Day 26: Clothing Sex
“You are the absolute worst,” Sunstreaker groused, dragging his brother behind him. “I must have been a sparkling murderer in a past life for Primus to have stuck me with you.”
Sideswipe still quietly giggled, letting himself be pulled along. He occasionally stumbled, but to save on electricity the High Priest kept the back hallways dimly light. Sunstreaker didn’t think Sideswipe was drunk - this time.
“ – hehe – his face – !”
“You probably scared a century off that mech’s life, Sides! Get in there!”
Finally arriving in front of his office, Sunstreaker punched in his security code. Once the slow-moving door opened wide enough, he shoved his brother through. Sunstreaker followed and shut the door behind them, ensuring it was locked.
When Sunstreaker spun around, he saw Sideswipe had plopped himself down behind Sunstreaker’s desk and was grinning at him. Sideswipe’s optics shone brightly, and despite Sunstreaker’s irritation, his spark gave a happy whirl.
“You cannot do that again. Ever. If that mech tells one of the other priests – ” Sunstreaker said. He strode over to loom above Sideswipe in a threatening manner. Sunstreaker even pointed a finger. Sideswipe just batted it aside.
“Oh, please. I don’t know if you’ve looked in a mirror lately, Sunny, but you are the hottest Priest in Primus’ service. I can guarantee that mech has thought about sitting on your lap in the confessional booth. And if he hasn’t – well – I’ve just given him some great self-service material.”
Sunstreaker’s frame flushed in embarrassment. Sideswipe had timed it just right. The parishioner had entered his side, then Sunstreaker had gone into his part of the booth. Sideswipe had snuck in right after. The commotion the two of them had made as Sunstreaker had attempted to get Sideswipe to leave had caused the parishioner to become concerned. Despite Sunstreaker’s reassurances, the parishioner had left his compartment had entered Sunstreaker’s. Only to witness Sideswipe atop Sunstreaker’s lap, one hand buried beneath his ceremonial robes.
It had taken many apologies and a rushed explanation that Sideswipe was his twin and a bit of a jokester. Finally, the parishioner had left, still looking a little confused. Sunstreaker had then dragged Sideswipe away, grateful Optimus was also taking confessions for the next few hours.
“That’s not – you – ” Sunstreaker rubbed the bridge of his nasal ridge and sighed. “What do you want?”
Sideswipe pushed himself to his feet and crowded in close. It wasn’t difficult to do. Sunstreaker’s office was basically a closet.
“You. Wasn’t that obvious?” Sideswipe’s voice was low and suddenly serious. The smile disappeared from his face and his gaze bored into Sunstreaker’s. “I’ve missed you. You never come home anymore.”
Sunstreaker ducked his head. “You know we’re not supposed to – ”
“You said we’re an exception.”
Priests were supposed to be chaste. They weren’t supposed to have mates. It was extremely unusual for someone with an existing bond to enter the Priesthood. Those that did, broke it. But Sideswipe’s and Sunstreaker’s bond wasn’t one they could even begin to think about breaking. Their spark halves literally relied on one another for survival.
It had taken some tricky interpretation of scripture, but Sunstreaker was allowed to regularly spark merge with Sideswipe.
“Yes, but – it’s still generally looked down upon. Most of the Priests don’t understand,” Sunstreaker hedged.
“But you understand. You know,” Sideswipe said. He took another step forward, pressing their chests together through their clothing. Sunstreaker hissed quietly as his spark surged against its crystal. “And I’m happy to fuck you anywhere, Sunny. You know I’m not picky.”
His hands dove back into Sunstreaker’s robes, one deftly finding its way to his chest plating and the other creeping down to his pelvic span. Sideswipe’s fingers stroked and plucked at sensitive seams normally hidden away by thick folds of cloth for the entirety of Sunstreaker’s day.
“So, you gonna let me make up for lost time on that cot you call a bed or you wanna wait until the weekend?” Sideswipe’s digits pressed against Sunstreaker’s central seam, rubbing over it, up and down – up and down in a maddingly slow rhythm.
“– I hate you,” Sunstreaker muttered. He nuzzled Sideswipe’s cheek, inhaling the scents clinging to Sideswipe’s clothes, so different from the ones permeating the Church. But familiar yet the same because they were the ones Sunstreaker always smelled on Sideswipe.
“No, you don’t. And I’m sorry about that,” Sideswipe said. He leaned back with a sad smile. “C’mon, sweetspark.”
Sideswipe knew the other door in Sunstreaker’s office led to an even tinier space that contained a cot wide enough for an average-sized mech. Or two average-sized twins accustomed to squeezing into spaces normally occupied by one person. They tumbled into the cubby, the door shutting behind them. The dim overhead light flicked on when Sunstreaker’s elbow hit the switch.
“Primus, it’s like they purposively wrap you up in ten different layers,” Sideswipe growled, his hands growing frantic as they pushed and shoved at Sunstreaker’s robes. “Ah, fuck it. I’ve got enough room, just open your panel.”
Sunstreaker froze, a bolt of fear going through him. He looked up at Sideswipe with wide optics. “I thought we were merging.”
“Oh, we are,” Sideswipe said. He sat up and straddled Sunstreaker’s upper thighs. With a single twist of his wrist, he untied the sash of his single-layer robe. The halves parted slightly, showing off his already exposed thoracic interior. His crystal wildly flickering, just barely cracked. Sunstreaker’s entire being yearned at the sight. “But I’m also going to ride the Pit out of your spike too.”
“I can’t,” Sunstreaker whined, turning his head to the side. “Sides, I can’t – please – ”
Sideswipe spread his knees, his robe swinging open wider. He rucked up the bottom half and Sunstreaker spied the glistening pleats of his valve in the darkened vee of his thighs. “You can. Primus didn’t strike you down last time, and I doubt he’ll strike you down this time either.”
Sunstreaker shoved a fist in his mouth and bit down as his brother’s wicked fingers stroked over Sunstreaker’s panel. He told himself it was an involuntary reaction when it transformed aside, when his spike extended straight into Sideswipe’s waiting grip. It felt so good. It always felt so good, but then again, giving in to temptation always did, didn’t it?
Sideswipe shuffled forward on his knees, cursing slightly when one hit the wall. Sunstreaker automatically reached for Sideswipe, trying to steady him.
“Ow. Fuck, you’re so hot like this. Look at you – still all wrapped up with only your spike and spark out. What would those congregation members say if they saw you now, huh? All laid out, looking like a gift for Primus himself? They’d probably cream their panels, holy slag.”
“Shut up. Shut up, Sides, shut up,” Sunstreaker begged. He reached up and tried to slap a hand over Sideswipe’s mouth, but somehow two fingers ended up between his twin’s lips instead. Sideswipe winked at him as he sucked on the digits, glossa lewdly swirling around them.
Sideswipe’s back arched as his crystal retracted completely. His spark spun wildly on its axis, enticingly throwing out tendrils to its other half. Giving Sunstreaker’s fingers one last suck, Sideswipe let them go.
Still stroking Sunstreaker’s spike, Sideswipe leaned down and kissed him. For the first three seconds, it was chaste. Just a simple press of lips against lips. But Sideswipe’s spark was a foot away from Sunstreaker’s. Sideswipe’s valve dripped lubricant and poured heat over Sunstreaker’s spike.
At the end of the day, no matter how much he wanted to be a good Priest – well, when given the choice between piousness and the sheer temptation of his twin – he wanted his twin more.
Sunstreaker moaned and surged against Sideswipe’s mouth, glossa probing past Sideswipe’s lips in a filthy kiss. He grabbed hold of Sideswipe’s hips and tugged him down, helping him line up their pelvises. They groaned in unison when Sideswipe bottomed out and Sunstreaker was glad he had a spare set of robes in his office. Fluid stains would make this set unpresentable.
“I love you,” Sideswipe sighed. He dropped his head down, forehelm resting against Sunstreaker’s. He shifted to press their chests together, their sparks eagerly reaching for one another.
“Spark of my spark,” Sunstreaker whispered. Their cores began to merge and Sunstreaker closed his optics to savor the peaceful bliss even as Sideswipe started grinding his lower body against Sunstreaker’s. “I love you too.”
Primus had truly cursed Sunstreaker. Called him to service but also gave him a bond he couldn’t break, to a person he could never stop loving and never stop wanting.
It hurt so beautifully.
