Tying for her Curves on Halloween

This curvy angel brings out scary feelings in me.
Because she makes me want to act like the devil with her.

My dad is old man Morgan.
He owns the Morgansboro mansion, and practically the whole town.
Every Halloween he turns it into a haunted house and throws a ball.
It’s not just any old Halloween party though.
It’s a place where billionaires can buy whatever they want.
They have auctions for curvy women,
where they bid on her very first time.
And sometimes there’s a tie.
I’ve never wanted anything to do with that kind of debauchery.
But when I see voluptuous Michelle on stage,
dressed in a sultry dark angel costume,
I can’t help but want to participate.
It turns out I’m not the only one.
I could never share this burning passion I have for her, though, right?
But if that’s the only way it can happen,
it will be worth it, for just one time.
Unless we all end up liking it a little bit too much…

Is this just a Halloween hook up?
Or have all three of us found our happily ever after with Michelle?
