Done but not finished

I just sat there, unsure what to say, torn between possibilities, looking at her naked body as she leaned on the desk awaiting a response. When I didn't, Amy turned and began to dress, pulling her plain white panties back up, shrugging into her matching bra, throwing back on her t-shirt and shimmying back into her skirt, her movements efficient and unconcerned with my presence, just getting dressed as if she were alone. She pulled up to her desk, gathered her books and notes, woke up her computer, and began working like I wasn't sitting naked on her bed.

I got up, my mind still reeling, and mechanically threw my own clothes back on, feeling suddenly awkward. Amy didn't spare me a glance, her focus entirely on her homework.

"Thanks for... you know," I said, feeling awkward. "I mean, thanks for letting me use you like that."

"You can use me anytime, bro," she stated offhandedly, not looking away from her work. "But right now, if you don't mind, I really need to get this done," she replied, as if dismissing her annoying brother after he had bugged her for a favor.

I nodded instinctively, not sure what else to do. I paced quietly back and forth in front of her bed, my mind racing, trying to make sense of what had just happened. I mentally kicked myself; if I had thought that website was real, I could have wish for money, health, immortality... no not the last one, that always ended badly... but I could have done better than vaguely wishing about Freeuse.

My mind wandered between the memory of what had just happened and all those videos and stories I had watched, racing through possibilities. I stopped pacing with a start as a thought occurred to me. I had walked into my sister's room, gotten her attention, and she had gone along with anything I asked, treating all of it were normal, and even expecting me to also act that way. That was right out of a freeuse video, but not every video was like that. There were others where things worked very differently. There were videos where things carried on as if nothing were happening at all. Could I do that too? I knew I wouldn't be able to relax until I tested it.

The only people in the house right now were my sister and my mother. Doing anything sexual with my old, out of shape mother didn't hold any appeal. Mother-son stuff was a porn plot I did not foresee living out, not with a mother like mine. So I would need to either experiment more on my sister or go out and find someone else, and I still felt nervous enough to not want to risk that. I looked over and saw Amy's fingers moved quickly across her keyboard as she worked on what appeared to be a pretty long paper, occasionally flipping through various books and papers. That was actually perfect for what I had in mind.

I quietly walked up behind her, reached around the back of her chair and grabbed her clothed boobs through her shirt without saying a word. No tap on the shoulder, no getting her attention, just right to using her. She let out a quick gasp, her body tensing slightly, before continuing her work as if nothing was happening. I massaged her boobs, first gently and then, when she didn't react, more vigorously, my thumbs circling her nipples, which I could feel hardening. She adjusted her posture slightly so I was not in her way, but otherwise just kept working in an entirely unbothered way, reaching a bit to pull things towards her rather than leaning over to look at them, being careful not to displace my hands.

I grinned manically as I confirmed that I could play with her body without her even noticing I was doing it. I grabbed the bottom of her shirt and lifted upwards, her bra-clad tits bouncing slightly as I pulled it over the swell of her breasts. She stopped typing for a second, raising her arms and making it easy for me to pull it over her head, then went right back to work. This was somehow even hotter than fucking her on the bed, and I found myself unconsciously humping the back of her chair. Could I do more? I could clearly play with her body, but could I get her to do things herself without realizing it? Or would talking to her break the spell?

“Take off your bra,” I said quietly, wanting to see how far I could go without her even seeing me. I watched gleefully as stopped typing for just a second, reached back and unclasped her bra, puling it off one arm, then the other before returning to her work, not caring she was topless and still not acknowledging my presence. “Play with your tits,” I said, no longer whispering. She simply took one hand away from the keyboard and squeezed a breast while the other continued working, albeit much more slowly. A few soft moans were the only sign that she feeling what she was doing to herself. She alternated between her tits, squeezing and kneading them, swapping hands so she could grab notes, typing one handed. Her face has a frustrated look on it, a slight furrow of her brow, as her progress slowed down, but she didn’t seem to even consider using both hands. I felt a little bad about that, and also curious what would happen, so I pulled her fondling hand away from her chest; as soon as I let go, she went back to working with both hands without missing a beat.

“I want to see you Cum,” I said, wondering what would happen. I expected her to stop working and play with herself, but instead her breathing hitched, her hips starting to grind against the chair. A low moan escaped her lips. Her back arched, head shooting back, as she underwent a full body spasm, her hips humping the air, skirt swishing across her thigh, boobs jiggling. She cried out, the sound of it nearly making me cum in my pants, but then she relaxed, her breath coming in short gasps, and she settled back into her seat like nothing had happened. She had gone from nothing to full body orgasm and back again just because I told her to, without even typing a single wrong letter. The only sign that anything had happened was the way she was breathing a little harder than before.

Her complete lack of reaction, her ability to keep working even as I used her body for my own pleasure, was intoxicating. I pushed some paper out of the way and leaned against her deck, finally looking at her half naked body as she carried on obliviously, grabbing one of her hands and resting it to my clothed dick. She didn't resist or pull back, but instead began sensually running her hand up and down my clothed bulge, continuing to work one handed again. I grabbed her bare breasts, feeling their weight and warmth and squeezed them roughly, bouncing them up and down, pinching her nipples, as she kept palming my clothed package and now reacting at all. I saw her look in y direction with a confused look, and thought for a second she was finally noticing me, then realized she was looking for the papers that were now behind me. I picked that pile up and moved it over to the other side, and she shook her head, as if chastising herself for losing track of them, and started rifling through them one handed, as if they had been there the whole time.
