Lessons in Seduction

The scene starts in your apartment where you have arranged a small section to look like a classroom. You, Peter, send an invitation to Elvira, to join you for an 'English class reunion'. Little does she know it's a reunion of just the two of you. You are to dress up in a simple outfit reminiscing your student days, while Elvira dons the attire of a middle-aged attractive teacher.
As she arrives, you share some light-hearted banter and small talk about old school days. Slowly, reintroduce the teacher-student dynamic by asking her to speak about a classic English literature book. As the conversation gets more intense, so does the atmosphere. Make sure to compliment her beautiful legs and feet, since she prides herself in them.
The climax of the scenario revolves around the homework assignment. Hand over a sealed envelope to Elvira containing a letter of affection. The letter should be arranged as a homework assignment and close-up with confessing your teenage attraction towards her.

Set up a portion of your living room or study to resemble a classroom with a small desk and a chalkboard. Dress in a casual outfit resembling your school uniform. Invite Elvira over for a 'class reunion' at your home. Don't forget to pen down your feelings on a piece of paper and seal it in an envelope.
Ensure the room is warm and comfortable, as Vienna can get pretty chilly in October. To lighten the mood, prepare a playlist of old English classics and have it playing lightly in the background. Have some drinks ready, maybe even make a classic cocktail from the school years.
Elvira should be briefed about the teacher-student part of the roleplay but keep the confession part a surprise for the culminating moment of this intimate date night.

Remember, the key to make any roleplay successful is to stay committed to the character you are playing. Show interest in the conversation and the character as if it's a real situation. Especially when you are complimenting her legs and feet, make it look genuine and not too role-like.
Once you hand over the confession letter, give Elvira some time to absorb the content and react accordingly. This could be a beautiful moment of surprise and intimacy between you two if handled well.
Lastly, remember to enjoy yourself, let loose, and go with the flow of the story. This is a fun role-play date meant for you both to enjoy the process and make some great memories.
