The other night me and my ladyfriend were getting into our foreplay when she grabbed me by the balls. This is normal for us because I really enjoy having my sack pulled on and my nuts stretched a bit. She wraps her hand around my scrotum above my balls and gently squeezes and tugs. She decided that this time she was gonna play a little rougher and gave them a firm but slow tug that forced me down to my hands and knees. The mix of pleasure and and a hint of pain got me very excited. When she let go and I sat back up, we both noticed that my cock looked much thicker and felt even harder than usual. Needless to say she insisted that I fuck her immediately. Has anyone else expiereince a harder, bigger erection after have your balls handled?
