"Feeling comfortable there, my little kitty?" Shen asked, a grin on his black beak as he stared at his tied prisoner.

The events at the Tower of Sacred Flame have been relatively... peaceful for Tigress and Raging River after Shen captured and added them to his little harem. They were left to sleep on comfortable pillows in his throne room and, while Tigress did not have to do anything except laying around and enduring the guards staring at her almost entirely naked body, Raging River found herself having to dance (sometimes alongside Viper) to entertain the peacock. Saying that both females were surprised that he did not do anything dishonorable to them after so many days would be an understanding. The only noticeable thing Shen made Tigress do was accompany him during the meetings.

However, today was different. After spending half of the day doing nothing but lying on her pillows and eating while Raging River danced, Tigress was brought by Wolf Boss into Shen's bedroom where she found herself getting tied to a wall with chains holding her arms above her head - the exact same way he tied her to his statue in the city before Raging River came to rescue her.

Until now, Shen made her wear all sorts of revealing, but still exotic and elegant, dresses. However, for some reason, he decided to make her wear her small ribbon top and loincloth for today. "Why did you bring me here, you maniac?" she asked.

Shen couldn't help but enjoy how his feline captive remained rebellious, even after being in his clutch for so long. "Oh, nothing special. It's just that since you have been so nice and obedient after becoming my little pet (Tigress growled at that), I thought it would only be fitting to give you a little... reward."

Tigress scoffed. "With your definition of "reward", I don't want it. I'm ready to bet you're gonna force me to dance for your own pleasure, just like you did with Master Raging River."

Shen chuckled a bit at this. "No offense, sweetheart, but I like my dancers to have a minimum of experience in that domain. You... You trained all your life in the ar of Kung Fu, right? I strongly doubt you took dancing lessons from your master." He then leaned his head close enough so that his beak stood right next to her ear. "No, your reward will be... different."

He snapped his feathers and the door of his bedroom opened. To Tigress' shock, her sister at arms slithered inside, closing the door behind her. "Viper!" The female snake's face still reflected no emotion as she went to bow before her master.

"Thank you for coming so quickly, my beautiful little Viper," Shen said with reaching his wing to stroke her chin.

"What have you done to her, you sick bastard?!" Tigress angrily said, struggling in vain against her bonds once more.

"I already told you, my little kitty," the white peacock mused. "I simply broke her will and made her submit to mine... Just like I shall do with yours sooner or later."

"You can forget that! Viper! It's me, Tigress! Why are you obeying this monster?!" Viper, however, did not respond and just stared blankly at the tied feline.

"Aww, there's nothing more adorable than seeing two sisters reunited again," the peacock said in a sarcastic tone. "Viper, it is time to give your sister her little surprise."

"Yes, Master..." Viper slithered all the way to Tigress' feet. To the feline's surprise, she opened her jaw and pulled the big toe of her right foot in her mouth to suck on it.

"W-What are you doing, Viper?" Tigress asked, shivering as she felt her toe getting sucked.

"You have sexual desires," Shen stated as he watched the scene before him, Tigress staring at him in both shock and horror.

"H-How do you know that?" she asked with a cracking voice while trying to get her foot away from the reptile who firmly held her ankle with her tail and kept sucking on her big toe while being careful not to cut herself on her toenail.

"Well," Shen said as he started walking back and forth, his red eyes never looking away from his prisoner, "I noticed that you excused yourself to go to the bathroom for pretty extended periods of times. And honestly, your scent pretty much says that you are horny - to anyone with a good smell at least." He then grinned. "From the stories I heard about you, you must never have done it with anyone before. Well, today is the day that you will lose your virginity. And who would be better to take it away other than...," his red eyes widened as he expressed his trademark sadistic smirk, "your own sister?"

And then, it happened. Tigress shivered as she felt Viper slithering along her back all the way up to her face so that she could press her red lips against the feline's black ones. The snake's lips were so soft and tasted like strawberries (probably because of her lipstick). This felt... weird and alien to Tigress. She shook her head and broke contact. She couldn't do this! Not to her sister!

"No! Stop, Viper!" the feline begged. "Please! We can't make out for the pleasure of this disgusting-" She got cut off by her sister who firmly brought her face back with her tail and kissed her again.

Shen smiled in delight as he went to sit down on his bed. This poor feline had been holding back her sexual desires for all of her life. But now, he would force her to accept and unleash them... by making her having sex with her own sister!

As much as Tigress tried to fight back, she could not deny that the strange feeling started feeling... good. Her resistance faded little by little with every second. Before long, her amber eyes closed and her furred tongue swirled around with Viper's forked one. The snake's tail slowly wrapped itself around the back of Tigress' neck - she wanted to take her sister's face with her paws, but the chains holding them up prevented her from doing so. Soon, the two girls broke apart due to the lack of oxygen, a trail of saliva connecting their lips.

Tigress breathed heavily, not knowing what to say. "Viper... I..." The snake silenced her by putting the tip of her tail on her black lips. The way her turquoise eyes were half-closed and emotionless somehow made them more seductive to Tigress. She brought her blood-red lips to her cheek where she started giving quick sweet kisses, slowly moving down to her neck.

For the first time in her life, Master Tigress did not know how to feel about this situation. The evil peacock forced her to make out with her sister in arms. It should feel wrong to her. But... it didn't. Even if they were of different species, Viper and her were not sisters by blood: it's a bond they formed through the love of their family... a family that no longer existed. So... what was it exactly that would prevent them from doing this?

As she rubbed her forked tongue against her sensitive ear for wet licks, Viper coiled herself around Tigress' neck, her tail resting against her toned abdomen. She plunged her turquoise eyes into the feline's burning amber ones while bringing her tail up to pull her ribbon top down, exposing her babyfeeders that bounced a bit from the action.

Shen looked at them with the most satisfied expression his feathered face could show. "Yes, yes. Go on, Viper. Satisfy your sister, make her scream..."

As soon as her master said this, Viper coiled her body around her sister's round, firm breasts before reaching her tail down her loincloth to enter into her. The feline gasped as the snake squeezed and entered her, the scaly texture of her body feeling so good against her fur... and insides. Not stopping there, Viper brought her head down to press her lips against Tigress' nipple in order to suck it the exact same way she did with her toes at the beginning.

Just as the very tip of Viper's tail hit the top of Tigress' girlhood, both the girls' privates touched each other, erecting jolts of pleasure out of them. Viper almost bit the feline's nipple as she felt her inner muscles squeezing and pulsing against her tail.

"Viper... this is... so... GOOD!" Tigress moaned, her face turning so red that Shen could see it behind her orange fur. With a swift, firm move, Viper pulled her tail out of Tigress' now wet girlhood. However, this was a trick as she shoved it right back inside immediately after, causing her to let out a noise somewhere between a moan and a scream.

"Very well, Viper," Shen said, a satisfied smile on his black beak. "Now give her your BEST!"

Not taking her tail out of her slit, Viper brought her head down to Tigress' groan and wrapped her forked tongue around her clitoris to hump it up and down. Whilst she did this, her coils kept squeezing her breasts to the point that if there was milk in them, it would have spilled out by now. Tigress was moaning with her mouth wide open as her orgasm was building up fast because of the tail thrust inside her girlhood mixed with the way her breasts were squeezed and her clitoris licked.

And then, it happened.

Tigress' moan resonated like a powerful roar that echoed throughout the whole tower, scaring everyone living in it. Her juice exploded all over Viper's tail and formed a small puddle on the floor. After what felt like an eternity, but was actually twenty seconds, Tigress' first powerful orgasm came to an end, leaving her body drenched in sweat... and fluids.

Before she could thank her beloved snake and kiss her, she just pulled herself out of her body and slithered back to her master's side, as if nothing happened. This left a trail of the feline's juices on the floor. Shen stood up, walking over to Tigress so that he could stroke her chin and make her amber eyes look into his red ones.

"Pleasant, was it?" As much as she hated to admit it, Tigress could not deny that she DID enjoy it. "Keep acting like a good girl, and you will receive rewards like this as much as you want." Shen then twisted his beak into a grin. "Maybe even every single day for the rest of your life..."

Author's note: Well, that happened. Shen forced Viper to make out with Tigress. That wouldn't count as incest since they are technically not sisters related by blood, but rather in a spiritual way.

Before you start rambling out, I wanna point something out: Tigress will NOT submit herself to Shen from now on. She still have some fighting spirit and hope to bring peace back to China. She will only be... different after this experience.

For the next chapters, we are going to move away from Shen's tower because I think I have shown pretty much everything interesting that could be done for the moment. It's time to go hunt for some... fresh meat ;) As always, constructive reviews are welcome and may the gods watch over you all.
