Growing up you had the biggest crush on your big sister’s best friend, your one time babysitter. But that was years ago and now the Bestie has decided to start a family on her own courtesy of the new fertility clinic in town - the same clinic YOU have been making deposits at to earn money for college.  Against all odds, YOUR sperm sample has ended up being HER donor and her body knows what neither of you do, yet. That YOU are her baby Daddy. You may not have knocked her up the old fashioned way but she’s about to stake a feral claim on your cock. I had so much fun going completely feral in this script by the incredibly talented The-MYLF-Man! rosey <3
