"Nothing"

I reply, feeling myself start to blush. Millie gives me a long lingering look and then smiles at me in what I could interpret as a seductive smile, but maybe it is not, then she looks away.

I realise that the moment, if there was one, is gone, so I sit down on my sunlounger, taking the opportunity to look at my step-mom's big breasts pointing at the sky for a bit longer than I should, then I lay back and close my eyes.

I feel an intense need to jerk-off, but I know I need to think up some sort of reason to go in the house, or do I? I ponder whether I should just get up and walk into the house without saying anything, then quickly steal a glance at Millie's big tits. She has her eyes closed and her breasts are slowly heaving as she breathes. How I would love to get my cock in between them, or even just to squeeze them a little bit.

I need to do something to relieve the tension I think, then suddenly I find that I have stood up and Millie opens her eyes and looks up at me, asking:

"Where are you going Matt?"

"Eehhmm... I need to go... to, eehhmm... wash my hands."

I hear myself stutter, then quickly, without looking Millie in the eyes I walk away and go through the patio doors into the cabin. Once inside and partially out of sight I risk a glance back at Millie. She's laid back on her sun lounger and closed her eyes. I let my eyes linger on her big tits for a few seconds, squeezing my cock through my shorts, then with hurried steps go to my room.

Once there, I head for the ensuite bathroom, and as quietly as possible I release the hatch holding the frosted window closed then slowly push it upwards creating a crack about an inch high. I pear through it, and think to myself: bingo! I can see Millie from here.

Standing slightly hunched over I don't hesitate but pull my cock out of my shorts and start to stroke it while watching her.
