Optimus tears himself away from the conversation with the human and turns to his mate. “Yes?” Oh that didnt come out nice at all. He clears his vocalizer and tries again. “Yes my love?”
He moaned as Prime started nibbling at his neck cables, and his hands temporarily faltered, before he regained his bearings, and increased his massaging.
Moments like these made the years of war almost worth it. Starting out, he’d have never pictured himself in a moment such as this one - on a foreign planet, being hunted by some of the locals and protected by others, alone in his quarters with Optimus Prime, rubbing at Prime’s audial fins while Optimus simultaneously nibbled his neck cables - it was a dream come true.
"Save the talking for later, Prime. For now… cuddles and neckbiting."
He hums in respond and obeys. The nibbles get a little harder and turn to bites and his frame lays more fully on the one beneath him.
Caught he recalls there was something he was going to ask Sideswipe before he started touching his audials. It’s forgotten just as quickly as it comes though.
There’s a brief grunt as Prime lays more fully on Sideswipe, but it was more of a natural response than an indication of discomfort. He kept up the massages with one servo as the bites get harder. Primus, if this kept up, he’d release before he could get his crotch plate off.
He turned his helm a little, bringing Prime slightly closer, before beginning to nibble lightly at the audial fin that currently was not being massaged.
