Suddenly, I have a sister-in-law due to family circumstances! "What a hassle," I thought, living a lazy daily life. Then, an M-cup goddess, Yuria, appeared before me! "You can be more spoiled. I am your sister-in-law after all." Ahhhh! An angel came to me, who was feeling gloomy in the Reiwa era! Maybe because I helped a bullied turtle in my past life?! Yuria, with her incredibly deep cleavage, keeps shaking her boobs, teasing me. Yeah, she's definitely teasing me! So, I got a rock-hard cock sandwiched between her M-cups, and she jerked me off, leading to an instant explosion! Damn, this feels a billion times better than masturbating! Yuria is cumming, but now it's my turn to make her cum! I really want to fuck her! Wouldn't you want to experience the happiness of being wrapped in her overflowing motherly tits? Wait, who's that? Yuria's boyfriend? Ex? Affair partner? "Whoever you are, wait a minute! Want to join us for a 3P?" I'm troubled by my suddenly appearing, overly sexy sister-in-law! Ultimate cleavage!
