had the funniest reaction from a 17 year old last week. In the car driven her round after school n she decides to reach over n start stroking my leg, i half bar up so she unzips me n slides her hand in, her tiny hand is so smooth n soft i get full hard in a couple of minutes, all the while shes got her mouth wide opening, totally amazed at how my cock grows n grows n grows. She then says at close to full hard erection (21cm) ''your bigger then the handbrake, if you keepin goin you'll be bigger then my forearm, wow its gunna be like getting fisted with a dick''
