Family Makes It Better

Dear Diary,
OMG this is so crazy I don't know where to begin. Step-Daddy and Russel took turns having fun with Kate on the drive to Grandpas but I guess that wasn't enough for my step-sister. Apparently after they she let Gramps fuck her in the ass and he collapsed on the bed.
As soon as Step-Daddy picked me up we headed right back to Grandpas to console Kate. I started comforting her while Russel and Step-Dad took care of Gramps but instead of crying we wound up kissing and making each other cum. Step-Daddy and Russ walked in and joined us turning it into a family foursome.
Afterwards we loaded Gramps in the van so we could take him to uncle Dicks since he's away all Summer and said goodbye to Kate. A few hours down the road I was horny again and got step-daddy to fuck me. I know its weird but I thought I saw Gramps dick getting hard next to us.
