When Mikey and Sam went to the arcade they came across a 4 year old kilf Emma, the hot bitch fuck who one day will be a slut with huge tits (knockers). After their encounter with the rare kilf they immedietley had an everlasting bonner which Emma said she will blow when she gets at least to ten years old. Pretty young for a slut!!!
