    TF Kinktober Day 19: Alt Form Sex

    When Megatron walked into Minimus fucking Rodimus as a turbofox, he didn't think he'd be joining in, but that's exactly what happened. And he could never pass up the chance to get a knot in his valve.

    Summary

    When Ratchet helps Jazz out of a magnet-play-gone-wrong situation, he decides that Jazz needs supervision if he's going to mess around with bondage. Jazz doesn't seem to mind the idea of Ratchet sitting in - he even encourages Ratchet to take a more active role. Which just makes it even more confusing when everything goes wrong.

    Summary

    Noah’s sat behind the wheel like he’s in control. He’s not. Mirage is the one driving- has been since the second they left the garage.
    And as traffic stalls and the sun burns overhead, Mirage decides it’s the perfect time to play.

    A spike pressing up from the seat. Heated cables sneaking into Noah’s waistband. The soft hum of a voice through the speakers:

    “Keep driving, baby. Don’t let them see how good I’m making you feel.”

    It’s not their first time. But it’s never been this public before.
    And Noah? He’s trying really hard not to cum in the middle of traffic.

    Summary

    “So you’re that type of mech, hm?”
    Cliffjumper’s frown deepened and he barely turned his helm to glare over his shoulder.
    However, he quickly found it was difficult to know where to point his glare when the enemy was stuck in his alt-mode. If he was a car it would be easy, and Cliffjumper had some idea of where to look at a flight-mode. He wasn’t dumb.
    But it was a harder call when the leader of the Decepticons was a gun.

    Basically silly G1 fun meets gunfucking.

    Minimus paused once in his irreducible mode. Allowing foreign circuity to readjust was only part of it. Like this, without the layers of armor that he depended on, the layers that made him him, he could feel the need– the want even stronger.
