A beach day with your family isn t exactly the ideal way to celebrate Labor Day. When my step dad and my step-sister Serena hit the sand, it gets boring fast. I tell my step-sister I m going to lose it & she starts sneakily teasing me with her big natural tits behind our step dad s back! Serena seizes on step dad s suggestion to take a walk & drags me to a private area of the beach. She has my dick out & in her mouth in no time, as soon as I m hard she asks me to fuck her! Serena hops on top & her big tits start to flop as she rides my cock. I bend her over a picnic table & slam her hairy hole from behind. We go for one more round & I make her orgasm, then she drains the nut out of me. Just as we finish up, we hear step dad looking for us and have to scramble.., Labor Day just got a whole lot more exciting folks!
