Nervous Stepdaughter Wants Real World Experience

I have strong feelings for my stepdaughter Aria, and I always make sure to support her. However, today she has tested my limits. Aria is getting ready for her formal dance and confides in me about her concerns regarding satisfying her date sexually.
Despite my initial hesitation, I acknowledge her desire for practical guidance. With her stepmother absent, I couldn't help but notice Aria's attractive, nerdy appearance. I decide to seize the opportunity and engage in a quick, discreet encounter before my wife returns home.
