   Summary

   Greedy, greedy, greedy, greedy. That’s all you could think to yourself as you watched them, heat burning in your belly.

   Sentinel Prime, sub-commander of the Elite Guard of Cybertron (as he so loved to remind you) was bent over, hands gripping hard at the sheets. Behind him, Optimus had a firm grasp on his hips, thumbs rubbing over the seam between where waist met pelvis.

   Or, you watch your boyfriends get it on, indulge in some size difference, and make the most erotic cybertronian-on-human sex tape the world will never see.
