The world tilted.
Her words were a key turning in a lock he didn't know existed. "I've waited long enough." The phrase echoed in the steam-filled room, shattering the flimsy barrier of denial he'd tried to build.
In truth, Alex didn't really care that she was his 'sister' since he didn't have any memories of the previous Alex, and since he was a soul from another world where he didn't have any siblings, the taboo was there, but it didn't have the same weight as a lifetime of shared memories and familial bonds. But he still resisted.
"I..." he started, the protest dying on his lips as Sera leaned in again, her intentions clear.
This kiss wasn't the soft, tentative press from moments before. It was a hungry, claiming thing. Her tongue swept past his lips, tangling with his in a dance that was both familiar and utterly foreign. She tasted of mint and a sweetness that was all her own.
[Go on, Alex,] Lily's mental voice was a dark, encouraging whisper in the back of his mind. [Take what you need. Her desire is practically a feast.]
Alex's hands, which had been resting uselessly at his sides, found their way to her waist. He could feel the soft skin, the curve of her hip, the dip of her spine. He pulled her closer, the water sloshing around them, their bodies sliding together, skin on skin. It felt electric. Forbidden. Irresistible.
"Ahhh~..." Sera moaned into his mouth, a soft, desperate sound that sent a jolt of pure arousal straight to his groin. Her hand, which had been holding him beneath the water, began to move again, a slow, deliberate pumping that made his toes curl.
"You're so big," she whispered against his lips, her eyes wide with a mixture of awe and lust. "Bigger than I imagined."
She broke the kiss and began to trail her lips down his neck, her tongue leaving a wet, warm path. She nibbled at his collarbone, her teeth scraping gently against the skin. He was hers to explore, and she was savoring every moment.
[That's it. Let her take the lead,] Lily urged. She was with them in the bath, but no one could see her, already starting to pleasure herself with her other hand under the water, 'enjoying the show,' as she called it. [I want to see how far she'll go for you.]
Alex's mind was a haze of conflicting signals—denial, need, the phantom ache of his drained body suddenly drowned out by something much more primal.
Sera pulled back just long enough to look at him, sapphire eyes half-lidded and dark. Her lips were swollen, parted, a faint sheen of moisture catching the soft light.
"Still going to tell me we can't?" she whispered, voice husky, her right hand gave one big, long stroke from base to tip, her thumb rubbing the sensitive spot under the head.
Alex's jaw clenched, a low, helpless groan breaking past his lips.
"Sera... this is..."
"Perfect," she finished for him, her voice a sultry purr.
Before he could offer another half-hearted protest, Sera released him only long enough to rise slightly, water cascading down the soft curves of her breasts and the flat plane of her stomach, but lower was still wrapped with the towel.
She pushed him gently until Alex's back rested against the tiled edge of the bath. Then she leaned in again, kissing him once more—deeper this time—before trailing her mouth lower.
Her lips brushed the edge of his jaw, the hollow of his throat, the collarbone she had already marked with her teeth. She nuzzled lower still, her dark blue hair floating around her shoulders in the steaming water like ink spilled in silk. One hand stayed wrapped loosely around his cock, stroking in lazy, maddeningly slow pulls while her free hand braced against his chest.
"I've wanted this for so long," she murmured against his skin. "Wanted you like this. Just for me."
Her tongue traced the outline of a muscle on his chest, swirling around a nipple. Alex arched against her, a choked breath escaping him.
"You taste like heaven."
When her lips reached the line of the water, she paused. Alex watched, heart hammering, as she guided the flushed head of his cock above the surface. A single droplet of clear fluid beaded at the tip. Sera's eyes flicked up to meet his—sapphire dark with hunger—before she leaned in and dragged the flat of her tongue slowly across it.
"Ohh…" Alex shuddered, a tremor running through him. He could feel the heat coiling in his belly, tight and fierce; his only thought was to ram it back down her throat.
[Oh, she's good,] Lily breathed, her own invisible form shifting somewhere nearby in the steam. He could feel the faint pulse of her arousal bleeding through their bond as she touched herself, watching. [Look at the way she savors you. Don't you dare stop her or I'll take over and do it myself.]
Sera took that first taste as permission. She parted her lips and sank down, warm, wet heat enveloping the head of his cock. Her tongue swirled, slow and thorough, mapping every ridge and vein while her hand worked the shaft. She took more, inch by inch, her throat relaxing to accept him deeper.
"!!!" Alex gasped, hips jerking involuntarily, shoving himself deeper into her welcoming throat.
Sera hummed in approval; that showed that her twin brother was enjoying her service and wanted her as much as she wanted him.
'I really do like the new him... he's way more fun and much cuter than the old cold one,' Sera thought.
Water lapped at her cheeks as she bobbed, slow at first, then with growing confidence. One hand cupped his balls beneath the surface, rolling them gently; the other braced on his thigh, fingers digging in whenever she forced herself a little farther down. Every so often she'd pause, pulling back until her lips grazed the tip, then plunge again, taking him to the hilt until her nose brushed against the dark hair at his base. Enjoying the story?

Spit and bathwater mixed, slick and glistening, dribbling from the corners of her lips to merge with the pool's surface. It made the whole act more... erotic.
Alex's head fell back against the tiled rim. His hands found their way into her hair almost of their own accord, not forcing, just holding, feeling the wet strands slide between his fingers as she worked him with single-minded devotion.
"Sera..." His voice was rough. "If you keep—"
She answered by sucking harder, cheeks hollowing, her tongue pressing insistently against the underside of his shaft. Her fingers tightened around his base, pumping in counterpoint to the rhythm of her lips. Every time she bottomed out, nose brushing the dark hair at his base, she'd swallow, then make it her goal to 'kiss' the root.
"Sera.... I'm going..."
Alex's fingers tightened in her hair. His hips rolled up, a desperate, instinctive motion to get deeper. He was close—too close—and the way she looked up at him through dark lashes, sapphire eyes half-lidded with pure hunger, only pushed him closer to the edge.
[She's going to take it all,] Lily murmured, her mental voice thick with shared arousal. [Don't hold back. Let her have it.]
Sera seemed to sense it too. She doubled her efforts, her movements becoming faster, more urgent. She was like a starving woman, and he was the only banquet she desired.
"AHHHH~"
Finally, with a harsh cry, Alex's hips jerked once, twice—
Then he came with a low, broken groan, spilling heavily into her mouth. Sera didn't pull away. She stayed locked around him, swallowing greedily, her throat working in steady pulses as she drank every drop he gave her. Only when the last spurt faded did she slowly ease back, lips sliding off him with a soft, wet pop.
A thin string of saliva and spunk connected her lower lip to the head of his cock for a heartbeat before it broke. She licked her lips slowly, eyes still locked on his, then she opened her mouth to show him the small amount of cum still there, before swallowing it again.
A wicked, triumphant smile lit up her face.
"You taste even better than I imagined, brother," she whispered, voice husky. "Damn, if I knew that you were this fun, I would have done that sooner!"
[Magnificent.] Lily's voice drifted through Alex's mind like smoke, rich with satisfaction. [I think I'm in love.]
Before he could even process—before the shame or the pleasure could fully settle—she shifted in the water. She pulled herself up and rested her forearms on his chest. She looked up at him with those half-lidded sapphire eyes, flushed from heat and exertion.
She leaned in and gave him another deep kiss, letting him taste himself in her mouth.
"I'm glad you enjoyed your little 'treatment', but we aren't done yet," she whispered. "You need to return the favor."
"Eh?"
Sera didn't wait for a response. She simply sat on the submerged bench and reached for the towel still wrapped around her waist. She unwound it slowly, holding his gaze the entire time, letting it float to the surface of the water between them.
"???"
The confusion hit him first. Then the visual caught up with the confusion.
Below the soft taper of her waist, beneath the gentle flare of hips, rising thick and already half-hard from the attention she had just given him, was a cock.
It was elegant in the same way the rest of her was elegant—smooth, perfectly proportioned, the head flushed a deep rose and already beading with clear fluid. Not as long as his, but beautifully formed, nestled against the soft curve of her lower stomach above a neat thatch of the same dark-blue hair that framed her face. It twitched once under his stunned stare, as if aware of the attention.
Alex's mind went completely blank for three full heartbeats.
"You're staring."
Surprisingly, Sera looked away for a second, a flicker of something almost like shyness crossing her features.
"It's... not a problem, is it?" Enjoying the story? Read on at g.com.
A problem? It was a cosmic-level rewrite of everything he thought he was dealing with. A twist in a narrative that had already taken several hard turns into the abyss. His brain, already struggling to process incest, now had to add this to the list.
"Wha... you..." he finally managed, the words coming out as a choked stammer. "You have a..."
"A dick, yes," Sera said, her usual playful confidence returning.
"How?"
"I guess you didn't just lose your memories but your 'education' as well." She sighed dramatically. "Mom will be disappointed."
She looked at him again, her head tilted, studying his reaction.
"Well... more than 70% of women in the world have a 'sword' in their 'sheath'," she said simply. "We're called 'Futanari'. It's common."
'Futanari... Lily, did you know about this?' Alex thought in full panic.
[Of course, did you forget that Dr. Linda has a cock?] Lily's mental voice was filled with delighted, cackling laughter. [Oh, this world just keeps on giving! A built-in smorgasbord! This is the best news I've heard in a thousand years!]
'Don't sound so happy about it!' Alex shot back, his internal world spiraling.
[Why not? This solves so many of our problems! You get the feminine beauty you're drawn to, with the equipment you're already becoming... proficient... at handling. It's perfect!]
'You're insane.'
[And you're hard again,] Lily pointed out cheerfully. [Look down.]
Alex did.
She was right. His cock, which should have been spent, was already thickening once more beneath the water, responding to the sight of Sera's own arousal and the sheer absurdity of the situation.
Sera noticed too. Her eyes dropped, then lifted again with a small, knowing smile.
"Oh, so it's not a problem," she purred. "I guess brother still loves me after all."
Her confidence was back in full force, eclipsing the brief moment of vulnerability. She leaned closer, her breasts pressing against his chest, the hard length of her cock rubbing against his.
"You're my twin, Alex," she whispered, her lips brushing against his. "We're the same. Two halves of a whole. Doesn't this... make sense?"
Sense was a long-lost relative in this steamy room. All that was left was... a fucking hot girl with a dick.
"So… will you return the favor? Or do I need to beg a little more?" she asked, her voice a sultry challenge, her hips rolling slightly, rubbing her erection against his thigh. "Or maybe I should just take what I want?"
Alex's mouth opened, closed, then opened again. The last of the pure shock was starting to settle into something hotter, heavier. The taboo had already been shredded; this new layer simply finished the job.
"…You're serious," he said, voice still rough.
"Completely." Sera reached out, took his hand, and guided it down through the warm water. She didn't force him, but she didn't let him pull away either. "I've waited years for this, Alex. For you. I'm not letting you go now."
Her voice dropped to a near-whisper.
"Please, brother."
[Do it,] Lily urged, practically vibrating with excitement. [She's offering. You're both already soaked and hard. Stop overthinking and start tasting.]
