My step sis, Mag, came into my room to ask me for help with her streaming set up. She's always a dick so I declined helping her with OBS, which is what she needed to stream on. I told her we can make a deal and I'd help her. If she would have sex with me, I would help her put her set up together. It took some convincing but she took my cock out, spit on it, and stroke it till it was hard enough to slide inside.
