Nope. She makes you wait

Your brother’s wife grins up at you wide enough for you to take your eyes off your cock smashed between her fun bags. “Not yet big boy. I want those balls fuller.”

She stands up and your hard cock slips out from her glorious tits.

You were so close! You’re ready to beg for it. “You’re a tease!” You cry even though it sounds pathetic to call someone who just let you tit-fuck in a public fountain a tease.

She giggles and struts over to her clothes piled on the ground. She calls back, “It just make you make me more.” With her back to you, she strips off her wet panties and bra. You see her big tits swing from the back as she puts her dress back on. She ties up her hair.

She spins back to your shocked face, and says, “C'mon I’m starving. Let’s go eat.”

Dick in your hand with full balls, you’re afraid you missed your chance to blow all over her tits. The only thing giving you hope is that drunken look in her eye that says she’s hungry for more than just food.

You leave your wet underwear in the fountain. You pull on your pants and button back on your shirt. You hurry before the police show up. Somebody had to have seen you fucking those big titties.

Your sister-in-law stuffs her panties in your pocket. “You’re so much more fun than you brother.”

We make it back to the restaurant, where your angry wife is waiting for you.

“Where were you? Why is your hair wet?”

“Waiting for you to get back. We took a walk.”

She knows something’s wrong. She just can’t prove it yet.

You can’t take your eyes off your smiling sister-in-law. You both share a secret and aren’t wearing underwear. She sits across the table from you and your wife.

When you’re ordering, you feel her reach out under the table and rest a foot in your lap. It starts rubbing the smooth fabric of your slacks on your cock. You start to grow.

Your sister-in-law giggles.

“What’s so funny?” Your wife asks.
