The three go someplace a little more private

Charlie shivered as they flew at high speed above icy wastes but his mind was anywhere but on the cold. Just minutes ago, he was a normal guy living a normal life. Now, Power Girl - the real Power Girl - held him close as they flew, letting him eagerly explore her famous chest with his mouth and hands. She actually moaned softly at his fumbling, inexpert second base groping at first, then eventually just tearing her blouse off and yanking her bra down, groaning in delight as they flew somewhere "more private" per the request he'd made the moment they'd all made their way out of the French restaurant.

"Be careful not to drop him!" he heard Kara say.

"Are you crazy? I'm never letting this stud go." Karen replied, her voice husky with desire as one hand grasped his hair and another wrapped around his waist.

He stopped suckling her nipple with an audible pop as the clouds cleared. Charlie's jaw dropped as he saw a beautiful, strange crystalline structure below. Karen made a disappointed noise as he did so.

"What- what is this place?" Charlie asked in awe.

"The most private place we know, Charlie - our cousin's Fortress of Solitude." Kara said with a smile as they flew in front of a massive door. She landed in the snow but Karen kept them hovering a few feet above and kissed him passionately now that his mouth wasn't occupied.

Placing down the bottle of wine they took from the restaurant in the snow, Kara walked over to a large boulder and moved it effortlessly. She then lifted an enormous golden key and inserted it into the door, opening the entrance and then replacing both key and boulder where she'd found them.

Charlie didn't have time to register the sights and sounds as he was flown down past the entranceway and through gleaming corridors. One moment he was outside the strange structure in some sort of arctic wasteland and the next he was being tossed onto a huge, lavish bed due to Power Girl's superspeed flight.

"God, the things I am going to do to you!" purred Karen huskily as she began sliding out of her clothes, getting down to just her panties as Kara flew in after them.

"Hey, no fair! He said he wanted to see both of us being 'friendly', remember? Wait for me!"

Kara slid out of her civilian outfit at superspeed, suddenly beaming and naked next to her cousin.

"Kal's bedroom? Why not one of the guest rooms?" she added, pausing suddenly.

"Biggest bed. Most room. Shut up and kiss me." Karen snapped in response as she tore off her soaked panties and bent over to kiss her more petite cousin full on the lips.

Charlie's cold quickly vanished as his blood ran hot at the sight in front of him. Kara responded to her cousin's aggressive kiss by sliding her petite hands up to her tits and squeezing them firmly. Karen ran her hands down Kara's back to squeeze her pert ass roughly in response. Both women let out muffled moans of delight as they did so.

Charlie still had a million questions but he wasn't going to be dumb enough to ruin this once in a lifetime opportunity by asking them.

He practically tore off his work shirt in his haste, tossing all his clothes off haphazardly in an urge to join the two blondes in their nakedness as quickly as possible. In no time at all, he was naked and rock hard, crawling to the edge of the huge bed with red sheets.

Just as he was about to join the two women, a floating droid attempted to enter the bedroom, sputtering "Karen Starr, Kara Zor-El, you have brought an unauthorized visitor to the Fortress without the presence of Master Kal-El. Shall I-"

"Turn off security protocols and leave us alone!" growled Kara as she broke the embrace and slammed the door to the bedroom in the droid's face.

Charlie didn't care about any of that. He stood up with a huge grin, drinking them in.

"Enough making out with each other. I want the both of you to come over here and fuck me." he said, incredible lust making him more confident than usual.

The blonde beauties didn't need to be told twice. In a whoosh of air, each of them was grinding against one side of him, Kara to his left and Karen to his right.

"Fuck me, Charlie, please, I need it so bad!"

"No, fuck me first! I've never had that perfect cock of yours and I need it inside me now!"

Charlie smiled as he tried to decide how this threesome - his first - was going to play out. Nothing could ruin this day!

Ursa blinked in shock as she saw three figures, two of whom could only be Supergirl and Power Girl, fly to the Fortress of Solitude, open up the door and fly in, leaving the door wide open after doing so.

Could this somehow be part of Zod's plan? He had planned to allow himself to be captured and then trick the Earth-loving Kryptonian fools into going into space on a fool's errand, faking his command over a fictional alien armada, leaving Ursa and Non to find their way into Kal-El's famous Fortress to use and then sabotage the Phantom Zone projector. The final step of the plan was to overrun this planet with Krypton's worst criminals and use the chaos to take it over but step one had proved impossible. Their attempts to even enter the facility had been futile for weeks, as the pair fruitlessly searched for egress . . . until now.

The door was wide open. Was this some sort of trap? Ursa used her heightened senses, scanning for any sort of tricks. Nothing caught her attention, save for a strange, pleasant scent in the air.

"What is that?" she murmured to herself, breathing in deeply and tasting the delightful smell.

She was going to ask more questions when she heard a metallic voice say "Security Protocols Disengaged." and a faint hum stop. The door closed slowly but remained open just a small crack.

She turned to her huge brutish companion with a smile on her full lips.

"I think luck has finally smiled upon us, my friend."
