Imagine your OTP - In a band and they're recording an album. One night, after everyone else has gone home, Person A persuades Person B to have a little naughty fun with them in one of the recording booths. Unfortunately, someone left the mic on, and when their bandmates come in the next morning, the find that everything's been recorded.

(Bonus points if one of the other band members wants to use it as a hidden track on the album.)
