Dumped by her boyfriend, she ends up getting trashed at a solo drinking session. A salaryman returning home from work finds her passed out, unable to walk straight. After learning she missed the last train, he invites her back to his place, despite her initial hesitation. With nothing else to do at this late hour, she reluctantly agrees. Once inside his apartment, there's only one thing left to do. Ruka, already half-way there, immediately starts sucking his cock, even managing to make him cum inside her mouth. At this point, there's no turning back - they end up taking a bath together.
