Shameless Mom and sister

I wadded ashore just moments behind my mother and sister who reached back to take me by the hand and rush me to the beach blanket that I had spread out under the umbrella. "Come on honey, your sluts want to show you just how much we want to fuck you in public."

"What's with the mini-cam?" I said as I lay down on the blanket.

"Mom thought it would be kind of fun to video our fucking is that okay with you?" Kate said as she made sure there was more than enough tape.

Paula did not want to wait, she tugged on my bathing suit and pulled it from my hips exposing my erection. "I am sorry my love but mommy's mouth needs your cock right now." She said. I though for sure that I was going to cum right then and there but my mother knew how to keep me from cumming.

"Oh fuck mom you look so good sucking Kevin's cock." Kate said sounding excited. "And what a beautiful ass you have mom, move it around a bit."

I don't know if anyone was actually watching my mother sucking on my cock while being filmed by my sister and I didn't care. I knew that there were other people on the beach but I was guessing that they were in their own world.

"Come on Paula ride Kevin's cock, I want to see the look on your face as he fucks your pussy." Kate said urging our mother to stop sucking my cock and to ride it. "Let's see the slut that you are mom."

Paula stopped sucking my cock and looked at the camera a fake pout on her lips almost made me laugh. "I am Kevin's slut and proud of it Kate, I was not going to let him cum in my mouth this time, I was saving that for later." Her false pout turned into a real smile. "And I am glad that you like mid ass honey because I sure like yours."

Paula mounted my cock and happily rode it as hard as she could. "Oh Kevin my love, promise me that when we get home you will take me to the dungeon for some special fucking."

I said that I would do so even though it came out more like loud grunts and moans and I knew that I was getting real close to climaxing. "Next time," Paula said gasping loudly. "Your sister will have to remember the tripod because all three of us should be on camera."

That was it for me, I started cumming filling my mother's vagina and I could just make out my sister urging me to keeping pumping my cock into our mother. "Yeah Kevin, look at our lovely slut of a mother go! She's having another orgasm!"

Paula rolled off of me and lay with one of her arms across my chest. "Fuck that was so damn good." She then rolled against me so that she could kiss me on the mouth. "Your father never made me cum the way you do my love and Master. I swear that I can still feel your cum pumping inside of me."

"You mean that you wouldn't go back to dad if you were given the chance to do so?" I said.

"Never, you taught me who and what I really am, I am a cum bucket, a submissive slut who no matter what the conventions of society have to say is in love with her son." She looked over to where Kate was kneeling. "I am also in love with Kate who is my daughter and dare I say it co-slut and lover."

Kate crawled to where our mother was and she bent down to kiss her on the lips. "I love you too mom, I am sorry for all the trouble I caused you."

"That is all behind us now honey, we are new women now, Kevin is our Master and I believe that it is now my turn to film you fucking Kevin. I love watching you two fuck, it looks so natural and good."

Kate bit the top of her lip as she started to cum and this set me off as I thrust my hips off of the blanket trying to bury my cock as deep into my sister's vagina as I could. "Don't stop cumming Kevin, keep pushing your cock inside my pussy. Ah! Ah! Yes! Master that feels so wonderful!"

Paula, Kate and I rested on the blanket drinking water that we had brought in the cooler. "I once dreamed of having sex in public." Paula said as she brushed the sand from her breasts and her belly. "I never thought it would really happen."

"And now that it did what do you think?" Kate said as she too brushed herself down. "I thought it was thrilling just the thought that we might get caught excited me."

"Me too honey, I can't wait for the next part of our date to happen." Paula said as she took her daughter my sister by the hand and ran into the water to wash themselves off. The next part would be on our boat.
