SSIS-389 Her girlfriend, who is active as an idol, is cuckolded by a giant senior's horse riding press and falls for pleasure Riko Kasumi

My proud girlfriend is an idol in Tokyo. It's been a long time since I've been back to my hometown, so I can't help but have fun. While she was at home, a senior who she didn't really like came to visit. Ah, I wonder if you can come home early. picture? You can't just go buy some food! But I can't say anything back. I reluctantly went shopping, but I didn't expect to be raped by a giant senior.
