I found out that my childhood friend, who I had never thought of as a woman, had hidden big breasts, so I asked her to have sex on the spot.

Riko has been close to her family since she was a child, and she is a childhood friend who has been close to each other. Since we've been growing up together for a long time, I've never seen her as a "woman" with the feeling of being a male friend. But one day, when I suddenly saw the cleavage of Riko's big breasts, I only realized she was a woman. I can't believe such defenseless big breasts were close to me... Before I knew it, I couldn't stay there anymore. I can't help but want to have sex with my childhood friend! Please, Riko! Let me do it!
