ADN-461 The husband can't get an erection, the lewd wife secretly has sex with the fit young student

I'm a college student sharing a room with my brother. No money, no girlfriend. Meanwhile, a young couple moves in next door. My wife is an incredibly beautiful woman… I thought she was such a beauty, someone I had no relationship with. However, when we passed each other in the hallway, I was stared at by those big round eyes… Something inside me burst at her smile.
