A request from CelestialLight1117. It was much better in my head. Oh well.
Just as Shepard walked into his room, Grunt shoved him against the wall, knocking the wind out of him. The Krogan thrusts his tongue into the commander's mouth, barely fitting inside, hands wandering down onto his ass.
Shepard is hard when Grunt breaks the kiss, spit trailing from their lips. Grunt released the commander to let him fumble out of his clothes, the Krogan slipping off his armor with ease.
Staring at the cock unfolding in front of him, Shepard stopped pulling his pants down, shocked. Garrus wasn't kidding when he said Krogans had four balls.
Grunt notices his surprise and chuckles, holding up his half-hard dick to admire it passively. Shepard gulps and finishes pulling off his pants.
Before he is able to fight back, Grunt grabs John, bends him over, and thrusts himself inside of the other man, who lets out a cry of both pain and pleasure.
Grunt begins to hump quickly, in hard thrusts that rattle Shepard's bones. Under his breath, the Krogan murmurs something about the commander's tightness and how little hair he seems to have.
Shepard fights for consciousness as he feels his inside fill with Grunt's cum, letting out a raspy gasp of relief when the Krogan finally slid his cock out.
"I have proved my worth to you. Now, it is your turn."
Grabbing at a stim on a table next to him and piercing his leg with it, Shepard looks up to see Grunt bent over, waiting for him to do as he pleased.
With renewed energy, Shepard grabs Grunt by his hips, forcing himself in as deep as possible. The Krogan lets out a growl and flexes his ass around Shepard, almost enabling him from being able to move.
They synchronize each hurried thrust and paralyzing flex and it is not long before Shepard comes inside of the Krogan, letting out a wordless scream.
The stim had long worn off, and, in his exhaustion, Shepard fainted, hitting the ground with a thump. When he wakes up, he would find himself in the Med Bay, shivering despite being under an avalanche of blankets.
Mordin would hover over him, confounded. He will look Shepard in the eye, wink, and walk away.
This crew was a confusing bunch, he would think to himself as he lost consciousness once more.
