Is it embarrassing to fuck my stepsister right before my mom’s eyes?

It was another boring day. My stepsis and I sat at a family dinner and discussed curricula with our mother. We were bored when suddenly a great idea occurred to me. I whispered to my stepsister’s ear that I want a blowjob, here and now! She motioned her finger at her temple, but I pushed her under the table. While mom was teaching us morals, my stepsis sucked my cock nicely! Stepsis liked it so much that she dragged me into another room and fucked while my mother started cleaning the house, and was walking just a few meters from us. It was extreme! Can you guess if she caught us, choosing very bad timing for entering my room, while stepsis was giving me a blowjob under the blankets?
