AVSA-008 Mako Saeki, a masochistic married woman I found on a dating site

The manager enjoys perverse training with his masochistic mistress (a married woman and former subordinate). The wife is not satisfied with ordinary soft SM, so today she tries something a little more unusual and undergoes her first anal training. Fig enemas, anal finger insertion, anal dildo expansion, and anal ball insertion make her excited by sex. A real documentary that eventually develops into a two-hole threesome!
