This game features characters that use sleep (natural or induced with sleeping pills) to achieve sexual relationships with others and other situations that somehow manage to combine sleep with sex (pretending to sleep for seducing etc.) More often than not it is done with the intention not to wake the sleeping. Do not mix it with Wake-Up Sex - since that is about sex mostly after waking up.
