"Later" said Sandra "But did you see the anklet Rebecca was wearing?"No" I replied, puzzled.Sandra rolled her eyes and pulling my head down, she whisp...red in my ear."Really!" I blurted out in surprise."Yes, now come on, I need to freshen up."When we got back to the suite there were half a dozen bags laid out on a table, Sandra's shopping delivered straight to the room. She started showing me her selection of underwear sets, negligees and the like when she found a small package."Oh, this is for. " Why don't you?" I said in defiance."Ok, I will but you have to take the other one or else I tell."Heather looked back and forth at us like we were crazy so I took my middle finger, slid it up her slick hole, and rubbed her clit with my thumb. Heather melted, grabbing my head and pulling it to her perky nipple. My sister dove in on the other one. Heather started bucking against my hand in a wanton display of need. I took my thumb off her clit so she could not cum yet but let my finger continue. This is an R-rated movie, right?Just as she turns towards the camera to reveal her full beauty, we hear the door at the back of the theater creak open and see the glow of a flashlight probing down the aisle. Instinctively Jeff and I take our hands off each other's goodies and reach for our tubs of popcorn. Holding our still-warm popcorn over our laps (felt nice on my cock, by the way), our engorged erections won't be visible to the usher, despite our shorts being partway down, even if he shines. I can hear them laughing as they go up the stairs. I refill the boat with gas, put away the floaties and put the cover on the boat. It takes about 25 or 30 minutes before I can head up to join them. As I head in, I figured they were all showered and relaxed, or Lisa and Jeff were going at it and hopefully Betsy was waiting to take care of me.I go in the back door and can hear the shower running, I see Lisa going into guest bedroom. She has a towel wrapped half way around her, showing lots of.
