Summary - While Yukio is away on a mission, Rin gets a late night visitor.


Rin lay on his bed reading a new manga. His legs swung in the air behind him while his tail lazily swayed above him. Yukio was out on a mission that he had forbidden his older twin to follow him to, and so, he was alone for the night. He didn't mind, he was used to it. But that didn't mean that he didn't get lonely.

Sighing, he flipped the page over and continued reading.

He awoke up to the sound of loud knocks on his bedroom door, not knowing when he'd fallen asleep, but sure that the dream he'd been having was a good one.

Grumbling, he shuffled across the carpet in a daze and opened the door. It took him a moment to register the large, well-built blonde-brunette glaring down his nose at him.

"Well?" he growled.

Rin yawned and scratched the back of his head as he let the other teen in. His sight was still a little fuzzy as he closed the door and turned to see Bon sitting on his bed staring at him.

Dragging his feet back to his bed, he squeaked as he was harshly pulled forward. Straddling his rival's lap, he placed his slim hands on the teen's broad shoulders. "I'm really tired Bon, can we not tonight?" he asked as he rested his forehead against the others.

"If you're not in the mood, then I'll get you in the mood," the annoyed tone in his voice made the demon pull his head away. He looked into dark eyes with a confused expression. Rin opened his mouth to speak when a large hand caught the end of his tail a little too gently.

The light touch made the demon gasp and a faint blush spread over his pale face.

"That's unfair," he breathed as the hand rubbed his fur softly. Bon smirked as the others breath came in short pants. He then began to unconsciously grind against the crotch under him.

"It's the first night I've not had to sneak out of my dorm since last month," the blonde-brunette explained before letting out a growl as Rin's claws dug into his shoulders. "And you're already like this now, so why stop?"

The demon leaned his head onto his lovers shoulder as a hand crept under his night shirt and found his nipple.

"You bast-ahhhh-rd" he whined when a mouth latched onto his neck and began to suck. The blonde-brunette continued to play and mark as the demon started tugging impatiently at his belt.

Bon pulled back as his rival climbed off his lap and hurriedly pulled off all of his clothes. He was then pushed onto his back and stripped of his own trousers and underwear. A smirk swept over his face as he saw the bottle of lotion in his lovers hand when he returned to sitting on his crotch.

Rin leaned down and roughly crashed his lips to Bon's in a needy, heated kiss. He moaned into it as a hand wrapped around his tail gently.

Feeling a tongue lick his bottom lip, he opened his mouth up and let the wet muscle dominate. The blonde-brunette groaned into the fierce kiss as his lover started to grind against his naked groin.

With one hand wrapped around the tail, the other trailed around the demons hips and pinched the thick base of the appendage.

Rin pulled out of the suffocating lip-lock to let out a long, loud moan. "Bon... p-please..." he managed to gasp between deep breathes. His lover knew exactly what he wanted.

Removing his hand from the furry end of the black tail, he held his hand open for the demon to see.

With a struggle, he lifted his hand off of his lover's broad shoulders and flipped the lid of the lotion. He refused to stop grinding the body under him as he poured some cream onto the open hand. Carelessly dropping the bottle onto the bed, he started to spread the lotion.

Bon smirked as he placed his now soft hands back onto his shoulders. Moving his lotioned hands between their groins, he found the tight opening hidden between firm cheeks at once. Rubbing the thick liquid around the ring of muscle; he enjoyed the delicious moans he received.

"S-stop... ahhhh... teasing..." the demon whined.

Bon pushed in a finger just as Rin leaned down to capture his lips again. He swallowed the pleasured sounds as he added another slick finger and began a scissoring motion. The demon moved his rear in time with the slow movements of the digits inside him. He lifted his face away from the other teens and panted for breath when a third finger entered him.

"Play with your tail," the blonde-brunette breathed heavily. He lightly pushed his nails into the appendage and pulled them along the entire length.

Rin let out a pleasured shriek before bracing himself with one hand on his rival's clothed chest. While he massaged the base of his tail, Bon stroked the furry end. It was too much pleasure for him to handle at that point.

"Bon... y-you... now... ahhh!" he cried out. The blonde-brunette smiled as he let go of the fur and reached for the bottle of lotion. The demon helped to spread the cream over his throbbing erection with some difficulty.

He was also too impatient for his lover's approval.

As soon as the other teen's hand was reaching for his tail again, he slammed himself down. They both screamed and after several short seconds, he began to lift himself up and drop back down.

The two were moaning and panting at the hard rhythm the demon had set not long after he had started it.

Bon's large hands tightened on his rival's hips as he helped him rise and fall. His thrusts met every land and buried himself deeper inside with each one.

When Rin threw his head back and let out a loud, pleasured scream, he aimed solely for that spot. The demon let go of his tail to put his hands on his rival's chest again to keep himself steady. Every time his prostate was hit, he felt his knees weakened a little more.

Bon watched the demon intently. He made such a beautiful scene that he'd engraved into is memory many months ago.

With half lidded, lust glazed blue eyes staring down at him, he felt himself grow incredibly harder. His mouth hung open slightly to let out long, delicious moans with saliva escaping around his fangs and down his chin. A dark scattering of pink covered his face as he was completely lost in pleasure.

The muscles around Bon's length tightened as his lover released over his shirt that hadn't yet been taken off. Seconds later, he released inside the demon.

Rin sighed happily as he collapsed onto the firm, sticky chest under him. "I still hate you," he breathed.

"After nearly a year, and that's still the thing you tell me after every time?" the blonde-brunette chuckled. Lifting his rival's bottom half up, he pulled out and let him rest on top of him again.

One hand rested on soft black hair as the other threaded their fingers together. Like that, he drifted off to sleep like his lover had already done.

Rin wasn't surprised to find himself alone in his bedroom when he woke up. But he did find it strange that he was wearing a school shirt that was much too large for him. It also had a stain going down that front that looked all too familiar.

The demon paled as the answer hit him.

"He left me with his shirt because I got it dirty..." he mumbled. He felt numb as he remembered that Yukio had nearly found out about them when it had happened before.

His head rested between slim hands as he tried this hardest to think of how he was going to return the shirt back to his rival. Mostly because last time he couldn't do anything but throw it away, which, Bon hadn't been too happy about.

Rin's head snapped up as his bedroom door opened. All remaining colour in his face vanished as his younger twin stepped into view and looked straight at him.

"Oh shit," he said with a nervous laugh.
