When my son was a student, I unexpectedly met Natsuki, a female teacher who kindly gave me advice on his career path, at a soapland. "Please keep this a secret from your son." Excited by the immoral situation of sharing a secret, the two of them don't just stay in the store, but invite her to their home while their son is away for sex! Although she tries to end the relationship at first, the married female teacher, unable to suppress her sexual desire despite having a husband, visits her home again and resumes their secret creampie sex.
