A member of the school system

You'd only just turned eighteen when you met him, and the end of high school has become nearly a reality.

That he was handsome was apparent. That he was older was obvious. That he had a large penis was a 'delightful' discovery for later, though his proficiency is with it might be up for debate. Nonetheless, you think about that dick alot. And him as a person too, of course, right?

It hadn't occurred to you, when you first saw him, that you'd be his girlfriend. Not an eighteen year old schoolgirl like you with an older man like him. Especially not with a person associated with the school system. Even if he was drop-dead handsome.

Perhaps it isn't important how it began, only that it's going to continue, one way or another, whether you're happy about that or not. The two of you can't officially be a couple, but does that justify how you can't seem to stop sleeping with other people while you 'date' him?
