Goku, what you are describing is SO VERY NORMAL. Most guys do get that excited and do ejaculate in their pants when making out with their girls. Frankly, I think it is less embarrassing to admit that she made you come, than to tell her you wet your pants. Next time it happens, tell you she makes you so hot that you can't control yourself and it happens to all guys who have hot girlfriends. After the shock of it, she will be flattered that you find her so attractive. You can't keep telling her that you peed your pants or else she will think something is wrong with you. Man up!
