The third one

The thrid girl answer

"A very small one"

That comment make you blush harder.

"Indeed, now is probably at 2 or 3 inches. But the tiny state of Mark's penis may be due to exposure to cold, which causes a men penis shrink." Ms. K said

That was really embarrassing. All the four females at the room saw your shrunked penis, and mock you for that.

"But the penis culd return to the normal state by softly caress it..." Ms. K says.

Saying that, Ms. K starts to stroke your dick. That makes you start to feel some degree of excitement in your dick, and very fastly, you have a erection.

"What I perform in Mark was a masturbation, that guys and girls usually do when they're sexually aroused. Since I'm masturbating him, Mark have erection, that occurs when too much blood flows to penis, making it harder and bigger than in its flaccid state. Now, we will measure Mark penis. Who wants to do it? Or you want that I do it?
