Futa with a Large growing cock

In the end he decides to give her a mostly normal penis with testicles, but with a few extra changes to make things interesting. When ready he started "I wish that Sarah was born a futanari, with most of our history staying the same except for the fact that Sarah has a penis and balls along with her vagina, Sarah's cock was allways large and by the time she was 19 years old had reached 14 inches long with large tennis size testicles, Sarah is also taller and stronger because she is a futanari, When Sarah got to the age of 23 years old she went to her doctors because her cock and balls had not stoped growing with her cock reaching 17 inches long and her testicles growing past the size of tennis balls. Sarah was diagnosed with a very uncomon disease that only shows up in futanari that causes there male parts to keep growing through out there lives but that the growth would slow down after her 28th birthday."

After making the wish and finishing jerking off Tom went to be sliding in next to Sarah excited to see the changes in the morning
