The Real World (1992) : 5x17

There's a full moon over the Miami house, bringing sexual tension between the roommates to a head. Mike brings home a waitress for some fun in the Jacuzzi, and the two are joined by Melissa. The threesome quickly moves upstairs to the privacy of the bathroom, but it is obvious to Dan, Flora and Sarah that something wild is going on inside. Sarah tries to push Flora through the bathroom window to get a better look, but the window breaks, shattering the mood. Later on, Melissa and Mike deny that anything happened.
