She ran to the en suite bathroom and brought a glass back to the bed and began to collect as much of the cum as she could.“what are you doing love?�...� asked her dad“just collecting the cum. I love the taste and I can drink it later.”“oh this is all too much, your only 13 and you’re drinking cum with breakfast and you wank like a pro that was fantastic.”All the bedding along with Petra’s lovely pyjamas had to go in the wash and at breakfast nothing was said about what had happened. Petra slept. My brother and I walked for a while and then went back to our parents. We packed up our things and headed back to the boat. As we walked through the section of beach where no one was naked, I turned to Mom."Why do you see the couples here kissing and stuff and you don't see it on the nude beach, Mom?" I guess that if two people kiss when they're naked, it's considered sex." That's silly, isn't it?" Yes, Jen, it's very silly."We got back to the boat and decided that we needed to get ready to go. I checked, rechecked, double rechecked and still there was nothing there. I sat staring at my equipment debating between suicide and just disappearing forever when a soft voice said, “David, we need to talk.” I knew I was alone in the lab and was so startled that I yelled out, “Who’s there?” before I realized that the voice was coming out of my data console speakers.“I am Deep Interstellar Probe ServoMech E-13. Humans usually call me Dipsy or Dipsy 13 or just 13. I don’t know how you. If it pleased you, I would be your obedient little slut.That evening, freshly showered, shaved and plugged, I waited for you to get home. When you did, you smiled at my eagerness, noting the large wet patches where my milk had leaked since I last pumped. You slipped two fingers into my cunt, noting that it, too, was dripping. Arousal spiked through me; I could feel the milk leaking out and soaking into the thin fabric of my dress. I swallowed hard as you told me to undress and wait on all fours.
