Her feet left dusty footsteps on the surface of the moon as she paced towards the new arrival. Power Girl stopped just in front of him and cocked her head to the side. "I don't believe we've met..." she spoke. He extended his hand and she shook it. "I'm Superman," he told her.
Supergirl liked to fly low over the deep blue ocean, and just take in nature's beauty. She had to let out a shriek though when the ripples in the water turned to a massive splash up at her and a black projectile launched up towards her. "Don't be such a little girl," The other Supergirl laughed, dressed in a black copy of this world's Supergirl costume.
Superman had never seen boobs as big as Power Girl's before. Her blue and white armour were alluring and his eyes couldn't leave the open circle in the chest of her costume, although he did sneak a peek at her thighs, visible above her blue boots. He didn't want to waste time with foreplay, and he knew that she was checking him out as well, so he simply wrapped his arm around her waist, gave her butt a quick squeeze then pulled to him into a deep embrace.
The dark Supergirl had the blue one in a stranglehold with one hand and the other traced down her chest and under her skirt. Kara rubbed her good counterpart's vagina roughly as she struggled in her grip. "This is never going to work, we can't both be Supergirl" Kara taunted, "So how about I be Supergirl, and you can be Slut-Girl?" She took the moan escaping Slutgirl's mouth as a yes.
Powergirl didn't resist as Superman kissed her, his hands wandering over her body, loosening the straps of her costume. She had barely met him, yet she couldn't even try to resist him. She needed him. She felt her costume falling off her body and floating off into space as he stripped her. He held onto her belt and clipped it back around her waist after he'd got the rest of her costume off her as it was the only thing creating gravity to keep her on the moon. Superman stripped himself and her eyes landed on his huge penis.
Slut girl moaned out again and again as Kara fingered her pussy until she started to orgasm. There was a laugh behind her then she was plunged down into the ocean, Supergirl's arms still wrapped around her throat. Then, as fast as a speeding bullet they emerged from the water again, now dripping wet, and very naked.
Superman nailed Powergirl down onto the surface of the moon, his cock sliding in and out of her vagina at top speed. His muscular hands gripped her tits and pumped them up and down. He made no effort to hide that her breasts were the most spectacular thing about her in his mind. He pounded into her constantly but he never dropped her boobs. They were like basketballs in his grasp, being dribbled up and down her chest with the enthusiasm as of a youngster.
Kara had her bitch's head held down under the water with one hand and was eagerly spanking her ass again and again. She yanked slut girl's head out of the sea for air but slammed a finger into her tight ass, finger her butt forcefully. The other Kara couldn't register what was happening as she gasped for breath. One moment she had been doing her usual flyby, the next she was being screwed by a sex-crazed version of herself. "Well Slutgirl? Do you like this?" Kara demanded, releasing her ass and lifting her thighs up onto her shoulders so she could eat out her pussy. "YES!" Slutgirl cried out as Kara licked at her pussy. "Good... because you belong to me now, and I'm taking you back to my fortress to be one of my pets." There was a pause then Slutgirl answered: "Fantastic."
Superman drilled into Powergirl's ass now, but still clutched her boobs protectively. He could see Kara was tiring but he wasn't ready to finish yet. He lifted Kara up off the moon and for a moment they hovered over Earth, admiring the view. Then Superman plunged down with one almighty thrust and their two bodies zoomed down towards the surface of the Earth. They landed, with a splash, in the great blue ocean, right on top of a pair of Supergirls.
