Apriloni1 Giantess - Your Giantess Stepsister's Revenge

As you staggered back to your room after a wild party, you didn't realize you had taken the wrong door and ended up in your quiet stepsister's space. She was the complete opposite of you - a boring nerd who spent her days studying and working part-time at the hospital. The room seemed huge, and it wasn't until morning that you woke up and realized something was terribly wrong. You were now tiny, and your stepsister was a Giantess! Your heart pounded in fear as you heard her heavy footsteps approaching. She was colossal, towering over everything in sight. Desperate for help, you tried to get her attention, but she didn't seem to notice your tiny form. You decided to move closer, but her huge ass almost crushed you. It was clear that you needed a safer plan to contact her. Reaching for your phone, you realized there was no money on it. Then an idea struck: perhaps if you bit her, she would feel it and respond. Taking a deep breath, you approached her carefully and sank your teeth into her thigh. As she screamed in pain and surprise, you hoped she would realize your presence and help you. But little did you know that she had secretly hated you for years, envying your lifestyle and popularity. Now was her chance for revenge - and she wasn't about to let this opportunity slip away.
