Sarah is still rubbing my cock up and down when I move one of my hands around to hold her butt and the other down into the smooth and puffy slit that I was admiring earlier. I quickly rub over her pelvic area, to soap up the area, and then start sliding my middle finger back and forth in between her juicy pussy lips. She spreads her legs, just a bit. Each time I slid my finger over her clitoris, I could feel it swelling up.
“ahhhh, that’s nice…” Sarah whispers while breathing deeply and tilting her head back to rinse off her hair at the same time.
After maybe a minute of massaging Sarah’s slit with my finger, I began to slide the tip of the finger into her pussy. With each slip, I would put just a little more of my finger into her very wet pussy.
“uhh” “uhh” “uhh” “Uhh” “Uhh” “UHh” “UHh” “UHH” she gasps as my middle finger went all the way into her tight hole.
She is now just holding my cock tightly, and she moves her other hand and grabs my wrist to keep my finger deep inside of her for a few moments.
Sarah lets out a long breath, and then slowly pulls my finger out of her.
“Okay, bro, now my back.” she says as she squeezes her fist on my cock a few times before releasing it.
Sarah turns around and bends over again to get her conditioner. I take the opportunity to rinse my cock off in the shower spray from her back, and then rub the head up and down Sarah’s crack. Rubbing down across the entrance of her ass and her pussy, I can feel the meaty tenderness of her pussy lips at her warm entrance each time my head rubs across it.
Sarah pours some conditioner into her hand and then stands back upright. I get some more mango body wash and start to lather it up to start working it onto her back. We are closer together now, with Sarah’s chest still under the water while working the conditioner into her hair, and with my dick again snuggled between her warm buttocks, while she slowly rocks her hips from side to side. I again start to rub and massage her shoulders, and I can feel them relaxing under the firm and gentle pressure from my fingers.
Before I finish massaging her shoulders Sarah moves her hands down to her own breasts and starts slowly squeezing and massaging them with the leftover conditioner. I start to move my hands down to her back and Sarah bends forward, to allow easier access to her back, and other things. Her head and back are now in the water, and we both hold our breath for a moment, in anticipation of what’s coming next.
I slowly slide the head of my cock from the top of her round ass, down her crack, and past the dark puckered circle of her anus. I rub the head around, for just a moment, and I can again fell the warm, wet, plushness of my sister’s supple lower-lips. Then I slide my head past her tempting hole until I could feel it pressing against her hood. I rub my head over her clit a few times and then finally ran the head back to her slit, until it stopped, captured in the warm pocket of her pussy opening. Sarah can also feel the warmth of my head and she arches her back down, and pushes her ass out. The tip of my stiff cock enters my sister’s pussy. Her pussy is so tight, for an 18 year old high school senior, but she is so wet, and my cock slides smoothly into her.
