Offer her your ass

You wink at her and ask "Well, how quick can you cum in this?" turning and bending over to show off your pert ass. Yuli grins at you wickedly in response.

"A challenge eh? Lean against that wall over there and I'll show you how quick I can be."

You dutifully lean against the back wall of the inn as Yuli hikes up her skirt, revealing a cute five-inch cock. She walks up behind you and shoves it in hard. While she isn't huge in the dick department, she isn't going easy on you, your teasing inspiring her to fuck you hard and fast.

"Oh yeah, you like that baby?" Yuli asks, grabbing your hips roughly.

Between your pants and moans you gasp out "That all you got?"

"You little slut!" Yuli smacks your ass with one hand. "You like it rough do you?" She redoubles her thrusting, roughly dominating your ass in the alley. One hand grips your waist firmly, while the other reaches around to grasp your cock. She begins to stroke you in time to her thrusts, bringing you both quickly to the brink of orgasm.

She slams deep into your ass a final time, and her dick hits something deep inside you, you moan and begin to shoot your load all over the alley wall. At the same time you feel Yuli's cock twitch and spurt inside you. She moans as she deposits her load of cum in your ass, then slowly withdraws as you both pant for breath, winded by the high intensity fuck. You're not sure, but this probably counted as an aerobic workout.

"Thanks!" Yuli says, giving you a quick smack on the ass as she rearranges her skirt. "Come flirt with me any time you want!"

She makes her way back into the bar with an extra pep in her step, as you catch your breath and slowly fix your pants. Looks like you made a friend!
