When you heard Shamu's request, you realized that you're pretty exhausted after two consecutive days of body exploration and think that it's a good time to relax for a while, since you're technically on a vacation with whales.
"I would like a body massage, please Shamu," you said.
"It'll be my pleasure to provide you with some relaxation", said the bulky human Shamu, "Let's lie down and get ready, shall we?"

As you lie down on a fleshy bed, you begin to feel Shamu's powerful hands begin to run with extreme precision over your back. You felt her strong hands rubbing against sensitive parts of your back making you flinch reflexively with each pressing. Although she has assumed her human form, you feel that her hands are slippery and slick like the skin of a dolphin. Every rhythmic push and pull gives you an unexplainable tingle down your spine; a mixture of pain and comfort.

"Oh.....That feels so...good....", you exclaimed, "I never thought you're such a good massager."
"Hee..Hee.., thanks for the compliment, if you like this, I hope you would like some even harder."

Just then, Shamu starts to press down on you with her belly which caught you completely by surprise. Shamu's belly felt incredibly soft and it molds completely around your body. You felt her flesh moving over you, pressing down upon you. The feeling gives you creep since you never encountered any massage parlor that do such services.

"Oh...Shamu..this is outstanding....," you said.

Unbeknownst to you, Shamu reveals a wide grin at your comment.

At the end of the massage session half an hour later, you're feeling all relaxed and warm.
"Gee, thanks for the massage, Shamu", you said.
"It's always a pleasure to help you, my human," said Shamu.

You sit up and look at the bulky human Shamu for a moment... then you decided to ask her a question.

"But, I don't know if this is too much to ask about, since you told me that you are much older than Nakii is, does that mean you are also capable of doing far more than she can? I mean like can you assume several different forms like, you know, Mystique from the X-Men series?"

"Actually..I can", said Shamu boastfully, "The trainers I had eaten before have also made similar requests and I transformed into what I get from their minds. The reason I can do this is because I have no fixed (permanent) human form. In the current case, I could also change my human appearance to suit your taste. It can be anything out of the ordinary; I can assume shapes and things out of the realm of reality."

"That's great", you thought to yourself, "I'm not really a fan of huge, bulky women; you remembered an incident at the zoo when a woman even more bulky than Shamu tried to enter the turnstile at the entrance of the Africa exhibit and tripped herself. You happened to be on crowd control duty that day and that woman fell right down on you, nearly crushing you alive. You decided to not to think more about this out of fear you might hurt Shamu's feeling. Instead, you focus on thinking of the options that Shamu could transform herself into."

"I see", you said, "Hmm... what can I allow you to transform into?...", you said.

"Hold it. I think I kinda know what you want.", Shamu said gleefully.

Suddenly you saw the bulky Shamu before you start emitting a bright glow that encompassed her entire body. From her outline you can see the shape of her body becoming more and more slender and her hair becoming longer and more fluid. You stared in awe as Shamu transformed into who knows what.

After a minute, the bright glow started to dim and you take a good look at Shamu. What you see, made your jaws drop to the floor.

The woman before you has long flowing deep purple hairs, big and bright golden eyes, and an very slender shape you find quite attracting. The woman can't be real, you thought, She....she...looks more like something out of a Japanese anime.

"This is impossible, how the heck does she know I like animes and hot girls?", you thought to yourself.

She's wearing two oval hair clips on the two sides of her head and a black sleeveless summer dress with the intricate white markings of an orca. She still has a light brown tan to her skin and a curvy breast. Judging from her breathing and sighing, you bet she probably has a cute voice. All in all, she has turned into what you thought a human Shamu would be like.

Suddenly, the newly "reformed" Shamu dashed toward you and hug you tightly.

"Hi, human...",Shamu said in a slightly high squeal, "Do you like my new appearance, eh?"

"I....I...I... surely do.", you said, blushing.

"You seem..surprised about how I know about your secret hobbies, don't you?", asked Shamu. Then she lowered her voice: "It's Nakii who told me about it last night."

"Well that answers a lot of questions about you knowing more about me", you said.

"Alright. Let's keep the talks short. Say, are you feeling hungry at the moment?", asked Shamu, " If you are, wanna go to my Stomach bar for some nice meal I prepared for you?"

"Yea. I surely want to help myself to some food; I haven't eaten the whole day.", you replied, "But what's up with the 'invitation' ?"

"You've never "dated" an orca, have you?", said Shamu seductively, "Well, this is your chance! There, we have a lot to talk and share about."

Your heart is thumping rapidly from Shamu's suggestion. You've done something similar with Nakii, but she's a virtual human avatar and now, Shamu presented herself as a real girl, something entirely different.

"Alright, I'll go with you", you said.

"GREAT!!", squealed Shamu, "Then let's get going."

She dragged you by one hand through the maze of fleshy holes in her (orca) body toward the 'Stomach Bar'.
