My stepsister discovers me pleasuring myself with her underwear and has passionate sex with me, resulting in her receiving my ejaculation in her anus

I was chilling in the living room, scrolling through my social media feeds when my stepsister came in, looking all hot and bothered. She had just come back from a long day at work and was feeling pretty frisky. I didn't mind, I've always been down to play along with whatever she wants. So, when she caught me pleasuring myself with her underwear, I didn't even bat an eyelash. In fact, it only made things more exciting. After a quick chat, we got down to business, and as we started to get into it, she let me take it up the ass. It was a wild ride, and when I finally came, she took it like a champ, even squirting a little bit. It was a crazy, taboo-filled encounter that left us both pretty satisfied.
