Let's Be Strangers

I'm in a committed relationship with someone I trust very much, but sometimes the thrill of the unknown overtakes my fantasies. I have always wanted get a hotel room by myself (pretending I'm single) and have my partner (pretending to be a stranger) come in while I'm asleep and wake me up with sex. No lights, pitch black. He could be anyone. I'd love it even more if I woke up tied and blindfolded.
