It was a natural thing, he supposed, and he wasn’t scheduled to work that day anyways. Still, the image of Reigen palming his dick through his slacks, reclined in his office chair, didn’t leave his mind. The second time had been when they were getting ready to infiltrate the all- girl’s school. Reigen was taking a long time getting dressed so Shigeo was left standing in the office, tugging at his skirt. After a few minutes had passed, Shigeo had went to the bathroom door, his hand raised to knock. But the faint sounds he could hear on the other side had his fist lowering and his ear pressing against the wood. Shigeo had been too scared to touch himself at the time, but when he got home that night he replayed the small gasps and whimpers again and again in his mind as he fisted his cock. After that night, Shigeo decided to act. He was under no delusions that it would be for his master’s sake, either. Reigen obviously needed some sort of intimate contact, and Shigeo couldn’t deny that the prospect was exciting. He lover his master after all, and thought to himself that having his first sexual experience with the man would be quite nice. He went to the office on one of his days off, hoping to catch Reigen replicating the scene from a few weeks earlier. Sure enough, when he cracked the door open Reigen had his hand down his pants and his head thrown back. Shigeo watched for a few moments before opening the door and stepping in. “Good afternoon, master.” Reigen moved lightning fast, his hand slipping out of his pants and his chair creaking upright in less than a second. “M-Mob!” His face was flushed and sweaty as he scooted his chair into his desk. “What are you—?” “I thought I could help out today, since my club activities were canceled.” Reigen crossed his legs, obviously trying to hide his erection. “I was just—” Reigen’s hands fluttered around for a second, and Shigeo could see that the one that had been down his pants was shining with some sort of lubricant. He put his hands on his keyboard, in lieu of having anything better to occupy them. “Working on a case. But I don’t think I’ll need any help.” Shigeo moved further into the room, standing in front of Reigen’s desk. “It didn’t look like you were working when I came in.” Reigen’s face took on a deeper sheen as his mouth opened and closed like a fish out of water a few times. Finally, he gave a sheepish grin. “Okay, you caught me. I was napping.” It was a good save, and if Shigeo hadn’t known better, he would have bought it. He had never attempted to flirt with—or seduce, for that matter— anyone in his life. He thought for a moment before recalling girls in movies who would lean over a desk to flaunt their cleavage. Shigeo of course had none, but hopefully the mood of the action would be read. He placed a hand down on Reigen’s small desk and leaned forward, so that he was effectively invading Reigen’s personal bubble. Reigen’s eyes widened but he didn’t pull back as their faces were brought close together. “I think you’re lying to me, shishou.” “I—” Reigen swallowed, his eyes never leaving Shigeo’s. “What are you doing, Mob?” Feeling a small pang of annoyance, Shigeo decided to try a different course of action. He was never one for subtleness anyways, so why should this situation be any different? He straightened up only to drop to the floor. Reigen’s chair wheels squeaked as he rolled back a few inches. “M-Mob--!” But he was already under Reigen’s small desk—really just a table that was glorified into a working space. He grabbed Reigen’s legs and tried to pull him closer, but Reigen rolled back more and bent in his chair to look at him. “What the hell are you doing, Mob?” “You were masturbating.” Reigen’s flushed face seemed to lose every ounce of color in a mere second. Shigeo grabbed at the man’s leg’s again, and with a swift pull had him substantially closer. “I saw you touching yourself, shishou.” Reigen straightened up so that Shigeo couldn’t see his face. “Get out from under there.” “I want to make you feel good.” He heard a choked noise from above him as he ran his small hands over Reigen’s tightly closed thighs. He could feel the lean muscle of them flex under his fingertips. “You don’t know what you’re saying, Mob.” “I do.” Shigeo placed his fingers between Reigen’s thighs and gently tried to pry them open. “Please…” An entire minute must have passed in silence as Shigeo waited patiently under the table. He wondered what Reigen’s face looked like right then. Slowly, cautiously, the thighs spread in front of him and he was greeted with the slight bulge of Reigen’s cock, the head outlined prettily against his leg and the fabric dark and damp around it. “Shishou…” Shigeo leaned forward and immediately mouthed at the bulge, his tongue probing at the squishiness of his master’s balls. “O-ohhhhh—”Reigen drew the exclamation out on a long, trembling exhale. Encouraged, Shigeo reached up and began clumsily unfastening Reigen’s trousers. He expected to have to pull down boxers, but was surprised when he saw Reigen’s sandy pubes as soon as the zipper was down. “No underwear, shishou?” He reached into Reigen’s slacks and pulled out his swollen cock, rubbing it lovingly between his hands. “Are you a pervert?” Reigen only let out a weak hum in response. It sounded muffled, and Shigeo could imagine Reigen biting into his hand to keep any excess sounds from escaping. He licked his lips before blowing a puff of air against the shining slit, pleased when the thighs around him tightened and shook. He reached down and palmed at his own erection as he stuck his tongue out and began licking the tip tentatively. Reigen cursed breathlessly above him as he wiggled his tongue over the salty head. “Shishou, I’m going to suck it now.” Shigeo’s hands left Reigen’s cock for a moment to unfasten his own pants and pull out his cock. He sighed and jacked himself off slowly as his free hand gripped the base of Reigen’s erection. “We have to hurry, in case a customer comes.” “Oh god…” Reigen’s chair shifted as he sat up straight, seeming to have forgotten where they were. “I should lock the door—” But Shigeo didn’t feel like waiting. He took the head into his mouth and gave a gentle suck, effectively cutting off Reigen’s train of thought. He worked slowly, methodically, alternating between suckling at the tip and licking along the sides. Reigen’s cock was so pretty, girthier than his own and just a little too much to take in all at once. Shigeo paid special attention to veins along the sides, thicker near the base. He didn’t know if kissing and licking at them felt particularly good to Reigen, but by the sounds above him, the older man wasn’t picky. “You taste really good, shishou.” Shigeo pulled away long enough to spit into his palm before he was back on Reigen’s cock, this time taking the head and a few inches of length into his mouth. He hollowed his cheeks out and began bobbing his head at a steady rhythm, moving his hand along his own cock at the same pace. It only took a few seconds after that for the muscles in Reigen’s legs to really begin spasming. The small whimpers from above him raised in pitch and the saltiness he could taste on the back of his tongue increased as well. Shigeo focused enough to leave his body just slightly, enough to continue his ministrations but also to float above the table and see Reigen’s face as he began to reach his orgasm. The split in consciousness somewhat dulled his own physical pleasure, but the sight of Reigen’s face, red and shining with sweat, his brow knit as if in pain, his knuckles white on the edge of his desk, had Shigeo’s own orgasm hitting him. Reigen groaned and threw his head back as his back curved from his chair and pulses of hot semen ran down Shigeo’s throat. He snapped back into his physical body and whined around the cock as he swallowed shot after shot of cum, his own dick jumping and twitching and spilling on the floor between his legs. “Fuck, Shigeo…” He heard a thud above him, assumedly Reigen’s head hitting the desk. The use of his first name had Shigeo sucking on Reigen’s cock again, wanting to milk him of everything he had to offer. When the two of them were left panting and drained, Shigeo tucked himself back into his pants before showing the same courtesy to his master. His knees were achy and his feet had fallen asleep, but he managed to crawl out from under the desk. Reigen looked him over, his cheeks still a bright red. “I made a mess on your floor, I’m sorry.” “That’s…” Reigen’s voice cracked. “That’s fine.” “I’ll see you after school tomorrow, shishou.” Reigen nodded. With a bounce in his step, Shigeo left the office. End Notes Shoutout to the patreon who requested some reimob!
