Nervous Stepdaughter Wants Real World Experience

I love my Step-Daughter Aria so much, I would do anything for her, but today she has really pushed me to the line. Aria is about to go to her formal dance is a bit nervous, she tells me she knows her date is gonna want sex but is afraid she won't be able to please him. I try to give her some advice but Aria wants some real-world experience, usually, I would run the other way in a situation like this but... her StepMom wasn't home and I did think she had a cute nerdy shy girl look to her. I guess I could just do it this one time real quick before my wife gets home.
