Tammy was looking pretty hot in her summer dress, and I couldn't help looking her way as often as I did. Kay jumped up and said she needs to dive in a cool off, then jumped in the pool and started swimming a lap. Carl got excited seeing this and moved to the edge of the lounge so that he could get a better look at the pool, and Kay.
Tammy jumped up and said she needs to cool off as well and dived in still in her summer dress and no underwear. She followed Kay down and back and then walked out the steps with her dress hugging her wet body and showing off her lovely curves. Kay stared and exclaimed, "you don't have any underwear on!" Tammy quickly stripped the dress of over her head and said "that's right sweetheart. I never wear underwear if I can help it", now standing on the top step completely naked! Kay's mouth was open so wide in amazement I think she could have fit an apple in and chewed the core! Carl stood up and moved to the side of the pool and said to Kay, "Tammy and I never wear underwear or swimmers if we can help it!" To this he dropped his shorts and T shirt and dived in fully naked, to Kays wide eyes and amazement!
Carol said to Kay "you better get out now and perhaps get ready to go home!" Kay told her grandma she didn't want to go home yet as it is still too hot, and she wants to swim some more. She turned around and dived under the water and swam down towards the deep end coming up and holding the edge at the other end. Carl climbed out the steps and gave Tammy a playful slap on her bare arse and kissed her as he walked around to dive in once again. I could see that Kay could not keep her eyes off his large cock.
Tammy turned to Carol and said come in its great. Carol who only had a slip on and a loose blouse stood and removed these and dived in too Kays's exclamation of "GRANDMA!!!"
Since I was the only one, besides Kay still dressed I got up and dived in as well. When I surfaced i slipped my clothes off and threw them on to the step where Kay was standing. She was very surprised. She asked her grandma if she could do the same thing? Carl and I looked at each other and smiled!
Carol was hesitant at the request but said if she really wants to then it would be ok.
With that Kay ripped off her top and climbed out of her bottoms and dived in passing close by me and Carl. Both of us followed her underwater and watch as she surfaced at the deep end. Both of us exclaimed how hot that sight was!
Tammy swam over to me and grabbed my cock and whispered in my ear, "would you like to do something with Carols Granddaughter?" My cock twitched in her hand, and I replied sure I would! Tammy held my cock hard and dragged me to the steps, then climbed out with my cock still in her hand and went over to the seats and pushed me down so that I was sitting facing the pool with a hard on that was pumping big. She immediately engulfed my cock with her mouth taking all of it down her throat at once. While she was doing this she was looking to see if Kay had seen what she was doing. Kay was at the steps watching everything.
Tammy worked up and down my shaft mixing saliva and water and making loud slurping noises as she sucked my bone hard. My head was back on the cushion and my hands were working her head up and down making sure she was getting all of my cock in. Carol, also now on the step next to Kay asked her if she had ever seen anything like that before? Kay said no she hadn't but had heard the same noises from her mum's bedroom at night! Carol told Kay to get closer to get a better idea of what was happening. Kay moved over next to Tammy and watch intently.
As Kay was watching Tammy and I, Carl sat down in the other chair and Carol started taking his massive cock in her mouth and tried to swallow as much as she could. Kay was now trying to watch both women at the same time. She looked amazed at her Grand mum going up and down on Carls 9 inches.
Tammy was sucking me so well and I had been hard and Horney so long it didn't take me long to empty my load in Tammy's mouth! She took the load, but some did seep out the sides of her mouth which she licked up nicely. Kay was amazed at the way Tammy cleaned me up.
As Tammy was finishing me off i could hear Carl working up a big load. Carol soon had him cumming so much that she couldn't keep it in, plus she doesn't like to swallow anyway so as she took her mouth off his knob cum flew everywhere. Kay was close and got some on her tits, to her surprise. Most went over Carols face and tits. Tammy moved over and started cleaning Carol up by licking Carls cum off her body. Kay wiped the cum from her tits with her fingers and tasted it. She said it was salty but nice. Tammy said she should help her clean her grand mum up. Kay moved over and started licking cum from her grandmothers' tits and was in sheer joy doing it.
After everyone was cleaned and calmed down we sat around discussing the events that just happened. The most important point was that Kay does not tell her mum or anyone else what has happened.
