You'll stay as Dialga, and keep Palkia like she is now.

Chapter by Nenen

You think for a bit, then shake your head. “No thanks, I think I’ll stay put for a while.” You tell her. While sure, you could go for Arceus and you’re pretty sure you could get her, why hurry to do so? You think you’d rather enjoy each and every legendary first before going for the big one. Besides, Dialga’s body is pretty nice to have. “You don’t mind if I stay in your sister’s body, right Palkia?”

“Of course not Mistress! I hope you enjoy my sister’s body as long as you like.” She says with a smile, making you smile as well as you kiss her again, loving both the feeling of the act and the act itself.

You break the kiss and look at her for a bit. “Alright then, I’d say you should go and continue on with your life Palkia, ah, and only call me Mistress and act like this in private. For now I will get comfortable in this body.” You say, with Palkia nodding with a smile as she gets up and leaves the bathroom, leaving you alone in Dialga’s body. You get up slowly, stretching and feeling the muscles of her body respond to the stimulus. You once more run your hands across the curves of Dialga’s body, admiring her massive breasts and big, firm ass. A smile crosses your face as you feel her body responding already to your touch. “You know, if I didn’t know better I’d say you like this, eh Dialga?” You say to no one before chuckling lightly. You give her ass and breasts some good groping for a bit before letting go and deciding to clean up.

Letting the cold water of the shower hit you feels incredible in Dialga’s body, after all the things you did with her and Palkia. A smile crosses her lips under your control as you simply stay there under the water. Your hands begin to roam across her body, moving across her curves as the water refreshes you. Feeling giddy once more you give her massive breasts some good groping, moaning softly with her voice. Her nipples start to harden as you trace circles around them, a heat beginning to build once more between your legs. One hand remains teasing your massive tits while the other moves lower, feeling the firm curves of your ass and groping it. A finger starts to tease your rear hole as you move Dialga’s tail out of the way. You circle her puckered hole for a bit before slowly inserting a long slender finger, moaning as her muscles instinctively clamp around it. You begin to move the finger in and out, teasing a specific spot inside as your other hand tugs at your stiff nipples, eliciting more moans.

Soon, you have gotten a constant rhythm as you play with Dialga’s body, moaning louder with each second as you grope harder and use more fingers on her rear hole. The feeling of her breasts molding to your hand, spilling from between your fingers due their sheer size. The feeling of her inner walls clenching against your fingers, the heat you feel through it, it all is too good. You’re starting to feel weak on the knees as the pleasure begins to increase, but you don’t stop. Rather, you redouble your efforts, groping with more force and pushing your fingers faster. Before long, the feelings become too much to bear, and with a final loud moan you come undone.

A minute or so later you are smiling once again, having had some solo fun as Dialga. Feeling you’ve been in this bathroom too long you decide to actually clean yourself up properly. The water feels great after the most recent orgasm, and you sigh contentedly as you ponder what you will do next, be it with this body or any other.

Suggestions:

•Mess around with Dialga's powers a little

•Mess around with Palkia again, some sisterly 'fun' sounds good

•Something else
