Sorry for the delay! I was working on this forever, trying to perfect it for you guys. The end of the chapter is kind of abrupt, sorry. But it's packed with things I've been dying to write, and let me tell you, this chapter is why Easing Tension is rated M. I really did try hard on this, so don't forget to tell me what you think!

Knockout banged on Soundwave's door, eager to see him. After a few moments without a response, he started to wonder if the Mech had gone to recharge. He pressed his audio to the door and heard something, so he knocked again.

Soundwave finally opened the door and then shut it immediately. Knockout swore internally, remembering what he'd said the last time they spoke. "Soundwave! I know I was a total glitch. I got distracted by something and I took it out on you. I'm really sorry." There was no response and Knockout's worry worsened. "Soundwave, please open the door." The door finally opened. "I…"

Soundwave stood there, water dripping off him. Knockout's mandible dropped as he looked over him, optics setting on the suds dripping down the inner side of his leg. His engine let out a little growl of approval and he quickly coughed to try and cover it.

Soundwave took a step closer. To Knockout's shock, he reached up and touched Knockout's mouth. "Knockout: damaged?" His servo ghosted over to the dent in his shoulder.

"It.. It was nothing. Soundwave, I'm sorry."

"Apology: accepted," he said without hesitation. Soundwave tugged Knockout inside by the collar, the door sliding shut behind them. Soundwave pulled him to the berth, walking backward until he fell onto the cushioning, Knockout over top of him.

"Take it off," Knockout said, touching the rim of the face screen. Soundwave reached up and unlocked it, pulling it away. Knockout drank in his expression; mouth parted and slanted optics darkened with need. His face was wet from the wash. Knockout bent down and pressed his dila against Soundwave's bottom lip, sliding over the top as he licked away the water. Soundwave leaned up and their lips brushed. He rubbed his knee joint against Knockout's hip.

Knockout crushed their mouths together. He winced as the crack in his lip was grazed. Soundwave moved his mouth over the wound, dila gently pressing against it. The leak had stopped, but he could still taste the Energon.

"Damage: culprit?" Soundwave inquired quietly.

"Just Breakdown. We hit each other all the time," he lied. He had a feeling Soundwave didn't buy it.

"Knockout: safe now." Soundwave kissed the undamaged corner of Knockout's mouth and Knockout kissed harder, wanting him too much to care about the sting.

"I want you so badly," Knockout breathed. He slid a servo down Soundwave's hull, settling on his lower stomach. Soundwave sat up and turned over onto his knees. Knockout groaned, putting a servo on Soundwave's thigh. "As incredibly sexy as your aft looks in this position, I think I just…" Soundwave turned back around awkwardly. Knockout looked at him admiringly. "Yeah, I like facing you."

Soundwave's spark turned slightly. Knockout was totally different from any of his previous lovers. He put a servo on Knockout's interface panel, and Knockout slid it open. Knockout's spike was as flashy as the rest of him, red with a white underside. Soundwave slid open his rear interface panel, lubricant dripping from it as it opened. Knockout growled, wiping up some of the lubricant and slicking it over his spike. He pressed his spike against the other's port entrance and paused. He pushed a little more and stopped. "You haven't fragged in a while, have you?"

Soundwave scowled. He would never admit exactly how long it had been, but part of him thought Knockout could tell. He wrapped his legs around Knockout's hips to pull him closer.

"No really," Knockout said. "It'll hurt like frag. Here…" He pressed a digit against Soundwave's port, and without breaking his gaze with the other, pushed inside. His optics darkened as he pushed deeper, relishing Soundwave's expression. "I'm going to make you feel so good," he growled in Soundwave's audio. He pressed another digit in, stroking slowly. He pushed in a third, wishing his digits were thicker so he could stretch Soundwave a little better.

"I'm going to go slowly." He pressed the head of his spike against Soundwave's port and pushed, sliding in painfully slow. Soundwave's optics shut, his helm falling back against the berth. Knockout groaned long and deep; he was barely half way in. "Oh frag me, you are so tight." He wanted to just push into the wet port as hard as he could, consumed with the sensation. But he used all of his will to pull out and push in again.

"Soundwave: needs more," he begged.

"I'm getting there," Knockout breathed, moving at a slow and steady pace. Soundwave was fitting him better with each thrust. He drove in deeper and the purple mech pulled him closer. He looked down at Soundwave's closed lower paneling. He pressed his servo against it, feeling the heat. "Open it," he grunted. Soundwave hesitated before opening. His spike slid out, and Knockout stopped thrusting. "Whoa." Soundwave tensed with embarrassment and Knockout noticed. "Sorry, it's just… you've got a very pretty, ribbed spike."

"Definition: ribbed?"

"The glow rings are ribs." He wrapped a servo around Soundwave's spike, sliding up and down. Soundwave's legs trembled. Knockout began to pump again, faster than before. Their frames rocked hard against the berth. Soundwave's processor spun from the sensation of Knockout's servo on his spike, and the hard pumping against his port. "Soundwave," Knockout purred. "Do you want me to hit your sweet spot?" Soundwave nodded, pretending he knew what the red mech was talking about. Knockout lifted one of Soundwave's legs over his shoulder and thrust in again, this time hitting something new. Soundwave's legs trembled furiously, his servos digging into the berth padding.

Soundwave felt an unfamiliar energy sliding down inside of him, something powerful. It felt slow and fast at the same time, the energy falling toward his interface region, the power of it like a speeding train heading his way. "Feeling: unfamiliar…" Soundwave moaned.

"I think you're close," Knockout murmured, feeling Soundwave's port cables twitch around his spike.

"Nngh!" Soundwave burst out, unable to silence his vocals. The overload hit him hard, and he arched up, digging his digits into Knockout's back. Control of his vocals was unresponsive, and he continued to cry out as spasms tightened the cables encircling his port. Knockout groaned from the tremors, engine roaring as he overloaded too.
