I ducked my mask under to see if she was fouled in something.It was only then that I realized she was naked beneath the waves. I might not have notice... anything but that slender, curvaceous body and the cloud of long black hair trailing behind, had she not been treading water so oddly - using only hands and one leg. I looked closely at the stationary foot and noticed a number of slender black spines sticking out of its sole.Raising my head, I dropped the mouthpiece of my snorkel and asked, "Sea. We sort of sat back on the settee my cock still twitching and her pussy oozing love juice so she slid her hand down between her legs and rubbed it over her clit and stroked herself while she looked at me then over to her man on the other settee who was between my wife's open legs lapping her pussy making her groan and grind her cunt into his mouth,she growled at him to give her his cock to suck so he jumped into the sixty nine position over her and began to thrust his cock into her open. Katherine was incredible friendly and made me feel really relaxed. I told her about my back pain and how I injured myself working. She said "I know exactly what you need, why don't we get started right away". I accepted the invitation and ask if I should take more then my shirt off. Katherine said "You should take all your clothes off, it will make you feel even more relaxed". I instantly started blushing. I'm around 6.5 inches long but no one has seen me naked with the expection of my fiancé. What do you want, Kate? Wha... What can I do? For you?" Well, let me show you."And she kissed him. It wasn't his first kiss. He had managed that, already. One girl had kissed him, once. But this time... Could they actually go further? Here? Right in the bed of a couple he had never met?She said:"Let's try again."And she kissed him again. This time, he kissed her again. And, when he broke the kiss, she said:"Well, a least you know how to kiss. Not bad. You have a nice mouth, do you know that?".
