Sissy Dreams: The Promise

My wife loved dressing up in sexy clothes and making role-play part of our lovemaking. But had I gone too far by promising I'd do whatever she wanted after we had a threesome?A few days later I find out, when I come home to find she's invited a friend over to be part of a 'two hot girls and one well-hung guy' threesome. But will I, or the muscular Steve, be the other girl?
