Kaoru leaned over the bath to turn the water on, the tub was easily big enough for the two of them and had powered jets like a Jacuzzi. He could spend all day in this bath.
He jumped when arms slid around his waist and Hikaru nuzzled his neck, they had the sex drive of rabbits and even though they had just gone a round, Hikaru could have just bent him over and done it all again. He sighed and leaned back into his brother, letting the hands roam his chest freely.
He yelped when the hand cheekily squeezed his semi-erect member and Hikaru leaned past him to stop the bath. The elder twin slid in first, moaning as the water soothed his muscles and the jets hit his sensitive skin like little shots of pleasure.
Kaoru watched his brother lean back and bit his lip, the sight was so enticing and he knew from experience that the jets, if angled right, could be absolutely magical.
He shook his head and got in so that his back was resting against his brother's chest. "I'm going to make you beg for me" Kaoru whimpered as Hikaru whispered into his ear, hands tweaking the pink nipples again, watching as Kaoru squirmed with delight.
Turning around, Kaoru ground their hips together and kissed his twin for everything he was worth. Tongues met in a fierce battle, and Hikaru sat back, letting Kaoru take the lead for once. He let his eyes slip closed as gentle lips kissed along his jaw and beneath his ear, where Kaoru knew his sensitive point was.
He felt his hair being wet, before Kaoru began to massage shampoo into the auburn hair. The feeling was so relaxing that Hikaru felt himself slip further into a state of bliss; after a few minutes the shampoo was washed out and as he opened his eyes to return the favour, he saw Kaoru grin and duck underneath the water.
His eyes widened in shock as a mouth closed around his erection under the water of the bath, the sight of a submerged Kaoru bobbing up and down was new to Hikaru.
The water acted as an extra lubricant and Kaoru worked his tongue along the vein on the underside of his twin's member. Pretty soon, he had to resurface for breath, his hair now wet enough for Hikaru to wash it.
A sloppy kiss was placed on Kaoru's lips and his efforts were rewarded with a scalp massage as he took his previous position against his brother's chest. Once the suds were washed out and their erections could no longer be ignored, Hikaru came up with an idea.
Hooking his hands under Kaoru's knees he lifted the legs high and told him to plant his feet on either side of the bath, spread eagle for his twin to play with.
A heavy blush adorned Kaoru's cheeks and Hikaru glanced darkly at his new position before reaching for the shower head that came as an accessory for the bath – normally used to wash hair.
"Close your eyes, keep your legs open" The order was laced with lust and Kaoru moaned but did as told, closing his eyes and letting his head loll back onto Hikaru's shoulder.
Hikaru smirked and turned the shower head on so that warm water was blasted out at a jet like speed and then before Kaoru could realise what was about to happen, he turned in to face him. Kaoru's eyes flew open when the burst of water hit his nether regions, tingling his erection and blasting his now quivering hole.
"Eyes closed Kao" A hand covered his eyes, only intensifying the feeling of the jet, which created a delicious friction that had him groaning and panting like a mess. He cried out when Hikaru focused the flow on the tip of his penis, the feeling so strong it was almost painful, but Kaoru didn't care.
"I'm going to cum, ngh" He breathed out, thrashing in his brother's arms but all too soon the jet was gone and his skin tingled with the left of sensations.
"Not without me, you're not" Hikaru chuckled, still covering his twin's eyes as his other hand tickled Kaoru's inner thigh, feeling it shake as Kaoru giggled.
Without any resistance, two fingers slid easily into Kaoru's still stretched entrance and curled, brushing the already sensitive prostate, until Kaoru begs him to stop.
Hikaru uncovered Kaoru's eyes and manoeuvred them so that Kaoru was resting his elbows on the edge of the bath, on his knees infront of Hikaru, who used the tub of scentless lotion they had as lubricant. Hands massaged the round globes, spreading them slightly as Hikaru brushed the twitching entrance with the tip of his penis.
Finally pushing in, there was no sense of patience as in their last round, this time was hard and rough and Kaoru was given no time to adjust to the intrusion.
The water sloshes as the thrusts grew in speed and strength, the sound of skin slapping resonating through the room. Both moaned and gasped as the friction sparked desire in the twins.
Hikaru leaned over his brother, moulding his chest to Kaoru's back and continued the thrusting, letting the younger one hold their weight up on shaky arms. Sliding an arm around to the front, Hikaru slowly squeezed and massaged his brother's erection, the speed difference driving him mad.
"Fuck" Hikaru groaned, knowing he was close, but by the tightening of Kaoru's insides, he knew he wasn't the only one. "Come for me" He purred, grinning when Kaoru's body quaked as his release spilled into the bath.
"Hika…" Hearing his name being moaned sent him over the edge and he bit into the shoulder that didn't already have a bite mark, successfully marking Kaoru as his own as he released inside of him.
Completely spent from the two releases, they washed the remnants off and slouched into their bed, snuggling close and falling asleep within minutes.
Kaoru would have fun explaining the bite marks to the host club the next day.
