Mysterious Masquerade

Set the stage for a compelling masquerade evening with your partner. Don outfits inspired by masquerade balls, the woman in an elegant gown or dress while the gentleman sports a smart suit. Conceal your identity using masks.
The theme of the night would be to discover the other's identity; use riddles, clues or coded messages for the same. As part of the game, add innuendos and flirty challenges like dancing closely or whispering sultry words.
As the night plays out, let the air of mystery enhance the romantic tension. Once the identities are revealed, let the passionate side take over. This is not only fun but can also allow you to explore different character aspects in a comfortable setting.

Start by creating the masquerade vibes. Clean up and tidy a room in your house, preferably the living room. You can hang curtains or use dim lights to create a ball-like feel on a budget. Use incense or scented candles for a sensual aroma.
Have a playlist ready with classical music, jazz or any tunes that set the romantic mood. Arrange for food and beverages; finger foods and wine can be a great choice.
Choose your costumes. Since your partner appreciates larger endowments, you could consider using a cock ring or penis extensions. A little surprise will indeed add fun to the evening. Don't forget the masks for the mystery element.

Remember, the key to this roleplay scenario is the suspense and mystery. Maintain it throughout the evening. Be a gentleman while she's a lady. Compliment her, dance with her, make her laugh.
Get creative with your identity-revealing game. You could leave hints around the house, or use riddles to intensify the game. Make sure the challenges you incorporate are conjoint and allow physical contact.
Lastly, ensure both of you are comfortable and enjoying the experience. Respect each other’s boundaries and remember the safety word. Relax, unwind, and let the masquerade’s magic do its work.
