I step out of their shower and wrap a towel around myself. I walk into their bedroom and they are on the bed. I can see his erection through the thin ...material of his shorts. They are kissing and he has opened the zip on her hoodie. She has no bra on and her breasts are exposed. She is dimpled with gooseflesh and her nipples are hard. They stop as I enter the room and look at me. I am nervous and frightened. He stands and walks towards me. He kisses me and it is surprisingly gently, like he can. I reached down and touched her wet lips, took my penis and entered the head inside her pussy lips, reached under her to cup her beautiful breasts; her nipples hard as diamonds in my palms. Ever so slowly, I entered her and felt my cock entered my sisters tight, little cunt. In all the way, then I withdrew slowly and rammed in fast and hard and she screamed "yes" and I smiled. In and out using her and taking her, she was crying with joy and mumbling "yes Master take your whore, this is so. I parked the rental and went inside to leave the keys at the desk and the girls headed towards the bungalow. Rafaelo handed me a note and said it was for us. I asked him what it said and he claimed he didn’t know as it was sealed. I opened the note, read the note, smiled and headed to the bungalow to share it with girls. When arrived, the girls were changing into their bikinis as they thought a relaxing swim sounded good. I handed Pepper the note and went to put my swim suit on. She looked. I couldn’t understand why Mrs Walden had one and why she had left it on the bedside table in full view. Was it deliberate? It got to lunchtime and my day’s chores were almost done. I made myself a sandwich as I always knew mum would make a large dinner. I sat in the lounge with a coffee. Goldie staring at me still and that fake cock in the bedroom had my head in a spin. Finally it was too much. Cleaning up I headed for the bedroom. I had to know what it felt like to have something pushed into.
