Grab something nice and thick. I mean really thick - this is not about comfort or pleasure. I need to test how much that pussy can take.
Put it on the floor, facing up, and lower yourself onto it. Good girl. Get it nice and deep.
Feeling stretched? I sure hope so. If not, find something bigger.
Now fuck yourself on it. Bounce up and down 40 times and rip that little cunt open. You can rub yourself too, and if you can get to the edge one more time, well, good for you.
