Logan could sense no hesitation in Jean, and that was all the permission he needed. He kissed her again, and if alloweed he'd grab her firmly by the buttocks and carry her to his bed, torn sheets and clawed mattress notwithstanding. He would lay her down as gently as he could and, careful to keep the full weight of his adamantium off her, would lie half on top of Jean, limiting himself to exploring, for now. He would kiss and nuzzle and nibble and rub his face gently all over her neck, like a beast instinctively marking his territory with his scent. When he realized what he was doing, he sincerely hoped he wouldn't feel the urge to pee around her room next. This feral thing was sometimes ridiculous to him, but he couldn't control instinct, he could only temper it with his humanity.
A cupped breast, and kisses on every bit of her exposed flesh that began turning moist as he mouthed his way around, and then he'd start gently pulling on clothes. If her thigh got close enough to his crotch, she would feel exactly how much he wanted her right now. Already connected on a deeper level, instinct to telepathy, he would see no need to stop the course of nature unless Jean expressly put a stop to it. His hands would grow bolder, seeking to feel her skin to skin.
