“I have a favor to ask of you…”
Makima’s voice echoed through Denij’s mind as he opened his apartment door. The thought of her body was seared into his memory; the curves of her tits were visible through her thin white button-up shirt. She had crossed her arms and leaned toward him as she talked, as if she wanted him to see the way her breasts bulged forward. He had already felt one of them before, and now she proposed that if he defeated the Gun Devil, he could have sex with her. Blood rushed through his groin at the thought of her naked figure, usually so formidable in her business attire. The thought lingered as he kicked his shoes off and entered the apartment. Tonight, there will be a drinking party. An image of a drunk Makima now entered his mind, her face flushed and speech softened around the edges. What wonders did this evening hold?
“Hey, Aki, are you here?” Denji called as he entered the living room. His question was quickly answered at the sight of Aki sprawled out face-down surrounded by empty beer cans.
“What the fuck? I’ve been working all day today, where’s my meal, asshole?” Denji’s stomach rumbled. He went over to Aki and kicked him in the side. “Why are you just passed out like this? Get up, let’s go!”
Aki just groaned and shifted, showing no signs of waking. Irritation flared within Denji. He had been working hard all day, and this guy was just slacking off drinking by himself? So much for Denji being the loser, it’s time the tables were turned.
With one more shove, Aki flipped over onto his back. Somehow through all of the kicking, he still remained sound asleep. As he moved, his thin black undershirt pulled tight across his chest.
“...and I come home and you’re sound asleep and––” Denji stopped talking at the sight of Aki’s chest. The curves of his pecs formed a valley in between the fabric, the mounds of smooth muscle punctuated by hard nipples. Without his usual baggy clothing, he could see every dip and edge of his body. The kicking ceased and he dropped down into a squat beside Aki’s figure.
The muscles in his chest are so big, it’s almost like a woman’s. He reached out and traced a finger down the middle of his pecs, then retreated his hand as if he had been burned. Still, the feeling had been warm, and Denji’s body ached for that warmth, any warmth at all, so he reached his hand back out and touched Aki’s chest with the timidness of a lamb, then spread his fingers out and cupped underneath the swell of the muscular flesh. Aki let out a soft moan at his touch, shifting slightly but not waking.
What the hell am I doing? Every voice in Denji was screaming at him to stop, yet it was as if his hands were moving on his own, squeezing and massaging Aki’s chest with increasing intensity. He could feel Aki’s nipples hardening under his palms so he stopped massaging and circled his fingertip around one of them. The sensitive skin immediately reacted and stood up like a little tent. Denji gently pinched the two nipples between his fingers, prompting a slight whimper from Aki.
“You like this?” The question hung in the air unanswered, save for Denji’s own body. Blood rushed warm in his groin and his dick stiffened against his jeans. He withdrew his hand and sat there above Aki, his hand over his mouth, cheeks flushed and chest heaving.
But he’s a boy, this is wrong, he thought as he lifted Aki’s shirt. I’m saving my virginity for Makima, I’m only Makima’s, he thought as he unzipped his jeans. I’ll only rub it a little bit, just quickly, this doesn’t count, I’m still a virgin, he thought as he rubbed the tip of his penis against Aki’s right nipple, pre-cum leaving a dewy sheen on the delicate pink skin. Denji took a deep breath and put his dick between Aki’s pecs, using his hands to squeeze the muscles together on the sides of his shaft. Aki muttered something indiscernible but didn’t wake and Denji didn’t think that would matter anyways, the warmth of Aki’s body was addicting, his hips were moving now and there was no stopping him. His own pre-cum created a slippery surface to thrust in and every movement created a jolt of electricity that shot through his dick and into his pelvis.
Pressure was building inside his body. Aki’s chest felt incredible but he wanted more. Saliva pooled in Denji’s mouth at the thought of warm, slick wetness wrapped around his head and shaft. Clenching muscles sucking him deeper inside . . .
Denji stopped thrusting and turned his attention to the belt buckle fastened at Aki’s waist. It was difficult to unfasten it with his trembling hands––he kept glancing up at Aki’s sleepy face, wondering when his eyes would come flying open and land a punch right at Denji’s exposed crotch. The belt made a jingling sound as he pulled the pants down to Aki’s knees. Now there was just a pair of thin gray underwear before him. The outline of Aki’s soft dick could be clearly seen through the barely-there fabric. Denji grabbed at the waistband, tugged at it, hesitated, then pulled those down with a gulp. At last, exposed skin. To his great surprise, Aki remained asleep through all of this, even as Denji hoisted his knees upward to expose his asshole, even as he rubbed the tip of his penis against the puckered skin. The tender area flinched in response to the stimulation. Denji sucked in a breath at the sensation, then pushed.
The head of his penis slid inside easier than expected. Aki’s ass opened up to Denji and wrapped in blazing body heat around the tip. A gasp escaped Denji and his hips bucked with a sudden fervor.
Aki’s eyes flew open. Time stood still for that instant, Aki’s eyes changing from the languid syrup of drunkenness to an adrenalized clarity.
“What’s going on? What the hell is this?” His voice was still slurred. How much alcohol did the guy drink?
“Good morning sleepy,” Denji moaned, his thoughts preoccupied with the spasms occurring around his dick from the moment Aki woke up. “Aki, do you have experience? This was easier than I thought it would be.”
“I don’t have fucking experience, what the fuck Denji. Pull out immediately!” Aki’s tone had turned to a fever pitch. This voice was typically the harbinger of fear, and yet Denji only felt a mad adrenaline pumping through his blood.
“Oh, so you can’t shove me off? In that case, let me just move around inside about three times or so, then I’ll be–” Denji’s sentence was cut off by a fist landing squarely in his jaw. Red flares of pain shot through his face. He stared down at Aki in a mask of fury. “What the fuck?”
“Don’t ‘what the fuck’ me! Get off me now!” Aki shrieked. He flexed his torso as if to shoot upwards and shove Denji off, then slumped back to the ground. “I’m too drunk. I don’t have the strength in my body.” His words slurred together into a blur of syllables. Sweat beaded from Denji’s pores as adrenaline and fear mixed together in an intoxicating rush.
“When you move like that, I feel you clenching around me,” Denji whispered, his voice low. “I can’t pull out.”
“Haven’t you had enough?” Aki shouted. His shirt was disheveled to his neck, the large muscles of his pecs forming shapes that could almost be mistaken as breasts. Denji grabbed Aki’s hips and shifted him up onto him, his hands kneading into the soft flesh of his ass.
“This is such a lewd outfit, I can’t resist. I’m going to put it all the way in just for a moment.”
“Don’t call my outfit lew––” Aki cut himself off with a shriek as Denji bucked into him. Now the blazing heat of Aki’s body was completely surrounding Denji’s shaft and he couldn’t get enough, his hips were moving on his own. Every thrust into the tight, slippery passage sent bolts of ecstacy deep into his groin. Aki’s furious cries were intertwined with softer peals of what could be moaning, infused with pain bordering on pleasure. Denji looked down at his agonized face as he thrusted, bending down towards his torso.
“What is that voice coming out of you? Do you enjoy this?” His own voice shuddered as he spoke, his focus strained with holding back against the mounting pressure in his body.
“Fuck off, get off me! I hate this! I hate you!” Even as he said this, his voice betrayed him when Denji hit a spot deep in his body. Aki’s body convulsed with unwanted pleasure and he gritted his teeth to stop himself from moaning. He put his hands up to push at Denji only to have them pinned to his side. Denji leaned in close to his face.
“When you struggle, it makes your ass tighten around my dick and it feels incredible. Struggle more, please.” He picked up the pace, the room filled with the sound of skin slapping against skin. Every stroke felt like heaven deep in the depths of Aki’s body. He leaned down and pressed his lips against Aki’s, whose cry was muffled in his mouth. His tongue slipped inside before Aki could resist. The air between them was hot as Denji pulled back and looked down at him.
“I’m about to cum,” he gasped. The pressure was unbearable––he could feel his body readying like a piston, his muscles wound tight in the delicious ledge that occurs before tipping into orgasm. Aki battered at his face and body with his hands but he was too weak and completely unable to stop the force that Denji possessed in that moment.
“I’ll kill you if you cum in me, you’re dead,” Aki hissed.
“I’m sorry, I can’t stop, I can’t.” Even though he’s a guy, I can’t stop. There’s no way I can stop. God, it’s Aki, I’m going to cum in Aki’s ass––
It was as if he was struck by lightning, his body tipping past the breaking point in a thunderous crash. Liquid surrounded his dick inside the tight orifice as he came. He could feel Aki’s body taking it in, clenching and shifting around him. His body gave out from underneath him and he collapsed next to Aki, who was unresponsive. Silence set upon the room like a vice choking the both of them. How were either of them supposed to move now?
But it felt so good…massaging his chest, kissing him, pushing my dick inside. Is this what sex is like? Denji looked down at Aki’s still form. It was impossible to tell whether he had fallen back asleep or refused to turn and look at Denji; he didn’t want to find out. He got up and put a blanket over him.
Sex with someone you love . . .
