As the Birthday party wound down and the sun dipped below the tree line, the bartender and DJ began packing up their equipment. Fatima was using Mom's kitchen to prepare an evening meal of baked ham and mac n' cheese. Mom was helping her. Dad and Aunt Mary had disappeared again. The twins and the other girls, still in their bikinis, retreated to the family room to play video games. Jaz had mostly sobered up and joined the others in the family room. She apparently didn't remember anything of her earlier exhibition.
I grabbed a couple sodas from the refrigerator as Jaz staggered into the kitchen to ask Mom if she could stay over tonight. I could understand that she had no interest in going home to her mama in the condition she was in. Mom pulled Jaz's bikini top back in place to cover her exposed right nipple and then told her that she had already called her mama for permission. I could see the relief in Jaz's face.
Fatima took advantage of Mom's distraction and ran her hand up the leg of my bathing suit and cupped my balls. She sent me an air-kiss and released me but the damage was done and my cock started its steady rise in spite of my efforts to squelch it. I hurried out of the house to the yard before anyone noticed my condition. I handed a soda to Sylvia and with my body blocking the view of everyone else inside, Sylvia picked up where Fatima had left off.
Her nipples hardened and pushed on the shimmering material of her bikini top. They were very close to being exposed by the swooping neckline. Her face flushed and her breasts swelled from the increased blood flow. She was already heaving in air and her nipples broke free. She tried unsuccessfully to pull her top up to cover them. There was just too much boob stuffed in there already. She looked up at me and her eyes were on fire. She gripped my hard cock and said, "I'm so horny. Is there someplace we can go?"
With the sun no longer boring in on us, the temperature had cooled. I nodded toward the hot tub. She turned her head to look and then released my cock and headed that way. I followed and glanced back at the house to see if anyone was paying too much attention to us. No one was, except for Fatima, who grinned and gave me the jerk-off signal with her hand. I signaled her back by flicking my tongue rapidly up and down like the forked tongue of a snake sniffing the air.
As we settled down in the swirling water of the hot tub, Sylvia positioned herself in front of me and tugged on my bathing suit. I lifted my ass and she pulled my suit to my thighs as my cock surged out splashing water in her face. She pulled her face back and spit out water. She grinned as she looked down at my cock, visible just below the surface. She was submerged to her neck but her motion indicated that she was tugging her bikini bottom from between her legs and her eyes closed as she moaned. She was obviously fingering herself. I watched the various contortions of her face as she diddled herself with her left hand and stroked my raging hard cock with the right.
She looked around the hot tub and pulled my cock to the right to guide me into a deeper sitting seat. Where I was sitting, she would have been fully exposed if she pulled herself up and on my cock. In the new position, she would be shielded by the water, especially if the jets were on, which she then reached over and turned on.
She wasted no time as she pulled herself to me and positioned herself in my lap. She didn't face me or position herself facing away either. She was sideways and she turned her head slightly and kissed me passionately. I held her with my left arm with her feet positioned outside my right hip. With her hand guiding my cock, she fine tuned her position and slowly slid herself onto my cock. She moved slowly, aware that the water would wash away her lubrication, but she was so horny that she slid all the way to my balls without discomfort. She turned her upper body to face me and put her hand gently to my face and kissed me again. She flexed her pussy on my cock and I returned the favor. She grinned at me and flexed again. I did the same and she groaned. Her hand went to her sex and I could feel her fingers stroking through my pubic hair and her sex. Neither of us were giving any physical indication that we were fucking as neither of us moved. To anyone watching us, Sylvia was just sitting in my lap as the jets splashed water around us.
We may not have actually been fucking but my climax began swirling around in my groin. The additional hardness signaled Sylvia and she muttered, "Oh my gawwdd, Dex. I'm so hot. I'm almost there. Wait for me." She flexed her vaginal muscles hard on my cock. I gritted my teeth to hold back and to flex my cock as hard as I could. Fuck, I was close and I thought my head would explode trying to wait for her. We were in a passionate kiss preparing for our joint explosive orgasms when there was a different kind of splashing. I broke our embrace to see what it was.
As hard as my heart was hammering in my chest already, it leaped up into my throat when I saw Dad and Aunt Mary settling down in the hot water beside us. Aunt Mary had her bathing suit on. Dad had settled down into the water before I opened my eyes. I could only surmise that he had his bathing suit on too. I couldn't imagine him otherwise with Sylvia sitting here in my lap. They didn't seem to realize what we were doing or else they didn't care.
Sylvia was so close to her orgasm that she didn't immediately register the rise in water level from two more bodies. I nudged her with my arm around her back and she opened her eyes and they went wide when she saw Dad and Aunt Mary sitting there beside us with bubbling water surging around their necks. Their eyes were closed as they luxuriated in the hot water.
My pending orgasm disappeared almost instantly and I started to lift her off my cock as inconspicuously as possible. Sylvia resisted and mouthed the word, 'no'. I let her settle back down on my cock and she stared at Dad's and Aunt Mary's closed eyes as she flexed her vaginal muscles again. I mouthed the words, 'Are you crazy?' She just grinned at me and flexed again. I flexed too and it wasn't long before she was back up again. I was nowhere close.
As her orgasm eased into her, she pushed her face into the crook of my neck and shoulder and buried her groans there. The roar of the jets prevented even me from hearing her. Her body writhed in my arms as her pussy clenched hard and then released on my cock. It repeated several times. The waves caused by her lurching body were lost in the water bursting to the surface.
The jets were on a timer and they could shut off any moment. When Sylvia's orgasm subsided, she kissed me on the chin. I was concentrating on Dad and Aunt Mary sitting beside us. I slowly lifted her off my granite hard cock and she pulled the material between her legs back in place. While she was still lifted off me, I lifted my ass and pulled my suit back up. It was a struggle getting a wet bathing suit on over my erection, but I finally got it.
