Standing up.

You offer your hand to help Sara stand up then you grab her right knee to lift up her leg. Understanding what you have in mind she places her hands on the tiled wall and the other on your shoulder for support. She looks at you with a mischievious smile, "Fuck me, Mark!"

"Yes, ma'am!" you salute and guide the tip of your cock to her pussy lips. You push your hips forward and the two of you let out low moans as her cunt slowly swallows your cock whole. Grabbing her wide hips you start thrusting, the sounds of flesh slapping against flesh mixed with splashing water.

"Ooooh yesssss.... Fuck me!" she cries. "Harder, Mark!"

"I'm trying," you groan, slamming even harder into her cunt.

"Uh! Uh! Uh!" Sara grunts repeatedly as her tits jiggle violently with every hard thrust of yours it absorbs.

"Cum for me, babe," you growl.

"OOOoooooh fuuuuuuck yessssss!!!" she screams as her pussy muscles spasms around your pistoning cock. You stop thrusting momentarily to savor the sensation of her pussy massaging your cock.
