My stepmother-to-be, who is also my father's company subordinate and just two years older than me, has been entrusted with taking care of me while he goes on a business trip. As part of her bridal training, she agreed to look after me before their wedding. She's incredibly beautiful and has amazing legs. One day, when she was wearing a miniskirt while doing housework, I couldn't resist sneaking some panty shots. Unfortunately, my actions were discovered, leading her to tease and provoke me further. However, despite her attempts to arouse and satisfy me, she always leaves me wanting more.
