Going outside to see Millie

I walk outside to the patio area, and I can see Millie sitting in the shade in one of the sun loungers by the little swimming pool. She has taken off her blue tank top, so is in her daisy dukes and a pink bikini top. Millie sees me coming out of the house and shouts:

"Hey Matt!" And waves at me.

I walk over and plunge down in the sun loungers next to hers, and she says:

"A bit too hot to walk around and show you the area around here now, so should we just hang out here for a while?"

"Sure, am a bit tired as well, so could do with a bit of relaxing myself." I reply.

There is a newspaper on the table between the sun loungers, so I grab it and start reading it, while Millie is flipping the pages in some magazine.

I am peeking at her big tits bulging out of her bikini through the corner of my eye, and then Millie picks up an ice cube from a bucket next to her, and runs it over her face, neck, and then through the valley between her big tits, on the side of her tits, and then over her nipples. It might just be my imagination, but to me it looks like her nipples harden when she runs the ice cube over them.

She is doing it to cool down, but I wonder if she is also doing it to tease me. I feel my cock getting hard, so I fold my legs up so the bulge it creates in my pants won't be visible to Millie.

Her running the ice cube over her tits has made me so horny that I have forgotten to be discrete when I look at them, so my head is turned to the side and I am laying there looking at them. Then Millie suddenly turns her head and looks at me, and says:

"Yes?"

She is still rubbing the ice cube on her tits.
