S1 exclusive actress ' Riri Nanatsumori' makes a surprise visit to the home of a masochistic man! For 24 hours, she plays with him, teases him, fucks him and makes him cum as much as she likes, with absolutely no script! A fully improvised, real slut-bashing documentary! She steps on his masochistic dick with her beautiful legs while blaming him with dirty talk, slaps him in the face repeatedly, takes him for a walk on a leash, has sex with him in complete submission, and if he fails to hold back from ejaculating, she gives him a brutal handjob until he squirts! It's a plan to fulfill his wish list, but she's not too opposed to it... in fact, she's having more fun being a slut than ever before!
