Use them to rub one out

Normally, you wouldn't do something perverted like this to a woman's property, but since they're abandoned, you don't think anyone would mind. In fact, chances are the original owner is infected, and would probably be very happy you're doing something like this.

You sniff them. Even though they look new, there is that unmistakeable aroma of human use. They're not stained thankfully, but they do bear the smell of a cunt and ass. You look around one last time to see if you're alone, just in case. You unbuckle your trousers and scoot them down around your ankles. Your cock strains against your underwear. You free it from its confines, letting it breathe. It stands tall and proud, twitching. The cool air feels good against your skin, and it sends shivers up your spine. You wrap the green panties around your shaft, giving yourself short strokes up and down. The synthetic material is smooth and soft, if perhaps a little scratchy here and there. But it's not the panties themselves so much as the idea of using panties worn by a woman that's getting you off. Otherwise it's like a normal fap, which is still nice. You bring the bra up to your face, snorting the sweaty residue left behind. You feel a little ashamed in yourself for doing something so perverted, but... fuck it, who cares? It feels great, and you feel yourself getting more excited.

It's not long before you tense, jacking your meat furiously, and you cum all over the panties like one would on a crumpled tissue. You gasp, as the feeling is more intense than expected. After taking a moment to breathe, you take a look at your handiwork. Streaks of cum drip off them, the fabric off-color and moist. Too bad that whomever left these here won't come back for them, as the thought of them accidentaly putting them on all cum drenched makes you hard once again. You would definitely want to see the look on their face once they realise what's been done. Maybe they'd frantically pull them off, throwing them away. Maybe they'd leave them on with a smile on their face and a swing in their hips... Ah but no time for daydreaming.

You put your trousers back on, and ready yourself for what may come.
