Suddenly, she leaped up from my lap and headed toward her bedroom. My pants are wet from outside, Im going to change real quick. Dont move! she insis...ed as she rounded the corner. I sat there, a little surprised yet relieved that she had gotten up. But that was soon to change. She came back wearing think sleeping pants and a tank top that was a little too revealing to be worn without arousing every man in site. Great I thought to myself. Is she TRYING to tease me?? I change into something. Me and my brother luckily got our own room so that was nice. While they were taking care of that boring stuff, I was getting pretty sweaty from tanning and decided to take a dip in the ocean. As I slowly walked in the water felt so nice against my feet, it was so warm. It was incredible how shallow it was so far out. I was probably a good fifty yards out off the shore and the water was only up to my belly button, but the waves were pretty powerful. I was just standing there taking in the warm. We made it back home just shortly after 8pm. Amanda said she was going to go upstairs with Jade, get her stuff in the room, and wanted to know what we'd be doing. I just said we can chill, watch movies, hang out in the living room or whatever."Cool. Back soon." and off they went.As they were going upstairs, I could not help but look at Jade and my step daughter's asses. I'd gotten so horny and out of hand with the way my step daughter looked even in something simple like shorts and a t-shirt,. She just engulfed her whole mouth around it. Her lips were in my pubic hair in no time. Mrs. Summers was talented. She formed a perfect O with her lips and started bobbing her head violently. My cock had no choice but to respond. I was rock hard in no time. She backed away and nodded her head with satisfaction."Ok doctor, now what?" You better get on all fours, Mrs. Summers." Yes Doctor," she said with a happy smile.I slammed my cock into her ass. It was a little smoother inside than her.
