I pranked my step sister to rub my dick without her realizing it. I then cum and showed it to her.
On April fools day she decided to prank me by texting my girlfriend saying that I was sick. She then got on my bed and covered her face under the blanket and just had her ass and pussy out. I walked into my room and thought that it was my girlfriend and started fucking her. A couple of minutes later my sister shouts “April fools” and shows her face. I was shocked that I had just fucked my sister. She laughed and started touching my dick and then sucked it. She asked me to fuck her again and since I had already started, I thought why not. I fucked her hard in several positions and when I was about to cum, my stepsister was on top and she wouldn’t move as she wanted me to cum inside her.
