Though he managed not to let his grin drop as the twins began, the doubt in his eyes was fairly obvious.  It vanished once they kissed his cheeks, and he does a good job of catching Amy when she leaps.<br/><br/>"S-"<br/><br/>Whatever he tried to say was squelched by the kiss (it couldn't have been very important anyway, right?) and he quickly returned it, eagerly and with quite a bit of tongue.  Lily's touching made his arousal rather apparent, but for now he had his hands full - literally - with Amy.
