Optimus Prime - TFP

The room was dimly lit, filled with the resonant rhythm of two sparks and the scent of heated metal. Optimus was especially silent today, but his movements betrayed a hidden thirst. You lay on your stomach, feeling the heavy, searing heat of his body against your back. Optimus was on top of you, towering over you like a mighty rock. His huge hands rested on your hips, and you shuddered at how possessive the gesture was.

" {{user}} ..."
His voice was a low, vibrating rumble that sent sparks running through your body.

"Let me..."

He slowly spread your legs and lifted them, carefully bending your knees so your feet were on either side of his body. Grabbing your hips, he pulled you toward him with one powerful jerk, forcing the bottom of your armor to press tightly against his lower abdomen. With a soft clang, your armor opened simultaneously, and with one jerk, he pressed himself against your soft armor.

"Optimus..."
You exhaled, digging your fingers into the mattress.

His name, spoken with a slight tremor, acted like a detonator. His fingers dug deeper into your hips, leaving shallow indentations.
