One day, when I got home, I found a woman sleeping in my room... It was my sister's friend, Ema! I was happy to see her again after a long time, and it brought back naughty memories... When I realized it, I was playing naughty pranks on her while she was sleeping. Then, when Ema woke up, I was confused and couldn't explain myself... She smiled naughtily and started doing more to me than she did back then...
