Watching Millie in the shower

I do as Millie says, and watch her through the glass walls of the shower cubicle. She acts like I am not there and continues with her shower, while I am standing outside it naked, my dick rock hard.

Then Millie looks out through the glass at me, and pushes her tits against the glass door. Her tits are so big, so seeing them flat against the glass is incredibly sexy. I reach my hand out, and touch the glass through which I see her tits being squeezed. Millie smiles a naughty smile, then pulls back from the glass.

She points at my dick, then moves her hand like she is jerking a dick. I am not sure what she means, so I look at her with a questioning look and point at her. Millie shakes her head and points at me. She wants me to stroke my dick.

I do as she says, and slowly start stroking my dick while watching Millie's naked body in the shower. Millie's eyes are transfixed on my dick, and she starts touching her pussy. Our eyes lock, and she mouths the words: "Do not cum".

She then turns of the shower, grabs a towel from the rack next to the shower and pulls it over the glass door into the shower cubicle, and starts drying herself up. I am incredibly horny as I watch her, and am still stroking my dick.

Millie wraps herself in the towel and steps out of the shower cubicle. My hand reaches out towards her, but she waves her finger back and forth in front of me and says:

"Not yet, you shower first." Then walks out of the bathroom.
