Jeff knew what he wanted to do, he would trade brains with his father, thereby switching their bodies. Jeff took note of the fact that his dad was in the master bedroom alone (he was divorced after realizing his sexuality), watching tv. Now was the perfect time to switch. Jeff set the transformation on a five minute timer, and used the time to hide the cronivac program and put on his swim class speedo, a nice surprise for his father after the switch.
The timer went off and instantly Jeff's brain was hard wired into his built, hairy, father's body, and his dad was inside his skinny, smooth teenage body. The fun was about to begin.
Jeff jumped out of bed, now in his father's body, and quickly closed the door and locked it. Throwing off his dad's white t-shirt, he left the welt built daddy in nothing but a pair of white briefs. He admired everything about this body, firstly his dad's package cupped by his briefs. He cupped it with his hand feeling the erotic rush of exploring his father's body. He instantly popped a hard on while doing this a grabbed his new dick while taking in the sight of his father's muscles and perfectly hairy chest. He let out an almost girlish moan so he could watch his father's body be submissive. See a "fuck me" expression on his dad's masculine face drove him wild with lust. He wanted to share this expression with his new "son"...
