Feeling very exposed at your confession, I pull you close to me, and give you a soft kiss.  "Liliana, you do not need to shut up, I am just a much older man and am not comfortable in this situation. If you truly someday feel strongly about me, then maybe we can discuss it further.  But right now, I do not want to feel like a kidnapper."  I give you a smile and stroke your hair, letting my hand fall to your shoulder and pullng you close.
