After another hour of snooping through her phone while edging myself, her phone died. I could keep stroking, maybe even to completion. My hand moves up and down my length as I remember what she looked like in her bed. If she were in bed with me now, like she will be in the future, I wouldn’t be able to hold myself back. My hand worked itself a little harder, imagining what she must feel like. I didn’t know which I was most looking forward to: her mouth or her cunt. My hips rose and fell in tandem with my hand, as I pictured sliding myself into one orifice and then the other. My cock leaked more precum onto my hand, making it move more easily along the throbbing length.
I wondered how many times I could just do this, touch myself, to her, in front of her, without her realizing. The thought made me harder. I hadn’t ever had thoughts like these until Mona. It was like she awoke the most perverted parts of me, and the only person I want to benefit from them, other than myself, is her. Plans began to formulate in my head to alter, only slightly, the ones I had already been making. I pictured stroking myself, just as I am now, right over her as she does her extra credit.
Fuck. Why am I doing this myself when she was right in there? Yet, my hand moves with more determination as soon as I think about her proximity to me. I wondered if maybe I didn’t push her hard enough rather than too hard. Maybe, if I’d pushed a little harder, I’d be fucking her instead of my hand. My hips thrust up as I imagine thrusting into her as she rides my dick. I can almost hear what she would sound like just from the noises she made at dinner tonight. Only from a deeper place, and without holding back. I closed my eyes as I jerked myself off to images that will hopefully become reality soon.
I almost stopped when I heard her footsteps in the hall. I hadn’t closed either of our doors all the way, but I had expected her to still be out of it. Still, she wasn’t saying anything. I kept my eyes closed even though I could hear the squeak of my door as it opened slightly further. I could feel her watching me. I kept my eyes closed and tried to suppress a smirk as I slowed my hand. Knowing I had an audience, and who it was, brought me right to the edge. That’s right, baby. Watch me cum for you. No sooner had I thought it, then I was shooting onto my hand and stomach with a moaning, “Mona,” I allowed to escape my lips. I grunted over her quiet gasp that I pretended to not hear. A few more pleasure-filled curses hissed out as I milked every drop I could for her to see. Just to ensure the seed was fully planted, I moaned out, “Fuck, Mona, I love you.”
I casually stroked myself as I lay in the blissful aftermath of my orgasm. I listened intently for my niece, hoping that last line would sit with her. After a few minutes, I heard her walk back into her room and close the door. Satisfied with how that turned out, I cleaned myself up and went to bed much more hopeful about how tomorrow would go.
