“Kyaaaaaa!” A girlish scream echoed around the onsen for a brief moment, along with some splashing sounds...

“P-p-p-penisuu?!!”

The one making such a scene was none other than Leafa, the only blonde among them who also happened to be the loved ‘sister’ of one Kirito.

As the blonde sylph struggled desperately in panic because of seeing something that she definitely thought that she shouldn’t, causing Asuna to be momentarily distracted, loosening her grip only for a moment which was all it took for the blonde sylph to break free from her hold, and in her panic, she unintentionally summoned her green faery wings only to lose control of them, crashing on what’s nearest in front of her; her brother, who thankfully had managed to stay his ground and stop her thanks to his considerably higher then average strength stat.

It didn’t take even ten seconds for everything to settle down when she noticed something strange about herself...

Her clothes were wet, but that was only to be expected considering the situation.

What felt foreign to her was... Not only was her hands grabbing something really soft and smooth to the touch, but she also felt that there was something hot and hard stuck in between her breasts. And there was that funny smell too, which was beginning to making her more excited by the ‘minute’.

The moment that she opened her eyes, curious to find out the cause, she was left stupified with what she was faced with...

Apparently what she had been feeling with her hands were the result of her grabbing her onii-chan’s buttocks due to her ‘hugging’ him... Not only that, but the warm tickling sensation she had been feeling on between her breasts was none other then her onii-chan’s erect penis!

“Heh? H-how?”

It was not evident for Leafa at the time, but she wasn’t wearing her usual belt, so during her fall, ‘it’ must have somehow found a way in from the crack of her green outfit right under her chest...

As she looked up in disbelief, she could see that her brother who now for some reason looked much younger than he should have was silently looking at her with his mouth agape with incredulity...

“O-onii-chan?” She managed to blurt out, turning her gaze back to his hot throbbing member sandwiched between her breasts, then back to him...

This went on for a few more seconds as she repeatedly looked back and forth, then, after comprehending the situation, she cried out, hyperventilating...

“Penisu! Onii-chan’s... Peniphueaaa...”

It was only natural for a young woman her age to be freaked out by suddenly seeing the opposite sex exposed, especially when said opposite sex was none other then her beloved onii-chan.

Also as an inexperienced woman with an isolated background, she was too overwhelmed by her condition to stay conscious as she eventually fainted on the spot, which made her unable to keep her hold on her brother, with her body slowly sliding down against him only to eventually ‘coming to a stop’...

As it so happens, the only thing keeping her head from sinking into the water was none other than her brother’s hard ‘stick’ which was still stuck between her breasts, this time to the point of even entering her open mouth...

“Haghh!” Kirito couldn’t take the sudden stimulation that his ‘sister’ ignited within him as he began shamelessly cumming inside his sister’s mouth, right in front of his wife...

Even though it was not physically that hard to free his cock from the ‘clutches’ of his sister, his lust was just too strong for him to resist it as he grabbed hold of his sister’s breasts, compressing them to his member tightly, and frantically started thrusting his hips in accordance with his spurts...

Even though only his glans could reach inside of his sister’s accommodating mouth, it still felt really good for the male high-sylph combined with the soft sensation that her breasts provided... He was really in heaven...

Asuna just stood there in her naked glory, watching the scene in depraved curiosity of her husband cumming inside of his sister’s mouth as she unconsciously started fingering herself. She was really aroused watching her Kirito-kun so crazed for sex, even though she should be feeling angry...

When Asuna has sex with her beloved, she mostly focuses on the feeling of love and trust that she feels towards her partner, but now watching him being intimate with another woman ignited something deep within the high-sylph. It was fascinating... She was really fascinated by her newfound primitive feelings of jealousy and lust... She simply desired for more...

Just the sheer sight of her Kirito-kun’s ‘silver potion’ — which should have belonged only to her and her alone — shamelessly spilling out of the blonde female sylph’s mouth as a result of her brother’s endless spurts continuously filling inside her mouth which she obviously couldn’t take and spilled all over her milky breasts as a result, was simply beautiful...

Thankfully the girl’s gag reflexes worked just fine even in her unconscious state, otherwise she could have been definitely drowned in her brother’s abundant seed...

Half a minute later found a satisfied but equally guilty Kirito who had just finished placing his sister’s unconscious body gently on the dry ground beside the onsen after he had his way with her, avoiding looking at the direction of his wife who obviously was out of breath, staring at him with a complicated expression.

“K-k-kirito-kun...” She weakly blurted out, making Kirito wince...

Even though he was quite sure that she was hurt, not to mention angry at his ‘betrayal’ right in front of her, her next words proved that he couldn’t be any more wrong.

“Fuck me...” she wantonly stated, her hazel eyes shimmering in the ‘moonlight’.

“Haii!?” Even though he couldn’t fully believe what he was hearing from his Asuna, his softened member nevertheless responded to her perverted words instantly by pointing towards it’s ultimate goal, harder then ever...

Seeing his penis getting hard and ready for another ‘round’, Asuna then turned around, finding a suitable rock to lean on, she presented her perky white ass to the ‘serving’ of her male whose gaze was absolutely fixed on her special ‘spot’ that he was denied access to till now as she then gave out the finishing blow,

“Saa, come. I‘m going to drain your balls tonight so much that your cock will never, ever think of cumming inside other girls ever again...” she said, with only her head facing her lover as she cracked open her butt-cheeks invitingly...

After his ears heard of such a taunt coming from his wife, it was only ‘natural’ that he lost it as it didn’t even take him a second to activate his ethereal black alf wings and reach for his lover, embracing her tightly from behind, to the surprise of the erotic high-sylph.

“Eeh?! Ki-” Without wasting any more time, he swiftly inserted his hard manhood inside of her already wet ass, making her scream his name,

“RITO!”

While all this was happening, a certain Faery Lord of the Sylphs was ‘busy’ with ‘trying out’ the spells in her repertoire, especially the ‘Peeping’ spell which she had casted on her second-in-command; Leafa, was paramount in her ‘research’...
