GVH-336 - 義父と嫁、密着中出し交尾 水谷心音

I bought this after seeing the cover. I like Mizutani's expression while being pinned down by an old man—it's hard to tell if she's disgusted or ecstatic. It was erotic and great to see her progress from 'helping with training' pranks to sex, and finally begging for her father-in-law's body with a seductive voice right next to her husband.
