Merge their minds

"Are you sure this is a good idea master?" the younger of the two doppelgangers said.

"Yes I think it's a great idea." you say "After all what's better than one cosmically powered goddess than two cosmically powered goddesses."

"Okay" Marvel Girl says with just a slight hint of fear in her voice.

"Phoenix are you ready to start?"

"Of course, Master but this may take awhile" with that Phoenix eyes start to glow as the initiates a mental link with Marvel Girls mind. The younger Jeans eyes shoot open and start to glow matching her older self's. After waiting a couple moments you decide to have some fun. Tearing a hole in the prone redhead bodysuit you reveal her perfectly shaved slit. Lowering your head to her crotch and giving her a cursory lick you both Jeans seem to react in unison with a moan. It seems in their linked psyches they can feel each others pleasure. With this fact revealed you decide to exploit it while eating out Marvel Girl you reach over to Phoenix and begin fondling her clit through her spandex suit.

The moans in stereo makes your cock spring to life, which in turn causes you to lose interest in eating out Marvel Girls box. Raising yourself up you quickly plunge into the younger Jeans cunt. Quickly bringing yourself up to speed you continue to manipulate the Phoenix's clit. Soon both are screaming in orgasm with your manipulations. You spray your seed onto Marvel Girls stomach and collapse onto the bed contented for the moment.

Not long after you finish both women speak in unison "Thank you for opening our eyes to your glory master."

"You came in unison and now your speaking in unison, why's that?" you ask.

"When I shared a portion of the Phoenix **** with her-" the older Jean speaks.

"We merged into one now we're one mind in two bodies both the Phoenix"
