I caught my stepsister masturbating but she asked me to stay

Movie night with my stepbro 🥵 POV: the party is over and everyone went to bed...you come in my room to see if I want to hang out since we have to share a bed anyways BUT you catch me masturbating. You play it off. We turn on a movie. I'm obviously very sexually frustrated now and still super horny, so I start to reach for your cock under the blanket. It's HARD 😱 You promise it will be just our little secret. No one will know 🤫 ! all POV!! cum in mouth/on mouth
