Public nudity

You stumble out of the bar, your arm wrapped around her waist, more to keep your balance than any other reason. You walk down the riverfront. The breeze blows off the water and you can smell the diesel of the boats. You swallow back the saliva building up in mouth.

You see a fountain. Big enough that visitors throw spare change in it for luck. You stare at the splashing water and get an idea.

You take your arm off your sister-in-law’s waist. You take off your shirt.

She laughs, “What are you doing?”

“Going swimming. You gotta join me.”

She giggles. When she said something wild, she never imagined this. She follows the trail of your clothes to the fountain.

You stand in the water wearing only your underwear. You feel pennies between your tongue. You squat down and splash water at your sister-in-law. “C’mon I thought you were my partner-in-crime.”

“Okay, give me a second. This dress has a lotta buttons.”

You watch her undo various buttons on her conservative dress. She lifts it over her head and reveals her very progressive underwear. The black see-thru bra holds up her big torpedo tits. A black seam runs up the center of each cup obscuring your view of her nipples. You glimpse her areola through the fabric. She wears a black thong that has a wide lace band running around her hips.

She steps into the fountain and joins you. You can’t take your eyes off her tits when she bends down and gives you the perfect view of her cleavage. She splashes water up into your face.

You laugh and wipe the water from your eyes. “Oh that’s how it’s gonna be?”

You bend down and splash water at her. Her big bounce in her bra as she runs away from you. This water is pretty cold, if you get her tits wet, you could harden her nipples. You wanna see that for sure.

You try to creat a big wave but your drunk ass ends up falling into the fountain. When you get up, your wet underwear clings to you. The outline of your erection is visible.

Your sister-in-law halts to tit-jiggling stop and covers her mouth when she sees it.
