“Shame on you Ned!” Said Winston, “Fucking my body mere minutes after I had traded it away to your son. That’s your own father’s body!”
“Dad,” Ned started, “I had to grow up in your shadow. You were always more muscular and manly than me, and my own friends always thought of you as the hot one, even when I was in my prime. But that’s not your body anymore, it’s David’s. He can decided if he wants to let me explore it, or fill it with seed.”
“Why you dirty little pervert!” Said Winston, aghast.
“No, I believe you’re the little one now, dad,” said Ned. It was true, Winston looked down at his skinny teenage body and for the first time since the swap he could appreciate everything he had just given away. He looked at his former body in all its glory. It was so muscular and hairy, and sweating from being fucked. David made awkward eye contact from inside that body and felt so exposed with his dad’s dick still inside him and his own little grandpa dick on full display for its former owner.
“And if you hadn’t noticed, you’re in my son’s body for life. That makes you effectively my son. Now go to your room and jerk off like a normal teenager. Daddy and grandpa have to clean up their mess,” Ned said to Winston. He then kissed David passionately. David’s little dick twitched.
Grandpa Winston stormed out, mad as anything. He was in disbelief at how shamelessly Ned and David were enjoying his ex-body. But what could he do? Legally he couldn’t tell adults what to do. And now he was his own son’s son. He worked out to take his mind off of things. His sixteen year old body had lots of energy but the strength hadn’t developed yet. He was so frustrated with the loss of his body that he fell asleep at only 8pm.
