Katie goes round to her neighbours house and is very happy to hear that his wife is out. She talks about how much she loves watching guys with big dicks jerking off and squeezing their balls. She strips and gives him a JOI before taking over with her hand. She loves feeling his big penis and hard full testicals in her hands. He explodes all over her tits.
This was originally a custom which is very focused on ball squeezing and using the terms penis, nuts, dick, testicals, ejaculate, semen and spunk.
