Look at Amber

"Yeah she's really going at it this time, working both her holes. Damn that's hot, just look at that." She says now working her pussy along my cock faster now.

I look up, and out the window to see Amber's ass up in the air, bikini bottom build to the side on her ass. Two fingers pumping in and out of her pussy deep and two finger around the back fingering her asshole.

I stare at this magnificent porn worthy display. I feel my cock throbbing as I push the shaft deeper between Ashley's pussy lips. She moans as I stroke my cock along her pussy.

I watch as Amber starts rocking her hips in time with her fingers. My eyes transfixed on Amber's ass as she works her holes. I feel my balls boiling with cum, I feel Ashley's pussy lips around the bottom of my cock moving up and down the shaft. I know I'm about to blow on my step-sisters ass, as she moans under me.

Then, just like that she drops to her knees and stands up, stepping out from between my legs. I see, suddenly standing in front of me, her body glistening with sweat. Her thin tank top clinging to her wet tits showing her rock hard nipples. I watch her reach between her legs adjust her shorts and then put her wet finger to her lips. She slides it in her mouth and suck on it then pulls it out.

"Hey, your pretty good at this 'helping' with my yoga bro. I think I might use you more, um, for my yoga. Thank you so much for your help, I'm going to go take a shower now." She smiles, bites her lip while looking at my hard throbbing cock and walks past me towards the door.

I look back over my shoulder as she walks across the room, taking her shirt off as she does. I see her small perfect tits from the side in the mirror. As she gets to the door she stops leans against the door frame, arches her back, and pushes her ass out. "It really was fun" and disappears through the door.

I'm stunned, I stand there, with my raging throbbing hard-on. I look out the window and see Amber still pumping away at her holes.
