Yes, she encounters someone fucking

About ten minutes down University Ave, Izzy was passing a large structure on her right—the library, she thought—when she caught some movement from the corner of her eye.

Tucked into a little crevice against the wall of the building, between tall bushes and intricate stonework, were a pair of people. They were well concealed. In fact, Izzy realized, if she weren’t standing exactly where she was, they’d probably be blocked from view. It was a good thing for them too, as one of the people was currently brutally fucking his bent-over counterpart.

His hand clasped her mouth to keep her from making noise (which, judging from her giddy expression, she certainly would have been doing). The bushes concealed a good portion of the show, but Izzy could see the girl’s skirt had been hiked, and the hand which wasn’t silencing her was roughly groping an ass that jiggled with every rough pump.

Izzy felt her face go cherry red as she watched this scene, and her pussy started to tingle eagerly. She stepped to the side, momentarily losing sight of the rutting lovers, and began to circle around while avoiding their line of sight.

She found what she was looking for around the corner of the library: a closer view, and side-on, able to watch the point where thick cock met hungry pussy. As she crouched into position, peering around the wall, she felt herself start to drip. This was better than porn!

Biting her lip to keep herself from moaning, Izzy slipped her right hand into her leggings while the other slithered up beneath her shirt to start fondling a nipple. Her quim was already drenched, and as her fingers began to play with the slick folds, an electric feeling shot from it, making her knees weak. Izzy quickly started to imagine that she was in that girl’s place—that the feeling in her cunt was coming from being roughly used by a man, instead of her own hand.

It took precious little to make Izzy climax, and she soon felt an all-too familiar sensation building as she masturbated, spurred on by the impromptu sex show in front of her. Her eyes drank in the way his body moved, the drops of sweat on the back of his neck, the way his conquest's body trembled and shook as she undoubtedly came over and over and over again. Feeling her own orgasm near, and not wanting to end up with an embarrassing wet spot on her crotch, Izzy thought fast. She shuffled her leggings down over her petite butt, exposing her bare pink pussy to the world, uncovered by panties. Knowing that the splatter of her squirt could still be noisy enough to expose her presence, she quickly pressed herself against the stone corner of the building, so she was almost humping the brickwork.

The feeling of her clitty pressed against something solid was all it took to push the poor slut over the edge. With a dizzying rush of pleasure, she felt her little teen hole clench and convulse, a gush of clear girlcum dousing the grey stone wall and silently running down it in a slightly-sticky trickle. Suppressing an aroused whimper, Izzy ground her sopping flower against the building, leaving behind a dark stain of wetness.

From the corner of her eye, she could see that the male had bottomed out in his partner and was gripping her tightly, keeping his cock buried to the hilt as he leaned his head back. It seemed he was cumming too. The way the overwhelmed girl was almost collapsing from pleasure supported the theory that she was currently getting her womb flooded with hot cum.

Panting, Izzy pulled back from the stone she’d defiled, quickly shuffling her leggings back over her still-throbbing pussy. A little bit of juice might soak in, but that was pretty normal for her. Besides, now that those two were done… yep, they were looking to leave.

Izzy ducked back around the corner to break line of sight, though not before seeing a delicious waterfall of cum pour from the girl’s ravaged cunt as her beau pulled out. There was no condom, of course; such archaic forms of birth control hadn’t been a thing since Izzy’s grandmother’s day.

Izzy waited, huddled behind the wall, as she heard the two tuck their bits back into their clothes, then hurry away from the scene of the crime. They passed right by her hiding spot (the girl walking with a pronounced limp), but mercifully Izzy went unnoticed by both of them as they walked off down University Ave.

Izzy waited to the count of fifteen, then emerged, ready to continue on her own way. She spared a glance back over to where the pair of unknowing performers had been doing their deed, and—fuck… that was a hell of a puddle of cum they’d left…

She paused. She knew nobody would see her.

But, no, surely that was too much. Even for her. Slurping a stranger’s cum off the concrete ground, where it had spilled after leaking from the overstuffed cunt of a different stranger. Too much. Right?

Right?

As Izzy rejoined the sidewalk, turning to continue toward the ARC, she unconsciously licked her lips and found just the tiniest bit of slime that she had missed. She pulled the musky fluid into her mouth, trembled slightly at the pungent, masculine taste, then continued on her way.
