Chapter Text
“Are you doing alright, darling?”
“Y-Yes…” Alphamon gasped.
When the other Royal Knights had insisted that he and Omnimon go on vacation, somehow, Alphamon doubted that this was how they’d thought he’d spend it. Omnimon was sitting up against the headboard of the bed in the suite they’d rented for the week. He was still wearing most of his armor, but for the armor around his hips and groin and his large WarGreymon and MetalGarurumon gauntlets. The black undersuit he wore beneath had been zipped open, freeing his long, meaty cock.
Alphamon, in comparison, was almost completely naked; only his helmet remained in place. He was straddling Omnimon’s hips, slowly lowering himself onto the other knight’s dick. Omnimon had one hand on Alphamon’s waist while the other cupped his helmet. Alphamon’s arms were stuck in leather sleeves and folded behind his back. The sleeves were laced together with sturdy rope, binding Alphamon’s arms. More ropes were wrapped around his biceps and chest, framing his plump pectorals. A crisscrossing net of rope weaved down his torso, ending by firmly wrapping itself around Alphamon’s erect cock and balls.
“D-Damn it all…” Alphamon swore as another inch of Omnimon’s dick slid into his hole. “Why is your cock so big?”
“Do you need to stop?” Omnimon asked in concern.
“No!” Alphamon said defiantly “I-I’ve taken it before and I will take it again!”
After a moment, Omnimon nodded, the hand on Alphamon’s waist gently massaging circles into the muscle there. “Remember to take it slow, love.”
Alphamon nodded and shuddered as more of Omnimon’s ginormous length slid into his stretched-out hole. Omnimon’s huge girth was the reason the white knight was usually the one on the receiving end when they had anal sex. Alphamon also wasn’t normally the one tied up either, but Omnimon had asked if he could dom this time, and Omnimon asked to switch roles so rarely that Alphamon had never been able to refuse his lover when he did. It had taken a lot of lube and preparation to get Alphamon’s hole loose enough, and the black knight still felt like he was gonna split in two at any moment.
Alphamon had lost track of how far down he was on Omnimon’s cock, so when he finally felt Omnimon fully hilt inside of him, he almost cried in relief. Omnimon pulled Alphamon’s helmeted head down until their foreheads were touching. “How do you feel, love?” Omnimon asked.
“F-Full…” Alphamon gasped “F-Fuck Omni… I forgot how big you are…”
“Flatterer.” Omnimon chuckled, stroking Alphamon’s cheek. “You’re doing so well, love.”
“O-Omni…” Alphamon whimpered.
“Are you ready?” Omnimon asked.
“Yes… please.”
Omnimon’s eyes crinkled in a smile. “As you wish.”
With that, Omnimon slowly started to rock up into Alphamon, sliding his thick cock in and out of the black knight’s stretched ass. Alphamon cried out as the head of Omnimon’s cock rubbed against his prostate. He rocked back to meet Omnimon’s movements, chasing the pleasure. Before too long, the two knights had settled into a steady rhythm. Alphamon found himself staring into the clear blue pools of Omnimon’s eyes, the depth of affection shining within them sending lightning shooting up Alphamon’s back that had nothing to do with the cock plowing his ass.
“I love you.” Omnimon said, nuzzling his helmet against Alphamon’s and briefly pressing their faceplates together in a facsimile of a kiss.
“Ah, I-I love y— AH FUCK!” Alphamon’s declaration was derailed by the wonderful pleasure coming from his ass.
Omnimon chuckled, “I know, dear.” and with that, he increased the pace of his thrusts, and Alphamon was lost.
Alphamon clenched his eyes shut from the pleasure. The sensation of Omnimon’s thick cock spreading him open and hitting all the right places inside of him, it made his cock throb against the ropes wrapped around it. Omnimon may not top very often, but Alphamon would be remiss to pretend that he wasn’t damn good at it.
Omnimon’s hand strayed from Alphamon’s helmet, sliding down to firmly grip the black knight’s cock. “Do you want to come, love?” he asked sweetly.
“P-Pl-Please!” Alphamon begged.
Omnimon started to jerk Alphamon off without another word, and it was too much. Combined with the pleasure from his ass, Alphamon’s fragile control was shattered and he found himself slipping towards his limit.
“Ahh! O-Omnimon!” was all the warning Alphamon could give before he came undone.
“That’s it…” Omnimon soothed “Come for me, love.”
Alphamon did. His cock twitched in Omnimon’s grasp, and the first shot of the black knight’s orgasm spurt into the air, arcing down to splatter onto Omnimon’s breastplate. The white knight continued his ministrations, milking out the next blast of semen from Alphamon’s orgasm, which painted Omnimon’s abdomen. The third and final load of Alphamon’s ejaculate dribbled out of the black knight’s cock, dripping down the head and over Omnimon’s fist. Alphamon trembled from the force of his orgasm, a heady bliss filling his head.
Omnimon’s thrusts came to a stop, and the white knight started to withdraw. As Omnimon slowly pulled his cock out of Alphamon’s ass, the leader of the Royal Knights realized something. “Omni… you… you didn’t…” Alphamon was too exhausted to finish his sentence.
Omnimon shook his head, stroking Alphamon’s cheek “Tonight’s all about you, love.”
“Omnimon…” Alphamon sighed, gazing into his lover’s shining blue eyes. He wanted to argue, but he didn’t have any strength left. When Omnimon’s cock was fully out, he pulled Alphamon down to rest on his chest. Alphamon sighed in contentment, nuzzling his face into Omnimon’s neck while the other Digimon gently stroked his helmet.
“Do you want me to untie you?” Omnimon asked softly.
Alphamon shook his head. “No… please just… just hold me for a while…”
“Of course, darling.” Omnimon whispered, tightening his grip around his lover.
Exhausted, Alphamon felt his eyes start to droop shut, and before he knew it, he was sound asleep in Omnimon’s arms.
