I stood at the window, completely nude, watching the scene before me. It was like nothing I had ever seen before, and I was shocked at how aroused I was becoming just by watching. I felt a moist heat gathering in my own aching pussy. I knew I should look away, but I just couldn't tear my eyes away.
The girl whose pussy was being eaten out was thrusting her hips meeting the probing tongue and fingers of the other girl. She was moaning wildly. Only Derek's strong fingers kneading her breasts seemed to hold her down. The girl bucked wildly as the intensity built. Her moans turned to shouts, "Oh my God. I'm coming. I'm coming...." Seeing her writhing around as her orgasm took hold had my pussy throbbing. The girl finally seemed to calm down her wild wiggling and Derek let go of her.
I was surprised at how disappointed I was that it was all over. It was the sexiest thing I had ever seen. I was about to sneak back to the shower when I realized how naive I truly was. The sex was apparently far from over. The girl slid off the lounge chair revealing Derek's huge erect cock to my eyes. The other Barbie sat on Derek's lap, facing outward, lowering herself slowly over Derek's cock. She soon worked up a nice rhythm sliding up and down his cock, her breasts bouncing up and down. Her legs were wide open straddling the chair. I could see the cock slipping in and out of her pussy while she fingered her clit. The second woman busied herself with adding her fingers to the girl's clit and juggling her bouncing tits.
As the girl's moans grew louder, I felt my own need rising. My pussy ached to be touched. Without thinking, I reached for my breast and gently pinched my hardened nipple. The pleasure was immediate. A shock of sensation flashed through my nipple and immediately settled deep in my core. I watched the girl's pussy getting impaled from below as my fingers trailed down my stomach and lower still toward my own yearning flesh. I gently swiped my clit with my finger and felt an electric jolt in response. My fingers rubbed deeper into my folds, seeking to relieve the burning need.
I was just starting to dip a finger into my wet slippery hole when Barbie had an orgasm. I watched as Derek pushed her off of him and got up from the lounge. He still had a full impressive erection. He said something to the girls that I could not quite hear and then gave one of them a stinging slap on the ass. I could see the red hand print forming on her ass cheek. The girl bent over in front of him, volunteering her ass for more. I heard Derek laugh as he slid two fingers inside the bent over girl. She wiggled her ass as Derek pumped his fingers in and out of her.
I was so turned on watching the scene that I slid my own fingers deep inside my pussy and began working myself as Derek worked the girl. After a few minutes, Derek slapped the girl's ass again and withdrew his fingers. The girl joined the other Barbie on the lounge, but she climbed up onto the girl and sat on her face. She lay down on top of the girl, putting her own head between the other girl's legs. They began working each other's pussies. Like Derek, I watched the girls 69'ing each other. I could see one girl very well, licking pussy folds, flicking her tongue over the other girl's clitoris, and alternating her fingers and tongue to probe the girl's vagina.
My pussy was a hot and sticky throbbing mess. I felt the intensity building deep within and knew I would climax soon. I slid my wet fingers out of my pussy and stroked up and down my swollen clit. Derek moved above the girl who was on top and started pounding his cock into her. I couldn't tell if he was fucking her ass or her pussy from this angle. My fingers worked frantically, stroking my sweet spots as I watched the three writhing bodies only a short distance from me.
I felt my climax about to explode. A few hard swipes of my fingers across my clit then slipping to thrust into my quivering pussy was all it took. My muscles clenched as tremors shook my body over and over. I felt my warm juices burst and drip down my fingers and thighs. I removed my fingers from between my shaky legs and continued to watch as my body gently quaked with the after shocks.
Derek suddenly pulled out and slapped the girl in the ass again. Both girls immediately sat up. Derek stuffed his cock into one girl's mouth and rammed it down her throat. I saw his perfectly sculpted ass clench as his body stiffened. He shot his load into Barbie's mouth while she hungrily gulped it down. The other Barbie pushed her away and greedily sucked at Derek's spewing cock. I watched as she licked it clean.
I stood dazed for a few moments. I was still feeling the after affects of my own powerful orgasm. The two naked women giggled at something Derek said and then jumped into the pool together. I looked about the cabana. I still had no way to escape. I was about to slink back to the relative safety of the shower, when the cabana door slammed open.
