After an hour, Nate was still jerking off into Jeff. He had just finished the 5th load, when he had a thought. Maybe I could make it so that the only jockstrap Mom will see will be '1B'. He looked at the time and figured he had about an hour more before she would come up here to change Jeff back. He quickly got up off of Jeff's bed and sat at the Chronovac, pressing his reawakened hardon into Jeff again.
The closest thing Jeff could compare what he was feeling to, would be like being drunk. Jeff was drunk on his little brother's cum. Idly he felt himself being moved and he started to come back to himself. Yet right as he was on the verge, he felt his brother's cock press back into him oozing pre.
Nate quickly changed it so that Subject 1B would be seen as the "real Jeff" by his Mom and everyone else, with the exception of himself and Jeff of course. He also made it so that she would forget about the Chronovac right away. He smirked and reached down and grunted as he jerked another load right into Jeff, further fogging his mind.
Nate looked at the time and saw that he only had 15 minutes before the dryer would be done. As he kept an ear on the door, he opened up Subject 1B's file and changed it so that when it was changed into Jeff it would do 3 things. First, it would transfer the Chronovac to Nate. Second, it would then forget about the Chronovac. And third, it would proceed to live as Jeff, until he decided to change Jeff back.
Well, if he decided to change Jeff back.
As he clicked Enter, he heard his Mom coming up the stairs. So he quickly powered down the computer after seeing the changes were complete, and he hoped out of the chair and walked towards the door. He grabbed a book that he saw, in order to fool his Mom, and not a moment too soon.
"What are you doing in Jeff's room," she asked quickly.
He raised the book to show her, "Just grabbing a book to read a little bit before bed tonight, thought it would be a new change of pace."
Her gaze softened and she said, "Alright but remember to give it back." And she rushed him out the door. Before it shut Nate caught a glimpse of the clothes basket in his Mom's hands. Right near the top was the jockstrap.
