On my first family trip with my stepfamily after my parents remarried, I ended up sharing a room with my stepsister at a hot spring inn! My stepsister is beautiful with an amazing figure and has an incredibly perfect ass! As we slept side by side, her yukata slipped open revealing her large breasts and panties, making me extremely excited! Plus, her godly ass was just 3 cm away from my face! I couldn't hold back any longer, so I moved her panties aside and thrust my erect penis into her vagina. I couldn't stop my hips from moving and ended up ejaculating inside her multiple times. Then, my stepsister, who had gotten excited, started demanding my penis, making me continuously ejaculate inside her without stopping！！
