28 yr old Tanaja Iori has not had much luck in love after she left the man who was having an affair with her. After getting too drunk, she is taken home by someone at the bar she was drinking in and wakes up naked to her the next morning. She finds out that the tattooed and somewhat pierced girl is an 18 yr old named Minami. The next day she comes upon Minami in the park and see's that she has been beaten up by, what she thinks is, her abusive boyfriend and quickly invites her to live with her. And sotheir life begins with Minami. always wanting sex and Iori almost always agreeing with her. Later there’s a secondary couple who gets introduced who are another delinquent and a feisty class rep.

Fuso-roi No Renri or Rationalism of Irregularities, is a more in your face yuri manga series where of MC jumps into bed within the first half dozen panels, ok, she was drunk but she barely hesitates in her feelings after that. We have another one of the older/younger matchup's (why does is always seem to be a 10-year gap?) with the younger being the delinquent and almost the more responsible one.

I recommend Fuso-roi No Renri if you like yuri or shoujo ai. The chapters are quite short, but it delivers the comedy, fluff and also intimate scenes well.
