Kisaragi, an announcer in the news department, is the first girlfriend I've ever had as an Amateur virgin. When I took off her clothes, I was surprised to see that she had a slim body with beautiful big breasts. Wait a minute...! I couldn't imagine it from her clothes, but when I saw her fair body with big breasts and a slim waist that would put a gravure model to shame, I couldn't think of anything else to think about other than sex. What's more, my senior, who has a lot of life experience, has amazing sexual techniques! Although we've just started dating, we love each other so much that we have sex all day long without even realizing it!
