My girlfriend Kokoro is cute, has big breasts, and has an excellent figure. I'm good friends with my friends and we always play together. Perhaps because Kokoro is close to people and less cautious, even though she has big breasts, she doesn't wear a bra or wears clothes that expose her big breasts, so it seems that my friends were sneaking a peek at Kokoro's breasts, and when I wasn't on a business trip, they tried to invite Kokoro over...
