Denni O has a shtick: She's an old broad with a huge pussy. And her thing is to stuff extremely large sex toys inside of herself.

In the 50th edition of her series, she tries out a new dildo that supposedly is more lifelike than ever. But she ends up replacing it with her tried and true big black monster dildo. And when a dude with an above average size cock steps in to fuck her, his dick simply looks tiny in comparison.

One major Denni O selling point is that she wants the viewer to see what's inside a girl. She pries herself apart with both hands. And later, after the dude nuts inside of her, she sticks a glass object in there for the gynecological study.
