I wake up naked on my day off with only a hazy memory of the night before. Then my cute adult junior colleague Ria greets me while cleaning up the leftover drinks and snacks in my apartment. I cannot understand why she is there until I notice a used condom in the trash. I ask her to explain exactly what happened while we were drunk—and, if she is willing, to let me have sex with her again so her sensitive, orgasm-filled reactions can bring the missing memories back.
