"Yes"

I reply, adding after a bit of hesitation:

"Of course I have."

"Then why are you so nervous?" Millie asks, squeezing my hand so that it is squeezing her breast.

I don't reply, but I work up the courage to squeeze a bit more on her breast, with Millie looking up at me with an amused look in her eyes. We keep going like this for a while, then Millie says:

"Matt, they will not break, fondle them."

She arches her back, making her breasts point out at me even more and then closes her eyes. I put my second hand on her other breast, and start to fondle them both. I keep this up for a little while, then Millie shakes her head and opens her eyes, saying:

"What's the matter Matt?"
