GVG-302 Hard! The life of stopping Mizuki Hayakawa

One day, my father brings home a young woman. She's beautiful and has a great body, and I'm turned on by her, but I hold back because she's my father's girlfriend... but then she starts playing with my dick! She teases me and makes me hard over and over again, but she never lets me cum. Can I endure the hell of my wicked girlfriend's teasing every day?
