Her dress was hiked up over her waistwhich left her pussy with its soft mound of pubic hair open for theworld to see. Not that there was much going on...at this time of the morning.Her hand slid further up until she found the erect clit at the top ofher sister’s slit. Her fingers began to pinch and massage the clit whileLiz worked to spread her legs as far apart as she could. After a fewminutes of gentle work on her clit, Susie said, “Take off your dress.”Susie thought she might balk this time,. “Open your mouth, this dick needs to be pleased, until it cums.” She let go of the base of his dick and grabbed my balls, again driving her nails in as she squeezed. “Open your slut mouth!” I complied to get my balls released. The thick meaty head slid into my mouth, tasting like Tara’s twat. My mouth was a lot bigger than Tara’s and I could fit a good amount in. I did have a gag reflex though. A few tries and he was past it but I was able to suppress throwing up on his amazing cock. He began. I see her looking first at my damp tussled hair, then at the water droplets glistening on my chest and then at the erection hidden by my towel. Despite my best efforts, my hardness is refusing to subside. I smile back sheepishly. Her white tee looks different. No, perhaps not different, it is the same shirt but my eyes are not deceiving me, I can no longer make out the silhouette of her bra underneath and her nipples are straining under the thin fabric. The view is not helping my hard on to. When the elevator stopped at the seventh floor, Seth said aloud, "This is where we get off."They stepped into the hallway and as the doors were closing Liz said loud enough for the other couple to hear, "I'm sure this isn't the only place we'll be getting off tonight!" Let's see...722". Seth gestured to the right and they started down the hallway. About halfway to their room at the other end, Seth said, "Stop here."Liz stopped and looked at Seth. "Hm?" Take off your panties and give them to.
