Throw away on the off chance.

I'm on holiday with my partner and her family, including her sister.

We've been out for the day, walking around and seeing the sights. Both sisters are relatively demure women, but her sister was dressed in workout gear all day, with all the figure-hugging goodness that entails. She's blonde, about 5'10, with these gorgeous mommy tits and a cute thick butt.

Everyone else just went out, getting changed into swimming gear and leaving me home alone to chill. Whilst they're out, I went to use the sister's en suite, as it has the only shower in the house. As I walk through her room, I notice those discarded workout clothes from earlier, neatly folded nearby - with some black lace poking out. Uh oh.

I couldn't help myself. Carefully moving everything else out of the way, I delicately peeled a plain, but distinctly small cotton thong out of those tight bottoms she'd been wearing all day.

I brought them to my nose and inhaled sharply. While not super pungent, I found a sweet spot, somewhere between where her asshole and pussy had been resting all day. I was hard in moments.

That sweet, tangy aroma drove me crazy. Clean-smelling but heady; not too strong, but unmistakeable. I took out my cock - which I haven't been able to 'attend to' in days - and stroked myself silly. If only there had been a second pair to wrap around it whilst I pumped, hard and fast, all the while inhaling deeply the scent of her cunt.

I tried to picture it: is it bald, trimmed, or natural? I have to imagine one of the first two, otherwise I'd have smelled her sweat more strongly after traipsing around for several hours. I wondered why she prefers thongs, when her sister has never worn them; does she enjoy the feel of the fabric cupping her more closely? Does her husband prefer them? I picture them pulled to the side while she moans, either being fucked or playing with herself.

I didn't know how much time I had, so I just went for it. After barely a minute, I came, hard.

After replacing everything, I went back about my business, but they're all still not back, and I'm tempted to go back for round two...
