Everyone always sends gifts to theor dommes and mistresses, but you like being special and different. You want something personalized to make her happy, and she loves that you want to do such a thing. For her, she wants you starting a chastity regimen, locking yourself up for the holiday season. A little bow and sign around the cage you'll be wearing that says "do not open until christmas". It'll be a festive and fun gift for her to unwrap on christmas and seeing the explosive orgasm you've earned for her. She puts you in the desired cage., locking you up tight. Now, of course chastity is fine but challenging yourself is what impresses her most. Watching her lithe body, you ache in your cage already as she visually stimulates you. Her joy expands as your cock in your cage expands for her. She doesn't want to set you up to fail, so she isn't too mean, but certainly enough to bring her pleasure and joy from watching the dripping swollen mess that is your cock for the next 25 days. Happy Holidays to Your Mistress!
