i used to swim all year round, and immediately noticed in the cold winter months the balls would be incrediable stimulated by the cold, ( I even f*cked a fat chick with glasses.)..Its a medical fact sperm is increased dramatically and blood flow...Freeze those balls for a half hour with ice, and watch out thai cuties.....Belt your hand with a hammer every time you fail to come, and within a week you will find yourself flogging the eel over her face, the hand terrified its in for another serve!
