Unexpectedly, my stepfather left a massive load in me after waking me up

I was just turning 18 and had a bit of a naughty side. I'd been sneaking around with my stepdad, getting off on the thrill of it all. He'd been teasing me, making me wait for his big load. One day, he finally gave in and woke me up to feed him my tight hole. I could feel his fingers sliding inside me, stretching me out for his massive cock. He took his time, making sure I was ready for him. Then, he plunged into me, filling me up with his hot cum. It was more than I could handle, but I loved every second of it. His load was huge, filling me up completely. I could feel it oozing out of me, dripping down my ass. It was a sight to behold, and I knew I'd be craving more of his hot load in the future.
