Fuck her gorgeous tits.

I pull myself up on edge of to pool and look down at my sexy step-sisters tits bobbing just above the water. I feel my cock throbbing as I enjoy the view. I want those gorgeous melons wrapped around my cock.

Finger to my temple "Put my cock between those gorgeous tits and stroke it sis"

"mm I would love to have your big cock between my tits." She stands up between my legs grabs my cock and pushes the tip between her tits.

"You like my big tits big bro? mm seems like your cock does." She strokes the shaft of my cock as she smears some of the pre-cum from the tip of my cock between her tits. Then she raises her body up, presses her chest into my stomach looks up at me and licks her lips. Still stroking she positions the tip of my cock under her tits and drops down pushing my cock between her breasts under her bikini. I see the head of my cock appear in her cleavage and feel the vibration in her chest as she moans.

"I think we need a little lubrication." She says with a wink. She takes the head of my cock and sucks it into her mouth with her poutie lips. I feel her tongue circling the head of my cock and I can feel saliva building up in her mouth around my cock. She opens her lips just enough to push the saliva out and I watch as it drips down my cock and between her tits.

She looks down and moves her body up, my cock slides down out of sight between her breasts and then back up again. Her cleavage and my cock now wet with saliva.

"mm that's much better." she starts moving her tits up and down on my cock. It's warm and slick, she pushes her tits together to make it tighter around my manhood as she strokes me with her breasts.

I lean back on my hands and look down at her as she fucks me with her tits faster and faster. She positions her mouth right above so the head of my cock slides between her pouty lips every down stroke. Watching her service me is incredible and feeling her suck the head every stroke is driving me crazy. Every time she moves up, my cock audibly pops out of her mouth and then disappears between her large perky tits.

I know I'm not going to last to much longer with my beautiful step sister doing such a porn quality job on my cock. I can feel the cum starting to boil up from my balls.

As I watch her I notice something in the reflection of her sunglasses. I can vaguely make out someone walking out of the house behind me. I can't make them out but I know they are walking this way.
