A big black dildo

Your eyes widen as you see what your wife is holding. It is a large black dildo, about as long as your arm and very thick. You swallow.

"When did you get that?"

"About a month ago." Holding the monster with two hands, your wife begins to rub the head of it against her clit.

"Why... why is it so big?"

Your wife stops rubbing her clit and looks you dead in the eye. "I felt like a bit of variety."

Ouch. Your wife exhales heavily, and you notice the tip of the fake cock is shining with her wetness. Thick veins run up the sides of the rubber cock. It really is massive.

Your wife snaps her fingers. How long were you staring at that cock for?

"Stop gawking. You can make yourself useful."

"Yes mistress." The word escapes you. "What can I do?"

A small smile appears on your wife's lips.
