Jeff's dad, a 50 year old buff hairy and handsome man named Jack, walked into Jeff's room and was absolutely shocked at the sight of his son, who now had his old dick in his mouth and a vacuum where his dick belonged!
"Jeff, what is going on here??" Asked his father.
Taking his dick out of his mouth and resting it on his bed, Jeff explained about the chronivac, and how he had traded out his dick for the vacuum to see what it was like.
Jack reprimanded Jeff, saying that it was dangerous to use the Chronivac without knowing the potential consequences. "And to teach you a lesson, I'll be confiscating these," said Jack, taking his son's teenage dick and balls from where they had sat on the bed.
Jack could hardly believe his luck as he headed for his room. He had his cute son's actual junk in his hands and could do whatever he wanted with it! Upon reaching his room he stripped off all his clothes and put on his favorite jock strap.
"Time for some father/son bonding," said jack to Jeff's genitals, putting them in the jock with his much bigger member. He could feel his son's soft young member respond to his own and grow from the contact. His jock was so full with him and his sons parts and he stared at the huge bulge the jockstrap displayed in his mirror. He gently rubbed them both together until he felt his son's dick cumming on him, which in turn made him moan and cum as well
