Eric pulled out from kiss as he went to chronivac and started typing. "What are you doing" asked his mom as he answered "you'll see" .
He accepted changes and came back to her as she looked around trying to see what changed. She didn't see anything different. "You might be wondering what's different now, sit on the bed and I'll tell you during sex."
Lisa did that and Eric started eating her boob making sure to suck on it and get the most milk he can. Lis felt a shock in her brain as every lick caused more milk
"I made you way more submissive."
Lisa gasped as she felt she couldn't even speak now if he didn't allow her to. What a horrible thing to do to his moth... girlfriend and after all the sex they've been having.
"More than that if you orgasm you will stay like this forever. The rest of your life willl be spent as my loyal sex mommy. Lovingly taking my loads day in and day out."
He sucked on her breasts a bit more making sure to make her nice and wet. Lisa was already getting turned on but she clenched her muscules trying hard not to seal her fate.
"That is of course if you want me to cotinue. I would never do anything against your will." he stopped and moved away his dick fully erect as the smell hit her nose, it smelled amaizng and she needed it. But she couldnt , it would be the end of her.
"If you play with yourself and cum I'll fuck you. But you have to do it in the next 10 minutes, otherwise you'll turn back into my girlfriend."
Lisa tried to stop her hand going to her crotch but she couldn't the idea of his dick was too much to handle.
She reached and took a dildo from behind her pillow, pumping it in and out of herself.
The orgasm hit her strong, half of her mind screaming noo as the other loved it. Now her whole life was sealed forever.
"Good girl. Here's a treat." Eric jerked his dick onto her boobs glazing them and forming a little puddle in between.
She licked as much as she could enjoying the taste from dick she personally made. It was so thick and smelly but she loved it. But she was a bit sad he didn't keep promise and didnt fuck her instead.
Eric goes to wash his dick in bathroom and leaves the computer on as lisa makes a plan.
