The natural thing

Jake was a little too confused by the panties thing to even be turned on by it, but seeing the naked body of this woman he spent most of his puberty obsessed with--in pictures taken specifically for him, no less--has his cock throbbing almost immediately. He hurries off to the bathroom, passing Eric in the hallway as he goes.

"Freaking pervert!" his friend sighs after him, but Jake's got tunnel vision at this point. He doesn't give himself a moment to think; he just locks the bathroom door, drops his pants, and wraps that blue cotton around his shaft. He's never jerked off with panties before, but he's used socks to catch his cum a few times; this feels surprisingly similar, but the fabric is softer and still slightly warm from her body.

The more exciting part of the process was the material he had to work with. No one's ever sent Jake his own personal nudes without him having to pay for it, so all his masturbatory fantasies hit that much harder because he knows that she really was thinking of him at the time. Those legs are spread for me, he thinks. She's offering me that ass.

Then he can't help but imagine how those pictures were taken, Janie exposing herself and posing like such a slut while her own brother held the camera. But they aren't Eric's pictures. They're Jake's.

He cums hard to that thought, jizz dribbling through the panties and dripping down to the bathroom's tile floor. He wipes it all up, using the most precious garment he's ever held as a rag, and almost tosses the panties away into the dirty laundry before he has a much hotter idea.

On his way back to Eric's room, he hangs the sticky soiled underwear over Janie's doorknob. As nice as she was to let him borrow them, it's only polite to return them now that he's finished. With a smug smile and a healthy post-orgasm glow on his face, he goes back to see Eric.
