This prompt is all kinds of magical.
“Shit, Kaidan, I’m gonna co-” famous last words. Before he could finish his sentence or even his orgasm, he heard the crackle of biotics and then felt the tingling vise of restraints around his dick and balls, clamping down tightly and warding off his big finish with the sudden shock of pain that quickly faded to an aching need. His head fell back against the pillows and his jaw muscles clenched. “Kaidan, fuck, what…”
His eyes slammed shut as his over-sensitive skin was teased increasingly by his lover’s hot breath and lips. A gravelly voice spoke low right into his ear. “I’m not ready for it to be over just yet. This is the first time we’ve been able to do this without having to worry about another mission or saving the galaxy. We’ve got all night. And all day if it suits us.”
That made Shepard groan with a mixture of lust and frustration as he pushed himself up on his elbows and overbalanced Kaidan so he toppled onto his side and the biotic restraint faded away. Kaidan tipped his chin forward for a kiss, but Shepard was feeling a bit mean, so instead of giving his lover what he wanted, he shoved himself down on the mattress until his lips were even with Kaidan’s erection. The biotic’s hips thrust forward, but Shepard saw it coming, jerking his head back so that Kaidan’s effort only met air. “Relax and let me,” he said with a deep note of promise. Kaidan relaxed immediately and Shepard rewarded him by kissing the head of his cock before opening his mouth and throat, swallowing the biotic’s length fully and tortuously slow.
Kaidan curled forward convulsively into the fetal position, his top leg slipping up around Shepard’s back. The commander didn’t touch Kaidan any further than to move his mouth and tongue in strokes so calm and languid that it took Kaidan less than a minute to start trembling all over. It had never been like this before. Neither of them had ever had the leisure to focus completely and only on the pleasure and intensity that they could generate between them. And that’s why, when Kaidan’s hands clenched against Shepard’s skull and tangled in his hair, he didn’t mind at all that the commander saw it as a sign to swallow him deeply just one more time before slowly pulling back and releasing his cock right before almost, almost hitting the edge.
And nearly a half and hour later they were playing the same game over and over. They’d long lost count of how many times release had been just a hair’s breadth away. And they’d both learned quickly which touches and caresses soothed and which ones pushed them closer to what they both wanted. So here they were now, Shepard soaked in sweat and his skin flushed almost to burning. The sheets were damp with their strain and even the ceiling fan had given up hope of cooling him off. He thought his molars might crack with the pressure of clenching so tightly. And he knew, knew that he’d finally reached his absolute limit. Kaidan’s biotics were driving him wild enough that he thought he might go crazy if they kept on. So, he finally gave in. Clawed his fingers into the grooves of Kaidan’s shoulder blades and begged. “Kaidan, goddamn, please. I’ve got to. I’ve got to.”
A sigh of what might have been relief hissed through Kaidan’s teeth as he bent down and sealed their lips in a searing kiss, at the same time, angling his hips so that he could slide his lubed dick into Shepard’s well-primed entrance. Every muscle in Shepard’s body went taught and he arched his neck on a low growl, yanking helplessly at Kaidan to bring him as close as possible. And then began the dance they knew oh, so well. It wasn’t sensual and it wasn’t pretty by any stretch of the imagination. Kaidan pumped into Shepard hard and mercilessly, his moans growing to shouts and Shepard digging in and thrusting up as fiercely as he could. It was over in a flash. Both of them coming within seconds of each other with mirrored curses, Shepard’s back bowing up and Kaidan meeting him as he always did before pulling out as he came, messing the sheets and his lover’s tanned skin.
The next morning they woke to cold sheets and a sticky mess. Kaidan’s face was creased with marks from Shepard’s arm and being pressed down onto the pillow. Shepard himself woke with a dead arm and a light groan as they peeled apart. “Gross,” he said, his voice rough with sleep.
“Worth it,” Kaidan countered as he flopped onto his back and waited for his body to wake up enough to get him to the shower.
“Definitely,” Shepard said.
