I work for a signage company full-time and part-time at night for a dry cleaner. I usually work with a 18 year old girl who commutes to school. We've been working together for 8 months. She's this tiny blond. Cute, big boobs. Big butt but still sexy. She has a boyfriend who I've met a few times. They have been together for a long time.

For some reason, she likes to fuck me. One night, after working together for about a month, out of the blue she asked me if I wanted to have sex. Of course I did. She's 18 I'm in my forties.

I said I did and she started stripping. We made out, gave each other oral and we fucked in the back room. Been doing it ever since a couple of times a week most of the time. She never gets emotional about it. Never really talks about it. Were not even really that close of friends. She just likes to fuck. Sometimes she just wants to blow me. She asks if I was a blow job. I always say yes, sit down and watch her. she is pretty good for a girl her age. She gives me these little half smiles then sucks me off.

She never seems all that happy when we fuck. It's very matter of fact. The only time she seems really happy is when she's talking about her boyfriend. When her boyfriend is coming to get her she tells me about it and gets all excited to see him and tells me about their dates and how much she loves him and how they are going to get married and shit like that then says something like, he'll be here soon wanna fuck??

I mean I love it but I don't get it.
