A hole new different crush.

So here's a hole new diferent crush.
At first it seems like the office cliche, but then i realized it's nothing like that.
I'm sort of his supperior, but he's 26 years older than me. He's not beautiful, not the smartest person i know, we have absolutely nothing in common.. but still, he shows up at my office and i just want to take off his pants with my mouth.
I have no idea if he even thought about me that way. He made jokes about it, but then, like a gilr in her period, he becomes all cyclotimic and acts like he didn't see me.

A week ago, i actually had to go near his place, so i ask him for a ride. We get in his car and all the porn with stories i ever saw went trhough my mind in ten seconds, but we both been polite and growups. We talk about his kid (who is sixteen, what te fuck am i doing??), about my smoking and how i don't wanna quit even i know i would die of cancer, about work, about music in the radio and how we love the 80's, about how we both drink light coke, stupid things to not talk about the giant pink sex elephant.
When he left me, he asked for coffee 'cause i have to wait some time, but i declined it (again, why? seriously). And it was it.

I know i can't fuck anyone from work, and maybe that's the only reason i want him so bad.
I know we can both get fired, i know i wont ever love him, it's just a crush, I hate those kind of crushes, make me feel a fifteen-year-old. It's the kind of crush that wont stop until it happens.
