GS-245 - My stepmom is too hot... Dangerous life with a stepmom my age

My dad brought home a young, hot stepmom who's basically my age. As a shut-in, I'm losing my mind because she keeps teasing me on purpose. She parades around in lingerie, and when she sees me getting hard, she just laughs and takes it into her mouth. She's turning me into her sex toy right in the living room.
