Well their funtime ended when a cat ran into the yard and the dog went nuts barking, they dove into the water and hid from sight. I took that time to ...uickly go inside and up to my room. I fingerfucked myself until I passed out.Many nights had passed and I had braved up the courage to make a move on my sister. we were skinny dipping as normal. I would swim close to her, rubbing my tits (which where a cupsize bigger than hers) on her back and then we playfully groped eachother. I had managed to. My cock was throbbing in my jeans so i eventually gave in and went down on her she was moaning with pleasure though i tried to hold her mouth so not to wake my partner she just couldnt stop i got her over the couch lifted her skirt and ripped of her panties and sunk my throbbing cock deep inside her and started to fuck her tight wet pussy my partner shot up n shouted what the fuck i tried to pull away nothing else i could do or say but to my suprise my partner walked over and started to kiss me. She looked down at me thoughtfully before giving me a hug, "Then youbetter make it out of this safely." She let go and said, "Alright, areyou ready for a few more toys and some training?"I nodded and held my arms out to her, "Up?"She laughed, picked me up, and then proceeded to take me to a room marked'combat simulators.' "Have you been in the simulators at Whateley yet?"Dr. Thunder asked as she sat me down on the ground next to a disc shapedplatform with a rail around it."Umm... I've heard. “Why do you think?” I asked, grabbing her hip and trying to get some leverage so I could fuck her again.“I don’t know,” she replied, pushing against me harder, “I told you, I’ve only been with four other guys. I’m not a slut.”“Darlin’, being a slut isn’t always about how many men you’ve been with. You came into my cell and immediately started undressing,” I told her, “then you let a guy who doesn’t even know your first name shoot his load inside your cunt, not once, but twice, now you’re asking.
