[Prison] Okusan, Regi Toushitenai Shouhin Arimasu yo ne?

Single mom with 8yo kid who shoplifted due to poverty but got caught by the store manager who blackmailed her for sex. Then offered to provide food in return for sex. Lady found her life getting easier and soon enjoyed the sex. When her kid is away on play date, she realised she could no longer satisfy herself and man has not visited her for a few days due to busy store. She asked him out to a hotel and they had great sex. The ex husband realised there is another man in their life now.

a good rapist

I believe the lady is raising the girl alone and she shoplifts. The guy blackmails her and begins to bang her, then he starts to feel bad for them and starts helping them out while still banging the mom(seems she starts to enjoy it). The other dude that comes around is the ex-husband who isn't helping at all.

This needs a translation or some hero commentor to explain the chronology because I am confused.
