DBNK-073 - Inside the house, showing my mother my erection... could it lead to manual stimulation!? 4 hours

She looks like an ordinary older woman, but when she sees a penis, the mature woman becomes erotic! While spending time in front of my mother in an outfit that unintentionally reveals my erection, I receive manual stimulation attacks from above my pants, get undressed, and receive fellatio, with my mother's saliva making my erection wet. The son unintentionally says "I'm going to cum!" and reaches climax with intense fellatio, sucking out thick semen.
