Lonely Xmas night for cuckolds

I had a different humiliati0n from my wife tonight before she and her lover left for a romantic Xmas night in a hotel.
I love playing classical guitar and love to spend time playing it, especially when I'm caged as the hours fly by.
Tonight as knelt by side of the settee holding their dr1nks and chocolate as they kissed and cuddled. My suddenly looked at me and a cruel smile played on her lips, I was instantly both worried and excited. I was surprised when she just said "Get your guitar, play something beautiful and romantic for us."
On my return I set up and was about to play she said "Play beautifully, as I want to seduce him again." My heart dropped as I started playing, the intimacy of them together was electric and I could feel my playing adding to mood. Hearing my wife tell a lover 'I love you' is always humiliating to hear, but it was their gentle kissing, touching and soft words like I wasn't there that drove home the humiliati0n further.
I pored my heart in to my playing and tried not to intrude on their romantic moment.
After about 15 minutes my wife stood up and put out her hand to her lover, saying "I can't for us to be in that hotel bed," and lead him out of the house.
I kept playing til I heard the door lock, I'd been hoping for a backward glance or even a kiss of her heels, maybe a happy Xmas.
So, here I sit caged, humiliated, desperately hoping they have a wonderful night, and I'm feeling so pathetic and horny ❤️😈
