“Hands on the wall, legs together,” Sideswipe ordered. Perceptor rose to his unsteady feet and obeyed, leaning heavily on the wall and not looking back to the other mech. Sideswipe pressed himself along Perceptor’s back, holding his hips steady, and squeezed his spike between Perceptor’s thighs.
The thin sheen of lubricant leaking from Perceptor’s valve down his legs eased the slide of the spike. Compared to normal interface, this contact was so light and fleeting, a horrible tease. He moaned with delight every time the ridges of Sideswipe’s spike rubbed along the valve rim, the flare of the head catching against his entrance, only to push past and away. So close, but never enough.
He wasn’t even near ready when Sideswipe bit the back of his neck and overloaded with a grunt, transfluid splattering on the wall from between his legs. Sideswipe pulled away and collapsed comfortably on the berth. After a few kliks of enjoying the fuzzy haze tingling in his circuits, he propped himself up and looked to his neglected partner. Perceptor obediently remained in the same position against the wall, the nervous shifting of weight from one foot to the other betraying his want.
“Clean the wall. You can finger yourself,” Sideswipe said.
Perceptor fell to his knees with a raw sound of relief and shoved three fingers into his valve. He slowly licked the tacky, drying transfluid off the wall, shutting off his optics until the world funneled down to nothing but the thick taste in his mouth, the feel of his fingers desperately scraping his insides, and the pounding of energon in his lines. When the overload finally hit, he toppled over to the floor with a shuddering moan.
Sideswipe let him vent until he was calmed down, and tapped the side of the berth beckoningly. His pet crawled to him and dragged himself up into the berth, curling up by his side.
“Good?” Perceptor asked sleepily, dim optics meeting his.
“Yes. You were very good,” Sideswipe said. ”You can recharge now.”
“Thank you.” Perceptor nuzzled his hip shyly and closed his optics. Sideswipe lay his hand on his curved helm and watched him rest.
