Creampie before family party! If my sister knew…

Today the family announced they were coming for coffee again. My sister’s husband was early again, although I think that was intentional and he had his eye on my hot fat ass in my tight leather leggings! The horny guy is out to have me again because my sister is a pretty prudish bitch. She only lets her husband get close to her once a month, so I didn’t have to be asked twice for a quickie and held out my bare pussy. Oh my God, the filthy slut squirted her whole load of cum in my pussy! If my sister finds out about this, there will be a real family crisis again! Hehe, I’m really mean, aren’t I? Are you allowed to do something like that?
