As they were going at it Tim was glade he had made the other changes on that Chronivac program so that no on in the house would notice what was going on in Jess's room since her new sex drive had made her a totally sex crazed demon in bed. It seemed to Tim that Jess wanted to try every position she know so he was glade he had given himself the extra stamina he now had which allowed him to give her a number of orgasms.
As Jess was pretending to be a cow girl breaking a bronco riding Tim's new bigger member he was mesmerized by her new breasts and could not help but think of what they would look like if they were filled with milk.
The two of them went at it for a few hours until they were totally exhausted and then they fell asleep in each others arms.
The next morning........
