Overnight session

An overnight session is an extended session in which the submissive spends a whole evening and night with the dominant.

Such a session will often involve a certain amount of session play, followed by a longer period of confinement or bondage, during which the submissive is kept in isolation, possibly involving sensory deprivation, to sleep. The following morning, the submissive will be released and may have some further session play before the session ends.
