Stepsister and I got caught in our first sexual encounter

After a long day of classes, I returned to my dorm to find my stepsister lounging on the couch. I've always had a thing for her, and she's been dropping hints that she's down for some fun. So, I decided to make a move. I led her to my room, stripped her down, and started exploring her smooth, hairless body. Her moans grew louder as I delved into her tight, shaved pussy. Just as things were heating up, my roommate walked in, catching us in the act. Unfazed, I continued our show for him, pounding my stepsister's wet, eager pussy. As I brought her to a climax, my roommate joined in, adding his own touch to the mix. The sight of my stepsister covered in our cum was a perfect ending to our first sexual encounter.
