Yaoi, Onsen Lelouch x Suzaku

“I’m glad you like these hot springs, Euphy.”

Euphemia li Britannia, 3rd Princess of Britannia, had her eyes closed, the steam from the onsen water clinging to her flushed cheeks. She let out a soft, contented sigh. “Yes,” she murmured, the heat seeping deep into her muscles. “The water’s nice.”

She was sitting on the submerged stone ledge, a fluffy white towel pressed against her chest, held in place by her crossed arms. Her pink hair was piled in a loose, damp knot atop her head. In the steaming water, her bare feet flexed, enjoying the perfect, near-scalding temperature. To her immediate right, so close their shoulders brushed with every slight movement, was her brother Lelouch.

Lelouch was seated right next to her, enjoying the water too. On his lap was Suzaku sitting, with a small towel, covering Suzaku’s penis.

Suzaku enjoyed the warm water, too. His legs touched it. His ass slowly took in the rest of Lelouch's massive cock.

"I missed this," Suzaku said. "We should have visited an onsen sooner."

Lelouch chuckled softly. His hands rested casually on Suzaku’s hips, guiding the slow, steady roll of his sister's boyfriend’s body.

His cock sank another inch into Suzaku’s tight heat with a wet pop. The towel draped over Suzaku’s lap fluttered slightly with each thrust, but stayed in place—modest, even now. "You're right," Lelouch agreed, his voice perfectly normal. "The last one we went to was that tiny ryokan in the mountains. We stayed there for a weekend. Remember? The water wasn’t even this hot. This place is perfect.”

Euphemia opened her eyes just a bit, glancing sideways at the pair and smiling gently. "It really is," she said warmly, shifting so that her shoulder pressed more firmly against Lelouch's. The movement made the water slosh gently. She felt the subtle rhythm of her brother’s hips rocking upward and pushing deeper into Suzaku. "Suzaku's been so tense lately with all the knight duties. This is exactly what he needs. Right, Suzaku?”

Suzaku let out a soft, breathy hum as Euphemia laughed lightly and sweetly as she uncrossed her arms just enough to adjust her towel. The white fabric clung damply to her modest breasts. "You two are adorable when you get like this. I love watching you two relax together. It’s so natural.” She reached over and patted Suzaku’s thigh above the water, her fingers brushing the edge of the towel.

The contact caused Suzaku's inner walls to clench around Lelouch's cock instinctively, drawing a low, appreciative grunt from her brother.

Lelouch didn’t stop his slow, gentle thrusts. The water around them rippled minimally, hiding everything from casual view, but the three of them knew exactly what was happening.

Lelouch tilted his head toward Euphemia, his violet eyes half-lidded. "You should join us more often, Euphy. Don't just sit there. The heat does wonders for everyone.” He pushed up slightly harder, and Suzaku’s breath hitched for half a second before returning to normal.

"I know, I know," Euphemia replied with a playful roll of her eyes. "But someone has to keep an eye on the entrance. Last time, we got too distracted, and the attendant almost walked in.” Leaning her back against the stone ledge, she let the water lap at her neck and watched the way Suzaku’s shoulders flexed with each of Lelouch’s lazy thrusts.

The sight sent a warm, familiar thrill through her—her boyfriend, happily impaled on her brother’s cock, chatting as if they were having afternoon tea. It was their normal. She was fucked by Lelouch; she got fucked by Suzaku. But this way. She never tried it. She should buy a cute pink strap-on and fuck Suzaku's ass herself.

Her cheeks flushed, but her smile stayed. "Besides, I like seeing you two like this. Suzaku looks so content. Doesn’t he, Lelouch?”

agreement, his cheeks flushing further. His hands rested on Lelouch’s knees under the water to maintain his balance as he sank down another fraction of an inch, taking the last thick inch until Lelouch was fully inside him. The stretch burned in the best way—that familiar full pressure that made his cock twitch under the tiny towel. He could feel every pulse of Lelouch’s massive shaft buried in his ass; the head nudged right against his prostate with each tiny shift. "Mmm, yeah... exactly," he replied, his voice steady and casual as if he were commenting on the scenery. "The water makes it even better. We should book the private bath next time, too. There's less chance of anyone wandering by.”

Euphemia laughed lightly and sweetly as she uncrossed her arms just enough to adjust her towel. The white fabric clung damply to her modest breasts. "You two are adorable when you get like this. I love watching you two relax together. It’s so natural.” She reached over and patted Suzaku’s thigh above the water, her fingers brushing the edge of the towel.

Her cheeks flushed, but her smile stayed. "Besides, I like seeing you two like this. Suzaku looks so content. Doesn’t he, Lelouch?”

"Very," Lelouch said smoothly. He kept the rhythm: slow withdrawal, deep slide back in. He felt Suzaku's walls grip around him. The hot water made everything glide more smoothly. "He's gripping me perfectly today. Must be the minerals in the spring.” Lelouch said it so matter-of-factly that Suzaku actually laughed.

Suzaku shifted his weight, grinding in small circles that made Lelouch’s cockhead rub against his sensitive spot. A soft moan escaped, but he caught it and turned it into a casual sigh. "It feels amazing. You always hit the right angle, Lelouch. And the water makes everything warmer and wetter.” He turned his head to smile at Euphemia, his eyes bright with love. "You don't mind, do you? I know you wanted to visit the city.”

"Not at all," she assured him. "I'm glad you're enjoying yourself. You deserve it after all that training. Just make sure you don’t finish too quickly.” Lelouch has his chess tournament later, so let's enjoy the onsen first.”

Lelouch’s thrusts picked up the pace—not frantically, but deeper now. Each thrust pressed against Suzaku’s prostate, and the towel over his lap began to tent noticeably. His cock was leaking under the towel, but he kept chatting as if nothing were unusual. "I'll try, but you did remind me of the chess game."

Euphemia watched and felt her body respond with a slow, liquid heat between her legs. She didn’t touch herself; that wasn't the point. The point was seeing her boyfriend, happily stuffed full of her brother’s massive cock, smiling and talking as if it were the most ordinary thing in the world.

They spent the next twenty minutes like that—engaging in easy conversation while engaging in steady, submerged sex. Lelouch described a new strategy he’d been working on, Suzaku complained about the latest Knightmare simulator bugs, and Euphemia shared a funny story about her latest tea party with Cornelia. The whole time, Lelouch’s thick cock slid in and out of Suzaku’s ass.

Lelouch's grip on Suzaku's hips tightened slightly, and his thrusts deepened, prompting a quiet gasp from Suzaku. The towel over Suzaku’s lap twitched with each movement; his erection strained visibly against the fabric. "Close?" Lelouch murmured.

Suzaku nodded, his thighs trembling. "Yeah," he admitted breathlessly, grinning. His fingers curled against Lelouch’s knees underwater as he braced himself against Lelouch’s relentless pace.

Euphemia watched, smiling fondly, as Lelouch’s composure finally fractured. His hips stuttered and his breath caught as he buried himself to the hilt. His release pulsed hot and thick inside Suzaku. The groan that escaped him was low and private, almost instantly swallowed by the humid air. Suzaku shuddered, his own climax crashing over him a heartbeat later. The towel darkened with damp evidence and clung obscenely to his twitching cock.

For a long moment, the only sounds were their mingled breaths and the distant drip of water from the wooden eaves overhead. Then, Lelouch exhaled and loosened his grip on Suzaku’s hips. "We should move," he said pragmatically, though his voice was rougher than usual. "Before someone really walks in, we can do more in our room."

Suzaku slumped against Lelouch’s chest, his breathing ragged but slowing. Lelouch’s softening cock slipped free with an obscene, wet sound that made Suzaku’s toes curl. Euphemia giggled and reached out to tweak the edge of Suzaku’s towel where it clung to his cock. "You're a mess," she teased, her voice warm.

Lelouch exhaled through his nose, his fingers tracing idle patterns along Suzaku’s hipbone. "He's our mess," he corrected lightly, though his usual sharpness was dulled by satisfaction. Suzaku huffed a laugh and tipped his head back against Lelouch’s shoulder.
