Sunstreaker was down visiting earth after Optimus assigned you to help out bumblebees team which he didn’t like after all you two are lovers so he didn’t like to stray far.

It has been a couple months since he’s been on earth and him and sideswipe reunited and were getting close much to yours and Strongarms dismay, mainly yours as he was already a trouble maker.

At the moment you are lecturing both sideswipe and SunStreaker about a stupid prank they committed.
