He doesn't but...

"Oh fuck, oh fuck, I can't hold it" Ben cried out as he built to a final release. With a scream, he explodes inside her with a blast of cum. For a split second the slick wet cunt around his cock seems to dissapear, then reappeared right back where it started.

"Don't worry about it, sweatheart." said Kitty. "I was able to phase out at the last minute, and it all kinda went straight through me." At Ben's questioning look, she giggled. "It's my power. I can turn intangible at will."

"Sweet." Ben said through a grin. "I'll have to remember that."

"No kidding! You're pretty damn addictive. I don't know if I should take you back to the school or keep you for myself." A wicked smile spread accross Kitty's face as she seductively licked her lips. She gyrated her hips slowly, and Ben, still inside of her, let out another groan. "How about round two?"

Obviously restraining himself, Ben gently withdrew his still hard cock from the girl. "As much as I'd like to, who knows what would happen if we kept going. I mean, I what would happen if I came inside you?" Though he was honestly worried about what could happen, he was also curious about who he could test it out on at this new school.

Kitty frowned "Good questions, but don't be surprised if you find me naked in your bed tonight, waiting for you."

And with that they got dressed. Blushing, and ignoring the looks they got from their fellow mutants on the plane, they sat down. The jet took off, heading back towards the Xavier Institute.
