Patrick had enjoyed watching Jeff's transformation and was rock hard. He decided to look over the Chronivac's features before he dealt with that. He discovered that a reality change was in effect for the last change but Patrick and Jeff would still remember the old reality. The device said that Jeff had been part of an experiment that had turned him into what he is now, but because he still acted like himself, except for being more suggestible, he was allowed to return home.
Patrick liked the experiment idea but wanted to change the rest of it but this time without Jeff being aware. Patrick made it so that Jeff was adopted by Patrick's Dad who had been the head scientist (which was much of a stretch as he has a degree in biology) after the experiment was over to serve as his son's pet. Jeff was completely loyal to Patrick and would do whatever Patrick said. Patrick also made it so that Jeff was sexually attracted to males.
Next Patrick decided to make some changes to himself. He made his dick 12 inches long and his testicled as big as grape fruits. He decided not to change anything else as the idea of dominating such a large being as Jeff with his short, scrawny frame turned Patrick on even more. Patrick just had one last change in mind. He decided to make it so that certain words would change how Jeff acted in relation to other people. Whilst he would always be submissive towards Patrick, that may not be the case with other people.
Patrick submitted the changes and nearly lost it as his dick expanded. But he held on as he wanted to put it to use on Jeff straight away. He walked up to Jeff and woke him up. He told Jeff to start sucking whilst pointing at his dick. Jeff complied and Patrick's dick was enveloped by Jeff's animalistic muzzle. Patrick was lost to the ecstasy of the blowjob he was getting from his former brother now pet. He didn't let it go on to long though. Before he blew his load in Jeff's mouth, Patrick told him to turn around. He lined his dick up with Jeff tailhole and drove it in until he was fully hilted inside of Jeff.
Patrick began thrusting with reckless abandon, enjoying every moment of pleasure. He found himself cumming inside of Jeff as Jeff launched another volley of his own. Patrick and Jeff collapsed with Patrick still inside of Jeff. He wanted to do more and couldn't wait to experiment on...
