The position reminded Kaoru of when Hikaru shot off his sled and squashed him while making snow angels in Osaka. Except instead of lumps of snow, in its place were ordinary bathroom items that had fallen from the sink, like toothbrushes and floss and soap. And instead of the crushing weight of the sled Kaoru had suffered through tears to have removed was another aunt on top of his aunt, with Auntie Kimi on the bottom, but not looking like she was crying or in pain. In fact, she probably liked that her twin sister Auntie Miku was lying down on her.
Through careful movements and bated breath, Kaoru was able to see why this was so. Through the opaque green plastic of the shower curtain he could see his Aunt Miku's hand was gone—lost in the folds of his Aunt Kimi's shining and blissfully wet lips. Squiggling like worms, Kaoru thought, eight-years-old and too young to even know what intercourse was, incest no less, thank heavens. Fascinating though it was, Kaoru silently prayed to whoever was watching his pathetic predicament for a quick release from the crick growing in his neck and the numbness beginning in his toes. He regretted having chosen the bathtub for hide-and-seek, but not as much as he regretted his heedlessness of Aunt Miku's advice as they were rummaging upstairs for places to hide. Honestly, how was he supposed to know they were searching for a spare room?
"Onii...Onii-chan…" he heard one of his Aunts breathe. By this time, their ecstasy levels were so ramped up, that he couldn't tell whose moaning voice belonged to whom. There came a squeal, then another moan. Kaoru dared himself to look again through the curtain.
"Ki-Kimi-chan, relax…you're too tight, Kimi, nnn…too fucking tight, I love it."
Kaoru blushed as he heard this, and covered his ears. They were making him feel strange—a mixture of disgust and…whatever that other thing is…and he didn't want to think about what they were doing. Even through his makeshift earplugs, a series of whimpers, followed by a peal of sexual euphoria, blasted in his ears. Their movements, from what Kaoru had eventually forced his virgin little eyes to see through his sliver in the curtain, were getting rampant and wanton. The scrape of flesh and nails against cold floor filled the bathroom. Squishing sounds and the dull thump of one exhausted body from another seemed to conclude the deed, and Kaoru was only too grateful that it was over. It was wonder that no one milling about the buffet table in the backyard had heard them.
"How about we take a shower before heading outside?" A manicured hand gripped a wad of curtain questioningly, almost constricting Kaoru's throat as she said this. He'd be fucking screwed to the ends of hell should they find him.
Over the rustling of clothes he heard his Aunt Miku say, "Don't you think that'd look too suspicious? As if it were enough that we've been gone for a while. I mean, if we both showed up with sopping wet hair..."
Kaoru relaxed as the hand eased its hold on his only means of safety. "The make-up too. That's a real bitch to put on. Anyway, the cake's gonna be cut in less than an hour; I doubt we'd be able to hide that."
The door unlocked, and, still on the subject of hair treatment and the expensive cost nowadays to have a perm done, the twins stalked out, the door ajar and their every article of designer clothing intact for the celebration outside.
"'Bout time that was finished," Kaoru muttered, face still hot and jeans still inexplicably tight. Wondering why that was, he let it go and stumbled on to the bathroom rug, every last thing that had been knocked over now stowed neatly away. The only proof of their debauchery was slowly wafting out the window, the musky smell of sex and taboo halfway gone. "And Hikaru... I almost forgot, he must still be looking for me." Kaoru smiled at the memory of their forgotten game.
There suddenly came Hikaru's voice, from the very back of the bathroom. It nearly made Kaoru jump out of his shorts. "Found you, Kaoru! Back here, back here!" The elder Hitachiin was wedged between the pile of dirty laundry in the hamper, a plastic basin over his head, and his eyes positively beaming at the reaction he had elicited, had witnessed, from his younger brother.
Moving forward and casting the basin aside, Kaoru asked him where he'd been. "You told me that I was the one hiding. You were the one supposed to be counting."
Hikaru accepted his twin's hand and climbed out of his hiding spot. "It's not like I expected Aunt Miku and Kimi to be coming here. We saw them at the steps, remember? Or did you forget that little show you watched in the tub?"
Kaoru blushed. And Hikaru cackled.
"I saw you. I saw you blushing and covering your eyes and ears and enjoying it!"
It was surreal that his brother regarded the entire matter like cartoon episode off TV. "Do they...do that often?" Kaoru asked softly.
"Mostly when they babysit for us. Maybe while they're babysitting for other people, too. A few times I've heard them, but I actually saw they once while getting out of bed while you were asleep." Hikaru scrunched up his face in thought. "At first I was scared but I watched a while and went back to bed when they thought there was something in the living room." He seemed to be lost in a sea of nostalgia and Kaoru could only gape like a petrified guppie.
"You enjoyed that?"
"You say it like it's a bad thing," Hikaru replied defensively. "But it did feel kind of good to see. You felt it a few minutes ago, didn't you?"
"Well...," Kaoru began. He didn't finish. As his brother inched closer, he felt his throat grow dry like it had dabbed with cotton. It was a familiar approach by now, one he'd seen with his aunts what felt like mere moments ago. Hikaru placed his hands softly on Kaoru's belly, sliding them down to the button of Kaoru's trousers.
"You still have it. That weird tightness down there." Hikaru's voice had lowered, his hand already on the fleshy bulge in Kaoru's trousers. It gave him a sadistic sort of pleasure to hear Kaoru's sharp intake of air as his fingertips had delved so far down. "You're actually really dirty for a goody-two-shoes, Kaoru. See? You're wet." His fingers eagerly accentuated this remark by taking a glob of fluid and rubbing it down in long, painstakingly slow circles over the head of Kaoru's arousal. This time Kaoru moaned, and Hikaru grinned to hear that he had nearly netted his prey.
"Hikaru, please stop. Just let's go outside and." His voice caught in his throat, fingers latching themselves on Hikaru's arm like a barnacle as the fingers feasted themselves on all the places that Hikaru learned from experimenting with himself would stimulate his nerves into jangling mass of silly string. Mid-beg and mouth agape so that his lips brushed against Hikaru's cheek, Kaoru struggled to keep his pants to a minimum and his whimper under wraps. "This...ahh...th-this isn't right."
Grimacing, Hikaru released his hold and looked Kaoru dead-on to show him how earnest he was. "No one knows what's right, Kaoru. And I know why you feel bad, but then again what's wrong with doing this with someone you love? Any other person wouldn't love you for you are as much as me. It's only us that matters, Kaoru."
Well, he wasn't wrong.
No one said anything for a while, though, until Kaoru tentatively took initiative and folded himself into his brother's arms in an apology of sorts. Their lips met and melded, Hikaru wanting to convey his sincerity and Kaoru's mouth wet and hot from crying and pleading. A minute later and Hikaru was stumbling toward the privacy of their bedroom, both arms struggling to support Kaoru's weight. The bathroom, soiled and stinking of their aunts' rendezvous, was not where Hikaru wanted to begin making memories.
By this time Kaoru was like putty in his brother's arms, too far gone in desire and too exhausted to argue with Hikaru's iron will. His eyes fluttered soundly shut as Hikaru lowered him on the bed and quickly began shimmying out of his jeans, a stiffened cock waiting to satiate the quivering body before him. Kaoru opened one eyes and with his foot vaguely pointed in the direction of the door.
"Don't forget to lock it, Nii-san."
