HUNTB-401 "I can't hold back anymore! I'll go with you." Although my father's new wife is young and beautiful... it turns out she's also a senior from my hometown who's infamous for being extremely promiscuous...

I feel like the new mother my father brought here looks familiar. When I thought that, she had changed a lot from the old days, but I noticed that she was a locally famous Yariman senior! My senior is a bimbo who seems to be almost a hole brother in the school, and I have been indebted only once. When such a mother-in-law continued to have sexless days with her father, her mother-in-law, who could not suppress her instincts, began to seduce her. I've Been Trying To Fill My Unsatisfied Libido!
