Take the long route

I decide that I might as well keep going, so I keep pedalling until I reach the viewpoint that Millie suggested, and it is amazingly beautiful there, so I put my mountain bike down on the grass, and sit in the shade and relax and look out over the valley below for a good 15 minutes, just enjoying the view and catching my breath after the lengthy ride up there.

I then pick up my bike, and ride back to the cabin, and the ride back is quite a lot of down hill riding, so I enjoy it but when I finally get back to the cabin a bit more than an hour later I'm quite sweaty.

I push the bike around to the back of the cabin, and as I turn the corner to the back I stop in my tracks. Millie is laying on one of the sun loungers next to the pool, and she is topless, her big tits glistening in the sun from her sweating lightly in the heat.

I just stand there and stare at her for a while, feeling myself growing hard, but then Millie notices me and gives me a smile and waves to me.

I wave back, still standing frozen in my spot, but Millie makes no move to cover herself up, instead she shifts to laying on her side, giving me an even better view of her big tits.

I manage to snap out of it after about 10 seconds, and push my bike up to where Millie is laying, using the bike to cover up my erection.

Millie smiles at me as I approach her, and when I am standing in front of her I stop and mumble something about how nice the bike ride was, doing my best not to stare at her big tits.

Millie shifts her body a bit so she is at a 45 degree angle, improving my view of her breasts even more, then says:

"See anything you like?"

Then after a pause of about a second she adds:

"During your bike ride."

Then she smiles at me.
