Millie comes out of the swimming pool

Millie splashes around in the pole for a little while to cool down, but after a few minutes she climbs out of it completely wet and looking very sexy. Her nipples are pushing against her bathing suit, and I feel myself growing hard at the sight of this, so adjust how I am sitting so that Millie cannot see the growing bulge in my swimming shorts.

Millie slowly walks up to where our sun loungers are, she grabs a towel and starts drying her hair, her massive breasts moving as she moves the towel around. Millie catches me looking at her big tits, but does not get mad, just smiles a mysterious smile and looks down at my crotch briefly. She knows my cock is hard! I panicky think to myself, but Millie does not get annoyed, instead she again smiles at me mysteriously and takes a seat at her sun lounger, glancing over at me and saying:

"Matt, don't be shy about that, it is very flattering that you react to me that way."

She then closes her eyes and lays down on her sun lounger.

I want to say something, but what?
