MIUM-587 Elegant secretary wife seduced at Futakotamagawa mall, creampie at mansion

A producer finds a well-dressed wife at a large shopping center in Futakotamagawa and learns she is married to a health equipment company president, though she works as a secretary elsewhere and is unsatisfied at night because her husband's penis is modest. He visits her luxury home under the pretense of giving a massage, then moves the action to the sofa, table, and kitchen while she fights to stay quiet on the phone with her husband. She is creampied and left trembling.
