I was so excited. I began to walk inside to say hi to her and as I reached out to say hello, it hit me. She was my neighbor that lived a couple blocks...behind me. “Do I know you?” she asked as I approached.“I'm your date.” I said quickly. She smiled. “You look familiar. Have we fucked before?” “No.” I didn't know what else to say.“OK. Well follow me.” she told me and I got into my car and followed. Pulling up to her house, something else hit me, she was married.“Are you married?” I asked her. “Okay, what do you think?” said Erica.“Perfect, let’s see what you’ve got.” I said.Erica sat down in the center cushion of the couch to get herself in a good position. She began extending all of her appendages outwards about 5-6 feet and let them go limp for good measure, really driving home the feeling of “the ultimate relaxation”. In the meantime, Erica’s torso was now yards longer than it normally was, fulfilling the requester’s description nearly perfectly; soft and stretchy body, strewn. The scientists taught her how to read and write and become just like all the other humans. They eventually decided to release her into a high school to give her social interaction. Subject 19 saw her chance of escape.During class she noticed a girl that looked exactly like her, this intrigued her, who was this impostor? Instead of running away, like she planned, after school she followed her home. I was on my way to Susan's house for some "study time" as we told our parents, her parents would. Her wetness was making the whole area slippery. I decided to take advantage of that and started to rub her perineum area, also known as the taint. I whispered in her ear "I want to fuck you." She agreed and rolled onto her back. I said, “No, I want to fuck you from behind so I can see your pretty ass."Kim and I usually make love in the missionary position of some variation of that. Tonight I didn't want to make love, I wanted to fuck. She must have felt the same way because she didn’t argue at.
