Two puberty granddaughters forced the uncle to run out of spermTwo puberty granddaughters forced the uncle to run out of sperm. My two daughters, the same age as my daughter, came here for the summer holidays. One day, my wife and children visited my grandmother. Her two grandchildren constantly challenged me, making me unbearable. Those two days were a very happy time for me, two days that were sweet, innocent and very important to me.
