Awwwww :-)
[His breath catches when her hand slides down inside his waistband - and then turns into a full-blown gasp when suddenly his pants go through him and land on the ground nearby. It's not a use for phasing that's ever occurred to him before (though it'll certainly inspire a few fantasies from here on in!) and so even though in their dream he's used to sex with Kitty, this is something new and thrilling.]
Wow. [He laughs breathlessly into her mouth, pressing close with his newly naked groin, gasping again as his erection presses against her hip. His coat's still around him, shielding them both, now that he's so close, from the mild chill of night and, actually, from the view of anyone who might pass by, though the park seems deserted.] You're a resourceful woman, Kitty Pryde. I've always wanted to find a way to remove my pants without having to remove my boots first!
