When I went to the reunion, I found out that a classmate I used to like had gotten married and become a housewife. Sitting next to me, she became defenseless and showed her underwear freely as she got drunk. Noticing my erect penis, which hadn't experienced a woman in 30 years, she, perhaps due to her usual dissatisfaction, tightly gripped my penis under the table. Our sexual desires ignited, and we had sex in the bathroom and in hidden corners of the store.
