Chapter 1: Outside the stall

Eva pushed open the stall door on shaky legs, her mouth still full of the stranger’s thick, salty load. She had swallowed every drop, greedily sucking him until he emptied himself down her throat after he made her cum hard. Her jaw ached deliciously. A faint sheen of saliva and cum still glistened on her swollen lips. Her panties were ruined, pushed to the side, and her pussy continued to throb and leak from the intense orgasm he’d given her with his hand.

She stepped toward the sinks, trying to steady her breathing, when she saw her in the mirror.

A hot auburn-haired woman in a floral sundress stood frozen at the counter, eyes wide. She had clearly been in the next stall the entire time. A gold wedding band gleamed on her finger.

She turned slowly, her cheeks flushed. She couldn’t hide the way her thighs were pressed tightly together or the rapid rise and fall of her chest.

“I… heard everything ...” She whispered, voice husky. “The way you were moaning around his cock… the wet sounds when he fingered you… and then you swallowing him like that. God, you sounded so eager, it was so hot girl, i got wet...”

Eva’s face burned bright red. She quickly wiped the corner of her mouth with her thumb and licked it clean without thinking. The taste of the stranger’s cum was still strong on her tongue. In the mirror she looked exactly like what she was: a married woman who had just finished sucking off a man who wasn’t her husband.

“I didn’t know anyone else was in here....” Eva murmured, embarrassed but undeniably turned on by being caught. She pressed her thighs together, feeling fresh wetness slip down her skin.

The woman stepped closer, eyes flicking from Eva’s messy lips to her flushed neck and down to where her skirt was still slightly crooked.

“I’m Casey” she said softly. “Married… two kids… and I’ve never done anything like that.” She let out a nervous laugh. “My husband’s been traveling for weeks. I was touching myself in the next stall listening to you. When you started gagging and moaning I came so hard I had to bite my hand to stay quiet.”

Eva’s embarrassment mixed with a fresh rush of heat between her legs. Being watched, being heard, while she behaved like a total slut made her clit pulse again.

Casey bit her lip, clearly fighting with herself. “You swallowed it all, didn’t you? You let a complete stranger cum in your mouth and you drank every drop… while your husband has no idea where you are right now.”

Eva nodded, a shy, wicked smile breaking through. “He doesn’t. That’s part of what makes it so hot.”

Casey’s breathing grew heavier. She glanced at the bathroom door, making sure they were still alone, then looked back at Eva with raw hunger in her eyes.

“I’ve been fantasizing about this for months...” she confessed, voice trembling with excitement. “Sneaking away. Doing something dirty and risky. Feeling that thrill… that shame. Hearing you tonight pushed me over the edge. I’m so wet right now I can feel it on my thighs.”

She reached into her purse, pulled out a fresh pack of mints, and offered them to Eva with a shaky hand.

“Here… so you don’t go home smelling like cum,” Casey said with a small, conspiratorial smile. Their fingers brushed as Eva took them. The touch lingered a second too long.

Eva popped a mint and swished it around her mouth, still tasting the stranger on the back of her tongue. When she looked up, Casey was watching her with intense fascination.

“I think… I want to try it...” Casey whispered, almost to herself. “Not today, but soon. I need to feel what you just felt. I need to know what it’s like to be on my knees for a stranger.”

She took a deep breath, smoothing down her sundress, then gave Eva one last lingering look, equal parts nerves and determination.

“Thank you for… letting me hear that. You have no idea what you just started.”

Casey turned and walked out of the bathroom without another word, her hips swaying a little faster than usual, cheeks still pink. The heavy door swung shut behind her.

But as she stepped into the hallway, a secret smile played on her lips. Her heart was racing. Her pussy was aching.

For the first time in years, Casey wasn’t just imagining it.

She was already thinking about when and where she would make it happen.
