1) A sexual position with a single partner where visual and auditory stimuli are temporarily deadened. At that point in time one is in a superposition where penetration is occurring in all orifices simultaneous. Upon the return of auditory and visual stimuli, the wave form collapses and only one orifice is being penetrated.
2) A Ménage à trois (Three-Way) with a temporary removal of audio an d visual stimuli. Requires penetration. Upon the removal of audio and visual stimuli one partner is simultaneously penetrating the two other partners until the return of the audio and visual stimuli. At that point, the wave form collapses and only one partner is chosen for penetration.

2) "So the three of us were having sex last night. I covered my ears and turned of the lights. I was in the middle of a Schrödinger's Three Way!"
