Mistress Shows Up To The Wedding In A Wedding Dress

OMG, This is INSANE

Imagine you had a side piece.  For some of you, well... it's not too hard...

Now imagine you're getting married... But your side piece isn't taking it so well.  She's tried to get you to stop it.  She's tried to get you to marry her instead.  She'd tried everything... But you're going ahead with the wedding to your full-time girlfriend...

So... she does this:  She gets a wedding gown of her own and shows up to the church.
