I decide when we stop my pet

As your orgasm begins to subside, she notices that you are remaining lodged in her quivering MILF hole, rigid as ever. Leaning in as far as you can, you say softly, "I'll say when you've have enough, you're nothing more than a set of holes for me to violate at my will. And," with a grab of her hips a slight backing out and a violent thrust in, "you will take more until I... am... done".

The MILF looks over her shoulder as far as her swollen body allows with a tinge of fear in her voice, "Please, no more, if you cum anymore I'm worried I wont return to my normal shape. Please consider what this would do to me!".

"Oh my wonderful pet, that's the idea, for so long, I have had to resist really cutting loose in you or anyone, to really give 100% is my goal. It won't be immediate, but I believe you are the prime subject for my training program." You reach forward to carress the stuffed MILF belly. "To stretch you more, to increase your capacity beyind your dreams. When I have finished, you'll be nothing more than a cum filled waterbed for me to rest on nightly. Likely we will need to seal you up a bit during training, we wouldn't want any leaks slowing your progress."

Being behind you are unable to see the horror speading over her face at the thought of becoming a nothing more than an ever expanding cum bank for this virile, young man.
