嫁の母親に中出ししてしまった

It's been a year since I married my wife. She's been asking for a child soon, but I've been captivated by the lewd body of my mother-in-law, who lives with me. Even though I know it's wrong, I find myself staring at my beautiful mother-in-law. One day, I just happened to come across my mother-in-law getting changed, and I peeked fascinatedly at her as she took off her clothes, piece by piece, until she was in her underwear. Living with such a lewd mother-in-law, it's no wonder my crotch explodes!
