I know we haven't been getting on well lately but after todays argument I thought I would try make it up to you by going out and buying a sexy outfit to wear for you since you say I'm boring in the bedroom and vanilla as fuck all the time, I thought I would try and make an effort. Just ignore my identical Step-Sister though if she starts annoying you, I can't stand her and I know you can't either. She is such a slutty skanky whore compared to me isn't she but I know you love me and have no interest in a skank like that do you...
Until I walk in from picking out a sexy outfit to wear for you and I find you BALLS DEEP inside my Identical Step-Sister, what the fuck? I thought you wanted to be with me and not my slutty whore of an identical Step-Sister. You now have to pick which one you want because you can't have us both... can you?
