one should be longer, but I had a hell of a schedule and didn't have much time or will to write.

Lightly running his index finger over Perceptor's entrance, Skyfire could not help to note that it will take a really long time to stretch Perceptor enough to take him in. Well, no problem, as they did not have to go all the way in one day, so it was alright. And Skyfire would have a very nice recording to use later… Perceptor gasped out a moan, the light touches igniting so much pleasure.

"I… I should reciprocate…"

"You can. Later."

"But… Oh!"

Skyfire kissed Perceptor when Perceptor talked about reciprocating. Right now he wanted to touch… getting touched can wait later. And when Perceptor tried to say something again, Skyfire inserted his finger. Perceptor yelped instantly and the valve walls clenched down on Skyfire's finger. Half-worried about if they will ever going to go all the way and half-delighted by promising… squeeze, oh boy, Skyfire felt more perverted than he really was.

Skyfire carefully moved his finger trying not to damage Perceptor as much as possible. Luckily, the valve's lubricant eased that process significantly and soon Skyfire could insert a second finger. Perceptor groaned in a bit of discomfort as his valve was stretched. The sensation was very different from his past experiences; Skyfire was larger and somehow warmer, and Perceptor was not so sure if they will ever go… all the way…

"Tell me… Do you think about me when you… use that thing?"

Perceptor trembled when Skyfire's finger grazed over a sensor node. Heaving heavily, Perceptor nodded in awfully shy and conscious manner. Unlike his initial state of determination, Perceptor wanted to yield everything and just hid away. Perceptor rested his head on to the larger mech's shoulder. Skyfire could not resist a grin forming on his face. Humming in satisfaction, Skyfire rubbed on to one of the nodes, making several deep moans and staggered breaths from Perceptor.

"Should I go slower Percy'?"

"Mm… No… Keep going…"

Or not. When the siren blared through the entire Ark, the couple had to pause. Simultaneously sighing, they parted.

"Later?"

"… Yes, later."

Sharing a quick peck, they tidied themselves and headed out.

The battle was short, thanks to the two extremely angry, annoyed, needy, cranky, and usually pacifist scientists. When the two of them had to go thorough medical check-up, post-battle meetings, etc. the Autobots tried to keep the encounters as short as possible. And when the hassles were dealt with, they were too tired to do anything.

"… I hate battles…"

"… Me too... Tomorrow?"

"You better."

"I'll perform nicely."

Skyfire and Perceptor shared some words before they went to recharge. What a nice promise for the next day.
