~flashback~
"Sentinel! We're supposed to be studying for the exam, you know."
Sentinel grinned wickedly, never stopping his hands from mapping out the glass on Optimus' chest. He was pressed against his friend's back, hands roaming and caressing, playing a game he knew he would win sooner or later.
"Not as much fun as this, Optimus, and it is a form of study, if you know what I mean."
The body was starting to twist and tremble under his hands, a sure sign that they'd be back in their dorm before it got much further.
"You know I need to study for this class! You and Elita may not need it, but I do. Ah! Sentinel!"
Sentinel pressed his grin into the warm neck before him, nipping at the cables presented ever so temptingly.
"How about this then, we go back to our dorm and I'll make SURE you pass this test. I think that's a fair offer, don't you?"
The books were snapped shut so quickly Sentinel had to stifle a laugh. It was so easy to get Optimus riled up and willing to kiss for hours on one of their beds Sentinel would have teased him; if that wouldn't have reduced his chances for action anyway.
Still, very soon they were back in their dorm and Optimus dropped his bag with no concern for the items inside. It always turned Sentinel on that Optimus focused in on him with such intensity, like he was the only thing in the Universe.
"You going to make good on your promise? Or do I need to go back and get some real work done."
Sentinel growled, pulling the other mech to him with crushing force.
"You shouldn't tempt me if you aren't willing to follow through, Optimus."
A shudder as he nipped the sensitive metal of Optimus' chin.
"What if I was willing? Would you be mech enough to make it good for me?"
Sentinel stopped and pushed back, looking at his friend (was that even the right term anymore?), then leaned forward to put his mouth right alongside the other's audials.
"You wouldn't even be able to remember your name if you were willing. I'd make sure of it."
Optimus' back arched at the sound and vibration of the sinfully deep voice that assaulted his senses. His optics darkened and he pulled Sentinel into a scorching kiss before sending them both tumbling onto the closest berth.
It was both awkward and not, this new feeling, and there were times when Optimus almost pulled back. Almost ran out and left it behind because it was new and not new and exciting and terrifying all at the same time.
Sentinel's hands were everywhere. His glass, his antenna, his seams… it seemed as though he'd sprouted extra hands because there wasn't a square inch of Optimus that couldn't feel him.
Still, it was such a new feeling for him, one he wasn't used to at all. Sentinel was clearly experienced, but Optimus hadn't had a partner yet. His seals had been broken, who hadn't touched themselves after all, but he'd never felt comfortable with anyone before Sentinel.
He tried to reciprocate, his hands flitting almost confusedly over the blue plating over him, but then Sentinel would do 'something' and Optimus would feel like he'd lost control of his motor functions and have to start all over again.
A leg pressed between his own smooth thighs to connect with his interfacing panels and he bowed up off the bed, gasping and venting wildly. The thigh rubbed back and forth and Optimus found himself rocking into the sensation as it grew until he heard the 'whoosh' of the panels retracting.
His spike pressurized quickly, and he could feel the trickle of lubricants start to leak onto the berth as Sentinel's weight suddenly disappeared before his spike was enveloped in a slick heat.
"AAaaaaAHHH! Sentinel!"
A chuckle vibrated around his spike, making him squirm even more, before the heat retreated and came back.
And off and on and off and on andoffandonandoffandon…
Optimus was sucking air through his vents, trying to cool his overheating engine, as everything stuttered and whined and clanked together. The heat vanished from his spike and he heard himself whine before that same glorious mouth reached lower and nipped at the edge of his valve.
He choked/gasped as a finger and glossa slid teasingly over the rim before delving inside. It seemed as though Sentinel was bringing him to the edge of overload before backing off and it was maddening. Self pleasure had never ever prepared him for what this felt like. It was like comparing Seekers and Grounders; it didn't even have the same base in reality.
Then suddenly Sentinel was back at his mouth and he could taste himself through the kisses. Sentinel's spike nudged at his entrance once before thrusting in…
And Optimus cried out and tried to curl in on himself.
Sentinel, for his part, immediately stopped and looked down in shock. Optimus tried to relax, tried to force his body to flatten back out on the bed, but the all to sudden stretch of his valve was as close to torturous as he thought it could be.
Sentinel pulled back out , both of their charges diminished from the shock, and gently ran a hand down Optimus' arm.
"Why didn't you tell me? I would have prepared you better if I'd known you hadn't…"
Shame curled up in Optimus and he turned his head to the wall.
"I, ah, I didn't think it would matter. I didn't know you would have to do anything…"
And he hadn't. After he'd broken his seal, he'd never had a problem with his own fingers and hadn't even thought about what a larger item would do.
Sentinel vented and his spike panel slipped back into place, mood effectively killed, and walked to their shared water bucket. He took a clean rag and dipped it into the lukewarm water before returning to the bed and gently wiping down Optimus' interface array.
Optimus flinched with each swipe until Sentinel was done, then went to shut his panels before a hand stopped him. He gave a questioning look before hissing in surprise as a digit again breached his valve rim.
"What are you doing?"
Sentinel gave him an almost glare.
"Checking for damage you twit! I didn't want to hurt you, but if I did you can be sure I'll be taking you to the medic!"
Optimus shrank back and let Sentinel probe the tender metal flesh of his valve, ignoring the tiny bolts of pain that sudden movement caused.
A relieved vent from Sentinel told him all was fine. He snikked his panel closed as soon as the fingers cleared the rim and resolutely stared at the wall, embarrassment and shame flushing his dermal metal and making it hot to the touch.
"Look, it isn't that big a deal. Just, next time I'll be more careful. I don't want to hurt you, Optimus."
A quick glance showed him Sentinel's face was serious. Optimus pushed himself up and gingerly rested against the wall.
"Sorry, I really didn't know."
Sentinel crawled up and sat next to him, pulling him into a rough hug and staying with his arm wrapped around Optimus' shoulders.
"Just talk to me. I don't EVER want to hurt you."
~end flashback~
...
Sentinel's optics force booted as his processor snapped on. His vents were shaky as the last of the memory flux faded from his active thoughts and he stared into the face of his once best friend and lover.
Primus it was hard not to touch. His body remembered, achingly so, each touch and caress from the dream and his processor hurt to think on the conversation.
'I don't ever want to hurt you.'
Frag. He'd bungled that up spectacularly. How had it gone from perfect to slag so quickly? He'd really loved Optimus back then, Pit, he wasn't sure he didn't still love him, but…
It didn't matter now anyway. Optimus had made it clear where Sentinel stood with him.
...
The days started to pass more quickly. A rhythm was hammered out and followed; Sentinel even found that he was starting to enjoy playing with the twins. He couldn't remember playing like this with his own creators, and it was a soothing balm to the tension that was ever present between him and Optimus.
The first few days had been rough, but everything was new that it was almost expected. Once they tried to set up a third berth in the room for Optimus though the twins would have none of it. They were fine sleeping in Sentinel's berth or the extra one pushed against the wall, but they had fits if Sentinel and Optimus didn't sleep in the same berth.
It took some 'creative rearranging' on the two Prime's parts, but eventually the twins were satisfied and Optimus was accepting. Sentinel had firmly tamped down his almost gleeful reaction to the situation, his body shuddering in anticipation to something his processor shut down instantly.
Still, they were here and if not happy then at least satisfied with the whole arrangement.
Until that Primus dammed recharge flux anyway.
.
Optimus vented and pushed Sentinel off of him.
This had started happening more and more frequently and he was getting quite tired of it. Sentinel's cuddling ways were apparently no lesser now than they had been at the Academy but where Optimus had welcomed them then he pushed them away now.
A grunt came from the recharging bot, then a soft murmur that sounded suspiciously like 'Baby please' before the arm came reaching again to snug Optimus to the broad blue chest.
Optimus felt his patience fray and snap. He could have dealt with this if it wasn't a constant thing, but every single night he was clutched at and felt up and pulled into the softest and most tender embraces he'd had since the Academy and he just couldn't…
He just couldn't. He refused to fall into that trap again.
"SENTINEL!"
It wasn't just Sentinel that burst out of recharge and Optimus regretted his outburst immediately as the twins started to wail.
He shoved himself off the berth and sat down next to the jets, cooing softly and stroking their helms in motions that calmed him just as much as it calmed them.
Sentinel was looking at him in a dazedly confused way.
"What?"
Optimus just vented, resisting the urge to rub the edges of his optics.
