A middle-aged couple who moved in without knowing that it was an apartment where SM lovers gather. Yumi Anno, a sexless and frustrated wife, is attracted to the word SM and makes a contract to become a common property for the residents. As a ritual, a bitch puts on a collar and urinates, gets a piggy nose hook on her beautiful face and is shamefully attacked, and gets fucked by two cocks in a restraint 3P by the residents! M-shaped restraint torture, torture and whipping, peeing climax sex... I'm going to be captivated by SM pleasures as many times as I can! A must-see for the first nose hook!
