Darth Vader sat back in the chair, polished helmet reflecting the plain light in the chamber as Obi-Wan kneeled before him. The suit components protecting all his vital systems were in place, imposing and obsidian, creating a fearsome and intimidating visage for his old master to look upon.
Protruding from between Vader’s legs was a thick strap-on dildo. The silicone material was black and shiny, not dissimilar to his helmet. It stretched upwards from the strap in several thick inches, the head weighed down by its own girth. Underneath the shaft of the strap-on were two black silicone balls, modeled to look as human as possible.
It was extremely hushed in the chamber besides the signature mechanical hiss from Vader’s breathing apparatus. Beckoning his old master, Vader gestured him over. Behind the visor on his helmet, his eyes ran over Obi-Wan’s revealed naked body as he crossed the room towards him. Vader loved to watch Obi-Wan’s vulnerable naked form; every inch of him was so human and delicious, and he knew that every inch of Obi-Wan was his alone.
Vader gathered Obi-Wan’s hands in his own, gloves squeaking in the quiet room, and guided Obi-Wan to turn around so that he stood with his back facing him, legs on either side of Vader’s.
“Spread your pretty hole for me, my pet.” His voice, a synthesized growl, was not his own, but a metallic echo of his former self, an unnatural sound that of a monstrous machine.
Vader dipped his fingers into the small vessel of lubricant on the table beside him. He spread it around his gloved appendages until they were slippery and wet.
Obi-Wan obeyed his new Master, reaching behind himself and grasping on his buttocks. He spread them apart and exposed his puckered anus to the cool air and Vader’s gaze. The Force suppression cuffs on his wrists were the only things Obi-Wan was permitted to wear here.
Vader reached forward and pressed the pads of two lubed fingers against his hole, running them around the entrance in a slow circle. He wanted to brutalize his pet, to make him suffer with the same cybernetic limbs that caused him daily unending pain, but he controlled the morbid instinct. Keeping Obi-Wan alive and tormented by regret and pleasure would be more effective.
Vader slowly slid his fingers into him, pushing past the tight muscles at the rim of his opening. Obi-Wan’s strong thighs contracted at the penetration and Vader watched his muscles ripple underneath warm skin. With his other hand, Vader reached around Obi-Wan and cupped and fondled his testicles. His pet had not cum for several days and his testicles were hot and heavy, full of unspent seed.
Vader thrusted his black fingers inside of Obi-Wan for several minutes, thoroughly lubricating it and stretching it around the girth of his gloves. Obi-Wan knew better than to make any noise and was quiet as his captor molested his body. Eventually satisfied that Obi-Wan’s bottom was prepared, Vader withdrew his fingers from his hole with a small twist against the man’s prostate, causing Obi-Wan to stumble slightly, body too sensitive to Darth Vader's touch.
Vader tugged softly on Obi-Wan’s balls and he moaned softly against his wishes. Vader squeezed intensely using his cybernetic grip, not speaking but threatening his pet with a gelding if he did not keep his noises to himself. Obi-Wan cried when he could not moan, and that was what Vader craved to see most of all; his old master choked up and breaking down as he falls apart on Vader’s stabbing black dick.
Vader loosened his hold on Obi-Wan’s testicles but did not release them, using them to pull him back into his lap. Vader wrapped his gloved hands around Obi-Wan’s thick hips and lowered them down to his waiting cock. His pet’s pussy was used to being fucked daily and it opened easily around the head of the strap-on, black silicone breaching his pretty hole. Vader slid his shaft deeply inside of Obi-Wan. He pulled his hips back until his ass was flush on Vader’s clothed lap.
Obi-Wan leaned back into him, twisting his head so he could hungrily kiss at Vader’s mask. His tongue dragged over the surface of the smooth durasteel and Vader sat there, accepting the sick display of affection.
Vader slipped his fingers between Obi-Wan’s cheeks and traced his fingertips over the rim of his stretched pussy. Obi-Wan exhaled roughly. Vader cupped his old master’s firm butt and lifted him up in his lap, commanding, “Pleasure my cock, pet.”
Obi-Wan moved his ass up and down the thick glistening black shaft inside him. Vader guided his hips to help him rock on him, ensuring he inserted the entire length of the strap-on. Obi-Wan was hard as he rode Vader, cock bouncing against his own belly as he fucked himself.
“Only when you have my permission may you cum,” Vader spoke in a hissing tone in his ear.
“Yes Master, thank you Master, “Obi-Wan panted as he increased his rhythm, rocking his hips back even harder. The famed Obi-Wan Kenobi; bouncing on Sith cock and calling Darth Vader his Master.
Obi-Wan’s ass gripped tightly around the strap on and sweat coated his hairy thighs. Vader’s hands went around him and massaged his balls, ignoring his shaft entirely. Obi-Wan’s cock was an afterthought in these sessions. The first and principal focus was Vader’s strap.
“I live to make you happy, Darth Vader, my Master,” Obi-Wan moaned as his hips drove the strap-on deeper inside him.
Vader felt a deep satisfaction at Obi-Wan’s profession. He could sense that Obi-Wan’s orgasm was starting to build up and grabbed onto Obi-Wan’s hips tightly to pull him even harder into his thrusts. Obi-Wan’s thighs slammed into his own as Vader filled his pet’s hungry pussy.
Vader wanted to see his pet cum for him. Obi-Wan ground his hips down on his cock, circling them as he panted in the cool air. Vader looked down his strong body, at the gentle curve of his back and his spread working buttocks, his beautiful pussy clenching around his shaft, the wristcuffs a constant reminder that Obi-Wan belonged to him.
Vader let Obi-Wan work himself into a frenzy, rocking back and forth on the strap-on as his cock remained painfully stiff in front of him. Vader could manipulate his body like no other could. As he sensed Obi-Wan was about to cum, Vader stood up from his seat and bent Obi-Wan over it so that his pert rear was facing him.
He pressed his hips forward, strap-on sinking deep into his pet’s wanting hole. Obi-Wan held onto the chair and gasped as Vader began fucking him hard and deep. Vader lorded over him from behind and gave him permission to cum only when he heard the soft sound of tearful overwhelmed sobs in front of him.
“Cum for me, pet! Cum for your Master!”
Obi-Wan came without any hands on his cock, spurting all over the seat that Vader had been occupying. His ass was full of strap and Vader knew that Obi-Wan had always craved him in this way, craved Anakin. Vader fucked his black cock inside Obi-Wan until every last drop of cum had leaked out of him and continued even after.
Only when Vader had truly had his fill did he slide his strap-on out of Obi-Wan, leaving his anus empty and gaping wide. It glistened between his round buttocks. Knowing what was expected, Obi-Wan turned around and put his mouth around Vader’s cock. Obi-Wan looked up at Vader’s mask, and in his eyes, Vader saw his reflection.
