Wife’s Twin sister is an equally hot BBW. We must’ve annoyed my wife while cooking because she yelled for us to “go find some thing to do” after not finding anything good on TV, Wife’s sister closes the Door and Takes her clothes off. I asked what are you doing? She says “Well, she wants us to do something, let’s do each other. Wanna Fuck me real Quick big guy?” We fucked for a few mins before I finally found my Camera to Record. Wife still doesn’t know, she would be so pissed off that we did this.
